Add a dpu cap to indicate this and do not expose compressed formats in this case. changes since RFC: - use ubwc enc and dec version of mdss_data instead of catalog to decide if ubwc is supported Signed-off-by: Abhinav Kumar Reviewed-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/601392/ Signed-off-by: Rob Clark --- diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c index 1c3a2657450c..40c4dd2c3139 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c @@ -18,6 +18,7 @@ #include #include "msm_drv.h" +#include "msm_mdss.h" #include "dpu_kms.h" #include "dpu_formats.h" #include "dpu_hw_sspp.h" @@ -1342,10 +1343,14 @@ void dpu_plane_danger_signal_ctrl(struct drm_plane *plane, bool enable) static bool dpu_plane_format_mod_supported(struct drm_plane *plane, uint32_t format, uint64_t modifier) { + struct dpu_kms *dpu_kms = _dpu_plane_get_kms(plane); + bool has_no_ubwc = (dpu_kms->mdss->ubwc_enc_version == 0) && + (dpu_kms->mdss->ubwc_dec_version == 0); + if (modifier == DRM_FORMAT_MOD_LINEAR) return true; - if (modifier == DRM_FORMAT_MOD_QCOM_COMPRESSED) + if (modifier == DRM_FORMAT_MOD_QCOM_COMPRESSED && !has_no_ubwc) return dpu_find_format(format, qcom_compressed_supported_formats, ARRAY_SIZE(qcom_compressed_supported_formats));
