* mesa: Fix _mesa_unpack_dudv_span_byte assertion.Eric Anholt2011-04-171-1/+2
| | | | | | | It was accepting only GL_DUDV_ATI and not the specific sized format GL_DU8DV8_ATI. Fixes assertion failure at startup in Shadowgrounds. Reviewed-by: Brian Paul <brianp@vmware.com>
* prog_optimize: Add simplify CMP optimization passTom Stellard2011-04-161-0/+78
| | | | | | | This pass coverts CMP T0, T1 T2 T0 -> MOV T0, T2 when the CMP instruction is the first instruction to write to register T0. This pass is useful for hardware that requires a lot of lowering passes that generate many CMP instructions.

| | | | | | | | | | | | This is the same as ARB_draw_buffers (which derived from it), except for s/ARB/ATI/. The glapi bits were already in place, and what was missing was just the ARB_fp part. The new Humble Bundle game "trine" tries to use this extension without checking that it's exposed, which this works around.

| | | | | | | | | | | | | Prior to Gen6, we use the GS for breaking down quads, quad-strips, and line loops. On Gen6, earlier stages already take care of this, so we never need the GS. Since this code is likely completely untested, remove it for now. We can write new code when enabling real geometry shaders.

* Revert "i965: Reinstate max-index paranoia"Chris Wilson2011-04-121-1/+1
| | | | | | | | | | | | | | | | | | This reverts commit b4cbd2b312d53a50603e2cda925711bc9def4517. It looked like a safe sanity check. It missed the issue of the start of the buffer not being at 0, but even that was not enough to explain why setting the max vertex index caused glyphs to be dropped from the game 'Achron'. Instead, the issue appears to be related to the use of the vertex bias and so we would need to re-emit the max-index every time we adjusted the bias, so re-emitting the relocations and defeating the original optimisation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | unorm1616 According to https://bugs.freedesktop.org/show_bug.cgi?id=34280 commit 5d1387b2da3626326410804026f8b92f1a121fdc causes the font corruption problems people have been seeing under various apps and gnome-shell on r200 cards. This commit changed (loosened) the check for using the memcpy path in the former al88 / al1616 texstore functions, which are now also used to store rg texures. This patch restores the old strict check in case of al textures. I've no idea why this fixes things, since I don't know the code in question at all. But after seeing the bisect in bfdo34280 point to this commit, I gave this fix a try and it fixes the font issues seen on r200 cards. [airlied: r200 has no native working A8, so it does an internal storage format of AL88 however srcFormat == internalFormat == ALPHA when we get to this point, so it copies, but it wants to store into an AL88 not ALPHA so fails, I'll also push a piglit test for this on r200].

At the very least, this was missing parenthesis around "alignment - 1". As a result, if value was already aligned, it would be reduced by alignment. Condisder: x = ROUND_DOWN_TO(256, 128); This becomes: x = ALIGN(256 - 128 - 1, 128); Or: x = ALIGN(127, 128); Which becomes: x = 128; This macro is currently only used in brw_state_batch (brw_state_batch.c). It looks like the original version of this macro would just use too much space in the batch buffer. It's possible, but not at all clear to me from the code, that the original behavior is actually desired. In any case, this patch does not cause any piglit regressions on my Ironlake system. I also think that ALIGN_FLOOR would be a better name for this macro, but ROUND_DOWN_TO matches rounddown in the Linux kernel.
