The "minimum list of required image formats" for OpenCL 2.x devices lists the `CL_DEPTH` and `CL_sRGBA` image channel orders, but there are footnotes for these image channel orders describing the...

Memory Consistency for Memory Objects Created from SVM Allocations

3

Found while considering memory objects created from SVM allocations for the unified SVM extension: What are the memory consistency expectations for memory objects created from SVM allocations? Some specific questions...

See discussion: https://github.com/KhronosGroup/OpenCL-Docs/pull/1375#issuecomment-2892417816 We need to add a requirement in the SPIR-V environment spec to effectively say that an OpControlBarrier with work-group scope only has defined behavior when the barrier...

Device Pointers for Memory Objects Created from SVM Allocations

1

Found while considering memory objects created from SVM allocations for the unified SVM extension: The `cl_ext_buffer_device_address` extension added a requirement for memory objects (specifically, buffers) created from SVM allocations: [CL_MEM_DEVICE_PRIVATE_ADDRESS_EXT](https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_API.html#CL_MEM_DEVICE_PRIVATE_ADDRESS_EXT):...

Found while discussing and developing the unified SVM extension: the current description for the _svm_ptr_ argument to [clEnqueueSVMMemFill](https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_API.html#clEnqueueSVMMemFill) is confusing and should be improved. For reference, the current text is:...

cl_ext_float_atomics: required minimum capabilities

1

Currently, the cl_ext_float_atomics explicitly states that there are no mandated minimum capabilities: https://registry.khronos.org/OpenCL/extensions/ext/cl_ext_float_atomics.html#_modifications_to_the_opencl_api_specification This means that an implementation could theoretically advertise support for the extension but then return zero for...

SVM tests where the size is zero

7

Here are some tests to check how SVM APIs behave when the size is zero, see: * https://github.com/KhronosGroup/OpenCL-Docs/issues/1403 These tests don't fail right now if some of the calls are...

Does the Vulkan SPIR-V and API version need to match?

1

From a review comment, see: https://github.com/KhronosGroup/OpenCL-CTS/pull/2536#pullrequestreview-3362636592 > I don't have a very strong opinion about this, but I think it should be fine to invoke glslang and target the older...

add test for a NULL local work size and a required work-group size

2

see #2501 This tests the following scenarios: 1. Execute a kernel with a required work-group size, passing `NULL` as the local work size. 2. Query the suggested work-group size for...

See: https://github.com/KhronosGroup/SPIRV-Registry/issues/357 We should add tests to ensure implementations properly handle cases when multiple OpSpecConstant instructions are decorated with the same SpecId. Rough test plan: * Top Priority: Tests for...
