[PowerPC] hwpmc: add support for POWER8/9 PMCs

2020-11-05T16:36:39Z

This change adds support for POWER8 and POWER9 PMCs (bare metal and pseries). All PowerISA 2.07B non-random events are supported. Implementation was based on that of PPC970.

Don't attempt to include hwpmc support for armv6, we're missing some of the

necessary support functions in cpu-v6.h, and it may be that the only armv6 platform we support (RPi, the bcm2835 SOC) is incapable of supporting hwpmc. Reported by: dim@

For armv6 and armv7, build hwpmc_armv7.c as well as the base hwpmc_arm.c.

hwpmc: remove unused pre-table driven bits for intel

2018-05-31T22:41:07Z

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.

Add aarch64 files to the hwpmc(4) module build

2015-10-23T21:09:28Z

This was probably missed because FreeBSD/arm64 did not yet support modules when aarch64 support was added to hwpmc(4). Submitted by: andrew

Implement hwpmc(4) for Freescale e500 core.

2015-04-18T21:39:17Z

This supports e500v1, e500v2, and e500mc. Tested only on e500v2, but the performance counters are identical across all, with e500mc having some additional events. Relnotes: Yes
