Add software PMC support. New kernel events can be added at various location for sampling or counting. This will for example allow easy system profiling whatever the processor is with known tools like pmcstat(8). Simultaneous usage of software PMC and hardware PMC is possible, for example looking at the lock acquire failure, page fault while sampling on instructions.

Add aarch64 files to the hwpmc(4) module build This was probably missed because FreeBSD/arm64 did not yet support modules when aarch64 support was added to hwpmc(4). Submitted by: andrew 2015-10-23 21:09:28 +00:00			`.if ${MACHINE_CPUARCH} == "aarch64"`

MFtbemd: Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the source code location of the machine, the latter the binary output. In general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless we're tesitng for a specific target. The isn't even moot for i386/amd64 where there's momemntum towards a MACHINE_CPUARCH == x86, although a specific cleanup for that likely would be needed... 2010-08-23 06:13:29 +00:00			`.if ${MACHINE_CPUARCH} == "amd64"`
hwpmc: remove unused pre-table driven bits for intel Intel now provides comprehensive tables for all performance counters and the various valid configuration permutations as text .json files. Libpmc has been converted to use these and hwpmc_core has been greatly simplified by moving to passthrough of the table values. The one gotcha is that said tables don't support pentium pro and and pentium IV. There's very few users of hwpmc on _amd64_ kernels on new hardware. It is unlikely that anyone is doing low level optimization on 15 year old Intel hardware. Nonetheless, if someone feels strongly enough to populate the corresponding tables for p4 and ppro I will reinstate the files in to the build. Code for the K8 counters and !x86 architectures remains unchanged. 2018-05-31 22:41:07 +00:00			`SRCS+= hwpmc_amd.c hwpmc_core.c hwpmc_intel.c hwpmc_tsc.c`
- Support for uncore counting events: one fixed PMC with the uncore domain clock, 8 programmable PMC. - Westmere based CPU (Xeon 5600, Corei7 980X) support. - New man pages with events list for core and uncore. - Updated Corei7 events with Intel 253669-033US December 2009 doc. There is some removed events in the documentation, they have been kept in the code but documented in the man page as obsolete. - Offcore response events can be setup with rsp token.
