* anv/pipeline: make FragCoord include sample positions when sample shadingIago Toral Quiroga2017-03-241-8/+18
| | | | | | | | | | | | | | | | | | | | | | We need to know if sample shading has been requested during shader compilation since that affects the way fragment coordinates are computed. Notice that the semantics of fragment coordinates only depend on whether sample shading has been requested, not on whether more than one sample will actually be produced (that is, minSampleShading and rasterizationSamples do not affect this behavior). Because this setting affects the code we generate for the shader, we also need to include it in the WM prog key. Notice we don't need to alter the OpenGL code because it doesn't ever use this behavior, so they key's value is always false (the default). Fixes: dEQP-VK.glsl.builtin_var.fragcoord_msaa.* Reviewed-by: Jason Ekstrand <[email protected]>
* nir/lower_wpos_center: support adding sample position to fragment coordinateIago Toral Quiroga2017-03-241-1/+1
| | | | | | | | | | | | | According to section 14.6 of the Vulkan specification: "When sample shading is enabled, the x and y components of FragCoord reflect the location of the sample corresponding to the shader invocation." So add a boolean parameter to the lowering pass to select this behavior when we need it. Reviewed-by: Jason Ekstrand <[email protected]>

* anv: Use on-the-fly surface states for dynamic buffer descriptorsJason Ekstrand2017-03-131-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a performance problem with dynamic buffer descriptors. Because we are currently implementing them by pushing an offset into the shader and adding that offset onto the already existing offset for the UBO/SSBO operation, all UBO/SSBO operations on dynamic descriptors are indirect. The back-end compiler implements indirect pull constant loads using what basically amounts to a texelFetch instruction. For pull constant loads with constant offsets, however, we use an oword block read message which goes through the constant cache and reads a whole cache line at a time. Because of these two things, direct pull constant loads are much faster than indirect pull constant loads. Because all loads from dynamically bound buffers are indirect, the user takes a substantial performance penalty when using this "performance" feature. There are two potential solutions I have seen for this problem. The alternate solution is to continue pushing offsets into the shader but wire things up in the back-end compiler so that we use the oword block read messages anyway. The only reason we can do this because we know a priori that the dynamic offsets are uniform and 16-byte aligned. Unfortunately, thanks to the 16-byte alignment requirement of the oword messages, we can't do some general "if the indirect offset is uniform, use an oword message" sort of thing. This solution, however, is recommended for a few of reasons: 1. Surface states are relatively cheap. We've been using on-the-fly surface state setup for some time in GL and it works well. Also, dynamic offsets with on-the-fly surface state should still be cheaper than allocating new descriptor sets every time you want to change a buffer offset which is really the only requirement of the dynamic offsets feature. 2. This requires substantially less compiler plumbing. Not only can we delete the entire apply_dynamic_offsets pass but we can also avoid having to add architecture for passing dynamic offsets to the back- end compiler in such a way that it can continue using oword messages. 3. We get robust buffer access range-checking for free. Because the offset and range are baked into the surface state, we no longer need to pass ranges around and do bounds-checking in the shader. 4. Once we finally get UBO pushing implemented, it will be much easier to handle pushing chunks of dynamic descriptors if the compiler remains blissfully unaware of dynamic descriptors. This commit improves performance of The Talos Principle on ULTRA settings by around 50% and brings it nicely into line with OpenGL performance. Reviewed-by: Lionel Landwerlin <[email protected]>

| | | | | | | | | | | Over the course of driver development, we've come up with a number of different schemes for adding giant blocks of asserts inside the driver. This one is only being used once in anv_pipeline.c and the way it's being used actually generates compiler warnings in release builds.

* anv: Add support for shaderStorageImageWriteWithoutFormatAlex Smith2017-02-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | This allows shaders to write to storage images declared with unknown format if they are decorated with NonReadable ("writeonly" in GLSL). Previously an image view would always use a lowered format for its surface state, however when a shader declares a write-only image, we should use the real format. Since we don't know at view creation time whether it will be used with only write-only images in shaders, create two surface states using both the original format and the lowered format. When emitting the binding table, choose between the states based on whether the image is declared write-only in the shader. Tested on both Sascha Willems' computeshader sample (with the original shaders and ones modified to declare images writeonly and omit their format qualifiers) and on our own shaders for which we need support for this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here brw_setup_vue_interpolation() is rewritten not to use the InterpQualifier array in gl_fragment_program which will allow us to remove it. This change also makes the code which is only used by gen4/5 more self contained as it now has its own gen5_fragment_program struct rather than storing the map in brw_context. This means the interpolation map will only get processed once and will get stored in the in memory cache rather than being processed everytime the fs changes. Also by calling this from the fs compile code rather than from the upload code and using the interpolation assigned there we can get rid of the BRW_NEW_INTERPOLATION_MAP flag. It might not seem ideal to add a gen5_fragment_program struct however by the end of this series we will have gotten rid of all the brw_{shader_stage}_program structs and replaced them with a generic brw_program struct so there will only be two program structs which is better than what we have now. V2: Don't remove BRW_NEW_INTERPOLATION_MAP from dirty_bit_map until the following patch to fix build error. V3 - Suggestions by Jason: - name struct gen4_fragment_program rather than gen5_fragment_program - don't use enum with memset() - create interp mode set helper and simplify logic to call it - add assert when calling function to show prog will never be NULL for gen4/5 i.e. no Vulkan Reviewed-by: Jason Ekstrand <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

* anv: Rework pipeline cachingJason Ekstrand2016-08-301-70/+91
| | | | | | | | | | | | | | | | | | | The original pipeline cache the Kristian wrote was based on a now-false premise that the shaders can be stored in the pipeline cache. The Vulkan 1.0 spec explicitly states that the pipeline cache object is transiant and you are allowed to delete it after using it to create a pipeline with no ill effects. As nice as Kristian's design was, it doesn't jive with the expectation provided by the Vulkan spec. The new pipeline cache uses reference-counted anv_shader_bin objects that are backed by a large state pool. The cache itself is just a hash table mapping keys hashes to anv_shader_bin objects. This has the added advantage of removing one more hand-rolled hash table from mesa.
