From 0c81739528fd8f240176bb120c90c712f9606718 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Thu, 18 Mar 2010 20:58:04 +0100 Subject: [PATCH] r300g: mark SRGB colorbuffers as unsupported I can't find the register bits for SRGB-aware blending and it's not even exposed by fglrx so it's most probably not supported by hw. --- src/gallium/drivers/r300/r300_texture.c | 21 +-------------------- 1 file changed, 1 insertion(+), 20 deletions(-) diff --git a/src/gallium/drivers/r300/r300_texture.c b/src/gallium/drivers/r300/r300_texture.c index 7c7656068bb..09067aab3bf 100644 --- a/src/gallium/drivers/r300/r300_texture.c +++ b/src/gallium/drivers/r300/r300_texture.c @@ -302,7 +302,6 @@ static uint32_t r300_translate_colorformat(enum pipe_format format) case PIPE_FORMAT_A8_UNORM: case PIPE_FORMAT_I8_UNORM: case PIPE_FORMAT_L8_UNORM: - case PIPE_FORMAT_L8_SRGB: case PIPE_FORMAT_R8_UNORM: case PIPE_FORMAT_R8_SNORM: return R300_COLOR_FORMAT_I8; @@ -317,18 +316,12 @@ static uint32_t r300_translate_colorformat(enum pipe_format format) /* 32-bit buffers. */ case PIPE_FORMAT_B8G8R8A8_UNORM: - case PIPE_FORMAT_B8G8R8A8_SRGB: case PIPE_FORMAT_B8G8R8X8_UNORM: - case PIPE_FORMAT_B8G8R8X8_SRGB: case PIPE_FORMAT_A8R8G8B8_UNORM: - case PIPE_FORMAT_A8R8G8B8_SRGB: case PIPE_FORMAT_X8R8G8B8_UNORM: - case PIPE_FORMAT_X8R8G8B8_SRGB: case PIPE_FORMAT_A8B8G8R8_UNORM: case PIPE_FORMAT_R8G8B8A8_SNORM: - case PIPE_FORMAT_A8B8G8R8_SRGB: case PIPE_FORMAT_X8B8G8R8_UNORM: - case PIPE_FORMAT_X8B8G8R8_SRGB: case PIPE_FORMAT_R8SG8SB8UX8U_NORM: return R300_COLOR_FORMAT_ARGB8888; case PIPE_FORMAT_R10G10B10A2_UNORM: @@ -393,12 +386,7 @@ static uint32_t r300_translate_out_fmt(enum pipe_format format) desc = util_format_description(format); /* Specifies how the shader output is written to the fog unit. */ - if (desc->colorspace == UTIL_FORMAT_COLORSPACE_SRGB) { - /* The gamma correction causes precision loss so we need - * higher precision to maintain reasonable quality. - * It has nothing to do with the colorbuffer format. */ - modifier |= R300_US_OUT_FMT_C4_10_GAMMA; - } else if (desc->channel[0].type == UTIL_FORMAT_TYPE_FLOAT) { + if (desc->channel[0].type == UTIL_FORMAT_TYPE_FLOAT) { if (desc->channel[0].size == 32) { modifier |= R300_US_OUT_FMT_C4_32_FP; } else { @@ -428,7 +416,6 @@ static uint32_t r300_translate_out_fmt(enum pipe_format format) return modifier | R300_C2_SEL_A; case PIPE_FORMAT_I8_UNORM: case PIPE_FORMAT_L8_UNORM: - case PIPE_FORMAT_L8_SRGB: case PIPE_FORMAT_R8_UNORM: case PIPE_FORMAT_R8_SNORM: return modifier | R300_C2_SEL_R; @@ -438,18 +425,14 @@ static uint32_t r300_translate_out_fmt(enum pipe_format format) case PIPE_FORMAT_B5G5R5A1_UNORM: case PIPE_FORMAT_B4G4R4A4_UNORM: case PIPE_FORMAT_B8G8R8A8_UNORM: - case PIPE_FORMAT_B8G8R8A8_SRGB: case PIPE_FORMAT_B8G8R8X8_UNORM: - case PIPE_FORMAT_B8G8R8X8_SRGB: return modifier | R300_C0_SEL_B | R300_C1_SEL_G | R300_C2_SEL_R | R300_C3_SEL_A; /* BGRA 32-bit outputs. */ case PIPE_FORMAT_A8R8G8B8_UNORM: - case PIPE_FORMAT_A8R8G8B8_SRGB: case PIPE_FORMAT_X8R8G8B8_UNORM: - case PIPE_FORMAT_X8R8G8B8_SRGB: return modifier | R300_C0_SEL_A | R300_C1_SEL_R | R300_C2_SEL_G | R300_C3_SEL_B; @@ -457,9 +440,7 @@ static uint32_t r300_translate_out_fmt(enum pipe_format format) /* RGBA 32-bit outputs. */ case PIPE_FORMAT_A8B8G8R8_UNORM: case PIPE_FORMAT_R8G8B8A8_SNORM: - case PIPE_FORMAT_A8B8G8R8_SRGB: case PIPE_FORMAT_X8B8G8R8_UNORM: - case PIPE_FORMAT_X8B8G8R8_SRGB: return modifier | R300_C0_SEL_A | R300_C1_SEL_B | R300_C2_SEL_G | R300_C3_SEL_R; -- 2.30.2
