From 7b610f1fbed2ab3b82a6064a2b5dedf061f31fa6 Mon Sep 17 00:00:00 2001 From: Manasi Navare Date: Wed, 28 Nov 2018 12:26:12 -0800 Subject: [PATCH] drm/i915/dp: Add DSC params and DSC config to intel_crtc_state Basic DSC parameters and DSC configuration data needs to be computed for each of the requested mode during atomic check. 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 Link: https://patchwork.freedesktop.org/patch/msgid/20181128202628.20238-1-manasi.d.navare@intel.com --- 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 645c2bb..42704e7 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_fixed.h" #include "i915_params.h" diff --git a/drivers/gpu/drm/i915/intel_drv.h b/drivers/gpu/drm/i915/intel_drv.h index 40edb21..5577f0f 100644 --- a/drivers/gpu/drm/i915/intel_drv.h +++ b/drivers/gpu/drm/i915/intel_drv.h @@ -942,6 +942,15 @@ 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 { -- 2.7.4
