intel: Fix intel_map_renderbuffer() for depthstencil buffers with separate stencil
For a depthstencil buffer with separate stencil, intel_renderbuffer::region is null. (The regions are kept in hidden depth and stencil buffers). Since the region is null, intel_map_renderbuffer() assumed there was no data and returned a null map pointer, which in turn was dereferenced (!) by MapRenderbuffer's caller. This patch fixes intel_map_renderbuffer() to map the hidden depth buffer through the GTT and return that as the mapped pointer. Also, the stencil bits are scattered and gathered when needed. Fixes the following Piglit tests on gen7: fbo/fbo-readpixels-depth-formats hiz/hiz-depth-read-fbo-d24s8 hiz/hiz-stencil-read-fbo-d24s8 EXT_packed_depth_stencil/fbo-clear-formats EXT_packed_depth_stencil/fbo-depth-GL_DEPTH24_STENCIL8-blit EXT_packed_depth_stencil/fbo-depth-GL_DEPTH24_STENCIL8-drawpixels EXT_packed_depth_stencil/fbo-depth-GL_DEPTH24_STENCIL8-readpixels EXT_packed_depth_stencil/fbo-depthstencil-GL_DEPTH24_STENCIL8-readpixels-24_8 EXT_packed_depth_stencil/fbo-depthstencil-GL_DEPTH24_STENCIL8-readpixels-FLOAT-and-USHORT EXT_packed_depth_stencil/fbo-stencil-GL_DEPTH24_STENCIL8-readpixels Reviewed-by: Eric Anholt <[email protected]> Signed-off-by: Chad Versace <[email protected]>
