* swrast: add texfetch code for some XBGR formatsBrian Paul2013-06-112-9/+46
| | | | | | | | | | Fixes piglit texture-packed-formats regression. We need to implement more XBGR formats here eventually, but many are UINT/SINT formats which swrast doesn't handle yet anyway (integer textures).

* mesa: Add a _mesa_problem to document a piglit failure on i965.Eric Anholt2013-06-101-0/+6
| | | | | | | | | Having figured out what was going on with piglit fbo-depth copypixels GL_DEPTH_COMPONENT32F (falling all the way back to swrast on CopyPixels to a float depth buffer), I'm not inclined to fix the problem currently but it seems worth saving someone else the debug time.

| | | | | | | | | | Everyone was doing effectively the same thing, except for some funky code reuse in Intel, and swrast mistakenly recomputing _BaseFormat instead of using the texture's _BaseFormat. swrast's sRGB handling is left in place, though it should be done by using _mesa_get_render_format() at render time instead (as-is, it will miss updates to GL_FRAMEBUFFER_SRGB).

* swrast: Always use MapTextureImage for mapping textures for swrast.Eric Anholt2013-04-302-12/+56
| | | | | | | | | | | | | | | Now that everything goes through ImageSlices[], we can rely on the driver's existing texture mapping function. A big block of code goes away on Radeon that looks like it was to deal with the validate that happened at SpanRenderStart, which no longer occurs since we don't need validation for the MapTextureImage hook. v2: Rewrite comment about ImageSlices, fix duplicated swImages, touch up unmap loop.

* swrast: Make a teximage's stored RowStride be in terms of bytes per row.Eric Anholt2013-04-306-9/+30
| | | | | | | | | | | | | For hardware drivers with pitch alignment requirements, a non-power-of-two-sized texture format won't end up being an integer number of pixels per row. Also, avoids having to change our units between MapTextureImage's rowStride and swrast's RowStride. This doesn't fully convert the compressed texel fetch path, but does make sure we don't drop any bits (not that we'd expect to).

| | | | | | | | | | | | | | | | | | | | | This patch fixes a blitting case when drawAttachment->Texture == readAttachment->Texture. It was causing an assertion failure in intel_miptree_attach_map() with gles3 conformance test case: framebuffer_blit_functionality_minifying_blit Number of changes in this file look scary.

Handle a corner case when base code word value is -128. As per OpenGL ES 3.0 specification -128 is not an allowed value and should be truncated to -127. 2. Converting a decoded 16 bit signed data to 16 bit unsigned data by adding 2 ^ 15 gives us an output which matches the decompressed image (.ppm) generated by ericsson's etcpack tool. ericsson is also doing this conversion in their tool because .ppm image files don't support signed data. But gles 3.0 specification doesn't suggest this conversion. We need to keep the decoded data in signed format. Both signed format tests in gles3 conformance pass with these changes.
