* intel: Remove the last spans code!Eric Anholt2013-04-3011-148/+6

* intel: Ensure renderbuffers are current when mapping them.Eric Anholt2013-04-301-6/+1
| | | | | | | | | | | | In the case of renering to windows in X, we would render to stale buffers (or not render at all!) if you hit a MapRenderbuffer as the first thing done to your window after new buffers are ready to be collected in DRI2.

* swrast: Always use MapTextureImage for mapping textures for swrast.Eric Anholt2013-04-3011-300/+64
| | | | | | | | | | | | | | | Now that everything goes through ImageSlices[], we can rely on the driver's existing texture mapping function. A big block of code goes away on Radeon that looks like it was to deal with the validate that happened at SpanRenderStart, which no longer occurs since we don't need validation for the MapTextureImage hook. v2: Rewrite comment about ImageSlices, fix duplicated swImages, touch up unmap loop.

* nouveau: Replace swrast_texture_image->Map usage with ->Buffer.Eric Anholt2013-04-301-3/+1
| | | | | | | | This code is trying to deal with providing a map in the case that AllocTexImageBuffer was called, which is hooked up to the swrast variant. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* nouveau: Just use MapTextureImage instead of duplicating the logic.Eric Anholt2013-04-301-81/+18

* swrast: Make a teximage's stored RowStride be in terms of bytes per row.Eric Anholt2013-04-306-9/+30
| | | | | | | | | | | | | For hardware drivers with pitch alignment requirements, a non-power-of-two-sized texture format won't end up being an integer number of pixels per row. Also, avoids having to change our units between MapTextureImage's rowStride and swrast's RowStride. This doesn't fully convert the compressed texel fetch path, but does make sure we don't drop any bits (not that we'd expect to).

* swrast: Replace ImageOffsets with an ImageSlices pointer.Eric Anholt2013-04-3013-185/+123
| | | | | | | | | | | | | This is a step toward allowing drivers to use their normal mapping paths, instead of requiring that all slice mappings come from an aligned offset from the first slice's map.

| | | | | | | | | | | | | | It appears that Z16 on Intel hardware is in fact slower than Z24, so people are getting surprisingly hurt when trying to use Z16 as a performance-versus-precision tradeoff, or when they're targeting GLES2 and that's all you get. GL 3.0+ have Z16 on the list of required exact format sizes, but GLES doesn't, so choose the better-performing layout in that case.

* mesa: Fix error checking for getters consisting of only API versions.Eric Anholt2013-04-291-32/+24
| | | | | | | | | In almost all of our cases, getters that are turned on for only some API variants will have an extension listed as one of the things that can enable it, and thus api_check gets set. For extra_gl30_es3 (used for NUM_EXTENSIONS, MAJOR_VERSION, MINOR_VERSION) on a GL 2.1 context, though, we would check twice, not find either one, but never actually throw the error.

* i915: Correctly set the OQ counter bits.Eric Anholt2013-04-292-0/+2
| | | | | | | | | | | | While we may provide the extension, we need to tell applications that they can't actually use it: An implementation can either set QUERY_COUNTER_BITS_ARB to the value 0, or to some number greater than or equal to n. If an implementation returns 0 for QUERY_COUNTER_BITS_ARB, then the occlusion queries will always return that zero samples passed the occlusion test, and so an application should not use occlusion queries on that implementation.
* i965: Move is_math/is_tex/is_control_flow() to backend_instruction.Kenneth Graunke2013-04-296-76/+49
| | | | | | | | | | | | | | | These are entirely based on the opcode, which is available in backend_instruction. It makes sense to only implement them in one place. This changes the VS implementation of is_tex() slightly, which now accepts FS_OPCODE_TXB and SHADER_OPCODE_LOD. However, since those aren't generated in the VS anyway, it should be fine. This also makes is_control_flow() available in the VS. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | | | | | | | | | | Interpolation modes other than perspective-barycentric-pixel-center (and their associated coefficients in the WM payload) only exist in Gen6 and later. Unfortunately, if a varying was declared as `centroid`, we would blindly read the nonexistant values, and so produce all manner of bad behavior -- texture swimming, snow, etc. Fixes rendering in Counter-Strike Source and Team Fortress 2 on Ironlake.

* i965/vs: Add a function to fix-up uniform arguments for 3-src insts.Matt Turner2013-04-252-0/+25
| | | | | | | | | | | | | | | | | Three-source instructions have a vertical stride overloaded to 4, which prevents directly using vec4 uniforms as arguments. Instead we need to insert a MOV instruction to do the replication for the three-source instruction. With this in place, we can use three-source instructions in the vertex shader. While some thought needs to go into deciding whether its better to use a three-source instruction rather than a sequence of equivalent instructions (when one or more sources are uniforms or immediates), this will allow us to skip a lot of ugly lowering code and use the BFE and BFI2 instructions directly.

| | | | | | | | | | | | | | | | | | Unlike GEN6, the bits of entry count are distributed like this width = (entry_count & 0x0000007f); /* bits [6:0] */ height = (entry_count & 0x001fff80) >> 7; /* bits [20:7] */ depth = (entry_count & 0x7fe00000) >> 21; /* bits [30:21] */ The maximum entry count is still limited to 2^27.
