pmc: convert native to jsonl and track TSC value of samples - add '-j' options to filter to enable converting native pmc log format to json lines format to enable the use of scripts and external tooling % pmc filter -j pmc.log pmc.jsonl - Record the tsc value in sampling interrupts as opposed to recording nanotime when the sample is copied to a global log in hardclock - potentially many milliseconds later. - At initialize record the tsc_freq and the time of day to give us an offset for translating the tsc values in callchain records

libpmc: fix linking with C programs Revision r334749 Added some C++ code to libpmc. It didn't change the ABI, but it did introduce a dependency on libc++. Nobody noticed because every program that in the base system that uses libpmc is also C++.

Use MACHINE_CPUARCH when checking for arm64 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

pmc(3)/hwpmc(4): update supported Intel processors to rely fully on the vendor provided pmu-events tables and sundry cleanups. The vendor pmu-events tables provide counter descriptions, default sample rates, event, umask, and flag values for all the counter configuration permutations. Using this gives us: - much simpler kernel code for the MD component - helpful long and short event descriptions - simpler user code - sample rates that won't overload the system Update man page with newer sample types and remove unused sample type.

Fix warnings with lib/libpmc * Use `MIN` instead of similar hand rolled macro. * Sort headers. * Use `errno.h` instead of `sys/errno.h`. * Wrap the argument to sizeof in parentheses for clarity. * Remove `__BSD_VISIBLE` and `_XOPEN_SOURCE` #defines to mute warnings about incompatible snprintf definitions. This fixes a number of warnings I've been seeing lately in my builds. Sort makefile variables per style.Makefile(9) (`CFLAGS`/`CWARNFLAG.gcc`) and bump `WARNS` to 3.

Another round of attempting to squelch -Wdeprecated-declarations, which has become very trigger-happy with libc++ 9.0.0. 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.
