This patchkit adds support for the Intel Skylake core PMU to perf, documented in the recently released SDM 054[1] Vol3, 17.9 and 18.12.
The main user visible feature is timed branch records, which allows to get cycle counts for individual basic blocks, and a time stamp for PEBS records which improves multi-record PEBS. The LBRs (branch records) also have been extended to 32, which allows more accurate branch sampling and deeper call stacks. v2: Fix time stamp handling with non default clock. Fix LBR freezing. Some minor cleanups. Moved user tools support for cycles into separate patchkit. -Andi [1] http://www.cps.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
