Thanks for testing and merging. I still have some other patches to enable other features, on top of this. I'll repost them in hopefully logical groups. If you want them grouped in some particular way or other requirements please let me know. https://git.kernel.org/cgit/linux/kernel/git/ak/linux-misc.git/log/?h=hsw/pmu6 FWIW the outstanding patches do: - Some changes to make CPU event aliases more user friendly: print aliases in perf list, avoid the need to specify cpu//, automatically enable PEBS for mem-loads/stores, Allow aliases to specify "precise" This is all not Haswell specific, but makes the TSX changes below a lot more user friendly. Most of this is actually user mode only, except for the "precise" alias changes. - TSX changes: perf stat -T, TSX event aliases, support for reporting the abort cause from PEBS, plus the user tools support for all of this - Full width counting (generally useful, but also avoids a TSX checkpoint problem) - Support TSX filtering in the the LBR, plus a workaround for the duplicated abort record. Plus also on top (not in my git tree): - Zheng's call graph lbr mode patches, to allow user mode -g without frame pointers or full dwarf. This has a few known problems, but is still useful enough that it should be available as a option. -Andi -- ak@linux.intel.com -- Speaking for myself only.
