From 0c17b0b6f089e325de6a3f871c8d799326be4202 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 3 Nov 2016 01:58:03 -0700 Subject: [PATCH] mesa: Add linear ETC2/EAC to the compressed format list with ES3 compat. GL_ARB_ES3_compatibility brings ETC2/EAC formats to desktop GL. The meaning of the GL compressed format list is pretty vague - it's supposed to return formats for "general-purpose usage". (GL 4.2 deprecates the list because of this.) Basically everyone interprets this as "linear RGB/RGBA". ETC2/EAC meets that criteria, so while we shouldn't be required to add it to the list, there's also little harm in doing so, at least on platforms with native support. I doubt anyone is using this list for much anyway, so even on platforms without native support, it's probably not a big deal. Makes the following GL45-CTS.gtf43 tests pass: * GL3Tests.eac_compression_r11.gl_compressed_r11_eac * GL3Tests.eac_compression_rg11.gl_compressed_rg11_eac * GL3Tests.eac_compression_signed_r11.gl_compressed_signed_r11_eac * GL3Tests.eac_compression_signed_rg11.gl_compressed_signed_rg11_eac * GL3Tests.etc2_compression_rgb8.gl_compressed_rgb8_etc2 * GL3Tests.etc2_compression_rgb8_pt_alpha1.gl_compressed_rgb8_pt_alpha1_etc2 * GL3Tests.etc2_compression_rgba8.gl_compressed_rgba8_etc2 Signed-off-by: Kenneth Graunke Reviewed-by: Eduardo Lima Mitev --- src/mesa/main/texcompress.c | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) diff --git a/src/mesa/main/texcompress.c b/src/mesa/main/texcompress.c index 9567c5d..15970a7 100644 --- a/src/mesa/main/texcompress.c +++ b/src/mesa/main/texcompress.c @@ -358,21 +358,27 @@ _mesa_get_compressed_formats(struct gl_context *ctx, GLint *formats) } } - if (_mesa_is_gles3(ctx)) { + if (_mesa_is_gles3(ctx) || ctx->Extensions.ARB_ES3_compatibility) { if (formats) { formats[n++] = GL_COMPRESSED_RGB8_ETC2; - formats[n++] = GL_COMPRESSED_SRGB8_ETC2; formats[n++] = GL_COMPRESSED_RGBA8_ETC2_EAC; - formats[n++] = GL_COMPRESSED_SRGB8_ALPHA8_ETC2_EAC; formats[n++] = GL_COMPRESSED_R11_EAC; formats[n++] = GL_COMPRESSED_RG11_EAC; formats[n++] = GL_COMPRESSED_SIGNED_R11_EAC; formats[n++] = GL_COMPRESSED_SIGNED_RG11_EAC; formats[n++] = GL_COMPRESSED_RGB8_PUNCHTHROUGH_ALPHA1_ETC2; - formats[n++] = GL_COMPRESSED_SRGB8_PUNCHTHROUGH_ALPHA1_ETC2; + } else { + n += 7; } - else { - n += 10; + } + + if (_mesa_is_gles3(ctx)) { + if (formats) { + formats[n++] = GL_COMPRESSED_SRGB8_ETC2; + formats[n++] = GL_COMPRESSED_SRGB8_ALPHA8_ETC2_EAC; + formats[n++] = GL_COMPRESSED_SRGB8_PUNCHTHROUGH_ALPHA1_ETC2; + } else { + n += 3; } } -- 2.7.4
