From f4535f6e5ae63d8c59428cf190a95e0eb4ae233d Mon Sep 17 00:00:00 2001 From: Jakob Bornecrantz Date: Fri, 6 Jun 2008 16:12:55 +0200 Subject: [PATCH] mesa: Add MESA_FORMAT_S8_Z24 texture format None of the fetch and store functions implemented. This atleast stops shadowtex from locking the GPU on i915 with the linux-dri-x86 target. It most of it looks okay, with the exception of actually displaying the texture. --- src/mesa/main/texformat.c | 35 ++++++++++++++++++++++++++++++ src/mesa/main/texformat.h | 2 ++ src/mesa/state_tracker/st_format.c | 6 +++-- 3 files changed, 41 insertions(+), 2 deletions(-) diff --git a/src/mesa/main/texformat.c b/src/mesa/main/texformat.c index 88fbd8f07c2..d479bf510ee 100644 --- a/src/mesa/main/texformat.c +++ b/src/mesa/main/texformat.c @@ -1207,6 +1207,41 @@ const struct gl_texture_format _mesa_texformat_z24_s8 = { store_texel_z24_s8 /* StoreTexel */ }; +const struct gl_texture_format _mesa_texformat_s8_z24 = { + MESA_FORMAT_S8_Z24, /* MesaFormat */ + GL_DEPTH_STENCIL_EXT, /* BaseFormat */ + GL_UNSIGNED_NORMALIZED_ARB, /* DataType */ + 0, /* RedBits */ + 0, /* GreenBits */ + 0, /* BlueBits */ + 0, /* AlphaBits */ + 0, /* LuminanceBits */ + 0, /* IntensityBits */ + 0, /* IndexBits */ + 24, /* DepthBits */ + 8, /* StencilBits */ + 4, /* TexelBytes */ +#if 0 + _mesa_texstore_s8_z24, /* StoreTexImageFunc */ +#else + _mesa_texstore_z24_s8, /* StoreTexImageFunc */ +#endif + NULL, /* FetchTexel1D */ + NULL, /* FetchTexel2D */ + NULL, /* FetchTexel3D */ +#if 0 + fetch_texel_1d_f_s8_z24, /* FetchTexel1Df */ + fetch_texel_2d_f_s8_z24, /* FetchTexel2Df */ + fetch_texel_3d_f_s8_z24, /* FetchTexel3Df */ + store_texel_s8_z24 /* StoreTexel */ +#else + fetch_texel_1d_f_z24_s8, /* FetchTexel1Df */ + fetch_texel_2d_f_z24_s8, /* FetchTexel2Df */ + fetch_texel_3d_f_z24_s8, /* FetchTexel3Df */ + store_texel_z24_s8 /* StoreTexel */ +#endif +}; + const struct gl_texture_format _mesa_texformat_z16 = { MESA_FORMAT_Z16, /* MesaFormat */ GL_DEPTH_COMPONENT, /* BaseFormat */ diff --git a/src/mesa/main/texformat.h b/src/mesa/main/texformat.h index 48f0fe99f27..8f4e2feb483 100644 --- a/src/mesa/main/texformat.h +++ b/src/mesa/main/texformat.h @@ -84,6 +84,7 @@ enum _format { MESA_FORMAT_YCBCR, /* YYYY YYYY UorV UorV */ MESA_FORMAT_YCBCR_REV, /* UorV UorV YYYY YYYY */ MESA_FORMAT_Z24_S8, /* ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ SSSS SSSS */ + MESA_FORMAT_S8_Z24, /* SSSS SSSS ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ */ MESA_FORMAT_Z16, /* ZZZZ ZZZZ ZZZZ ZZZZ */ MESA_FORMAT_Z32, /* ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ ZZZZ */ /*@}*/ @@ -209,6 +210,7 @@ extern const struct gl_texture_format _mesa_texformat_l8; extern const struct gl_texture_format _mesa_texformat_i8; extern const struct gl_texture_format _mesa_texformat_ci8; extern const struct gl_texture_format _mesa_texformat_z24_s8; +extern const struct gl_texture_format _mesa_texformat_s8_z24; extern const struct gl_texture_format _mesa_texformat_z16; extern const struct gl_texture_format _mesa_texformat_z32; /*@}*/ diff --git a/src/mesa/state_tracker/st_format.c b/src/mesa/state_tracker/st_format.c index 17a3cfd5a46..1b9325c159d 100644 --- a/src/mesa/state_tracker/st_format.c +++ b/src/mesa/state_tracker/st_format.c @@ -274,6 +274,8 @@ st_mesa_format_to_pipe_format(GLuint mesaFormat) return PIPE_FORMAT_Z32_UNORM; case MESA_FORMAT_Z24_S8: return PIPE_FORMAT_Z24S8_UNORM; + case MESA_FORMAT_S8_Z24: + return PIPE_FORMAT_S8Z24_UNORM; case MESA_FORMAT_YCBCR: return PIPE_FORMAT_YCBCR; case MESA_FORMAT_RGB_DXT1: @@ -559,10 +561,10 @@ translate_gallium_format_to_mesa_format(enum pipe_format format) return &_mesa_texformat_z16; case PIPE_FORMAT_Z32_UNORM: return &_mesa_texformat_z32; - case PIPE_FORMAT_S8Z24_UNORM: - /* XXX fallthrough OK? */ case PIPE_FORMAT_Z24S8_UNORM: return &_mesa_texformat_z24_s8; + case PIPE_FORMAT_S8Z24_UNORM: + return &_mesa_texformat_s8_z24; case PIPE_FORMAT_YCBCR: return &_mesa_texformat_ycbcr; case PIPE_FORMAT_YCBCR_REV: -- 2.30.2
