James Dong 1d5aaa6c 2019-08-06T11:20:13 Vulkan: support dynamic indices in array of arrays Expands existing struct-sampler rewrite to flatten arrays of arrays. This allows us to support dynamically-uniform array indexing, which is core in ES 3.2. Samplers inside (possibly nested) structs are broken apart as before, and then if the type resulting from merging the array sizes of the field and its containing structs is an array of array, the array is flattened. Also adds an offset parameter to functions taking in arrays to account for this translation. As a result of outer array sizes leaking into function signatures, functions taking arrays of different sizes are duplicated according to how the function is invoked.

The value of ma was retrieved as the helper invocations would otherwise have a different value as the major axis. This change makes the helpers rechoose ma based on the layer, which removes a number of subgroup operations. This is also more precise as the major axis value could be slightly different from the neighbor.

Shahbaz Youssefi 93560ef5 2019-07-25T16:13:02 Vulkan: Seamful cube map emulation In GLSL, a cube texture is sampled with one of textureCube* functions. This function takes a 3D coordinate which is a vector from the center of the cube and identifies a direction to sample from. GLES2.0 has the following table that translates this 3D coordinate (Rx, Ry, Rz) to a face and ST coordinates within that face. This table can be found in Section 3.7.5 (Cube Map Texture Selection). A compiler pass is implemented in ANGLE that replaces samplerCube declarations with a sampler2DArray. The textureCube* functions are replaced with the corresponding texture* functions with the translated coordinates according to that table. Gradients provided to textureCubeGrad are translated using the same formulae, which is not precise but the spec specifies this projection to be implementation dependent. Helper invocations enabled through WQM (whole quad mode) cause a nuisance in that the extrapolated varyings used as coordinates in a textureCube call could have a different major axis (and therefore face) from the non-helper invocations that lie within the geometry. subgroupQuadSwap* operations are used in conjunction with gl_HelperInvocation to make sure the helper threads calculate texture UVs in the same face as the non-helper invocations.

They are emulated with Vulkan storage buffers, which do have restrictions. The storage buffers are bound at aligned offsets, and the remaining offsets are passed to the shader as uniform values. This means that the driver uniforms are now also bound to the compute pipeline.

Shahbaz Youssefi c13ca2af 2019-07-17T15:46:29 Vulkan: Allow more than one atomic counter buffer binding dEQP assumes there are more than one atomic counter buffers available. This is technically not a requirement by the standard, but nevertheless could be what applications expect as well. This change adds support for multiple atomic counter buffer bindings. This is done by declaring an array of storage buffers for the atomic counter buffers (instead of declaring only one) and passing the (binding, offset) pair around to functions instead of just the offset. The atomic counter is found by indexing `binding` into the storage buffer array first before indexing `offset` into its `uint[]`. ProgramVk's default uniform collection is also fixed not to include atomic counter uniforms. A remaining issue is that atomic counter buffer offsets don't have alignment requirements in GLES, but Vulkan does for storage buffers. Similar to emulated transform feedback buffer offsets, these should be sent to the shader through uniform values. This will be done in a follow up change.

A single atomic counter buffer binding per pipeline is supported. All the atomic counters identify an offset within this buffer. The shader is modified to include a storage buffer definition with `uint counters[];` as the only field. A compiler pass replaces atomic counter definitions with variables that hold the corresponding offset parameter, as well as changing atomic_uint types to just uint (as the offset). Where an atomic counter variable is used, it is replaced with the offset variable (plus the array index, if array). At the same time, built-in `atomicCounter*` functions are replaced with a corresponding `atomic*` function and `memoryBarrierAtomicCounter` is replaced with `memoryBarrierBuffer`.

In this patch we enable support for atomic function returns outside of assignments (e.g. part of arithmetic operations or to index into arrays) and when used directly initialize a variable. Note that we are still missing the functionality to be tag loops with [allow_uav_condition] as required by InterlockedCompareExchange.

Qin Jiajia a735ee2f 2018-05-18T13:29:09 ES31: Support shader storage block in D3D11 compiler - Part1 This patch is the first step to implement a basic skeleton to translate shader storage block to HLSL RWByteAddressBuffer. In GLSL each shader storage block is just one structured block and in API side it corresponds to a buffer range where stores the whole structure. RWStructuredBuffer is an array-like object and can have many structured elements. The structured element doesn't support unsized array and also have a small limitation on the element size. So we choose RWByteAddressBuffer as the counterpart of shader storage block in HLSL. Due to RWByteAddressBuffer does not support using an index to reference a specific location, we must use Load and Store to process the read/write operation of a buffer variable. Moreover, in the compiler tree, since we can't use variable name to get the resource value in RWByteAddressBuffer, we have to calculate the offset of buffer variable in a shader storage block, then call the corresponding wrapper function to get the right value. In this patch, we only process below situations: assign_to_ssbo := ssbo_access_chain = expr_no_ssbo; assign_from_ssbo := lvalue_no_ssbo = ssbo_access_chain; The translation is like below: // GLSL #version 310 es layout(local_size_x=8) in; layout(std140, binding = 0) buffer blockA { float f[8]; } instanceA; layout(std140, binding = 1) buffer blockB { float f[8]; }; void main() { float data = instanceA.f[gl_LocalInvocationIndex]; f[gl_LocalInvocationIndex] = data; } // HLSL RWByteAddressBuffer _instanceA: register(u0); RWByteAddressBuffer _blockB: register(u1); float float_Load(RWByteAddressBuffer buffer, uint loc) { float result = asfloat(buffer.Load(loc)); return result; } void float_Store(RWByteAddressBuffer buffer, uint loc, float value) { buffer.Store(loc, asuint(value)); } void gl_main() { float _data = float_Load(_instanceA, 0 + 16 * gl_LocalInvocationIndex); float_Store(_blockB, 0 + 16 * gl_LocalInvocationIndex, _data); } We will do below things in the following patches: 1. Modify the intermediate tree to flatten all ssbo usages to: assign_to_ssbo := ssbo_access_chain = expr_no_ssbo; assign_from_ssbo := lvalue_no_ssbo = ssbo_access_chain; e.g. intanceA.a +=1; ->tmp = intanceA.a; intanceA.a = tmp + 1; while(++instanceA.a < 16) { } -> int PreIncrement(out int a) { a += 1; return a; } tmp = instanceA.a; while(PreIncrement(tmp) < 16) { instanceA.a = tmp } 2. Add offset calculation for structure and array of arrays. TODOs have been marked in the corresponding places in this patch. 3. Improve helper functions so that they can process all possible types. TODOs have been marked in the corresponding places in this patch. 4. Process the swizzle situation. TODOs have been marked in the corresponding places in this patch. A possible method is to extend current helper functions like below: *_Load(RWByteAddressBuffer buffer, uint loc, bool isSwizzle, uint4 swizzleOffset) Bug: angleproject:1951 Test: angle_end2end_tests Change-Id: I68ae68d5bb77d0d5627c8272627a7f689b8dc38b Reviewed-on: https://chromium-review.googlesource.com/848215 Reviewed-by: Olli Etuaho <oetuaho@nvidia.com> Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jiajia Qin <jiajia.qin@intel.com>

As the last parameter of the HLSL intrinsic functions InterlockedExchange and InterlockedCompareExchange is not optional, when there is a call of either atomicExchange or atomicCompSwap without return value, we add a temporary variable for it, so that we can directly translate all of such calls in outputHLSL.cpp. BUG=angleproject:2682 TEST=angle_end2end_tests Change-Id: I7e9c6d3c7d1846c865909b2f5a26592846c82582 Reviewed-on: https://chromium-review.googlesource.com/1161744 Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Jiawei Shao <jiawei.shao@intel.com>
