* gallium: add texture gather support to gallium (v3)Dave Airlie2014-02-2517-2/+73
| | | | | | | | | | | | | | | | | | | | | 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]>

* gallium/targets: resolve undefined reference to pipe_loader_sw_probe_driEmil Velikov2014-02-243-0/+15
| | | | | | | | | | | | | With the introduction of the pipe_loader_sw_probe_dri helper we require the sw/dri winsys during linking stage despite it being unused by any of the targets.

* pipe-loader: wrap pipe_loader_sw_probe_xlib within HAVE_PIPE_LOADER_XLIBEmil Velikov2014-02-248-7/+41
| | | | | | | | | | | | | | | | | | | The above function implies using the the xlib winsys, which has additional library dependencies that should not be forced. Make the software xlib pipe loader optional thus avoid all the dependency hell.

* i965: Don't try to use the hardware blitter for multisampled miptrees.Kenneth Graunke2014-02-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | The blitter is completely ignorant of MSAA buffer layouts, so any attempt to use BLT paths with MSAA buffers is likely to break spectacularly. In most cases, BLORP handles MSAA blits, so we never hit this bug. Until recently, it also wasn't worth fixing, since Meta couldn't handle MSAA either, so there was nothing to fall back to. But now there is. +143 piglit tests on Broadwell (which doesn't have BLORP support). Surprisingly, three also start failing. Since non-IMS MSAA buffers store samples in successive array slices, using the blitter ought to access sample 0 and ignore the rest, which is apparently good enough for a few not-very-picky Piglit tests. Presumably the meta replacement code is still broken. No Piglit changes on Ivybridge. v2: Move the early return to the top of the function (suggested by Paul).

* freedreno/a3xx/compiler: half-precision outputRob Clark2014-02-236-10/+130
| | | | | | | | | | | | | | | | | | | | Using generic shaders caused a measurable fps drop, which was isolated to use of full precision (vs half precision) output. This is an attempt to regain that lost performance by using half precision solid/blit shaders (when the output format is not float32). Note: for the built-in shaders, I would not expect them to be register starved. And in fact it is the solid frag shader that seems to have the biggest impact. So I suspect you get double the pixel pipe units (or half the cycles) when the output is half precision. So there may be some gain to using half precision output for application shaders as well, even though the rest of register usage is still full precision. But for half precision to work for more complex shaders, we need to deal with some constraints, like cat2 needing same precision for it's two src registers. So for now it is not enabled by default except for the built-in shaders. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx: add shader variantsRob Clark2014-02-2310-196/+283
| | | | | | | | | Start putting in place infrastructure to deal with multiple shader variants. Initially we'll use this for two sided color (frag) and binning pass (vert) shaders. Possibly need for others later (such as YUV vs RGB eglImage?). Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: collapse nop's with repeatRob Clark2014-02-232-0/+15
| | | | | | | | | Easier than making more extensive use of rpt, and the more compact shaders seem to bring some bit of performance boost.
