* mesa/main: consider multisampling enabled when number of samples == 1Nicolai Hähnle2016-11-181-1/+1
| | | | | | | | | | | | | | | There are some differences between how non-multisampled framebuffers (i.e. samples == 0) and multisampled framebuffers with a single sample should be treated. For example, alpha to coverage and writing to gl_SampleMask has an effect with single-sample multisample framebuffers, but not on non-multisample framebuffers. This fixes GL45-CTS.sample_variables.mask.*.samples_1.* at least for Gallium drivers (and possibly others, though at least radeonsi needs an additional fix).

* mesa: fix empty program log lengthTapani Pälli2016-11-182-3/+6
| | | | | | | | | | | | | | | | | | | In case we have empty log (""), we should return 0. This fixes Khronos WebGL conformance test 'program-infolog'. From OpenGL ES 3.1 (and OpenGL 4.5 Core) spec: "If pname is INFO_LOG_LENGTH , the length of the info log, including a null terminator, is returned. If there is no info log, zero is returned." v2: apply same fix for get_shaderiv and _mesa_GetProgramPipelineiv (Ian) Signed-off-by: Tapani Pälli <[email protected]> Reviewed-by: Iago Toral Quiroga <[email protected]> (v1) Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Nicolai Hähnle <[email protected]> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97321 Cc: "13.0" <[email protected]>
* draw: finally optimize bool clip mask generationRoland Scheidegger2016-11-183-23/+26
| | | | | | | | | | | lp_build_any_true_range is just what we need, though it will only produce optimal code with sse41 (ptest + set) - but even without it on 64bit x86 the code is still better (1 unpack, 2 movq + or + set), on 32bit x86 it's going to be roughly the same as before. While here also make it a "real" 8bit boolean - cuts one instruction but more importantly similar to ordinary booleans. Reviewed-by: Jose Fonseca <[email protected]>
* draw: use vectorized calculations for fetch (v2)Roland Scheidegger2016-11-181-131/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of doing all the math with scalars, use vectors. This means the overflow math needs to be done manually, albeit that's only really problematic for the stride/index mul, the rest has been pretty much moved outside the shader loop (albeit the mul could actually be optimized away too), where things are still scalar. To eliminate control flow in the main shader loop fetch, provide fake buffers (so index 0 is always valid to fetch). Still uses aos fetch though in the end - mostly because some more code would be needed to handle unaligned fetches in that path, and because for most formats it won't make a difference anyway (we generate some truly horrendous code for things like R16G16_something for instance). Instanced fetch however stays roughly the same as before, except that no longer the same element is fetched multiple times (I've seen a reduction of ~3 times in main shader loop size due to llvm not recognizing it's all the same fetch, since it would have been possible some of the fetches getting replaced with zeros in case vector size exceeds remaining fetch count - the values of such fetches don't matter at all though). Also, for elts gathering, use vectorized code as well. The generated shaders are smaller and faster to compile (not entirely sure about execution speed, but generally unless there's just single vertices to handle I would expect it to be faster - there's more opportunities for future improvements by using soa fetch). v3: skip the fake index buffer, not needed due to the jit code never seeing the real index buffer in the first place. Fix a bug with mask expansion (needs SExt, not ZExt). Also, be really really careful to keep the behavior the same, even in cases where it looks wrong, and add comments why the code is doing the seemingly wrong stuff... Fortunately it's not actually more complex in the end... Also change function order slightly just to make the diff more readable. No piglit change. Passes some internal testing with another api too... Reviewed-by: Jose Fonseca <[email protected]>

* mesa: Drop PATH_MAX usage.Kenneth Graunke2016-11-172-34/+15
| | | | | | | | | | | | | | | | | | | | | | | | GNU/Hurd does not define PATH_MAX since it doesn't have such arbitrary limitation, so this failed to compile. Apparently glibc does not enforce PATH_MAX restrictions anyway, so it's kind of a hoax: https://www.gnu.org/software/libc/manual/html_node/Limits-for-Files.html MSVC uses a different name (_MAX_PATH) as well, which is annoying. We don't really need it. We can simply asprintf() the filenames. If the filename exceeds an OS path limit, presumably fopen() will fail, and we already check that. (We actually use ralloc_asprintf because Mesa provides that everywhere, and it doesn't look like we've provided an implementation of GNU's asprintf() for all platforms.) Fixes the build on GNU/Hurd.

* anv: Enable "permanent" compression for immutable format imagesJason Ekstrand2016-11-172-1/+26
| | | | | | | | | | | This commit extends our support of color compression to surfaces without the VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT set. These images will never have an image view created with a different format then the one set at image creation time so it's safe to always use compression. We still bail if the image is used as a storage image because that sometimes ends up using a different format. Reviewed-by: Topi Pohjolainen <[email protected]>

| | | | | | | | | This commit moves the handling of resolves into blorp_surf_for_miptree(). Instead of each helper doing resolves and checks itself, it simply tells blorp_surf_for_miptree which aux modes are supported by the given blorp operation and blorp_surf_for_miptree will resolve as-needed.

* anv/image: Add an aux_usage field for "default" auxJason Ekstrand2016-11-174-19/+45
| | | | | | | Initially, the field is set to ISL_AUX_USAGE_NONE so this commit shouldn't bring any functional changes. Setting this field to something else will cause all sampled and storage image views to be created with AUX and blorp will start trying to respect it so set with care.

| | | | | | | This commit adds basic support for color compression. For the moment, color compression is only enabled within a render pass and a full resolve is done before the render pass finishes. All texturing operations still happen with CCS disabled.
