* mesa: add common format-independent memcpy-based ReadPixels pathMarek Olšák2013-03-231-2/+2
| | | | | | | | | | | I'll need the _mesa_readpixels_needs_slow_path function for the blit-based version, but it's also useful to have this memcpy-based path in one place and not scattered across several functions. v2: add "const" to function parameters Reviewed-by: Brian Paul <[email protected]> Tested-by: Brian Paul <[email protected]>
* mesa: Drop manual checks for outside begin/end.Eric Anholt2013-01-211-1/+1
| | | | | | | | | | | We now have a separate dispatch table for begin/end that prevent these functions from being entered during that time. The ASSERT_OUTSIDE_BEGIN_END_WITH_RETVALs are left because I don't want to change any return values or introduce new error-only stubs at this point.

* mesa: Make more consistent use of _mesa_is_{user,winsys}_fbo()Paul Berry2012-07-261-3/+3
| | | | | | | | | | A lot of code was still differentiating between between winsys and user fbos by testing the fbo's name against zero. This converts everything in core mesa, the state tracker, and src/mesa/program over to use _mesa_is_user_fbo() and _mesa_is_winsys_fbo().

* msaa: Compute visual samples/sampleBuffers from all buffers.Paul Berry2012-07-241-2/+7
| | | | | | | | | This patch ensures that Visual.samples and Visual.sampleBuffers are set correctly even in the case where there is no color buffer. Previously, these values would retain their default value of 0 in this circumstance, even if the depth or stencil buffer was multisampled. Reviewed-by: Chad Versace <[email protected]>

| | | | | | | | | | | This just adds the correct checks and asserts in the right places. This doesn't fix all the tests that I've sent to piglit, need to add int paths to go alongside the uint paths that don't go via float to fix it up properly.

* mesa: Identify packed depth/stencil buffers using the Format field.Nick Bowler2010-08-261-2/+2
| | | | | | | | | | | | | | | | | | | | Intel sometimes uses packed depth/stencil buffers even when only a depth buffer or only a stencil buffer was requested. Common code currently uses the _BaseFormat field to determine whether a depth/stencil wrapper is necessary. But unless the user explicitly requested a packed depth/stencil buffer, the _BaseFormat field does not encode this information, and the required wrappers are not created. The problem was introduced by commit 45e76d2665b38b ("mesa: remove a bunch of gl_renderbuffer fields"), which killed off the _ActualFormat field upon which the decision to create a wrapper used to be made. This patch changes the logic to use the Format field instead, which is more like the old code. Fixes fdo bug 27590.

* mesa: Move OES_read_format support from drivers into the core.Eric Anholt2009-12-091-0/+26
| | | | | | | | | | | The assertion is that the correct read type to be using is the native type of the underlying read renderbuffer. For some fallback paths, this may be worse than GL_RGBA/GL_UNSIGNED_BYTE for reads today, but it gets all drivers the expected GL_BGRA/GL_UNSIGNED_BYTE for ARGB8888 or GL_BGR//GL_UNSIGNED_SHORT_5_6_5_REV for rgb565 with no work. This fixes the intel (and other) DRI drivers to report read formats that should hit blit PBO readpixels paths.
