Use it to enable evdev support. uinput and evdev modules should be kld-loaded or compiled into the kernel in that case. bthidd_evdev_support rc.conf variable is added to control enabling of evdev support in bthidd startup script. Possible values are: "YES", "NO", "AUTO"(default). Setting bthidd_evdev_support to "AUTO" inserts "-u" option if kernel is compiled with EVDEV_SUPPORT option enabled. Support for consumer HID usage page keyboard events is implemented. Most of them are available only through evdev protocol. kern.evdev.rcpt_mask sysctl is checked, so "sysctl kern.evdev.rcpt_mask=12" should be executed if EVDEV_SUPPORT is compiled into kernel. It is recommended to regenerate bthidd.conf entries with bthidcontrol(8) "Query" command to set user-friendly names of bluetooth devices.

As described in r283981, retire the -l legacy option. The -B and -L options were originally added to set the endianness of v3 records emitted by pwd_mkdb, but they also set the db hash endiannes and so have been retained temporarily. Announced on the FreeBSD-Current and FreeBSD-Stable lists. In stable/11 the man page contains a deprecation notice, and pwd_mkdb will emit a deprecation notice if the -l option is specified.

This commit adds a new debug server to bhyve. Unlike the existing -g option which provides an efficient connection to a debug server running in the guest OS, this debug server permits inspection and control of the guest from within the hypervisor itself without requiring any cooperation from the guest. It is similar to the debug server provided by qemu. To avoid conflicting with the existing -g option, a new -G option has been added that accepts a TCP port. An IPv4 socket is bound to this port and listens for connections from debuggers. In addition, if the port begins with the character 'w', the hypervisor will pause the guest at the first instruction until a debugger attaches and explicitly continues the guest. Note that only a single debugger can attach to a guest at a time. Virtual CPUs are exposed to the remote debugger as threads. General purpose register values can be read for each virtual CPU. Other registers cannot currently be read, and no register values can be changed by the debugger. The remote debugger can read guest memory but not write to guest memory. To facilitate source-level debugging of the guest, memory addresses from the debugger are treated as virtual addresses (rather than physical addresses) and are resolved to a physical address using the active virtual address translation of the current virtual CPU. Memory reads should honor memory mapped I/O regions, though the debug server does not attempt to honor any alignment or size constraints when accessing MMIO. The debug server provides limited support for controlling the guest. The guest is suspended when a debugger is attached and resumes when a debugger detaches. A debugger can suspend a guest by sending a Ctrl-C request (e.g. via Ctrl-C in GDB). A debugger can also continue a suspended guest while remaining attached. Breakpoints are not yet supported. Single stepping is supported on Intel CPUs that support MTRAP VM exits, but is not available on other systems. While the current debug server has limited functionality, it should at least be usable for basic debugging now. It is also a useful checkpoint to serve as a base for adding additional features.

This is definitely "early" work and there are still many things to improve. Note that if you aren't using a file gdb you will need to explicitly set the architecture.

Stepping will only work on Intel CPUs currently and not AMD. (Implementing single-stepping on AMD will prove "interesting" as it will mean raising single-step debug exceptions in the guest and then hiding them from the guest as well as properly shadowing the TF flag in %rflags in the guest and injecting suitable DB# exceptions in the guest if it is also tracing itself, etc.) There is a lot more to work on, but I think this is a useful initial checkpoint. Note that just as with the debug server in QEMU, kgdb does not currently know how to enumerate kernel threads on top of the virtual CPU "threads", so commands like 'tid' and 'proc' will not work if using kgdb. -- John Baldwin From owner-svn-src-head@freebsd.org Tue May 1 15:33:22 2018 Return-Path: Delivered-To: svn-src-head@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 2D09FFAE74F; Tue, 1 May 2018 15:33:22 +0000 (UTC) (envelope-from gallatin@FreeBSD.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "mxrelay.nyi.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id D2D6480A92; Tue, 1 May 2018 15:33:21 +0000 (UTC) (envelope-from gallatin@FreeBSD.org) Received: from repo.freebsd.org (repo.freebsd.org [IPv6:2610:1c1:1:6068::e6a:0]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id CC52623F03; Tue, 1 May 2018 15:33:21 +0000 (UTC) (envelope-from gallatin@FreeBSD.org) Received: from repo.freebsd.org ([127.0.1.37]) by repo.freebsd.org (8.15.2/8.15.2) with ESMTP id w41FXLKd084623; Tue, 1 May 2018 15:33:21 GMT (envelope-from gallatin@FreeBSD.org) Received: (from gallatin@localhost) by repo.freebsd.org (8.15.2/8.15.2/Submit) id w41FXLpo084622; Tue, 1 May 2018 15:33:21 GMT (envelope-from gallatin@FreeBSD.org) Message-Id: <201805011533.w41FXLpo084622@repo.freebsd.org> X-Authentication-Warning: repo.freebsd.org: gallatin set sender to gallatin@FreeBSD.org using -f From: Andrew Gallatin Date: Tue, 1 May 2018 15:33:21 +0000 (UTC) To: src-committers@freebsd.org, svn-src-all@freebsd.org, svn-src-head@freebsd.org Subject: svn commit: r333141 - head/sys/dev/cxgbe X-SVN-Group: head X-SVN-Commit-Author: gallatin X-SVN-Commit-Paths: head/sys/dev/cxgbe X-SVN-Commit-Revision: 333141 X-SVN-Commit-Repository: base MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit X-BeenThere: svn-src-head@freebsd.org X-Mailman-Version: 2.1.25 Precedence: list List-Id: SVN commit messages for the src tree for head/-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 01 May 2018 15:33:22 -0000 Author: gallatin Date: Tue May 1 15:33:21 2018 New Revision: 333141 URL: https://svnweb.freebsd.org/changeset/base/333141 Log: Optionally panic when cxgbe encounters a fatal error Sometimes it is better to panic than to leave a machine unreachable.

Summary of changes for version 20180427: + + +1) ACPICA kernel-resident subsystem: + +Debugger: Added support for Package objects in the "Test Objects" +command. This command walks the entire namespace and evaluates all named +data objects (Integers, Strings, Buffers, and now Packages). + +Improved error messages for the namespace root node. Originally, the root +was referred to by the confusing string "\___". This has been replaced by +"Namespace Root" for clarification. + +Fixed a potential infinite loop in the AcpiRsDumpByteList function. Colin +Ian King . + + +2) iASL Compiler/Disassembler and Tools: + +iASL: Implemented support to detect and flag illegal forward references. +For compatibility with other ACPI implementations, these references are +now illegal at the root level of the DSDT or SSDTs. Forward references +have always been illegal within control methods. This change should not +affect existing ASL/AML code because of the fact that these references +have always been illegal in the other ACPI implementation. + +iASL: Added error messages for the case where a table OEM ID and OEM +TABLE ID strings are longer than the ACPI-defined length. Previously, +these strings were simply silently truncated. + +iASL: Enhanced the -tc option (which creates an AML hex file in C, +suitable for import into a firmware project): + 1) Create a unique name for the table, to simplify use of multiple +SSDTs. + 2) Add a protection #ifdef in the file, similar to a .h header file. +With assistance from Sami Mujawar, sami.mujawar@arm.com and Evan Lloyd, +evan.lloyd@arm.com + +AcpiExec: Added a new option, -df, to disable the local fault handler. +This is useful during debugging, where it may be desired to drop into a +debugger on a fault. + +---------------------------------------- 13 March 2018.

When do > you think that'll be possible? I think I can speak to Randall's plans for this. Randall chose not to include in this commit the hooks for the default stack to use the high-precision timers. I believe his immediate priorities are upstreaming RACK and BBR. After that, if there is demand, he may upstream the (relatively untested) code that allows the default stack to use the high-precision timers (protected by a non-default kernel option) so others can choose to experiment with it. (By the way, we're hoping to change the terminology away from describing the traditional FreeBSD stack as the "default" stack. In theory, someone can make any stack be their local default.

On FreeBSD ioctls have the size of the passed struct encoded in the ioctl number, because the generic ioctl handler in the OS takes care of copying the data from user-space to kernel space, and then calls the device specific ioctl handler. Thus using ioctl structs with variable sizes is not possible. The fix is to turn the array of structs at the end of ioctl_gntdev_alloc_gref and ioctl_gntdev_map_grant_ref into pointers, that can be properly accessed from the kernel gntdev driver using the copyin/copyout functions. Note that this is exactly how it's done for the privcmd driver.

An apparently common pattern is: timer = timerfd_create(...); ... fcntl(timer->fd, F_SETFL, O_NONBLOCK); This fcntl(2) call will fail and result in an ENOTTY, because libepoll-shim's implementation of timerfd_create is a wrapper around kqueue and this isn't an OK thing to do. This was the inspiration of one of the specifically mentioned examples. epoll API provides a way to set NONBLOCK in the creation process, the use of which in lieu of the timerfd_create ... fcntl pattern ended up being the proper fix.

In addition - even on a production kernel it's possible to compile in DDB to at least get a backtrace. Your report only gives us enough information to know that there is _an_ issue. It's difficult to proceed on this alone. I do have a report from the FreeBSD CI infrastructure that we're looking in to now. With luck that is the same issue. -M On Thu, May 3, 2018 at 12:31 PM, O.

I disabled it by default in r323615, and there was some confusion about what the knob does- likely due to poor naming on my part- to the tune of "well, it sounds like it should speed things up" (mentioned by multiple people). To compound this, I have no intention of maintaining a second regex implementation. If someone would like to step up and volunteer to maintain a lean-and-mean implementation for grep, this is OK, but we have very few volunteers to maintain even our primary regex implementation.

In r309610 and r315514 the behavior of handling EACCES was changed, and tcp_output() now returns zero when EACCES happens. The reason of this change was a hesitation that applications that use TCP-MD5 will be affected by changes in project/ipsec. TCP-MD5 code returns EACCES when security assocition for given connection is not configured. But the same error code can return pfil(9), and this change has affected connections blocked by pfil(9). E.g. application doesn't return immediately when SYN segment is blocked, instead it waits when several tries will be failed. Actually, for TCP-MD5 application it doesn't matter will it get EACCES after first SYN, or after several tries. Security associtions must be configured before initiating TCP connection. I left the EACCES in the switch() to show that it has special handling.

This code carefully tracked txq and rxq, and made sure to free them properly during cleanup. Because we assigned the txq and rxq pointers into the ctx->ifc_txqs and ctx->ifc_rxqs, we carefully reset these pointers to NULL, so that cleanup code would not accidentally free the memory twice. This was changed by r304021 ("Update iflib to support more NIC designs"), which removed this resetting of the pointers to NULL, because it re-used the txq and rxq pointers as an index into the queue set array. Unfortunately, the cleanup code was left alone. Thus, if we fail to allocate DMA or fail to configure the queues using the drivers ifdi methods, we will attempt to free txq and rxq. These variables would now incorrectly point to the wrong location, resulting in a page fault. There are a number of methods to correct this, but ultimately the root cause was that we reuse the txq and rxq pointers for two different purposes. Instead, when allocating, store the returned pointer directly into ctx->ifc_txqs and ctx->ifc_rxqs. Then, assign this to txq and rxq as index pointers before starting the loop to allocate each queue. Drop the cleanup code for txq and rxq, and only use ctx->ifc_txqs and ctx->ifc_rxqs. Thus, we no longer need to free txq or rxq under any error flow, and intsead rely solely on the pointers stored in ctx->ifc_txqs and ctx->ifc_rxqs. This prevents the invalid free(), and ensures that we still properly cleanup after ourselves as before when failing to allocate.

An earlier attempt to make this work was done in r320456, by always reading the pad status register (PSR) instead of the data register. But it turns out the values in PSR only reflect the electrical level of an output pin if the pad is configured with the SION (Set Input On) bit in the pinmux config, and most output gpio pads are not configured that way. So now a gpio read is done by returning the value from the data register, which works right whether the pin is configured for input or output, unless the pin has been set for OPENDRAIN mode, in which case the PSR is read instead. For this to work, the pin must also be configured with SION turned on in the fdt pinmux data, which is a reasonable thing to require for the unusual case of reading an open-drain output pin.

With r332974, when performing a synchronized access of a page's "queue" field, one must first check whether the page is logically dequeued. If so, then the page lock does not prevent the page from being removed from its page queue. Intoduce vm_page_queue(), which returns the page's logical queue index. In some cases, direct access to the "queue" field is still required, but such accesses should be confined to sys/vm.

We probably should also explicitly release any resources cached in sc->vga_bios and sc->vga_bars. In theory they should be clear by the time bus_generic_detach finishes, but perhaps we should walk the resources and whine if they aren't released and then release them. -- John Baldwin From owner-svn-src-head@freebsd.org Fri May 4 19:28:06 2018 Return-Path: Delivered-To: svn-src-head@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 306CBFB5DB9; Fri, 4 May 2018 19:28:06 +0000 (UTC) (envelope-from ian@FreeBSD.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "mxrelay.nyi.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id D85647B454; Fri, 4 May 2018 19:28:05 +0000 (UTC) (envelope-from ian@FreeBSD.org) Received: from repo.freebsd.org (repo.freebsd.org [IPv6:2610:1c1:1:6068::e6a:0]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id B527D13240; Fri, 4 May 2018 19:28:05 +0000 (UTC) (envelope-from ian@FreeBSD.org) Received: from repo.freebsd.org ([127.0.1.37]) by repo.freebsd.org (8.15.2/8.15.2) with ESMTP id w44JS51i094032; Fri, 4 May 2018 19:28:05 GMT (envelope-from ian@FreeBSD.org) Received: (from ian@localhost) by repo.freebsd.org (8.15.2/8.15.2/Submit) id w44JS5vo094031; Fri, 4 May 2018 19:28:05 GMT (envelope-from ian@FreeBSD.org) Message-Id: <201805041928.w44JS5vo094031@repo.freebsd.org> X-Authentication-Warning: repo.freebsd.org: ian set sender to ian@FreeBSD.org using -f From: Ian Lepore Date: Fri, 4 May 2018 19:28:05 +0000 (UTC) To: src-committers@freebsd.org, svn-src-all@freebsd.org, svn-src-head@freebsd.org Subject: svn commit: r333260 - head/sys/arm/freescale/imx X-SVN-Group: head X-SVN-Commit-Author: ian X-SVN-Commit-Paths: head/sys/arm/freescale/imx X-SVN-Commit-Revision: 333260 X-SVN-Commit-Repository: base MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit X-BeenThere: svn-src-head@freebsd.org X-Mailman-Version: 2.1.25 Precedence: list List-Id: SVN commit messages for the src tree for head/-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 04 May 2018 19:28:06 -0000 Author: ian Date: Fri May 4 19:28:05 2018 New Revision: 333260 URL: https://svnweb.freebsd.org/changeset/base/333260 Log: Properly support the GPIO_PIN_PRESET_{LOW,HIGH} options when configuring a gpio pin.

A good commit messages starts with a sentence or two that summarizes what's been changed, followed by some non-zero amount of extra information that says why (for all but the most trivial self-obvious changes). This is pretty good on the "why". Consider how this is going to look buried in the output of "svn log kern.mk" (or on svnweb.freebsd.org) when you're skimming through the commit history looking for what changed while you're tracking down some problem. When you run into this commit in the log, you're going to have no option but to stop what you're doing and look at the diff to see if it's germane to your search, because of the missing summary information. -- Ian From owner-svn-src-head@freebsd.org Fri May 4 20:38:27 2018 Return-Path: Delivered-To: svn-src-head@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 6A9FAFB75CE; Fri, 4 May 2018 20:38:27 +0000 (UTC) (envelope-from gjb@FreeBSD.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "mxrelay.nyi.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 1DC2A7D473; Fri, 4 May 2018 20:38:27 +0000 (UTC) (envelope-from gjb@FreeBSD.org) Received: from repo.freebsd.org (repo.freebsd.org [IPv6:2610:1c1:1:6068::e6a:0]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 1491A13DA9; Fri, 4 May 2018 20:38:27 +0000 (UTC) (envelope-from gjb@FreeBSD.org) Received: from repo.freebsd.org ([127.0.1.37]) by repo.freebsd.org (8.15.2/8.15.2) with ESMTP id w44KcQQk028909; Fri, 4 May 2018 20:38:26 GMT (envelope-from gjb@FreeBSD.org) Received: (from gjb@localhost) by repo.freebsd.org (8.15.2/8.15.2/Submit) id w44KcQJs028908; Fri, 4 May 2018 20:38:26 GMT (envelope-from gjb@FreeBSD.org) Message-Id: <201805042038.w44KcQJs028908@repo.freebsd.org> X-Authentication-Warning: repo.freebsd.org: gjb set sender to gjb@FreeBSD.org using -f From: Glen Barber Date: Fri, 4 May 2018 20:38:26 +0000 (UTC) To: src-committers@freebsd.org, svn-src-all@freebsd.org, svn-src-head@freebsd.org Subject: svn commit: r333262 - head/release/tools X-SVN-Group: head X-SVN-Commit-Author: gjb X-SVN-Commit-Paths: head/release/tools X-SVN-Commit-Revision: 333262 X-SVN-Commit-Repository: base MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit X-BeenThere: svn-src-head@freebsd.org X-Mailman-Version: 2.1.25 Precedence: list List-Id: SVN commit messages for the src tree for head/-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 04 May 2018 20:38:27 -0000 Author: gjb Date: Fri May 4 20:38:26 2018 New Revision: 333262 URL: https://svnweb.freebsd.org/changeset/base/333262 Log: Ensure the ports and src trees are available on GCE images, satisfying a requirement to allow FreeBSD to be considered a top-tier supported OS in Google Compute Engine.

This sort of message doesnt provide anything more that can be obtained from reading the diff, which just leaves us wondering why? I=E2=80=99m sure there is a good reason, but without confirmation we=E2=80= =99re just left guessing. The knock on to this is if some assumption that caused the why changes, anyone looking at this will not be able to make an informed descision that that was the case.

But if we know for a fact they don't overlap (like here), doing this over memcpy (which does not accept such buffers) only puts avoidable constraints on the optimizer. This is a rather pedestrian change which can be made in many places, I don't see the point of repeating the explanation in each one.

Though this makes sense at the present time when one is reading commits one after the other, in 2 years time when I am looking at just the log file of just one of the effected files that context is lost, so please document things in a way that the information in the log is usefull, part of the purpose of the log is to help us locate and to understand why something was done to the code. It is really rather painful to be reading logs and have to do 30 svn diffs rXXXXX to see what the log entry is trying to explain, and in this case even that does not tell why it was done. > > > On Fri, 4 May 2018 at 23:41, Mateusz Guzik wrote: > > > >> Author: mjg > >> Date: Fri May 4 22:41:12 2018 > >> New Revision: 333266 > >> URL: https://svnweb.freebsd.org/changeset/base/333266 > >> > >> Log: > >> amd64: syscall path bcopy -> memcpy > >> > >> Modified: > >> head/sys/amd64/amd64/trap.c > >> > >> Modified: head/sys/amd64/amd64/trap.c > >> ============================================================ > >> ================== > >> --- head/sys/amd64/amd64/trap.c Fri May 4 22:33:54 2018 (r333265) > >> +++ head/sys/amd64/amd64/trap.c Fri May 4 22:41:12 2018 (r333266) > >> @@ -908,7 +908,7 @@ cpu_fetch_syscall_args(struct thread *td) > >> error = 0; > >> argp = &frame->tf_rdi; > >> argp += reg; > >> - bcopy(argp, sa->args, sizeof(sa->args[0]) * 6); > >> + memcpy(sa->args, argp, sizeof(sa->args[0]) * 6); > >> if (sa->narg > regcnt) { > >> KASSERT(params != NULL, ("copyin args with no params!")); > >> error = copyin(params, &sa->args[regcnt], > >> > >> > > > -- > Mateusz Guzik -- Rod Grimes rgrimes@freebsd.org From owner-svn-src-head@freebsd.org Fri May 4 23:44:50 2018 Return-Path: Delivered-To: svn-src-head@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 92DD9FBBCE6 for ; Fri, 4 May 2018 23:44:50 +0000 (UTC) (envelope-from juli@northcloak.com) Received: from mail-qt0-x22d.google.com (mail-qt0-x22d.google.com [IPv6:2607:f8b0:400d:c0d::22d]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (Client CN "smtp.gmail.com", Issuer "Google Internet Authority G2" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 2E9006E5D5 for ; Fri, 4 May 2018 23:44:49 +0000 (UTC) (envelope-from juli@northcloak.com) Received: by mail-qt0-x22d.google.com with SMTP id m9-v6so8824116qtb.5 for ; Fri, 04 May 2018 16:44:49 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=northcloak-com.20150623.gappssmtp.com; s=20150623; h=mime-version:in-reply-to:references:from:date:message-id:subject:to :cc; bh=aaP2NRbHR2gjVqG9rFDivwEQtTQ+WTm9lT/VmdPuCQA=; b=nSaP31APHUmjzt1juCQP36cqM4UX05aUGzFST7wgnmkySfzxNOhgIW+9dr/3psEaDX XZN2veWrP3BGdAdTO3HdFAq9+MuO5USfLvMCkt5rKNOojOhBhCMCGgFE+eKoIMVTZA9u o6zdYCujKsNLhM3ync1XLBonRFGGAaU9CkEyWnCDo8sxUmpTLW6HWS8oIpq5ZD7gsFlZ 2YinMLMH2fJRFFSjbZyV6VCuw0xDiK1hA2QNt8PA1N4V+lINwrXrL2Jx9J3ppGjG+R0y r79ZGYO7p6da4EkDHlWsC/j1Pn317KjlkshG8u1mGlnXMJXDliXFjutI9P3blhXc5Qpt h7Og== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:mime-version:in-reply-to:references:from:date :message-id:subject:to:cc; bh=aaP2NRbHR2gjVqG9rFDivwEQtTQ+WTm9lT/VmdPuCQA=; b=B6t1ehqORU4dV13beOjhCvKDBdnLkVs81a20+38T8JERITmzmeUYO6z1FZ22E7NU3J acOraY+woS+dIxrJt544h3qt9UJWVMfdqLznuoQE7yYyDy8KgFHsRNZ0EliYqG8kTTPa zS50QgcCpyF68BupYUqivuU+paV7dMuuwzpsUWOUt28UDTWq7D/R28cRTgkt8I+hwIIP 550O6Bg3skz2Ei1wATJsvr/Zo7eCjEhfv2s0ZvZT4uti6rTzSzcNtpToQDpJjDiAz2r8 NitjMDAcDIwdZills9YgyimM5qQnf5fkXwSBsmiPQtZ19EyI02wj2mcpCiEXsMgWVCW7 FiXQ== X-Gm-Message-State: ALQs6tAPLNwjFl3CG8r/3g7Aj+XNKroRr1NVE0TLMY88ZjMm8B7DvhEQ //UahSz1FkGig0Ypati/7/bZoiAaXmcEDyyjNQ2DXQ== X-Google-Smtp-Source: AB8JxZovzZcmaIXKowLZMca2mLmEpzAf22pkP70bQnyQev5lT1B3mDbCl+j64GCXU76b5V1sF0GZj9rZfQ9JbzamyXA= X-Received: by 2002:aed:23a1:: with SMTP id j30-v6mr15510498qtc.361.1525477489609; Fri, 04 May 2018 16:44:49 -0700 (PDT) MIME-Version: 1.0 Received: by 10.200.69.23 with HTTP; Fri, 4 May 2018 16:44:09 -0700 (PDT) In-Reply-To: References: <201805042241.w44MfC9E090893@repo.freebsd.org> From: Juli Mallett Date: Fri, 4 May 2018 16:44:09 -0700 Message-ID: Subject: Re: svn commit: r333266 - head/sys/amd64/amd64 To: Mateusz Guzik Cc: Steven Hartland , Mateusz Guzik , src-committers , svn-src-all@freebsd.org, svn-src-head@freebsd.org Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Content-Filtered-By: Mailman/MimeDel 2.1.25 X-BeenThere: svn-src-head@freebsd.org X-Mailman-Version: 2.1.25 Precedence: list List-Id: SVN commit messages for the src tree for head/-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 04 May 2018 23:44:50 -0000 On 4 May 2018 at 16:12, Mateusz Guzik wrote: > On Sat, May 5, 2018 at 12:58 AM, Steven Hartland < > steven.hartland@multiplay.co.uk> wrote: > >> Can we get the why in commit messages please? >> >> This sort of message doesnt provide anything more that can be obtained >> from reading the diff, which just leaves us wondering why? >> >> I=E2=80=99m sure there is a good reason, but without confirmation we=E2= =80=99re just left >> guessing.

Today it's more like memmove, but at times in the history of BSD/Unix it's be more akin to memcpy with a companion ovbcopy used for overlapping copies. FreeBSD has almost always been more in the 'bcopy is memmove' rather than the 'bcopy is memcpy' though some of the lower-tier architectures pulled in ovbcopy which we recently GC'd from NetBSD and/or OpenBSD. Plus there's been an irrational encouragement of using bcopy over mem* which has lead to the current state of affairs. For the vast majority of uses, it hasn't really mattered much in the past. It hasn't shown up on radar. However, as its optimization has moved into the compiler I'm guessing that's changed. It's that change of heart I think that are taking people by surprise.

I think the compiler can't use its builtin bcopy() in standalone mode. Not quite. Builtin bcopy() doesn't exist even for clang (5.0.1) in hosted mode. But the question was about using __builtin_memmove(). This exists for both gcc and clang, but doesn't work right: - for gcc4.2.1, __builtin_memmove() never works right. It always falls back to memmove(). This is broken in the -ffreestanding case, since memmove() can be anything then. Actually, in the kernel a function named memmove(9) exists and has the same semantics as memmove(3), but is slightly slower. So the effect of the change for gcc-4.2.1 is to pessimize the case that was supposed to be optimized: fixed-sized moves of size <= 64 are pessimized to use memmove() instead of bcopy(), while other args still use bcopy(). - for clang-5.0.1, on x86 for most -march settings, SSE is used even with -ffreestanding. The kernel uses various -m flags to prevent use of SSE and the FPU. This forces the compiler to copy through integer registers. This reduces the number of cases that must be analyzed to see how broken the hard-coded 64 is: - with AVX present and not killed, inlining occurs up to size 256 (8 pairs of vmovups through 256-bit registers) - else with SSE present and not killed, inlining occurs up to size 128 (8 pairs of movaps through 128-bit registers). This also depends on other CPU capabilitities. E.g., this uses movaps instead of movups since movups is slower on the target CPU (core2) even in the aligned case, while vmovups doesn't have this problem. - the above cases don't apply in the kernel - on 64-bit arches, inlining occurs up to size 64 (8 pairs movq through 64-bit integer registers) - on 32-bit arches, inlining occurs up to size 64 (8 pairs movq through 32-bit integer registers). So the effect of the change for clang is to pessimize half of the cases that were supposed to be optimized on i386 (and probably similarly on other 32-bit arches): fixed-sized moves of size > 32 and <= 64 are pessimized to use memmove() instead of bcopy(). Summary: this change wouldn't have passed my review. I have used similar changes for 15-20 years but never made them production quality since there are too many variations to consider and testing showed insignificant improvements except for micro-benchmarks. This change should be harmless if done right. E.g., it could spell 64 as (8 * sizeof(register_t)) so as to not pessimize i386 and probably similarly on other 32-bit arches. It is still too chummy with the implementations. x86 compilers used to get this wrong too, and probably still do except when they can use AVX. gcc got it wrong 20-30 years ago on i386 by inlining to "rep movsl" up to sizes much larger than 32. Eventually it learned that it didn't understand memory and left this to the library. Now on x86 CPUs that have "fast-strings", inlined "rep movsb" is better than most libraries. x86 kernel "libraries" still reduce to "rep movs*" plus lots of extra instructions that more than double the overhead. With fast-strings, the problem with using "rep movsb" is almost entirely in its overhead. On Haswell, IIRC, it takes 25 cycles to start up. Then it copies 32 bytes per cycle if both the source and the target are in the L1 cache. So the copy size must be 25 * 32 = 800 just to amortize half of the startup overhead. Even copying through 32-bit integer registers is much faster than that. There are often cache misses so that all methods are slow, but micro-benchmarks rarely cover the slow cases. I don't believe the claimed speeding of using the optimized bcopy() in cpu_fetch_sycall_args() on amd64 (r333241). This changes the copy size from a variable to 6*8 bytes. It is claimed to speed up getppid() from 7.31M/sec to 10.65M/sec on Skylake. But here it and other changes in the last week give a small pessimization for getpid() on Haswell at 4.08GHz: last week, 100M getpid()'s took 8.27 seconds (12.09M/sec). Now they take 8.30 seconds (12.05M/sec). (This is with very old libraries, so there is no possibility of getpid() being done in userland.) 0.03 seconds is 122.4M cycles. So the speed difference is 1.224 cycles. Here the timing has a resolution of only 0.01 seconds, so most digits in this 1.224 are noise, but the difference is apparently a single cycle. I would have expected more like the "rep movs*" setup overhead of 25 cycles. Another way to look at this is: 12.09M/sec syscalls means 82.71 nsec or 337 cycles each. Not too bad. The cache latency for this system according to lmbench-2.0 is 1 nsec for L1, 4.5 nsec for L2, and 16.3 nsec for main memory (old lmbench doesn't understand L3...). 66 cycles for main memory. I don't quite believe that. 100-200 cycles is more common. I think Skylake is slightly slower. Anyway, there can't be many cache misses in 337 cycles. We can hope for improvements of ~25 cycles each by avoiding "rep movs*" instructions. bcopy() actually has 2 of these (it ends up with 1 rep movsb which is null except in misaligned cases. This started being pessimal with the i486 and is relatively worse with fast-strings). However, fixes in this area rarely make as much difference as hoped for, except possibly on in-order arches. On Haswell and Skylake, everything is pipelined so it extra cycles in bcopy() don't matter provided nothing depends on the result very soon, and nearby code is equally inefficient and the resources used by the bcopy() don't contend too much with the resources used by the nearby code. Resources used by bcopy() do contend a lot in practice, but not 100%.

A quick test in userland on freefall gives: - 22.81 seconds for 10**9 bcopy()s of 128 bytes (75 cycles each; bandwidth 5.61G/sec) - 23.43 seconds for 10**9 mymemmove()s of 128 bytes where mymemmove() == kernel wrapper of bcopy() (77.3 cycles each; bandwidth 5.46G/sec) but that was only for the first run. On another run, the bcopy()s took 23.11 seconds and the mymmemove()s took 22.62 seconds. So the errors in the measurement are much larger than the 2-cycle difference. Nevertheless, I expect the difference to be about 2 cycles or 3%. Most of the bandwidth is wasted by both methods. gcc inlines memcpy() to 16 movq pairs and this takes 4.38 to 5.16 seconds (it tends to get faster with every run, which I suspect is due to SCHED_ULE affinity not understanding HTT but getting better with training -- I have been fixing this in SCHED_4BSD). - 4.38 seconds for 10**9 memcpys()s of 128 bytes (14.5 cycles each; bandwidth 29.22G/sec) Even without fancy -march, clang inlines memcpy() to movaps on vanilla amd64 since SSE is available: - 2.84-2.89 seconds for 10**9 memcpys()s of 128 bytes (9.4 cycles each; bandwidth 45.07G/sec). clang does a weird optimization for my counting loop unless its counter is declared volatile -- it doesn't optimize the loop to a single copy, but reduces the count by 10 each iteration instead of the expected 1 or everything. Semi-semi-finally, with -march=native to get AVX instead of SSE: - 1.65-1.88 seconds for 10**9 memcpys()s of 128 bytes (5.5 cycles each; bandwidth 77.57G/sec). This is still far short of the 128-non-disk-manufacturersG that is reached by Haswell at 4GHz using simple "rep movsb". The size is too small to amortize the overhead. Semi-finally, with AVX and the size doubled to 256 bytes: - 2.98-3.06 seconds for 10**9 memcpys()s of 256 bytes (9.8 cycles each; bandwidth 85.90G/sec). Finally, with the size increased to 4K and the count reduced to 10M: - 0.62-0.66 seconds for 10**7 memcpys()s of 4K bytes (204.6 cycles each; bandwidth 66.02G/sec). Oops, that wasn't final. It shows that freefall's Xeon behaves much like Haswell. The user library is clueless about all this and just uses "rep movsq" and even 4K is too small to amortize the startup overhead of not-so-fast-strings. With the size increased to 8K and the count kept at 10M: - 1.12-1.16 seconds for 10**7 memcpys()s of 8K bytes (369.6 cycles each; bandwidth 73.14G/sec). This almost reaches the AVX bandwidth. But the bandwidth is only this high with both the source and the target in the L1 cache. Doubling the size again runs out of L1. So there is no size large enough to amortize the ~25 cycle startup overhead of not-so-fast-strings. > These limits will get lifted after the fallback routines get sorted out. They should be left out to begin with. Any hard-coded limits are sure to be wrong for many cases. E.g., 32 is wrong on i386. Using __builtin_memmove() at all is a pessimization for gcc-4.2.1, but that can be fixed (reduced to a null change) by sorting out memmove().

(The first change has more technical complications and was copied from a similar change for bzero() and is has smaller bugs -- it is not missing parentheses for args, but is missing them for the nested bcopy() call like for the nested bzero() call (this looks like an endlessly recursive call and parentheses should be used to clarify that it isn't).) memcpy() might tbe faster than bcopy() since it doesn't have to work for overlapped copies. But when both reduce to builtins, in cases like the above the compiler should be able to see that the copies don't overlap and further reduce to inlined memcpy() in both cases. This shows another reason why it is wrong to not reduce bcopy() to __builtin_memmove() in all cases -- it prevents the compiler further reducing to memcpy() in the non-inlined case. bcopy() and memcpy() are almost equally pessimal on x86, but bcopy() is inherently slower. Unfortunately, there are compiler bugs in this area. -ffreestanding -mno-sse -m32 breaks __builtin_memmove() with both clang and gcc for a struct copy of size 36. For a struct copy, the result is just bad code: - gcc-4.2.1 generates 9 pairs of movl's through integer registers. Too many I think. - clang generates "rep movsl". This is much slower than even the large code generated by gcc. __builtin_memcpy() instead of __builtin_memmove() generates the same not so good code as for a struct copy. Adjusting the above analysis for this gives: - changing the struct copy to memcpy() has no effect - using __builtin_memmove() to implement bcopy() suffers from compiler bugs. The compiler not only fails to reduce to __builtin_memcpy() in most cases - the second change above does have an effect since it bypasses the compiler bugs. Further examples of the compiler bugs: - __builtin_memmove() with size 36 does work with clang on amd64 with -ffreestanding -mno-sse (but no -m32). So the kernel implementation works OK on amd64 with clang. I thought that the limit was 32 for all of these functions. The limit should obviously be larger with larger registers including AVX. In these tests, I didn't use any special inlining flags. The kernel uses expanded inlining flags which might make a difference. The -Winline flag to detect failed inlining was recently broken (removed). There should be a similar flag to detect using builtins that don't work. - __builtin_memmove() doesn't work with gcc-4.2.1 for any size on either amd64 or i386 with or without special flags (it reduces to memmove(). So the kernel implementation doesn't works on either amd64 or i386 with gcc.

[This should have been killfiled due to top-posting.] No, it has nothing to do with that. The compiler can inline either bcopy() or memcpy(), and does so after related recent changes that implement bcopy() using builtins. What this does is work around bugs in the recent changes, and compiler bugs. bcopy() handles overlapping copies, but memcpy() doesn't, so it is not just a style bug to use memcpy() instead of bcopy(). However, if bcopy() is exposed to the compiler using builtins (note that -ffreestanding prevents even memcpy() being known to the compiler unless memcpy() is spelled __builtin_memcpy(), and there are similar but larger complications for bcopy()) then the compiler can almost always see when overlap occurs and further reduce bcopy() to __builtin_memcpy(). The full reduction should be: bcopy() -> __builtin_memmove() -> __builtin_memcpy() -> { either inline code or a call to __memcpy() } but the actual reduction is: bcopy() -> { __builtin_memmove() for small sizes, else bcopy() (bug1) } -> { __builtin_memcpy() if inlined, else a call to memmove() (bugs2,3) }, else bcopy() where bug1 is an implementation bug (not telling the compiler about large copies), bug2 is a compiler bug (forgetting that it reduced to *memcpy when calling the library to handle large sizes), and bug3 is a compiler bug (calling the library function memmove() which might be unrelated in the freestanding case). Fixing the implementation and compiler would optimize thousands of calls to bcopy() without churning the source code, but I'm a bit worried about security bugs from this. The security bugs are larger for bzero(). When bzero() was not exposed to the compiler as __builtin_memset(), it was guaranteed to always zero memory so there was no need for explicit_bzero() or explicit_memset() in the kernel, and using these was just a style bug, as is using memset() to 0 instead of bzero(). Usually the compiler doesn't have enough information to optimize away __builtin_memset(). But changing thousands of bzero()s to __builtin_memset()s is likely to find a couple of cases where the compiler does do this optimization and it breaks security.

Other buses, such as acpi, carefully order their child devices to express implicit dependencies between them. For such buses it is safer to bring down devices in the reverse order. I believe that this is the reason why hpet_suspend had to be disabled. Some drivers depend on a working event timer until they are suspended. But previously we would suspend hpet very early. I tested this change by makinbg hpet_suspend actually stop HPET timers and tested that too. Note that this change is not a complete solution as it does not take into account bus passes. A better approach would be to track the actual attach order of the devices and to use the reverse of that.

It can either be S5/Reset Status register or Misc. Fix register (aka debug status register). The mode is controlled by bit 2 in PMIO register 0xc4. Apparently there are register programming requirements for the second personality, so many BIOSes leave the register, after programming it, in that mode. So, we need to switch the register to the correct mode. Additionally, AMDSB8_WD_RST_STS was defined incorrectly as bit 13 while it is actually bit 25 (and the register's width is 32 bits, not 16).

Indeed, but clang already does adequate optimization for som manye cases (especially amd64), so these small changes are not much more than special micro-optimizations for gcc on 32-bit arches.

FreeBSD has almost always been more in the I think (but don't know) that ovbcopy is a SYSVism and bcopy() always handled overlapping copies in BSD. It was not well documented that it did, but with only 1 memory-copying function that function has to handle overlapping copies or be even better documented to not handle them. > 'bcopy is memmove' rather than the 'bcopy is memcpy' though some of the > lower-tier architectures pulled in ovbcopy which we recently GC'd from > NetBSD and/or OpenBSD. In all of 4.4BSD /sys, ovbcopy is only referenced on 34 lines (almost half in tags files), mostly to implement it on some arches: - news3400, hp300, i386, luna68k: alias for bcopy - sparc64: separate from bcopy. bcopy seems to be like memcpy and doesn't handle overlapping copies. - vax/inline/machpats.c: separate and too vaxish for me to understand (seem= s to be just a prologue) - netiso/iso_pcb.c, net/slcompress.c, sparc/pmap.c. netinet/ip_output.c, netinet/ip_nroute.c: actually use it The sparc64 and vax code is an indication that bcopy didn't always handle overlapping copies in BSD. > Plus there's been an irrational encouragement of > using bcopy over mem* which has lead to the current state of affairs.

Deciding if the copies overlap takes about 1 branch, and with modern branch prediction that often costs about 1 cycle.

Amdahls' law applies and gives a limit of about 1% for the possible improvements from optimizing bcopy(), except in micro-benchmarks. That is even though the kernel spends a relatively large amount of time in bcopy(). Userland might take 80% of the time, the kernel 20%, and bcopy() 10% of the 20% =3D 2%. After optimizing bcopy(= ) to be twice as fast (which is difficult), you have speeded up applications by 1% at most.

Example of other style bugs for #define (spaces after '#' to indent). Reduction of portability here. I think zutil.h tries to provide its own wrappers for everything. It still does this for memset() although this is wrong when (n) != 0. I think you removed memcpy() since memcpy() is now implemented as an inconsistent macro, while memset() is still a function in systm.h so there is no conflict for memset(). Since there is no conflict, the bug is not even detected. memcmp() here is even more broken that memset(). memcmp() cannot be implemented using bcmp(), since it is tri-state while bcmp() is boolean. The system memcmp() had the same bug for a long time.

Key off the newly early-enabled CPU features flags for the new architecture, and configure the MMU appropriately. The POWER9 MMU ignores the "PSIZ" field in the PTCR, and expects a 64kB table. As we are enabled for powernv (hypervisor mode, no VMs), only initialize partition table entry 0, and zero out the rest. The actual contents of the register are identical to SDR1 from previous architectures. Along with this, fix a bug in the page table allocation with very large memory. The table can be allocated on any 256k boundary. The bootstrap_alloc alignment argument is an int, and with large amounts of memory passing the size of the table as the alignment will overflow an integer. Hard-code the alignment at 256k as wider alignment is not necessary.

I'll see about gcc 4.2.1 vs 32-bit archs later and other claims later. It is unclear to me whether you actually benchmarked syscall performance before and after the change nor how you measured a slowdown in getpid. This mail outlines what was tested and how. If you want, you can mail me off list and we can arrange so that you get root access to the test box and can measure things yourself, boot your own kernel and whatnot. My preferred way of measurement is with this suite: https://github.com/antonblanchard/will-it-scale Unfortunately it requires a little bit of patching to setup. Upside is cheap processing: there is a dedicated process/thread which collects results once a second, other than that the processes/threads running the test only do the test and bump the iteration counter. getppid looks like this: while (1) { getppid(); (*iterations)++; } If you are interested in trying it out yourself without getting access to the box in question I'm happy to provide a bundle which should be easily compilable. Perhaps you are using the tool which can be found here: tools/tools/syscall_timing It reports significantly lower numbers (even 20% less) because the test loop itself has just more overhead. For the first testing method results are as I wrote in the commit message, with one caveat that I disabled frequency scaling and they went down a little bit (i.e. NOT boosted freq, but having it disabled makes things tad bit slower; *boosted* numbers are significantly bigger but also not reliable). The syscall path has long standing pessimization of using a function pointer to get to the arguments. This fact was utilized to provide different implementations switchable at runtime (thanks to kgdb -w and the set command). The variants include: 1. cpu_fetch_syscall_args This is the routine as present in head, i.e. with inlined memcpy 2. cpu_fetch_syscall_args_bcopy State prior to my changes, i.e. a bcopy call with a variable size 3. cpu_fetch_syscall_args_oolmemcpy Forced to not be inlined memcpy with a constant size, the code itself is the same as for regular memcpy 4. cpu_fetch_syscall_args_oolmemcpy_es Forced to not be inlined memcpy with a constant size, the code itself was modified to utilize the 'Enhanced REP MOVSB/STOSB' bit present on Intel cpus made past 2011 or so. The code can be found here: https://people.freebsd.org/~mjg/copyhacks.diff (note: declarations where not added, so WERROR= or similar is needed to get this to compile) Variants were switched at runtime like this: # kgdb -w (kgdb) set elf64_freebsd_sysvec.sv_fetch_syscall_args=cpu_fetch_syscall_args_bcopy The frequency is fixed with: # sysctl dev.cpu.0.freq=2100 PTI was disabled (vm.pmap.pti=0 in loader.conf).

Not taking advantage of the EMRS bit can be now fixed at runtime thanks to recently landed ifunc support. bcopy code can be further depessimized: ENTRY(bcopy) PUSH_FRAME_POINTER xchgq %rsi,%rdi xchg is known to be slow, the preferred way is to swap registers "by hand". the fact that the func always has to do is is a bug on its own. Interestingly memmove *does not have* to do it, so this provides even more reasons to just remove this function in the first place. movq %rdi,%rax subq %rsi,%rax cmpq %rcx,%rax /* overlapping && src < dst? */ jb 1f Avoidable (for memcpy-compatible callers) branch, although statically predicted as not taken (memcpy friendly). shrq $3,%rcx /* copy by 64-bit words */ rep movsq movq %rdx,%rcx andq $7,%rcx /* any bytes left? */ rep movsb The old string copy. Note that reordering andq prior to rep movsb can help some microarchitectures. The movsq -> movsb combo induces significant stalls in the cpu frontend. If the target size is a multiple of 8 and is known at compilation time, we can get away with calling a variant which only deals with this case and thus avoid the extra penalty. Either way, the win *is here* and is definitely not in the range of 3%. -- Mateusz Guzik From owner-svn-src-head@freebsd.org Sat May 5 16:14:40 2018 Return-Path: Delivered-To: svn-src-head@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 1A6B1FB2465; Sat, 5 May 2018 16:14:40 +0000 (UTC) (envelope-from mjguzik@gmail.com) Received: from mail-qk0-x242.google.com (mail-qk0-x242.google.com [IPv6:2607:f8b0:400d:c09::242]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (Client CN "smtp.gmail.com", Issuer "Google Internet Authority G2" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id A183168FBC; Sat, 5 May 2018 16:14:39 +0000 (UTC) (envelope-from mjguzik@gmail.com) Received: by mail-qk0-x242.google.com with SMTP id a202so18955555qkg.3; Sat, 05 May 2018 09:14:39 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=mime-version:in-reply-to:references:from:date:message-id:subject:to :cc; bh=ZHpw9VLX3+uMNAuqU4Bzl5HZUBhwx2C2Ij4CZV2Fsak=; b=bKKxpwEBVIIpyrw8L00yEsUZx/6qCiwYNP1P4T7ufKOurFCnVe97qeiAAyVsoRvn9T Gy+53iX6vQrSVd8LBX+xEVd38bRgninRbnmduvwIeZYhcJ34sQ/AxTE2UDMxcd14BIXJ mPZO+v8JdF3HgY9jFSHxgjNoQkMjQUwuDQkcB0iybNwzQD/lWZ+DLsLKY9Jg+RZd4Qtj vb0uKJdNtSWb6WLe5BwpbiBH6Qfx5oRdSzeyzw6WuJSmxRR2AMq5wJvekMpWWBuzYY7J 2aAc/Ly3HXLLu0O3RzH9x4Tfuz60xAjMg7bZ/okglXEEalNUDN6QZYG+SpiMa0w8EL6g +mUA== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:mime-version:in-reply-to:references:from:date :message-id:subject:to:cc; bh=ZHpw9VLX3+uMNAuqU4Bzl5HZUBhwx2C2Ij4CZV2Fsak=; b=baug3NpH60/MKNBasH/jWJDD1k16jtZgXxFV/FkOutGL+iYcakTqP9hijxQA5aDruI WqEpuLIu88YWcEt1wxjnxZfUMvyhjRmLj8dnjdw73untODybRj0d4ywon2LF+pNTmE59 EWgbCNmUVWOxocDxS2MIv3EQX14YMUsc/E/0PgClTVkwbnLO8U9SjZrtQcbPoCLllAjj UZKdK9GDsCUMXpbsHaowqlDMyKrcr1RqjhXlUJDEIMwsJDmUXDST3euO9Dz1BKzxhNlR +JsZx5UrFNZAtNxX9FMygS1PqSdZwT9DLJqlDBXmE6Ikd3e7ikeVpNZgXHfHU9ucTc+E xxTA== X-Gm-Message-State: ALQs6tC2Bj7Cbr+RXfHRhnGaMEFZOFSYn0qZilPKIQdW3xHd1hGnNCbR DTrHWhYZSxuvxG5fG5/wVJlDwQ/6RV/HWweExU0= X-Google-Smtp-Source: AB8JxZqAvAe2XnaDnKsA/6WQLtJKl+qL7jGbBny/RIqBm03w+W8eOJAyQ012k/v0Tk0wMPFLw7lF7e5VEkmt90jsgqQ= X-Received: by 10.55.147.66 with SMTP id v63mr27033272qkd.40.1525536878900; Sat, 05 May 2018 09:14:38 -0700 (PDT) MIME-Version: 1.0 Received: by 10.200.28.74 with HTTP; Sat, 5 May 2018 09:14:38 -0700 (PDT) In-Reply-To: <20180505120055.GA81833@FreeBSD.org> References: <201805040400.w4440moH025057@repo.freebsd.org> <20180504155301.GA56280@spindle.one-eyed-alien.net> <20180505090954.X1307@besplex.bde.org> <20180505120055.GA81833@FreeBSD.org> From: Mateusz Guzik Date: Sat, 5 May 2018 18:14:38 +0200 Message-ID: Subject: Re: svn commit: r333240 - in head/sys: powerpc/powerpc sys To: Alexey Dokuchaev Cc: Bruce Evans , Conrad Meyer , svn-src-head@freebsd.org, svn-src-all@freebsd.org, Brooks Davis , src-committers Content-Type: text/plain; charset="UTF-8" X-Content-Filtered-By: Mailman/MimeDel 2.1.25 X-BeenThere: svn-src-head@freebsd.org X-Mailman-Version: 2.1.25 Precedence: list List-Id: SVN commit messages for the src tree for head/-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 05 May 2018 16:14:40 -0000 On Sat, May 5, 2018 at 2:00 PM, Alexey Dokuchaev wrote: > On Sat, May 05, 2018 at 10:38:29AM +1000, Bruce Evans wrote: > > ... > > Summary: this change wouldn't have passed my review.

They changed to behave like mere memcpy (i.e. assume non-overlapping buffers). This caused buggy code to run into trouble. bcopy has memmove semantics and this change keeps that. The only difference is that instead of always generating a call, the compiler is allowed to perform the copy in place in certain cases. This is precisely what happens almost everywhere and it was not happening in the kernel because of a giant hammer -fno-builtin flag (added to reduce changes the compiler will do stuff the kernel does not want to deal with). -- Mateusz Guzik From owner-svn-src-head@freebsd.org Sat May 5 18:21:51 2018 Return-Path: Delivered-To: svn-src-head@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id B2172FB5F48 for ; Sat, 5 May 2018 18:21:50 +0000 (UTC) (envelope-from mmacy@freebsd.org) Received: from smtp.freebsd.org (unknown [IPv6:2610:1c1:1:606c::24b:4]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "smtp.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 515F385810; Sat, 5 May 2018 18:21:50 +0000 (UTC) (envelope-from mmacy@freebsd.org) Received: from mail-it0-f54.google.com (mail-it0-f54.google.com [209.85.214.54]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (Client CN "smtp.gmail.com", Issuer "Google Internet Authority G2" (verified OK)) (Authenticated sender: mmacy) by smtp.freebsd.org (Postfix) with ESMTPSA id 23B8D27B09; Sat, 5 May 2018 18:21:50 +0000 (UTC) (envelope-from mmacy@freebsd.org) Received: by mail-it0-f54.google.com with SMTP id p3-v6so7051911itc.0; Sat, 05 May 2018 11:21:50 -0700 (PDT) X-Gm-Message-State: ALQs6tDYx4c321g7sWk17NSkPjvRLnKuSl6am9Qd6fNNjc0Z1MZNOvf7 D3NDoELdj3TIdML8X6aYNYvD6i9Gw9yy3Q96rX8= X-Google-Smtp-Source: AB8JxZpBk04cK9EeLND1nfqrKK2ukEiXQHFnGS0fp9tbLKK/BUUZAsCxucgclGRadK6dR2wIA8gcWJYn1sJ5z8MHAuw= X-Received: by 2002:a24:4455:: with SMTP id o82-v6mr32360001ita.4.1525544508501; Sat, 05 May 2018 11:21:48 -0700 (PDT) MIME-Version: 1.0 Received: by 2002:a02:b0c3:0:0:0:0:0 with HTTP; Sat, 5 May 2018 11:21:47 -0700 (PDT) In-Reply-To: <20180505110138.6cae0f75@thor.intern.walstatt.dynvpn.de> References: <201805021936.w42JaTlq039053@repo.freebsd.org> <20180503213206.7fba052c@thor.intern.walstatt.dynvpn.de> <20180503222419.4228e8e8@thor.intern.walstatt.dynvpn.de> <20180505110138.6cae0f75@thor.intern.walstatt.dynvpn.de> From: Matthew Macy Date: Sat, 5 May 2018 11:21:47 -0700 X-Gmail-Original-Message-ID: Message-ID: Subject: Re: svn commit: r333175 - in head/sys: kern net netinet netinet6 sys: TRAP 12 To: "O.

These firmwares and the following list of changes are from the public ChelsioUwire-3.7.1.0 release. T6 Firmware ================================================================================ Version : 1.19.1.0 Date : 04/23/2018 ================================================================================ Fixes ----- BASE: - Fixed traffic stall when rate-limit is modified while running traffic. - Fixes a firmware crash in FW_ETH_TX_EO_WR handling. - Fixes host DCB support when FW_PORT_CMD is used. ETH: - Exit Auto-Negotiation if we don't receive base page from peer within 10s. This fixes some cases where in we keep on restarting auto negotiation without ever exiting, resulting in link failure. - Fixes an issue where VF packets counter were not increasing if VF packets coalesced WR is used by driver. OFLD: - Kernel and user mode NVMEoF performance enhancements. FOiSCSI: - Fixes fw crash when trying to connect to non-existence IPv6 iSNS target. ================================================================================ Version : 1.18.9.0 Date : 03/27/2018 ================================================================================ Fixes ----- BASE: - For Ethernet frames less than 64B, pad them with zero bytes as per IEEE spec (RFC 894). - Added a new parameter iqtype to FW_IQ_CMD to identify the ingress NIC or offload queues. This fixes an issue where driver was receiving interrupt with no new messages in queue. - FW_PARAMS_CMD processes all the valaid paramaters and returns value 0UL for any unknown parameter. OFLD: - Fixes connection failure during SRQ reuse. - Fixes incorrect cqe in case of WRITE with immediate operation. FOiSCSI: - Fixes a fw crash when wrong node-id is passed to FW_FOISCSI_CTRL_WR. FOFCoE: - Fixes a fw hang while creating NPIV. Enhancements ------------ ETH: - A new WR FW_ETH_TX_PKTS_VM_WR added to support VM packet coalescing. ================================================================================ Version : 1.18.4.0 Date : 02/28/2018 ================================================================================ Fixes ----- BASE: - Fixed Rate limiting not working for 101Mbps<=rate limit<=163Mbps range. - Fixed starting more than 32 VMs on PF4 causing firmware hang. ETH: - Fixed link failure due to FEC mismatch with optics. - Fixed link failure with link toggle stress tests. - Only BaseR FEC is supported for 50G. - Fixed a bug in next page handling which sometimes causes link down. - Fixed port down due to failre to read eeprom contents of some modules. - Fixed a bug causing adapter to fail with spider configuration. FOiSCSI: - Fixed a bug causing login failure when connecting to multiple targets. Enhancements ------------ BASE: - Added a new firmware API to retrieve the maximum temperaturethreshold for the chip (FW_PARAM_DEV_DIAG_MAXTMPTHRESH). ETH: - Added support for user to contol pause negotiation during auto negotiation. FOiSCSI: - Added a new facility to redirect few fw events to offload rx queue (based on driver's configration) - Driver can ignore providing ipv6 prefix len during ipv6 address configuration. ================================================================================ Version : 1.17.14.0 Date : 12/27/2017 ================================================================================ FIXES ----- BASE: - Fixed an FLR failure during simulteneous power up of VM. - Fixed an issue in vlan acl which was limiting vlan range to 1024. ETH: - Enabled RS-FEC for 25G active copper cable and 25GBASE-SR. - When auto negotiation is enabled, final pause settings are resolved based on local and peer pause settings. - Handle NACK for an I2C access. OFLD - Fixed rdma connection cleanup in SO adpater. - Fixed rdma connections during read invalidate. - Fixed the crash when invalid BW rate is passed to fw. - Fixed the traffic hang when BW allocation is changed from switch during traffic. FOFCoE: - Fixed an issue where initiator remains logged-in even after LLDP is disabled on switch. ENHANCEMENTS ------------ BASE: - Added support for 248 VFs. - Added fw driver periodic calibration for MC. ETH: - Added XLAUI port type support. - Added raw mac entry deletion support (FW_VI_MAC_ID_BASED_FREE). OFLD: - Inline IPSec support added (flag F_FW_ULPTX_WR_DATA indicates the inline IPSec WR). - New work request FW_RI_RDMA_WRITE_CMPL_WR (write with completion) added to T5 Firmware ================================================================================ Version : 1.19.1.0 Date : 04/23/2018 ================================================================================ Fixes ----- BASE: - Fixes a firmware crash in FW_ETH_TX_EO_WR handling. - Fixes host DCB support when FW_PORT_CMD is used. ETH: - Fixes an issue where VF packets counter were not increasing if VF packets coalesced WR is used by driver. OFLD: - Fixes an issue where fw hangs if max traffic rate passed is 0. FOiSCSI: - Fixes fw crash when trying to connect to non-existence IPv6 iSNS target. ================================================================================ Version : 1.18.9.0 Date : 03/27/2018 ================================================================================ Fixes ----- BASE: - For Ethernet frames less than 64B, pad them with zero bytes as per IEEE spec (RFC 894). - Added a new parameter iqtype to FW_IQ_CMD to identify the ingress NIC or offload queues. This fixes an issue where driver was receiving interrupt with no new messages in queue. ETH: - Pad the Ethernet packets of size less than 64B with zeros. This fixes the incorrect checksum generation of packets less then 64B. FOiSCSI: - Fixes a fw crash when wrong node-id is passed to FW_FOISCSI_CTRL_WR. FOFCoE: - Fixes a fw hang while creating NPIV. Enhancements ------------ ETH: - A new WR FW_ETH_TX_PKTS_VM_WR added to support VM packet coalescing. ================================================================================ Version : 1.18.4.0 Date : 02/28/2018 ================================================================================ Fixes ----- BASE: - Fixed starting more than 32 VMs on PF4 causing firmware hang.

As it turns out, tcp_usr_detach can acquire the tcbinfo lock readonly. Trying to wunlock the pcbinfo lock in that context has caused a number of reported crashes. This change unclutters in_pcbfree and moves the handling of wunlock vs runlock of pcbinfo to the freemoptions routine.
