This patch set is not dependent on any kernel patch, it bases on Ali's patch set "perf: arm-spe: Decode SPE source and use for perf c2c". Let me use a new patch set to include all relevant patches (include Ali's patches for setting data source and this patch set), will send out soon. Hope this would be easier for picking up. Thanks, Leo P.s. James' patch set for enabling SVE register is dependent on kernel changes, James is on vacation, I will monitor the latest status and update in the corresponding patch set thread.
