The changes done to dpu_hw_catalog.c do exactly that. Because the patch does not add this feature bit to any of the chipsets. I think the relevant patch was lost somewhere during the rework/rebase.

I was expecting changes to the actual catlog files. Please excuse me. As we are using PINGPONG_SDM845_MASK only up to and including DPU 6.x, this is correct. I'd then suggest rephrasing this sentence to be more explicit: Add DPU_PINGPONG_DSC to PINGPONG_SDM845_MASK, which is used for all DPU < 7.0 chipsets.

DPU < 7.0.0 requires the PINGPONG block to be involved during DSC setting up. Since DPU >= 7.0.0, enabling and starting the DSC encoder engine moved to INTF with the help of the flush mechanism. Add a DPU_PINGPONG_DSC feature bit to restrict the availability of dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() on the PINGPONG block to DPU < 7.0.0 hardware, as the registers are not available [in the PINGPONG block] on DPU 7.0.0 and higher anymore. Existing call-sites to these callbacks already skip calling into them if the function pointer is NULL. Add DPU_PINGPONG_DSC feature bit to all chipset with DPU < 7.0.0. changes in v6: -- split patches and rearrange to keep catalog related files at this patch Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> --- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 6 +++--- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 4 +++- 2 files changed, 6 insertions(+), 4 deletions(-)
