The Handbook section is far more verbose on this, and I think that this reference in the Makefile is more as a quick reminder than a step-by-step walkthrough.

hwpmc with opteron 6128
I am trying to do a very basic thing with hwpmc on this CPU: CPU: AMD Opteron(tm) Processor 6128 (1999.05-MHz K8-class CPU) hwpmc: SOFT/16/64/0x67INT,USR,SYS,REA,WRI TSC/1/64/0x20REA K8/4/48/0x1ffINT,USR,SYS,EDG,THR,REA,WRI,INV,QUA What I am trying is: $ pmcstat -T -S instructions What I am getting is just: PMC: [FR_RETIRED_X86_INSTRUCTIONS] Samples: 0 (0.0%) , 0 unresolved and nothing else on the screen. Has anyone had a success with this class of processors? Should it be supported? Any ideas/suggestions/hints? P.S. pmccontrol -L reports a whole bunch of K8 counters, just a small random sub-sample: BU_FILL_INTO_L2 IC_FETCH IC_MISS IC_REFILL_FROM_L2 IC_REFILL_FROM_SYSTEM IC_L1_ITLB_MISS_AND_L2_ITLB_HIT IC_L1_ITLB_MISS_AND_L2_ITLB_MISS IC_MICROARCHITECTURAL_RESYNC_BY_SNOOP IC_INSTRUCTION_FETCH_STALL IC_RETURN_STACK_HIT IC_RETURN_STACK_OVERFLOW FR_RETIRED_X86_INSTRUCTIONS FR_RETIRED_UOPS FR_RETIRED_BRANCHES FR_RETIRED_BRANCHES_MISPREDICTED FR_RETIRED_TAKEN_BRANCHES FR_RETIRED_TAKEN_BRANCHES_MISPREDICTED -- Andriy Gapon ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

Re: /bin/sh = STDIN functions, var scope messing

I'm taking this to mean that redirecting to sh_f has sh_f execute in a subshell in which global_scope_var changes, but the original shell's copy is uncahnged. Curious. Which of the two behaviours is POSIXly correct? Both. As per XCU 2.12 Shell Execution Environment, each command in a multi-command pipeline may or may not be executed in a subshell environment. Behaviour different from our sh is most often encountered in the various versions of the real Korn shell (ksh88 and ksh93), which execute the last command in a pipeline in the current shell environment. If things like jobs | cat work, that can also be explained using this rule. -- Jilles Tjoelker ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
UNIVERSE_TARGET doesn't seem to work
I build kernel-toolchain and MAKE_JUST_KERNELS (often with NO_CLEAN, but not this time) as part of my pre-commit checklist. It doesn't seem to work after the switch to bmake. What am I missing?
