https://wiki.freebsd.org/FreeBSD/arm/Allwinner reports "yes" for = "cpufreq / DVFS" for A83T (and A64 and H3). But under stable/11 -r308135 powerd on a BPI-M3 (A83T) reports: powerd: no cpufreq(4) support -- aborting: No such file or directory sysctl -a does not seem to have the items for the subject area. It leaves me wondering if trying -j 5 buildworld buildkernel all the way = through would be safe on the BPI-M3 (heat sink and fan in use). I use = such long running sustained activity for a stability test, among other = things. > # uname -apKU > FreeBSD bpim3 11.0-STABLE FreeBSD 11.0-STABLE #1 r308135M: Tue Nov 1 = 22:07:22 PDT 2016 = markmi@FreeBSDx64:/usr/obj/bpim3_clang/arm.armv6/usr/src/sys/BPIM3-NODBG = arm armv6 1100506 1100506 As far as BPIM3-NODBG goes for my context: include "ALLWINNER" ident BPIM3-NODBG makeoptions DEBUG=3D-g # Build kernel with gdb(1) = debug symbols options ALT_BREAK_TO_DEBUGGER options KDB # Enable kernel debugger support # For minimum debugger support (stable branch) use: options KDB_TRACE # Print a stack trace for a = panic options DDB # Enable the kernel debugger # Extra stuff: #options VERBOSE_SYSINIT # Enable verbose sysinit = messages #options BOOTVERBOSE=3D1 #options BOOTHOWTO=3DRB_VERBOSE #options KTR #options KTR_MASK=3DKTR_TRAP ##options KTR_CPUMASK=3D0xF #options KTR_VERBOSE # Disable any extra checking for. . . nooptions DEADLKRES # Enable the deadlock resolver nooptions INVARIANTS # Enable calls of extra sanity = checking nooptions INVARIANT_SUPPORT # Extra sanity checks of = internal structures, required by INVARIANTS nooptions WITNESS # Enable checks to detect = deadlocks and cycles nooptions WITNESS_SKIPSPIN # Don't run witness on spinlocks = for speed nooptions DIAGNOSTIC nooptions MALLOC_DEBUG_MAXZONES # Separate malloc(9) zones =3D=3D=3D Mark Millard markmi at dsl-only.net
