This is mostly a rebase of Sharat's patches [2] on the tip of msm-next branch. Changes from v4: - Squashed a patch to another one to fix Jonathan's comment - Add back the pm_runtime_get_if_in_use() check Changes from v3: - Rebased on top of Jonathan's patch which adds support for changing gpu freq through hfi on newer targets - As suggested by Rob, left the icc_path intact for pre-a6xx GPUs [1] https://kernel.googlesource.com/pub/scm/linux/kernel/git/vireshk/pm/+log/opp/linux-next/ [2] https://patchwork.freedesktop.org/series/75291/ Sharat Masetty (6): dt-bindings: drm/msm/gpu: Document gpu opp table drm: msm: a6xx: send opp instead of a frequency drm: msm: a6xx: use dev_pm_opp_set_bw to scale DDR arm64: dts: qcom: SDM845: Enable GPU DDR bw scaling arm64: dts: qcom: sc7180: Add interconnects property for GPU arm64: dts: qcom: sc7180: Add opp-peak-kBps to GPU opp .../devicetree/bindings/display/msm/gpu.txt | 28 ++++++ arch/arm64/boot/dts/qcom/sc7180.dtsi | 9 ++ arch/arm64/boot/dts/qcom/sdm845.dtsi | 9 ++ drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 108 ++++++++++++--------- drivers/gpu/drm/msm/adreno/a6xx_gpu.h | 2 +- drivers/gpu/drm/msm/msm_gpu.c | 3 +- drivers/gpu/drm/msm/msm_gpu.h | 3 +- 7 files changed, 112 insertions(+), 50 deletions(-)
