* pmc(3)/hwpmc(4): update supported Intel processors to rely fully on theMatt Macy2018-05-261-3/+4
| | | | | | | | | | | | | | | | | | 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.

* MFP4: Support for profiling dynamically loaded objects.Joseph Koshy2006-03-261-13/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel changes: Inform hwpmc of executable objects brought into the system by kldload() and mmap(), and of their removal by kldunload() and munmap(). A helper function linker_hwpmc_list_objects() has been added to "sys/kern/kern_linker.c" and is used by hwpmc to retrieve the list of currently loaded kernel modules. The unused `MAPPINGCHANGE' event has been deprecated in favour of separate `MAP_IN' and `MAP_OUT' events; this change reduces space wastage in the log. Bump the hwpmc's ABI version to "2.0.00". Teach hwpmc(4) to handle the map change callbacks. Change the default per-cpu sample buffer size to hold 32 samples (up from 16). Increment __FreeBSD_version. libpmc(3) changes: Update libpmc(3) to deal with the new events in the log file; bring the pmclog(3) manual page in sync with the code. pmcstat(8) changes: Introduce new options to pmcstat(8): "-r" (root fs path), "-M" (mapfile name), "-q"/"-v" (verbosity control). Option "-k" now takes a kernel directory as its argument but will also work with the older invocation syntax. Rework string handling in pmcstat(8) to use an opaque type for interned strings. Clean up ELF parsing code and add support for tracking dynamic object mappings reported by a v2.0.00 hwpmc(4). Report statistics at the end of a log conversion run depending on the requested verbosity level.

- Implement sampling modes and logging support in hwpmc(4). - Separate MI and MD parts of hwpmc(4) and allow sharing of PMC implementations across different architectures. Add support for P4 (EMT64) style PMCs to the amd64 code. - New pmcstat(8) options: -E (exit time counts) -W (counts every context switch), -R (print log file). - pmc(3) API changes, improve our ability to keep ABI compatibility in the future. Add more 'alias' names for commonly used events. - bug fixes & documentation. Notes: svn path=/head/; revision=147191
