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.

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.

The tool is built separately in buildworld in a subdirectory rather than how other build-tools are done. Subdirectory builds in lib/libpmcstat remain broken since the tool cannot be auto-built from here.

Use proper BTOOLSPATH for build-tools path.
