* mesa/formats: add rest of integer formats.Dave Airlie2011-10-051-0/+46
| | | | | | | | | | | | | | | | This is taken from reading EXT_texture_integer + EXT_texture_rg in combination, Comments on necessity of each format, naming of formats and bugs in the formats tables please. Is there any formats I've missed? Eric looked over this to make sure its consistent at least. As I've changed the ordering of things in the format table, the follow patches are required to avoid regression. Signed-off-by: Dave Airlie <[email protected]>

| | | | | | | | | | | Nothing in Mesa supports color-index textures, and most of the other infrastructure that could allow such support has already been removed. This puts the final nail in the coffin. Also clean out some GL_COLOR_INDEX comments in formats.c. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

* mesa: Fix return type of _mesa_get_format_bytes() (#37351)Adam Jackson2011-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Despite that negative values aren't sensible here, making this unsigned is dangerous. Consider get_pointer_generic, which computes a value of the form: void *base + (int x * int stride + int y) * unsigned bpp The usual arithmetic conversions will coerce the (x*stride + y) subexpression to unsigned. Since stride can be negative, this is disastrous. Fixes at least the following piglit tests on Ironlake: fbo/fbo-blit-d24s8 spec/ARB_depth_texture/fbo-clear-formats spec/EXT_packed_depth_stencil/fbo-clear-formats NOTE: This is a candidate for the 7.10 branch.

* mesa: add EXT_texture_compression_latcMarek Olšák2011-03-081-0/+8
| | | | | | | | | | | | | | | | | The encoding/decoding algorithms are shared with RGTC. Thanks to some magic with the base format, the RGTC texstore functions work for LATC too. swrast passes the related piglit tests besides two things: - The alpha channel is wrong (it's always 1), however the incorrect alpha channel makes some other tests fail too, so I guess it's unrelated to LATC. - Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]), however RGTC has the same problem. Further testing (with other of my patches) shows that hardware drivers and softpipe work. BTW, ETQW uses this extension.

* mesa: Identify packed depth/stencil buffers using the Format field.Nick Bowler2010-08-261-0/+3
| | | | | | | | | | | | | | | | | | | | 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.
