* i965/gen9: Enable lossless compressionTopi Pohjolainen2016-05-121-3/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I tried first creating the auxiliary buffer the same time with the color buffer. That, however, led me into a situation where we would later create the rest of the mip-levels and the compression would need to be disabled (it is only supported for single level buffers). Here we try to create it on demand just before the hardware starts to render. This is similar what we do with fast clear buffers, their creation is deferred until the first clear. This setup also gives the opportunity to detect if the miptree represents the temporaty texture used internally in the mesa core. This texture is mostly written by cpu and therefore enabling compression for it doesn't make much sense. Note that a heuristic is included. Floating point formats are not enabled yet as they are only seen to hurt performance.

| | | | | | | | | | | | | | | | | | | | Until now mcs was associated to single sampled buffers only for fast clear purposes and it was therefore the responsibility of the clear logic to allocate the aux buffer when needed. Now that normal 3D render or blorp blit may render with mcs enabled also, they need to prepare the mcs just as well. v2: Do not enable for scanout buffers v3 (Ben): - Fix typo in commit message. - Check for gen < 9 and return early in brw_predraw_set_aux_buffers() - Check for gen < 9 and return early in intel_miptree_prepare_mcs() v4: Check for msaa_layput and number of samples to determine if lossless compression is to used.

* i965/blorp: Do not skip fast color clear with new colorTopi Pohjolainen2016-05-123-4/+17
| | | | | | | | | | | | | | | | | | | | | | | This hasn't been visible before. It showed up with lossless compression with: dEQP-GLES3.functional.fbo.color.repeated_clear.sample.tex2d.rgb8 Current fast clear logic kicks color resolves even for gpu sampling. In the test case this results into trashing of the fast color clear state between two subsequent clears, and therefore each clear is performed correctly. With lossless compression the resolves are unnecessary and therefore the clear state indicates that the buffer is already cleared. Without considering if the previous color value was the same as the new, clears that need to be performed are skipped and the buffer ends up holding old pixel values. v2 (Ken): Fix the comparison for gen < 9 Signed-off-by: Topi Pohjolainen <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ben Widawsky <[email protected]>
* i965: Enable scalar GS by default.Kenneth Graunke2016-05-121-1/+1
| | | | | | | | | | | | | | | | | I'd originally left this off because Orbital Explorer was hanging the GPU, but it seems to be working these days. There have been a bunch of changes since then, so we probably fixed something. On my Broadwell laptop, both Synmark/GSCloth and Orbital Explorer seem to run at approximately the same framerate in either mode. This is despite large reductions in instruction count for Synmark, and large increases for Orbital Explorer. It apparently just doesn't matter. Switching to scalar mode will gain us fp64 support in the next release, as vec4-mode support isn't yet ready.

* nvc0: fix gl_SampleMaskIn computationIlia Mirkin2016-05-1110-5/+94
| | | | | | | | | | | | | | | | | | | | | The SAMPLEMASK semantic should only return the bits set covered by the current invocation. However we were always retrieving the covmask, which returns the covered samples of the whole pixel. When not doing per-sample invocation, this is precisely what we want. However when doing per-sample invocation, we have to select the sampleid'th bit and only return that. Furthermore, this means that we have to have a 1:1 correlation for invocations and samples. This fixes most dEQP-GLES31.functional.shaders.sample_variables.sample_mask_in.* tests. A few failures remain due to disagreements about nr_samples==1 logic as well as what happens with MSAA x2 RTs when the shading fraction is 0.5. Signed-off-by: Ilia Mirkin <[email protected]>

* i965: Stop splitting fma() prior to optimizationJason Ekstrand2016-05-111-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | According to the GLSL spec, if the user uses the fma() intrinsic to generate a precise-consumed value, and you have it in your hardware, you shouldn't split it. For a while now, we've been splitting all ffma's up-front and then planned to fuse them later which isn't valid. Correctly handling the GLSL behaviour fixes rendering corruptions in Tomb Raider. The only reason why doing this possibly helped before was for ARB programs which is handled by the previous commit. Shader-db results on Haswell: total instructions in shared programs: 7560300 -> 7561510 (0.02%) instructions in affected programs: 56265 -> 57475 (2.15%) helped: 86 HURT: 291 The only shaders in the database that are affected are from "Shadow of Mordor" which is the first app in our database to use fma(). We could, at some point in the future, split inexact ffma opcodes which would fix the shader-db regressions since Shadow of Mordor doesn't ues precise. However, this fixes a bug now and and the shader-db impact is fairly small.

| | | | | | | | | | | | | | | | | | | | | Currently, when cross validating global variables, all global variables seen in the shaders that are part of a program are saved in a table. When checking a variable this already exist in the table, we check both are initialized to the same value. If the already saved variable does not have an initializer, we copy it from the new variable. Unfortunately this is wrong, as we are modifying something it is constant. Also, if this modified variable is used in another program, it will keep the initializer, when it should have none. Instead of copying the initializer, this commit replaces the old variable with the new one. So if we see again the same variable with an initializer, we can compare if both are the same or not. v2: convert tabs in whitespaces (Kenenth Graunke) Reviewed-by: Kenneth Graunke <[email protected]>
