* gallium: add PIPE_CAP_MAX_VARYINGSKarol Herbst2019-02-071-0/+2
| | | | | | | | | | | | | | | | | Some NVIDIA hardware can accept 128 fragment shader input components, but only have up to 124 varying-interpolated input components. We add a new cap to express this cleanly. For most drivers, this will have the same value as PIPE_SHADER_CAP_MAX_INPUTS for the fragment shader.

* Revert "llvmpipe: Always return some fence in flush (v2)"Roland Scheidegger2019-01-091-2/+0
| | | | | | | | | This reverts commit f6a6da8131383d8eeee07cd59326a70f4b15866b. With this commit we see massive amounts of asserts triggering in lp_fence_wait(), assert(f->issued), for instance with libgl_xlib state tracker and piglit. Not entirely sure if the assert could just be removed.
* llvmpipe: Always return some fence in flush (v2)Tomasz Figa2019-01-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there is no last fence, due to no rendering happening yet, just create a new signaled fence and return it, to match the expectations of the EGL sync fence API. Fixes random "Could not create sync fence 0x3003" assertion failures from Skia on Android, coming from the following code: https://android.googlesource.com/platform/frameworks/base/+/master/libs/hwui/pipeline/skia/SkiaOpenGLPipeline.cpp#427 Reproducible especially with thread count >= 4. One could make the driver always keep the reference to the last fence, but: - the driver seems to explicitly destroy the fence whenever a rendering pass completes and changing that would require a significant functional change to the code. (Specifically, in lp_scene_end_rasterization().) - it still wouldn't solve the problem of an EGL sync fence being created and waited on without any rendering happening at all, which is also likely to happen with Android code pointed to in the commit. Therefore, the simple approach of always creating a fence is taken, similarly to other drivers, such as radeonsi. Tested with piglit llvmpipe suite with no regressions and following tests fixed: egl_khr_fence_sync conformance eglclientwaitsynckhr_flag_sync_flush eglclientwaitsynckhr_nonzero_timeout eglclientwaitsynckhr_zero_timeout eglcreatesynckhr_default_attributes eglgetsyncattribkhr_invalid_attrib eglgetsyncattribkhr_sync_status v2: - remove the useless lp_fence_reference() dance (Nicolai), - explain why creating the dummy fence is the right approach.

* gallivm: don't use pavg.b intrinsic on llvm >= 6.0Roland Scheidegger2018-12-211-42/+49
| | | | | | | | | | | | | | | | | | | | | This intrinsic disppeared with llvm 6.0, using it ends up in segfaults (due to llvm issuing call to NULL address in the jited shaders). Add code doing the same thing as the autoupgrade code in llvm so it can be matched and replaced back with a pavgb. While here, also improve lp_test_format, so it tests both with and without cache (as it was, it tested the cache versions only, whereas cache is actually disabled in llvmpipe, and in any case even with it enabled vertex and geometry shaders wouldn't use it). (Although at least for the unorm8 uncached fetch, the code is still quite different to what llvmpipe is using, since that would use unorm8x16 type, whereas the test code is using unorm8x4 type, hence disabling some intrinsic paths.)

* meson: Add tests to suitesDylan Baker2018-11-201-1/+2
| | | | | | | | | | | | | | | | Meson test has a concepts of suites, which allow tests to be grouped together. This allows for a subtest of tests to be run only (say only the tests for nir). A test can be added to more than one suite, but for the most part I've only added a test to a single suite, though I've added a compiler group that includes nir, glsl, and glcpp tests. To use this you'll need to invoke meson test directly, instead of ninja test (which always runs all targets). it can be invoked as: `meson test -C builddir --suite $suitename` (meson test has addition options that are pretty useful).

* gallium: Add a helper for implementing PIPE_CAP_* default values.Eric Anholt2018-09-041-3/+4
| | | | | | | | | | | | | | | | | | One of the pains of implementing a gallium driver is filling in a million pipe caps you don't know about yet when you're just starting out. One of the pains of working on gallium is copy-and-pasting your new PIPE_CAP into each driver. We can fix both of these by having each driver call into the default helper from their default case, so that both sides can ignore each other until they need to. v2: fix i915g build, revert swr change to avoid breaking scons build (https://travis-ci.org/anholt/mesa/jobs/419739857) v3: Rebase on 3 new gallium caps.

* gallium: Split out PIPE_CAP_TEXTURE_MIRROR_CLAMP_TO_EDGE.Kenneth Graunke2018-08-241-0/+1
| | | | | | | | | | | | | Some hardware can do PIPE_TEX_WRAP_MIRROR_REPEAT but not PIPE_TEX_WRAP_MIRROR_CLAMP and PIPE_TEX_WRAP_MIRROR_CLAMP_TO_BORDER. Drivers for such hardware would like to advertise support for ARB_texture_mirror_clamp_to_edge but not EXT_texture_mirror_clamp. This commit adds a new PIPE_CAP_TEXTURE_MIRROR_CLAMP_TO_EDGE bit, changes the extension enable to be based on that, and enables it in all upstream drivers which supported PIPE_CAP_TEXTURE_MIRROR_CLAMP (so they continue supporting this mode).

* llvmpipe: improve rasterization discard logicRoland Scheidegger2018-05-2315-89/+118
| | | | | | | | | | | | | | | | | | | | | | This unifies the explicit rasterization discard as well as the implicit rasterization disabled logic (which we need for another state tracker), which really should do the exact same thing. We'll now toss out the prims early on in setup with (implicit or explicit) discard, rather than do setup and binning with them, which was entirely pointless. (We should eventually get rid of implicit discard, which should also enable us to discard stuff already in draw, hence draw would be able to skip the pointless clip and fallback stages in this case.) We still need separate logic for only null ps - this is not the same as rasterization discard. But simplify the logic there and don't count primitives simply when there's an empty fs, regardless of depth/stencil tests, which seems perfectly acceptable by d3d10. While here, also fix statistics for primitives if face culling is enabled. No piglit changes. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>

* llvmpipe: Fix random number generation for unit testsRoland Scheidegger2018-05-142-2/+19
| | | | | | | | | | | | | | | | | | | | | | | We were never producing negative numbers for signed types. Also fix only producing half the valid range for uint32, and properly clamp signed values. Because this now also properly tests snorm with actually negative values, need to increase eps for such conversions. I believe these cannot actually be hit in ordinary operation (e.g. if a snorm texture is sampled and output to snorm RT, it will still go through snorm->float and float->snorm conversion), so don't bother to do anything to fix the bad accuracy (might be quite complex). Basically, the issue is for something like snorm16->snorm8 that in the end this will just use a 8 bit arithmetic right shift. But the math behind it says we should actually do a division by 32767 / 127, which is ~258, not 256. So the result can be one bit off (values have too large magnitude), and furthermore, the shift has incorrect rounding (always rounds down). For positive numbers, these errors have different direction, but for negative ones they have the same, hence for some values the error will be 2 bit in the end.

| | | | | | | | | | | | | | The comment said it will only represent the lowest 32 regs. This was not entirely true in practice, since at least on x86 you'll get masked shifts (unless the compiler could recognize it already and toss it out). It turns out this actually works out alright (presumably noone uses it for temp regs) when increasing max sampler views, so make that behavior explicit. Albeit it feels a bit hacky (but in any case, explicit behavior there is better than undefined behavior). Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Brian Paul <[email protected]>
