* 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

* libpmc: Use known pmc_cpuid buffer sizeRyan Moeller2020-07-281-17/+7
| | | | | | | | | | | | | | | | | Use the existing PMC_CPUID_LEN to size pmc_cpuid in the kernel and various buffers for reading it in libpmc. This avoids some extra syscalls and malloc/frees. While in here, use strlcpy to copy a user-provided cpuid string instead of memcpy, to make sure we terminate the buffer. Reviewed by: mav MFC after: 1 week Sponsored by: iXsystems, Inc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BERI stands for Bluespec Extensible RISC Implementation, based on MIPS. BERI has not implemented standard MIPS perfomance monitoring counters, instead it provides statistical counters. BERI statcounters have a several limitations: - They can't be written - They don't support start/stop operation - None of hardware interrupt is provided on a counter overflow. So make it separate to hwpmc_mips module and support process/system counting mode only. Sponsored by: DARPA, AFRL Notes: svn path=/head/; revision=352487

It does not help that gcc's implementation of this warning is even more trigger-happy, in the sense that it already warns on the declaration itself, not when you are using it. This is very annoying with our use of -Wsystem-headers. That should really be disabled for gcc. Notes: svn path=/projects/clang900-import/; revision=352435

| | | | | | | | | | | | | The default package use to be FreeBSD-runtime but it should only contain binaries and libs enough to boot to single user and repair the system, it is also very handy to have a package that can be tranform to a small mfsroot. So create a new package named FreeBSD-utilities and make it the default one. Also move a few binaries and lib into this package when it make sense.
