This patch set has been rebased on the acme/perf/core branch with the latest commit b39c9e1b101d ("perf machine: Fix missing free of machine->kallsyms_filename"). To make building success, a compilation fixing commit [1] has been sent to LKML, this patch set is dependent on it. This patch set has been verified for both x86 perf memory events and Arm SPE events. [1] https://lore.kernel.org/lkml/20220811044341.426796-1-leo.yan@linaro.org/ Changes from v5: * Removed the patch "perf: Add SNOOP_PEER flag to perf mem data struct" (Arnaldo); * Removed the patch "perf arm-spe: Don't set data source if it's not a memory operation" which has been merged in the mainline kernel, so can dismiss merging conflict. * Rebased on the latest acme perf/core branch, no any code change compared to previous version. Changes from v4: * Included Ali's patch set for adding data source in Arm SPE samples; * Added Ian's ACK and Ali's review and test tags; * Update document for the default peer dispaly for Arm64 (Ali). Changes from v3: * Changed to display remote and local peer accesses (Joe); * Fixed the usage info for display types (Joe); * Do not display HITM dimensions when use 'peer' display, and HITM display doesn't show any 'peer' dimensions (James); * Split to smaller patches for adding dimensions of peer operations; * Updated documentation to reflect the latest GUI and stdio.
