libpmcstat: Fix a few ARM-specific issues with function symbols.

2022-05-11T18:57:17Z

- Refine the checks for ARM mapping symbols and apply them on arm64 as well as 32-bit arm. In particular, mapping symbols can have additional characters and are not strictly limited to just "$a" but can append additional characters (e.g. "$a.1"). Add "$x" to the list of mapping symbol prefixes. - Clear the LSB of function symbol addresses. Thumb function addresses set the LSB to enable Thumb mode. However, the actual function starts at the aligned address with LSB clear. Not clearing the LSB can cause pmcannotate to pass misaligned addresses to objdump when extracting disassembly.

pmcstat: fix PPC kernel symbol resolution

2020-11-05T16:47:23Z

PowerPC kernel is of DYN type and it has a base address where it is initially loaded, before being relocated. As the start address passed to pmcstat_image_link() is where the kernel was relocated to, but the symbols always use the original base address, we need to subtract it to get the correct offset.

pmcstat: implement showing offsets into symbols in top mode

2020-08-05T19:05:49Z

The -I option (and hotkey) is reused for this. Skipping symbol resolution is moved to the new -A option (and hotkey). While arguably this violates POLA I think it's a change for the better. ALso note the -I option was added in head. Differential Revision: https://reviews.freebsd.org/D21658

libpmcstat: Try /boot/modules if module not found

2020-03-12T23:04:40Z

Modules from ports/pkg are commonly installed to /boot/modules rather than to the same directory the kernel resides in. Look there if a module is not found next to the kernel.

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.
