Subject[PATCH v6 0/2] add performance reporting support to FPGA DFL drivers
Date
Hi Moritz and all,

This patchset adds performance reporting support for FPGA DFL drivers. It
introduces one pmu to expose userspace interfaces via standard perf API.
User could use standard perf tool to access perf events exposed via pmu.

This patchset is generated based on fpga/for-next branch.

Main changes from v5:
- use dev_ext_attribute instead of fme_perf_event_attr.
- use is_visible function to decide which events to expose per
hardware capability, and add event_init checking for all events.

Main changes from v4:
- rebase and clean up.
- update Kconfig for PERF_EVENTS dependency.

Main changes from v3:
- add more descriptions in doc, including how to use perf tool for these
hardware counters. (patch #1)
- use standard perf API instead of sysfs entries. (patch #2)
