* gallium/util: use ui[4] instead of ui in union util_colorRoland Scheidegger2014-04-252-4/+4
| | | | | | | | util_color often merely represents a collection of bytes, however it is inconvenient if those bytes can only be accessed as floats/doubles for int formats exceeding 32bits. (Note that since rgba8 formats use one uint, not 4 bytes, hence the byte and short member were left as is.)

* gallium: add texture gather support to gallium (v3)Dave Airlie2014-02-251-0/+2
| | | | | | | | | | | | | | | | | | | | | This adds support to gallium for a TG4 instruction, and two CAPs. The first CAP is required for GL_ARB_texture_gather. The second CAP is required to expose GL_ARB_gpu_shader5. However so far we haven't found any hardware that natively exposes the textureGatherOffsets feature from GL, so just lower it for now. If hardware appears for this we can add another CAP to allow TG4 to take 4 offsets. v2: add component selection src and a cap to say hw can do it. (st can use to help control GL_ARB_gpu_shader5/GLSL 4.00). Add docs. v3: rename to SM5, add docs. Reviewed-by: Roland Scheidegger <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

| | | | | | | | | | These are components which were originally developed by Tungsten Graphics, which was in turn acquired by VMware, but are de facto now being maintained by third-party contributors of the Mesa open-source community. This matches what's reported by swrast driver and a few other components. Suggested by Ian Romanick.

* swrast* (gallium, classic): add MESA_copy_sub_buffer support (v3)Dave Airlie2013-12-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | This patches add MESA_copy_sub_buffer support to the dri sw loader and then to gallium state tracker, llvmpipe, softpipe and other bits. It reuses the dri1 driver extension interface, and it updates the swrast loader interface for a new putimage which can take a stride. I've tested this with gnome-shell with a cogl hacked to reenable sub copies for llvmpipe and the one piglit test. I could probably split this patch up as well. v2: pass a pipe_box, to reduce the entrypoints, as per Jose's review, add to p_screen doc comments. v3: finish off winsys interfaces, add swrast classic support as well.

* i915g: Implement writemask fixupStéphane Marchesin2013-09-043-38/+90
| | | | | | | | | The fixup code emulates non-BGRA render targets by adding an extra instruction at the end of fragment shaders to swizzle the output. To do this, we also swizzle the blend function. However an oversight until now was that the writemask wasn't getting swizzled. This patch fixes that which fixes a bunch of piglit tests.

* i915g: Add more optimizationsStéphane Marchesin2013-09-043-58/+371
| | | | | | | | | This patch adds liveness analysis to i915g and a couple optimizations which benefit from it. One interesting optimization turns (fake) indirect texture accesses into direct texture accesses (the i915 supports a maximum of 4 indirect texture accesses). Among other things this fixes a bunch of piglit tests.
* draw: inject frontface info into wireframe outputsZack Rusin2013-08-021-0/+2
| | | | | | | | | | | | | | Draw module can decompose primitives into wireframe models, which is a fancy word for 'lines', unfortunately that decomposition means that we weren't able to preserve the original front-face info which could be derived from the original primitives (lines don't have a 'face'). To fix it allow draw module to inject a fake face semantic into outputs from which the backends can figure out the original frontfacing info of the primitives.

* tgsi: rename the TGSI fragment kill opcodesBrian Paul2013-07-122-7/+5
| | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_KIL and KILP had confusing names. The former was conditional kill (if any src component < 0). The later was unconditional kill. At one time KILP was supposed to work with NV-style condition codes/predicates but we never had that in TGSI. This patch renames both opcodes: TGSI_OPCODE_KIL -> KILL_IF (kill if src.xyzw < 0) TGSI_OPCODE_KILP -> KILL (unconditional kill) Note: I didn't just transpose the opcode names to help ensure that I didn't miss updating any code anywhere. I believe I've updated all the relevant code and comments but I'm not 100% sure that some drivers had this right in the first place. For example, the radeon driver might have llvm.AMDGPU.kill and llvm.AMDGPU.kilp mixed up. Driver authors should review their code. Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | | | | | Pass in the size of the index buffer, when available, and use it to handle out of bounds conditions. The behavior in the case of an overflow needs to be the same as with other overflows in the vertex processing pipeline meaning that a vertex should still be generated but all attributes in it set to zero.

| | | | | | | | | | | | | | We would crash when stride was bigger than the size of the buffer. The correct behavior is to just fetch zero's in this case. Unfortunatly with user_buffer's there's no way to validate the size because currently we're just not getting it. Adjust the draw interface to pass the size along the mapped buffer, which works perfectly for buffer backed vertex_buffers and, in future, it will allow us to plumb user_buffer sizes through the same interface.

* i915: Use Y tiling for texturesStéphane Marchesin2013-05-081-2/+7
| | | | | | | | | | | This basically reverts commit 2acc7193743199701f8f6d1877a59ece0ec4fa5b. With the previous change, we're not batchbuffer limited any longer. So we actually start seeing a performance difference between X and Y tiling. X tiling is funny because it is faster for screen-aligned quads but slower in games. So let's use Y tiling which is 10% faster overall.
* i915g: Optimize batchbuffer sizesStéphane Marchesin2013-05-081-3/+5
| | | | | | | Now that we don't throttle at every batchbuffer, we can shrink the size of batchbuffers to achieve early flushing. This gives a significant speed boost in a lot of games (on the order of 20%).

| | | | | | | | | | | | This is the only sane solution for nv50 and nvc0 (really, trust me), but since on other hardware the border colour is tightly coupled with texture state they'd have to undo the swizzle, so I've added a cap.
