Author: Roland Scheidegger <[email protected]> Date: Sat Mar 28 01:43:50 2009 +0100 i965: srgb texture fixes i965 can either do SRGBA8_REV format or SARGB8 format, but not SRGBA8. Could add SRGBA8_REV support to mesa, but simply use SARGB8 for now. While here, also add true srgb luminance / luminance_alpha support - unfortunately the published docs fail to mention which asics support this, tested on g43 so assume this works on any g4x. --- src/mesa/drivers/dri/i965/brw_defines.h | 8 +++++--- src/mesa/drivers/dri/i965/brw_wm_surface_state.c | 10 ++++++++-- src/mesa/drivers/dri/intel/intel_tex_format.c | 19 ++++++++++++++----- 3 files changed, 27 insertions(+), 10 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_defines.h b/src/mesa/drivers/dri/i965/brw_defines.h index 74dbba4..98fc909 100644 --- a/src/mesa/drivers/dri/i965/brw_defines.h +++ b/src/mesa/drivers/dri/i965/brw_defines.h @@ -367,9 +367,10 @@ #define BRW_SURFACEFORMAT_L8A8_UNORM 0x114 #define BRW_SURFACEFORMAT_I16_FLOAT 0x115 #define BRW_SURFACEFORMAT_L16_FLOAT 0x116 -#define BRW_SURFACEFORMAT_A16_FLOAT 0x117 -#define BRW_SURFACEFORMAT_R5G5_SNORM_B6_UNORM 0x119 -#define BRW_SURFACEFORMAT_B5G5R5X1_UNORM 0x11A +#define BRW_SURFACEFORMAT_A16_FLOAT 0x117 +#define BRW_SURFACEFORMAT_L8A8_UNORM_SRGB 0x118 +#define BRW_SURFACEFORMAT_R5G5_SNORM_B6_UNORM 0x119 +#define BRW_SURFACEFORMAT_B5G5R5X1_UNORM 0x11A #define BRW_SURFACEFORMAT_B5G5R5X1_UNORM_SRGB 0x11B #define BRW_SURFACEFORMAT_R8G8_SSCALED 0x11C #define BRW_SURFACEFORMAT_R8G8_USCALED 0x11D @@ -386,6 +387,7 @@ #define BRW_SURFACEFORMAT_A4P4_UNORM 0x148 #define BRW_SURFACEFORMAT_R8_SSCALED 0x149 #define BRW_SURFACEFORMAT_R8_USCALED 0x14A +#define BRW_SURFACEFORMAT_L8_UNORM_SRGB 0x14C #define BRW_SURFACEFORMAT_R1_UINT 0x181 #define BRW_SURFACEFORMAT_YCRCB_NORMAL 0x182 #define BRW_SURFACEFORMAT_YCRCB_SWAPUVY 0x183 diff --git a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c index 66ce928..2f1f4c5 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c +++ b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c @@ -140,8 +140,14 @@ static GLuint translate_tex_format( GLuint mesa_format, GLenum internal_format, case MESA_FORMAT_RGBA_DXT5: return BRW_SURFACEFORMAT_BC3_UNORM; - case MESA_FORMAT_SRGBA8: - return BRW_SURFACEFORMAT_R8G8B8A8_UNORM_SRGB; + case MESA_FORMAT_SARGB8: + return BRW_SURFACEFORMAT_B8G8R8A8_UNORM_SRGB; + + case MESA_FORMAT_SLA8: + return BRW_SURFACEFORMAT_L8A8_UNORM_SRGB; + + case MESA_FORMAT_SL8: + return BRW_SURFACEFORMAT_L8_UNORM_SRGB; case MESA_FORMAT_SRGB_DXT1: return BRW_SURFACEFORMAT_BC1_UNORM_SRGB; diff --git a/src/mesa/drivers/dri/intel/intel_tex_format.c b/src/mesa/drivers/dri/intel/intel_tex_format.c index ce33cdc..3322a71 100644 --- a/src/mesa/drivers/dri/intel/intel_tex_format.c +++ b/src/mesa/drivers/dri/intel/intel_tex_format.c @@ -1,5 +1,6 @@ #include "intel_context.h" #include "intel_tex.h" +#include "intel_chipset.h" #include "main/texformat.h" #include "main/enums.h" @@ -160,15 +161,23 @@ intelChooseTextureFormat(GLcontext * ctx, GLint internalFormat, case GL_SRGB8_EXT: case GL_SRGB_ALPHA_EXT: case GL_SRGB8_ALPHA8_EXT: - case GL_SLUMINANCE_EXT: - case GL_SLUMINANCE8_EXT: - case GL_SLUMINANCE_ALPHA_EXT: - case GL_SLUMINANCE8_ALPHA8_EXT: case GL_COMPRESSED_SRGB_EXT: case GL_COMPRESSED_SRGB_ALPHA_EXT: case GL_COMPRESSED_SLUMINANCE_EXT: case GL_COMPRESSED_SLUMINANCE_ALPHA_EXT: - return &_mesa_texformat_srgba8; + return &_mesa_texformat_sargb8; + case GL_SLUMINANCE_EXT: + case GL_SLUMINANCE8_EXT: + if (IS_G4X(intel->intelScreen->deviceID)) + return &_mesa_texformat_sl8; + else + return &_mesa_texformat_sargb8; + case GL_SLUMINANCE_ALPHA_EXT: + case GL_SLUMINANCE8_ALPHA8_EXT: + if (IS_G4X(intel->intelScreen->deviceID)) + return &_mesa_texformat_sla8; + else + return &_mesa_texformat_sargb8; case GL_COMPRESSED_SRGB_S3TC_DXT1_EXT: case GL_COMPRESSED_SRGB_ALPHA_S3TC_DXT1_EXT: case GL_COMPRESSED_SRGB_ALPHA_S3TC_DXT3_EXT: _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
