mb/google/brya/var/xol: Override TDP PL1 value
Update TDP PL1 value for the DTT optimization. The new value 18W is from
internal thermal/performance team.
- tdp_pl1_override: 15 -> 18 (W)
BUG=b:336684032
BRANCH=brya
TEST=built and verified MSR PL1 value.
Intel doc #614179 introduces how to check current PL values.
[Original MSR PL1/PL2/PL4 register values for xol]
cd /sys/class/powercap/intel-rapl/intel-rapl\:0/
grep . *power_limit*
constraint_0_power_limit_uw:15000000 <= MSR PL1 (15W)
constraint_1_power_limit_uw:55000000 <= MSR PL2 (55W)
constraint_2_power_limit_uw:114000000 <= MSR PL4 (114W)
After this patch:
constraint_0_power_limit_uw:18000000
constraint_1_power_limit_uw:55000000
constraint_2_power_limit_uw:114000000
