perf vendor events intel: Fix wrong filter_band* values for uncore events
Michael reported that he could not stat following event:
$ perf stat -e unc_p_freq_ge_1200mhz_cycles -a -- ls
event syntax error: '..e_1200mhz_cycles'
\___ value too big for format, maximum is 255
Run 'perf list' for a list of valid events
The event is unwrapped into:
uncore_pcu/event=0xb,filter_band0=1200/
where filter_band0 format says it's one byte only:
# cat uncore_pcu/format/filter_band0
config1:0-7
while JSON files specifies bigger number:
"Filter": "filter_band0=1200",
all the filter_band* formats show 1 byte width:
# cat uncore_pcu/format/filter_band1
config1:8-15
# cat uncore_pcu/format/filter_band2
config1:16-23
# cat uncore_pcu/format/filter_band3
config1:24-31
The reason of the issue is that filter_band* values are supposed to be
in 100Mhz units.. it's stated in the JSON help for the events, like:
filter_band3=XXX, with XXX in 100Mhz units
This patch divides the filter_band* values by 100, plus there's couple
of changes that actually change the number completely, like:
- "Filter": "edge=1,filter_band2=4000",
+ "Filter": "edge=1,filter_band2=30",
