The following patchset is an iteration on RFC [1] where pid/tid info is
assigned to the Arm SPE synthesized samples. Two methods of tracking
pids are considered: hardware-based (using Arm SPE CONTEXT packets), and
context-switch events (from perf) as fallback.
- Patch #1 enables pid tracking using RECORD_SWITCH* events from perf.
- Patch #2 updates perf-record documentation and arm-spe recording so
that they are consistent.
- Patch #3 saves the value of SPE CONTEXT packet to the arm_spe_record
struct.
- Patch #4 enables hardware-based pid tracking using SPE CONTEXT
packets.I have tested this patch set, it works well on Hisilicon D06 board, please consider to pick up. Thanks! Leo _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
