* swrast: Use MapRenderbuffer for glReadPixels(GL_DEPTH_COMPONENT) fast-paths.Eric Anholt2011-11-011-68/+63
| | | | | | | | This fixes issues with the code playing fast and loose with types of buffers, and as a bonus avoids the wrappers that were previously used to pull bits out of packed depth/stencil buffers. Reviewed-by: Brian Paul <[email protected]>
* Add MapRenderbuffer implementations for software drivers.Eric Anholt2011-11-011-0/+1
| | | | | | | | | | Mesa core's is generic for things like osmesa. For swrast_dri.so, we have to do Y flipping. The front-buffer path isn't actually tested, though, because both before and after it fails with a BadMatch in XGetImage. Reviewed-by: Brian Paul <[email protected]>

* mesa: add swrast_texture_image::BufferBrian Paul2011-10-234-23/+211
| | | | | | | | | | | | | | | In the past, swrast_texture_image::Data has been overloaded. It could either point to malloc'd memory storing texture data, or it could point to a current mapping of GPU memory. Now, Buffer always points to malloc'd memory (if we're not using GPU memory) and Data always points to mapped memory. The next step would be to rename Data -> Map. This change also involves adding swrast functions for mapping textures and renderbuffers prior to rendering to setup the Data pointer. Plus, corresponding functions to unmap texures and renderbuffers. This is very much like similar code in the dri drivers.
* mesa: move gl_texture_image::Data, RowStride, ImageOffsets to swrastBrian Paul2011-10-236-32/+58
| | | | | | Only swrast and the drivers that fall back to swrast need these fields now. This removes the last of the fields related to software rendering from gl_texture_image.
* swrast: fix float->uint conversion of gl_FragDepthBrian Paul2011-10-191-1/+2
| | | | | | | | | Using IROUND() to convert a float depth value to a 32-bit uint Z value. didn't work (it returns a signed value). Just use a cast instead Fixes piglit fbo-depth-array failure with swrast. Note: this is a candidate for the 7.11 branch.
* swrast: Fix fastpaths for glRead/WritePixels(GL_DEPTH_STENCIL)Chad Versace2011-10-182-0/+4
| | | | | | | | | | | | | | | | | | | In some cases, Intel hardware requires that depth and stencil buffers be separate. To accommodate swrast, i965 resorts to hackery that causes a segfault in the fastpaths of draw_depth_stencil_pixels() and read_depth_stencil_pixels(). The hack is that i965 sets framebuffer->Attachment[BUFFER_DEPTH].Renderbuffer and framebuffer->Attachment[BUFFER_STENCIL].Renderbuffer to a dummy renderbuffer for which the GetRow accessors and friends are null. The real buffers are located at framebuffer->_DepthBuffer and framebuffer->_Stencilbuffer. To fix the segault, this patch skips the fastpath if framebuffer->Attachment[BUFFER_DEPTH].Renderbuffer->GetRow is null. Note: This is a candidate for the 7.11 branch.

* swrast: Remove redundant term in logic expressionChad Versace2011-10-152-2/+0
| | | | | | | | Fix is in {read,draw}_depth_stencil_pixels(). If depthRb == stencilRb, then it is redundant to check depthRb->x *and* stencilRb->x. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* swrast: Fix fastpaths in glRead/WritePixels(GL_DEPTH_STENCIL)Chad Versace2011-10-152-0/+4
| | | | | | | | | | | | | | | | | | | | For glReadPixels, the user supplied pixels have format GL_UNSIGNED_INT_24_8. But, when the depthstencil buffer's format was MESA_FORMAT_S8_Z24, the fastpath read from the buffer without reordering the depth and stencil bits. To fix this, this patch just skips the fastpath when the format is not MESA_FORMAT_Z24_S8. The problem and fix for glWritePixels is analagous. Fixes the Piglit tests below on i965/gen6 and causes no regressions. general/depthstencil-default_fb-drawpixels-24_8 general/depthstencil-default_fb-readpixels-24_8 EXT_packed_depth_stencil/fbo-depthstencil-GL_DEPTH24_STENCIL8-drawpixels-24_8 EXT_packed_depth_stencil/fbo-depthstencil-GL_DEPTH24_STENCIL8-readpixels-24_8 Note: This is a candidate for the stable branches.

| | | | | | | | Commit 617cdcd4c7b1cffb584c829c35bdf9c9bf04627b delayed the texel buffer allocation until texture_combine() is called. But the texel buffer is needed sooner in _swrast_texture_span() at line 649. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=41433
* swrast: When asked to map a slice of a 1D array, give back that slice.Eric Anholt2011-10-031-0/+7
| | | | | | | | | Until now, we've been treating 1D arrays as a single slice, and each array slice is actually just a row of the 2D texture. While swrast still stores them this way, hardware drivers think that 1D arrays have actual separate slices not stored as contiguous rows. Reviewed-by: Brian Paul <[email protected]>
* mesa: Delay s_texcombine.c memory allocation until it's used.Eric Anholt2011-10-012-11/+20
| | | | | | Generally we're using fragment programs in all our drivers, so wasting 4MB for code that's never called is pretty lame. Reduces i965 memory allocation for a short shader program from 21,932,128B to 17,737,816B.
