The CCS is linear and has 4 bits of data for each main surface cache line pair, a ratio of 1:256. Additional Clear Color information is passed from the user-space through an offset in the GEM BO. Add a new modifier to identify and parse new Clear Color information and extend Gen12 render decompression functionality to the newly added modifier. v2: Fix has_alpha flag for modifiers, omit CC modifier during initial plane config(Matt). Fix Lookup error. v3: Fix the panic while running kms_cube Cc: Dhinakaran Pandiyan Cc: Ville Syrjala Cc: Shashank Sharma Cc: Rafael Antognolli Cc: Matt Roper Cc: Nanley G Chery Signed-off-by: Radhakrishna Sripada --- drivers/gpu/drm/i915/display/intel_display.c | 52 +++++++++++++++++++ .../drm/i915/display/intel_display_types.h | 3 ++ drivers/gpu/drm/i915/display/intel_sprite.c | 11 +++- drivers/gpu/drm/i915/i915_reg.h | 12 +++++ 4 files changed, 77 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index 4971c296f951..822237e98f00 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -1919,6 +1919,10 @@ intel_tile_width_bytes(const struct drm_framebuffer *fb, int color_plane) if (color_plane == 1) return 64; /* fall through */ + case I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS_CC: + if (color_plane == 1 || color_plane == 2) + return 64; + /* fall through */ case I915_FORMAT_MOD_Y_TILED: if (IS_GEN(dev_priv, 2) || HAS_128_BYTE_Y_TILING(dev_priv)) return 128; @@ -2060,6 +2064,7 @@ static unsigned int intel_surf_alignment(const struct drm_framebuffer *fb, return 256 * 1024; return 0; case I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS: + case I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS_CC: return 16 * 1024; case I915_FORMAT_MOD_Y_TILED_CCS: case I915_FORMAT_MOD_Yf_TILED_CCS: @@ -2265,6 +2270,8 @@ static bool is_surface_linear(u64 modifier, int color_plane) return true; case I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS: return color_plane == 1; + case I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS_CC: + return color_plane == 1 || color_plane == 2; case I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS: return color_plane == 1 || color_plane == 3; default: @@ -2458,6 +2465,7 @@ static unsigned int intel_fb_modifier_to_tiling(u64 fb_modifier) case I915_FORMAT_MOD_Y_TILED_CCS: case I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS: case I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS: + case I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS_CC: return I915_TILING_Y; default: return I915_TILING_NONE; @@ -2511,6 +2519,25 @@ static const struct drm_format_info gen12_ccs_formats[] = { .cpp = { 1, 1, 2, 1}, .hsub = 2, .vsub = 2, .is_yuv = true }, }; +/* + * Gen-12 compression uses 4 bits of CCS data for each cache line pair in the + * main surface.
