- Update maxClipDistances and maxCombinedClipAndCullDistances to more accurate values.
- Update maxDrawIndexedIndexValue to acknowledge primitive restart.
- Ensure Vulkan public symbols are not stripped from the library when
statically linked to an app that calls all Vulkan functions dynamically.
- Per Vulkan 1.2 spec, support calling vkGetInstanceProcAddr() with a
null instance, when vkGetInstanceProcAddr itself is the function name.
- Replace uses of strcmp() with mvkStringsAreEqual() to protect against
null pointers, and provide a direct bool output (unrelated cleanup).
- Fix Metal validation error caused by CAMetalDrawable released before
MTLCommandBuffer is finished using it.
- When presenting, MVKPresentableSwapchainImage retains in-flight
CAMetalDrawable until MTLCommandBuffer completion.
- Fix memory leak of MVKFences and MVKSemaphores when a
swapchain image is acquired more than it is presented.
- Force MVKPresentableSwapchainImage to untrack any tracked fences or
semaphores when it is destroyed.
- Update MoltenVK version to 1.2.2.
Metal uses MTLRenderPassDescriptor properties renderTargetWidth,
renderTargetHeight, and renderTargetArrayLength to preallocate tile memory
storage on machines using tiled rendering. This memory preallocation is not
necessary if we are not rendering to attachments, and some apps actively
define extremely oversized framebuffers when they know they are not rendering
to actual attachments, making this internal tile memory allocation even more
wasteful, occasionally to the point of triggering OOM crashes.
Update MoltenVK version to 1.2.2.
of VK_KHR_shader_float_controls.
The introduction of shaderSignedZeroInfNanPreserveFloat32 was causing Metal
fast math to be aggressively disabled by the use of SignedZeroInfNanPreserve
in shaders in some apps, causing a regression in shader performance in those apps.
- Change MVKConfiguration::fastMathEnabled from bool to enumeration to distinguish
between always using fast math or allowing shaders to selectively disable it.
- Default value to fast math always.
Push constants and attachment clearing can temporarily override Metal buffer
bindings for descriptor sets and vertex attributes. Mark the overridden buffer
bindings and ensure they are reinstated when the pipeline is updated.
- Add MVKMTLBufferBinding::isOverridden to track if buffer binding is
temporarily overridden.
- Rename MVKResourcesCommandEncoderState::markIndexDirty()
to markBufferIndexOverridden() to mark buffer bindings as overridden.
- Rename MVKGraphicsResourcesCommandEncoderState::markBufferIndexDirty()
to markBufferIndexOverridden().
- Rename MVKComputeResourcesCommandEncoderState::markBufferIndexDirty()
to markBufferIndexOverridden().
- Add MVKResourcesCommandEncoderState::markOverriddenBufferIndexesDirty()
to mark overridden buffer bindings as dirty.
- Add MVKGraphicsResourcesCommandEncoderState::markOverriddenBufferIndexesDirty()
and call when render pipeline change is encoded
- Add MVKComputeResourcesCommandEncoderState::markOverriddenBufferIndexesDirty()
and call when compute pipeline change is encoded.
Do this even if `OPTIMAL` tiling were requested. Vulkan mandates support
for image atomics on `OPTIMAL`-tiled `R32_UINT` and `R32_SINT` images.
In a way, this is "optimal"; image atomics won't work without this.
Advertise support for atomics on `OPTIMAL` tiled images now.
Fixes at least two CTS tests under
`dEQP-VK.compute.basic.image_atomic_op_*`.
This has caused us nothing but trouble. The code to build up the vertex
descriptor is fragile; we can rip that out now.
Also, make sure to positively identify per-patch blocks as per-patch.
For those, the individual members have the `Patch` decoration.
Update SPIRV-Cross to pull in the changes needed for this.
Fixes 66 tests in the CTS.
