Re: [PATCH] arm64: dts: qcom: sdm660: Fix CPU capacities

dings/arm/cpus.txt?h=LA.UM.7.2.c25#n216 вт, 12 янв. 2021 г. в 13:51, Danny Lin : sdm660 has a big.LITTLE 4+4 CPU setup with CPUs 0-3 being little cores and CPUs 4-7 being big cores. The big cores have higher IPC, so they should have the higher capacity-dmips-mhz, not the other way around as

[PATCH 2/3] arm64: dts: qcom: sm8150: Add PSCI idle states

worth noting that the CPU has an additional C3 power collapse idle state between WFI and rail power collapse (with PSCI mode 0x4003), but it is not officially used in downstream kernels due to "thermal throttling issues." Signed-off-by: Danny Lin --- arch/arm64/boot/dts/qcom/s
