2014-03-07gallium: allow setting of the internal stream output offsetZack Rusin1-1/+1
D3D10 allows setting of the internal offset of a buffer, which is in general only incremented via actual stream output writes. By allowing setting of the internal offset draw_auto is capable of rendering from buffers which have not been actually streamed out to. Our interface didn't allow. This change functionally shouldn't make any difference to OpenGL where instead of an append_bitmask you just get a real array where -1 means append (like in D3D) and 0 means do not append.

2014-02-25gallium: add texture gather support to gallium (v3)Dave Airlie1-0/+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.

2013-12-13swrast* (gallium, classic): add MESA_copy_sub_buffer support (v3)Dave Airlie1-2/+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.

2013-11-07draw,llvmpipe,util: add depth bias calculation for arb_depth_buffer_floatMatthew McClure1-15/+8
With this patch, the llvmpipe and draw modules will calculate the depth bias according to floating point depth buffer semantics described in the arb_depth_buffer_float specification, when the driver has a z buffer bound with a format type of UTIL_FORMAT_TYPE_FLOAT. By default, the driver will use the existing UNORM calculation for depth bias. A new function, draw_set_zs_format, was added to calculate the Minimum Resolvable Depth value and floating point depth sense for the draw module.

2013-10-12softpipe: fix seamless cube filteringRoland Scheidegger1-48/+151
Fix coord wrapping (and face selection too) in case of edges. Unfortunately, the coord wrapping is way more complicated than what the code did, as it depends on the face and the direction where the texel falls off the face (the logic needed to get this right in fact seems utterly ridiculous). Also fix a bug in (y direction under/overflow) face selection. And get rid of complicated cube corner handling. Just like edge case, the coord wrapping was wrong and it seems very difficult to fix. I'm near certain it can't always work anyway (though ordinary seamless filtering on edge has actually a similar problem but not as severe) because we don't have per-pixel face, hence could have multiple corner texels which would make it very difficult to average the remaining texels correctly. Hence simply pick a texel which would only have fallen off one edge but not both instead, which is not quite accurate but actually I think should be enough to meet OpenGL (but not d3d10) requirements. v2: small fixes suggested by Brian, add some comments.

2013-08-27draw: clean up setting stream out information a bitRoland Scheidegger3-17/+20
In particular noone is interested in the vertex count, so drop that, and also drop the duplicated num_primitives_generated / so.primitives_storage_needed variables in drivers. I am unable for now to figure out if primitives_storage_needed in SO stats (used for d3d10) should increase if SO is disabled, though the equivalent num_primitives_generated used for OpenGL definitely should increase. In any case we were only counting when SO is active both in softpipe and llvmpipe anyway so don't pretend there's an independent num_primitives_generated counter which would count always. (This means the PIPE_QUERY_PRIMITIVES_GENERATED count will still be wrong just as before, should eventually fix this by doing either separate counting for this query or adjust the code so it always counts this even if SO is inactive depending on what's correct for d3d10.)

2013-07-12tgsi: rename the TGSI fragment kill opcodesBrian Paul1-1/+1
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 <jfonseca@vmware.com>
