This is required since for certain modes, valid DSC parameters and config data might not be computed in which case compression cannot be enabled for that mode. For that reason we need to add these params and config structure to the intel_crtc_state so that if valid this state information can directly be used while enabling DSC in atomic commit. v2: * Rebase on drm-tip (Manasi) Cc: Gaurav K Singh Cc: Jani Nikula Cc: Ville Syrjala Cc: Anusha Srivatsa Signed-off-by: Manasi Navare Reviewed-by: Anusha Srivatsa --- drivers/gpu/drm/i915/i915_drv.h | 1 + drivers/gpu/drm/i915/intel_drv.h | 9 +++++++++ 2 files changed, 10 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 2d7761b8ac07..45fd7894722b 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -53,6 +53,7 @@ #include #include #include +#include #include "i915_params.h" #include "i915_reg.h" diff --git a/drivers/gpu/drm/i915/intel_drv.h b/drivers/gpu/drm/i915/intel_drv.h index 62c051098859..27d47950f438 100644 --- a/drivers/gpu/drm/i915/intel_drv.h +++ b/drivers/gpu/drm/i915/intel_drv.h @@ -931,6 +931,15 @@ struct intel_crtc_state { /* Output down scaling is done in LSPCON device */ bool lspcon_downsampling; + + /* Display Stream compression state */ + struct { + bool compression_enable; + bool dsc_split; + u16 compressed_bpp; + u8 slice_count; + } dsc_params; + struct drm_dsc_config dp_dsc_cfg; }; struct intel_crtc {
