It can only -handle commands to power off CPUs one at a time, and it cannot process -any commands while powering on a CPU in response to an interrupt. - -The cluster suspend process reliably takes 36 us; I rounded this up to -50 us. If all CPUs enter the cluster idle state at the same time, exit -latency is actually reduced, because there is no contention in that -case. However, if only some CPUs enter the cluster idle state, behavior -is the same as for CPU idle. - -Polling delay for the power management firmware to detect a pending -interrupt is insignificant; it is less than 20 us. - -min-residency was chosen as the point where enabling the idle state -consumed no more average power than disabling the idle state at a -variety of interrupt rates. - -Signed-off-by: Samuel Holland <samuel@sholland.org> ---- - arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 26 +++++++++++++++++++ - arch/arm64/boot/dts/allwinner/sun50i-h5.dtsi | 26 +++++++++++++++++++ - 2 files changed, 52 insertions(+) - -diff --git a/arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi b/arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi -index cac47cc50..83b198d12 100644 ---- a/arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi -+++ b/arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi -@@ -61,6 +61,7 @@ cpu0: cpu@0 { - clocks = <&ccu CLK_CPUX>;
