| | | | | | | | | | | | | | | | | | - 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 Notes: svn path=/head/; revision=334749

* hwpmc: remove unused pre-table driven bits for intelMatt Macy2018-05-311-2097/+1
| | | | | | | | | | | | | | | | | | | Intel now provides comprehensive tables for all performance counters and the various valid configuration permutations as text .json files. Libpmc has been converted to use these and hwpmc_core has been greatly simplified by moving to passthrough of the table values. The one gotcha is that said tables don't support pentium pro and and pentium IV. There's very few users of hwpmc on _amd64_ kernels on new hardware. It is unlikely that anyone is doing low level optimization on 15 year old Intel hardware. Nonetheless, if someone feels strongly enough to populate the corresponding tables for p4 and ppro I will reinstate the files in to the build. Code for the K8 counters and !x86 architectures remains unchanged. Notes: svn path=/head/; revision=334456

* Replace the PMC class struct copy with an explicit memcpy()Justin Hibbits2018-01-131-1/+2
| | | | | | | | | | | | | This should be effectively a nop for all archs, but for some reason the codegen difference on the PowerPC 970 is such that the struct assignment doesn't work (unless a printf() using one of the elements in the copied struct follows it), while the memcpy() succeeds. On all archs the memcpy() should be expanded to an inline copy, since the copy is bounded to ~16 bytes. MFC after: 3 weeks Notes: svn path=/head/; revision=327911
* lib: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-265-0/+10
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326219
