I'm fine with this two-patch approach, so this important new feature can be merged quicker, hopefully in the current merge window. We can add more OPPs later, after the additional testing is performed, of course if all checks out as expected. > [1] > https://lore.kernel.org/linux-rockchip/CABjd4YxqarUCbZ-a2XLe3TWJ-qjphGkyq=wDnctnEhdoSdPPpw@mail.gmail.com/T/#me92aa0ee25e6eeb1d1501ce85f5af4e58b3b13c5 > > Signed-off-by: Alexey Charkov <alchark@gmail.com> > --- > arch/arm64/boot/dts/rockchip/rk3588s.dtsi | 87 > +++++++++++++++++++++++++++++++ > 1 file changed, 87 insertions(+) > > diff --git a/arch/arm64/boot/dts/rockchip/rk3588s.dtsi > b/arch/arm64/boot/dts/rockchip/rk3588s.dtsi > index af8b932a04c1..506676985a7e 100644 > --- a/arch/arm64/boot/dts/rockchip/rk3588s.dtsi > +++ b/arch/arm64/boot/dts/rockchip/rk3588s.dtsi > @@ -360,6 +360,21 @@ cluster0_opp_table: opp-table-cluster0 { > compatible = "operating-points-v2"; > opp-shared; > > + opp-408000000 { > + opp-hz = /bits/ 64 <408000000>; > + opp-microvolt = <675000 675000 950000>; > + clock-latency-ns = <40000>; > + }; > + opp-600000000 { > + opp-hz = /bits/ 64 <600000000>; > + opp-microvolt = <675000 675000 950000>; > + clock-latency-ns = <40000>; > + }; > + opp-816000000 { > + opp-hz = /bits/ 64 <816000000>; > + opp-microvolt = <675000 675000 950000>; > + clock-latency-ns = <40000>; > + }; > opp-1008000000 { > opp-hz = /bits/ 64 <1008000000>; > opp-microvolt = <675000 675000 950000>; > @@ -392,6 +407,27 @@ cluster1_opp_table: opp-table-cluster1 { > compatible = "operating-points-v2"; > opp-shared; > > + opp-408000000 { > + opp-hz = /bits/ 64 <408000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + opp-suspend; > + }; > + opp-600000000 { > + opp-hz = /bits/ 64 <600000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-816000000 { > + opp-hz = /bits/ 64 <816000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-1008000000 { > + opp-hz = /bits/ 64 <1008000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + }; > opp-1200000000 { > opp-hz = /bits/ 64 <1200000000>; > opp-microvolt = <675000 675000 1000000>; > @@ -422,6 +458,21 @@ opp-2208000000 { > opp-microvolt = <987500 987500 1000000>; > clock-latency-ns = <40000>; > }; > + opp-2256000000 { > + opp-hz = /bits/ 64 <2256000000>; > + opp-microvolt = <1000000 1000000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-2304000000 { > + opp-hz = /bits/ 64 <2304000000>; > + opp-microvolt = <1000000 1000000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-2352000000 { > + opp-hz = /bits/ 64 <2352000000>; > + opp-microvolt = <1000000 1000000 1000000>; > + clock-latency-ns = <40000>; > + }; > opp-2400000000 { > opp-hz = /bits/ 64 <2400000000>; > opp-microvolt = <1000000 1000000 1000000>; > @@ -433,6 +484,27 @@ cluster2_opp_table: opp-table-cluster2 { > compatible = "operating-points-v2"; > opp-shared; > > + opp-408000000 { > + opp-hz = /bits/ 64 <408000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + opp-suspend; > + }; > + opp-600000000 { > + opp-hz = /bits/ 64 <600000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-816000000 { > + opp-hz = /bits/ 64 <816000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-1008000000 { > + opp-hz = /bits/ 64 <1008000000>; > + opp-microvolt = <675000 675000 1000000>; > + clock-latency-ns = <40000>; > + }; > opp-1200000000 { > opp-hz = /bits/ 64 <1200000000>; > opp-microvolt = <675000 675000 1000000>; > @@ -463,6 +535,21 @@ opp-2208000000 { > opp-microvolt = <987500 987500 1000000>; > clock-latency-ns = <40000>; > }; > + opp-2256000000 { > + opp-hz = /bits/ 64 <2256000000>; > + opp-microvolt = <1000000 1000000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-2304000000 { > + opp-hz = /bits/ 64 <2304000000>; > + opp-microvolt = <1000000 1000000 1000000>; > + clock-latency-ns = <40000>; > + }; > + opp-2352000000 { > + opp-hz = /bits/ 64 <2352000000>; > + opp-microvolt = <1000000 1000000 1000000>; > + clock-latency-ns = <40000>; > + }; > opp-2400000000 { > opp-hz = /bits/ 64 <2400000000>; > opp-microvolt = <1000000 1000000 1000000>;

Thanks to Radxa providing a sample Rock 5B to me, I'll be able to join the testing in the new few days, or maybe early next week. Looking forward to the test results. :) >> [1] >> https://lore.kernel.org/linux-rockchip/CABjd4YxqarUCbZ-a2XLe3TWJ-qjphGkyq=wDnctnEhdoSdPPpw@mail.gmail.com/T/#me92aa0ee25e6eeb1d1501ce85f5af4e58b3b13c5 >> >> Signed-off-by: Alexey Charkov <alchark@gmail.com> >> --- >> arch/arm64/boot/dts/rockchip/rk3588s.dtsi | 87 >> +++++++++++++++++++++++++++++++ >> 1 file changed, 87 insertions(+) >> >> diff --git a/arch/arm64/boot/dts/rockchip/rk3588s.dtsi >> b/arch/arm64/boot/dts/rockchip/rk3588s.dtsi >> index af8b932a04c1..506676985a7e 100644 >> --- a/arch/arm64/boot/dts/rockchip/rk3588s.dtsi >> +++ b/arch/arm64/boot/dts/rockchip/rk3588s.dtsi >> @@ -360,6 +360,21 @@ cluster0_opp_table: opp-table-cluster0 { >> compatible = "operating-points-v2"; >> opp-shared; >> >> + opp-408000000 { >> + opp-hz = /bits/ 64 <408000000>; >> + opp-microvolt = <675000 675000 950000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-600000000 { >> + opp-hz = /bits/ 64 <600000000>; >> + opp-microvolt = <675000 675000 950000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-816000000 { >> + opp-hz = /bits/ 64 <816000000>; >> + opp-microvolt = <675000 675000 950000>; >> + clock-latency-ns = <40000>; >> + }; >> opp-1008000000 { >> opp-hz = /bits/ 64 <1008000000>; >> opp-microvolt = <675000 675000 950000>; >> @@ -392,6 +407,27 @@ cluster1_opp_table: opp-table-cluster1 { >> compatible = "operating-points-v2"; >> opp-shared; >> >> + opp-408000000 { >> + opp-hz = /bits/ 64 <408000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + opp-suspend; >> + }; >> + opp-600000000 { >> + opp-hz = /bits/ 64 <600000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-816000000 { >> + opp-hz = /bits/ 64 <816000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-1008000000 { >> + opp-hz = /bits/ 64 <1008000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> opp-1200000000 { >> opp-hz = /bits/ 64 <1200000000>; >> opp-microvolt = <675000 675000 1000000>; >> @@ -422,6 +458,21 @@ opp-2208000000 { >> opp-microvolt = <987500 987500 1000000>; >> clock-latency-ns = <40000>; >> }; >> + opp-2256000000 { >> + opp-hz = /bits/ 64 <2256000000>; >> + opp-microvolt = <1000000 1000000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-2304000000 { >> + opp-hz = /bits/ 64 <2304000000>; >> + opp-microvolt = <1000000 1000000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-2352000000 { >> + opp-hz = /bits/ 64 <2352000000>; >> + opp-microvolt = <1000000 1000000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> opp-2400000000 { >> opp-hz = /bits/ 64 <2400000000>; >> opp-microvolt = <1000000 1000000 1000000>; >> @@ -433,6 +484,27 @@ cluster2_opp_table: opp-table-cluster2 { >> compatible = "operating-points-v2"; >> opp-shared; >> >> + opp-408000000 { >> + opp-hz = /bits/ 64 <408000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + opp-suspend; >> + }; >> + opp-600000000 { >> + opp-hz = /bits/ 64 <600000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-816000000 { >> + opp-hz = /bits/ 64 <816000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-1008000000 { >> + opp-hz = /bits/ 64 <1008000000>; >> + opp-microvolt = <675000 675000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> opp-1200000000 { >> opp-hz = /bits/ 64 <1200000000>; >> opp-microvolt = <675000 675000 1000000>; >> @@ -463,6 +535,21 @@ opp-2208000000 { >> opp-microvolt = <987500 987500 1000000>; >> clock-latency-ns = <40000>; >> }; >> + opp-2256000000 { >> + opp-hz = /bits/ 64 <2256000000>; >> + opp-microvolt = <1000000 1000000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-2304000000 { >> + opp-hz = /bits/ 64 <2304000000>; >> + opp-microvolt = <1000000 1000000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> + opp-2352000000 { >> + opp-hz = /bits/ 64 <2352000000>; >> + opp-microvolt = <1000000 1000000 1000000>; >> + clock-latency-ns = <40000>; >> + }; >> opp-2400000000 { >> opp-hz = /bits/ 64 <2400000000>; >> opp-microvolt = <1000000 1000000 1000000>; > > _______________________________________________ > Linux-rockchip mailing list > Linux-rockchip@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-rockchip

This introduces additional OPPs that share the same voltage as another OPP already present in the .dtsi but with lower frequency. The idea is to try and limit system throughput more gradually upon reaching the throttling condition for workloads that are close to sustainable power already, thus avoiding needless performance loss. My limited synthetic benchmarking [1] showed around 3.8% performance benefit when these are in place, other things equal (not meant to be comprehensive though).
