* gallium: add red-alpha texture formats and a couple of util functionsMarek Olšák2013-02-131-0/+12
| | | | | | | | | This is for glGetTexImage and it will be used for samplers only (which some drivers already implement by reading util_format_description). v2: incorporate Brian's suggestion Reviewed-by: Brian Paul <[email protected]>

* gallium: add SQRT shader opcodeBrian Paul2013-02-042-2/+3
| | | | | | | | | | | | | | | | | | The glsl-to-tgsi translater will emit SQRT to implement GLSL's sqrt() and distance() functions if the PIPE_SHADER_CAP_TGSI_SQRT_SUPPORTED query says it's supported by the driver. Otherwise, sqrt(x) is implemented with x*rsq(x). The problem with this is sqrt(0) must be handled specially because rsq(0) might be Inf/NaN/undefined (and then 0*rsq(0) is Inf/Nan/undefined). In the glsl-to-tgsi code we use an extra CMP to check if x is zero and then replace the result of x*rsq(x) with zero. In the end, this makes sqrt() generate much more reasonable code for drivers that can do square roots. Note that many of piglit's generated shader tests use the GLSL distance() function.

* gallium: extend pipe_context::flush for it to accept an END_OF_FRAME flagMarek Olšák2013-01-043-2/+11
| | | | | | | | | | | | | | | | | Usage with pipe_context: pipe->flush(pipe, NULL, PIPE_FLUSH_END_OF_FRAME); Usage with st_context_iface: st->flush(st, ST_FLUSH_END_OF_FRAME, NULL); The flag is only a hint for drivers. Radeon will use it for buffer eviction heuristics in the kernel (e.g. for queries like how many frames have passed since a buffer was used). The flag is currently only generated by st/dri on SwapBuffers. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Stéphane Marchesin <[email protected]>

| | | | | | | | | | | | | | | | This just adds the texture target and capability along with 3 new opcodes required to support this extension. As this extension requires some texture opcodes with samp + 5 args, we need to use another src register, this is only required for TEX, TXL and TXB opcodes to implement this spec. TEX2 is required for shadow cube map arrays TXL2 is required for cube map array sampler + explicit lod TXB2 is required for cube map array sampler + lod bias Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

* gallium: add start_slot parameter to set_vertex_buffersMarek Olšák2012-10-311-0/+1
| | | | | | | | | | | | | | | | | | | | | This allows updating only a subrange of buffer bindings. set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that range. Binding NULL resources unbinds buffers too (both buffer and user_buffer must be NULL). The meta ops are adapted to only save, change, and restore the single slot they use. The cso_context can save and restore only one vertex buffer slot. The clients can query which one it is using cso_get_aux_vertex_buffer_slot. It's currently set to 0. (the Draw module breaks if it's set to non-zero) It should decrease the CPU overhead when using a lot of meta ops, but the drivers must be able to treat each vertex buffer slot as a separate state (only r600g does so at the moment). I can imagine this also being useful for optimizing some OpenGL use cases. Reviewed-by: Brian Paul <[email protected]>
* mesa: bump MAX_VARYING to 32Marek Olšák2012-10-291-2/+2
| | | | | | | | | | | | | | | | | We're starting to get apps utilizing more than 16 varyings and most current hardware supports 32 anyway. Tested with r600g. swrast, softpipe and llvmpipe still advertise 16 varyings. This fixes a WebGL crash after launching this demo: https://developer.mozilla.org/en-US/demos/detail/falling-cubes Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=54402 NOTE: This is a candidate for the stable branches.

If transfer_map fails, the pointer to the transfer object remains unchanged (i.e. doesn't have to be NULL). Acked-by: Brian Paul <[email protected]>

* gallium: remove PIPE_MAX_VERTEX/GEOMETRY_SAMPLERS #defineBrian Paul2012-08-161-2/+0
| | | | | | | | | | | | PIPE_MAX_SAMPLERS, PIPE_MAX_VERTEX_SAMPLERS and PIPE_MAX_GEOMETRY_SAMPLERS were all defined to the same value (16). In various places we're creating arrays such as sampler_views[PIPE_SHADER_TYPES][PIPE_MAX_SAMPLERS] so we were assuming the same number of max samplers for all shader stages anyway. Of course, drivers are still free to advertise different numbers of max samplers for different shaders.
* gallium: add TGSI support for multisample texturesMarek Olšák2012-08-151-2/+5
| | | | | | | | | | The only allowed instructions are TXQ_LZ and TXF. TXQ_LZ is like TXQ, but without the LOD parameter (which is always zero with MSAA textures) The 3rd or the 4th texcoord component in TXF should contain the sample index for a 2D_MSAA or 2D_ARRAY_MSAA texture, respectively.

| | | | | | | | | | | This reverts commit 5d5af7d359e0060fa00b90a8f04900b96f9058b0. It turns out the issue this was supposed to fix merely counter-acted a bug in the hardware driver that I wasn't aware of. The resource_resolve is not supposed to do sRGB conversion, period. (This would violate the requirement that source and destination must be of the same format).

| | | | | | | | | | | The format member of pipe_surface may differ from that of the pipe_resource, which is used to communicate, for instance, whether sRGB encode should be enabled in the resolve operation or not.
