Hi there,
I've recently got a chance to run a rather modern CPU and mobo for a
few weeks, and since the beast is 8GB worth of RAM, I figured amd64
would fit nicely in it.
After updating to HEAD to trying usual make world/kernel magic, the
following issues arised I haven't seen previously in i386:
- SYSV{SHM,MSG,SEM} need to be compiled in kernel for 32-bit
compatibility syscalls, despite the fact corresponding modules are
available. On i386, I always stripped SYSV-style IPC stuff out of
my kernel. Question: is it theoretically possible to build
freebsd32 compat module standalone? I'd rather have all compat
stuff (linux, etc.) as a loadable modules anyways (not to mention
that I don't want to have SYSV* options in my kernel config).
- What are technical reasons why ACPI has to be compiled in kernel?
Google wasn't very helpful here for me.
Thanks.
