drm/xe/pmu: Add GT frequency events
Define PMU events for GT frequency (actual and requested). The
instantaneous values for these frequencies will be displayed.
Following PMU events are being added:
xe_0000_00_02.0/gt-actual-frequency/ [Kernel PMU event]
xe_0000_00_02.0/gt-requested-frequency/ [Kernel PMU event]
Standard perf commands can be used to monitor GT frequency:
$ perf stat -e xe_0000_00_02.0/gt-requested-frequency,gt=0/ -I1000
1.001229762 1483 Mhz xe_0000_00_02.0/gt-requested-frequency,gt=0/
2.006175406 1483 Mhz xe_0000_00_02.0/gt-requested-frequency,gt=0/
v2: Use locks while storing/reading samples, keep track of multiple
clients (Lucas) and other general cleanup.
v3: Review comments (Lucas) and use event counts instead of mask for
active events.
v4: Add freq events to event_param_valid method (Riana)
v5: Use instantaneous values instead of aggregating (Lucas)
v6: Obtain fwake at init for freq events as well and use non fwake
variant method for reading requested freq to avoid lockdep issues (Lucas)
v7: Review comments (Rodrigo, Lucas)
