* pmc(3): remove Pentium-related man pages and referencesMitchell Horne2021-08-101-3/+0
| | | | | | | | | | | Support for Pentium events was removed completely in e92a1350b50e. Don't bump .Dd where we are just removing xrefs. Reviewed by: emaste MFC after: 1 week Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D31423
* libpmc: limit pmu-events to 64-bit powerpcMitchell Horne2021-05-311-1/+1
| | | | | | | | Although currently unused, there are only pmu event definitions for POWER8 and POWER9. There is no sense in building these on 32-bit platforms. Sponsored by: The FreeBSD Foundation
* libpmc: use $MACHINE_CPUARCHMitchell Horne2021-05-311-1/+1
| | | | | | | This is preferred over $MACHINE_ARCH for these types of checks, although it makes no difference for amd64 or i386. No functional change intended. Sponsored by: The FreeBSD Foundation
* libpmc: always generate libpmc_events.cMitchell Horne2021-05-311-4/+3

| | | | | | | | | | | Revision r334749 Added some C++ code to libpmc. It didn't change the ABI, but it did introduce a dependency on libc++.

* Use MACHINE_CPUARCH when checking for arm64Andrew Turner2020-09-141-2/+2
| | | | | | | | | | | | | | | Use MACHINE_CPUARCH with arm64 (aarch64) when we build code that could run on any 64-bit Arm instruction set. This will simplify checks in downstream consumers targeting prototype instruction sets. The only place we check for MACHINE_ARCH == aarch64 is when building the device tree blobs. As these are targeting current generation ISAs. Sponsored by: Innovate UK Differential Revision: https://reviews.freebsd.org/D26370 Notes: svn path=/head/; revision=365726
