From 6eba56f64d5d5ea5f273557fe46e21799a60da99 Mon Sep 17 00:00:00 2001 From: Anshuman Gupta Date: Fri, 24 Sep 2021 12:14:49 -0700 Subject: drm/i915/pxp: black pixels on pxp disabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When protected sufaces has flipped and pxp session is disabled, display black pixels by using plane color CTM correction. v2: - Display black pixels in async flip too. v3: - Removed the black pixels logic for async flip. [Ville] - Used plane state to force black pixels. [Ville] v4 (Daniele): update pxp_is_borked check. v5: rebase on top of v9 plane decryption moving the decrypt check (Juston) Cc: Ville Syrjälä Cc: Gaurav Kumar Cc: Shankar Uma Signed-off-by: Anshuman Gupta Signed-off-by: Daniele Ceraolo Spurio Signed-off-by: Juston Li Reviewed-by: Rodrigo Vivi Reviewed-by: Uma Shankar Signed-off-by: Rodrigo Vivi Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-15-alan.previn.teres.alexis@intel.com --- drivers/gpu/drm/i915/i915_reg.h | 46 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) (limited to 'drivers/gpu/drm/i915/i915_reg.h') diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 4be684b0fcd4..47bfffe0b4de 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -7260,6 +7260,7 @@ enum { #define _PLANE_COLOR_CTL_3_A 0x703CC /* GLK+ */ #define PLANE_COLOR_PIPE_GAMMA_ENABLE (1 << 30) /* Pre-ICL */ #define PLANE_COLOR_YUV_RANGE_CORRECTION_DISABLE (1 << 28) +#define PLANE_COLOR_PLANE_CSC_ENABLE REG_BIT(21) /* ICL+ */ #define PLANE_COLOR_INPUT_CSC_ENABLE (1 << 20) /* ICL+ */ #define PLANE_COLOR_PIPE_CSC_ENABLE (1 << 23) /* Pre-ICL */ #define PLANE_COLOR_CSC_MODE_BYPASS (0 << 17) @@ -11377,6 +11378,51 @@ enum skl_power_gate { _PAL_PREC_MULTI_SEG_DATA_A, \ _PAL_PREC_MULTI_SEG_DATA_B) +#define _MMIO_PLANE_GAMC(plane, i, a, b) _MMIO(_PIPE(plane, a, b) + (i) * 4) + +/* Plane CSC Registers */ +#define _PLANE_CSC_RY_GY_1_A 0x70210 +#define _PLANE_CSC_RY_GY_2_A 0x70310 + +#define _PLANE_CSC_RY_GY_1_B 0x71210 +#define _PLANE_CSC_RY_GY_2_B 0x71310 + +#define _PLANE_CSC_RY_GY_1(pipe) _PIPE(pipe, _PLANE_CSC_RY_GY_1_A, \ + _PLANE_CSC_RY_GY_1_B) +#define _PLANE_CSC_RY_GY_2(pipe) _PIPE(pipe, _PLANE_INPUT_CSC_RY_GY_2_A, \ + _PLANE_INPUT_CSC_RY_GY_2_B) +#define PLANE_CSC_COEFF(pipe, plane, index) _MMIO_PLANE(plane, \ + _PLANE_CSC_RY_GY_1(pipe) + (index) * 4, \ + _PLANE_CSC_RY_GY_2(pipe) + (index) * 4) + +#define _PLANE_CSC_PREOFF_HI_1_A 0x70228 +#define _PLANE_CSC_PREOFF_HI_2_A 0x70328 + +#define _PLANE_CSC_PREOFF_HI_1_B 0x71228 +#define _PLANE_CSC_PREOFF_HI_2_B 0x71328 + +#define _PLANE_CSC_PREOFF_HI_1(pipe) _PIPE(pipe, _PLANE_CSC_PREOFF_HI_1_A, \ + _PLANE_CSC_PREOFF_HI_1_B) +#define _PLANE_CSC_PREOFF_HI_2(pipe) _PIPE(pipe, _PLANE_CSC_PREOFF_HI_2_A, \ + _PLANE_CSC_PREOFF_HI_2_B) +#define PLANE_CSC_PREOFF(pipe, plane, index) _MMIO_PLANE(plane, _PLANE_CSC_PREOFF_HI_1(pipe) + \ + (index) * 4, _PLANE_CSC_PREOFF_HI_2(pipe) + \ + (index) * 4) + +#define _PLANE_CSC_POSTOFF_HI_1_A 0x70234 +#define _PLANE_CSC_POSTOFF_HI_2_A 0x70334 + +#define _PLANE_CSC_POSTOFF_HI_1_B 0x71234 +#define _PLANE_CSC_POSTOFF_HI_2_B 0x71334 + +#define _PLANE_CSC_POSTOFF_HI_1(pipe) _PIPE(pipe, _PLANE_CSC_POSTOFF_HI_1_A, \ + _PLANE_CSC_POSTOFF_HI_1_B) +#define _PLANE_CSC_POSTOFF_HI_2(pipe) _PIPE(pipe, _PLANE_CSC_POSTOFF_HI_2_A, \ + _PLANE_CSC_POSTOFF_HI_2_B) +#define PLANE_CSC_POSTOFF(pipe, plane, index) _MMIO_PLANE(plane, _PLANE_CSC_POSTOFF_HI_1(pipe) + \ + (index) * 4, _PLANE_CSC_POSTOFF_HI_2(pipe) + \ + (index) * 4) + /* pipe CSC & degamma/gamma LUTs on CHV */ #define _CGM_PIPE_A_CSC_COEFF01 (VLV_DISPLAY_BASE + 0x67900) #define _CGM_PIPE_A_CSC_COEFF23 (VLV_DISPLAY_BASE + 0x67904) -- cgit v1.2.3
