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.
- Redefine enumeration values of MVKPrefillMetalCommandBuffersStyle.
- Add option to defer encoding prefilled MTLCommandBuffer to queue submission.
- Remove option to create an autorelease pool in the MVKCommandEncoder
to span immediate command encodings, because it causes crashes when
multiple command buffers were overlapping prefilling on the same thread.
- Replace MTLCommandEncoder retain/release macros with template member functions.
- Rename MVKCommandPool::newMTLCommandBuffer() to getMTLCommandBuffer()
and do not retain the returned MTLCommandBuffer (unrelated).
- Revert MoltenVK logging to use stderr instead of stdout (unrelated).
- Merge branch from master.
- Add MVKPrefillMetalCommandBuffersStyle enumeration to enable prefilling,
and configure memory recovery options.
- Redefine MVKConfiguration::prefillMetalCommandBuffers as a value from
MVKPrefillMetalCommandBuffersStyle instead of a simple boolean. Set the
values of MVKPrefillMetalCommandBuffersStyle and the default value of
MVKConfiguration::prefillMetalCommandBuffers to be compatible with
legacy use of this setting as a simple enable/disable boolean value.
- MVKCommandEncoder track prefill style, and support option to maintain
a Metal autorelease pool that is created on vkBeginCommandBuffer()
and drained on vkEndCommandBuffer(), when prefiling a command buffer
from a single thread, and an option to wrap each command addition in
a separate @autoreleasepool{} scope to create and drain an autorelease
pool at every command addition to the Vulkan command buffer, when
prefilling a single command buffer from multiple threads.
- MVKCommandEncoder retain Metal encoders when prefilling, because
prefilling may span multiple autorelease pools.
- MVKCommandEncoder clean up memory leak of MTLBlitPassDescriptor
during prefilling.
- MVKCommandEncoder rearrange declarations of MVKCommandUse member
variables to tighten up class memory use (unrelated).
- MVKCommandBuffer remove unnecessary inline declarations (unrelated).
- Change MoltenVK logging to use stdout instead of stderr (unrelated).
- If MTLEvents are unusable, fallback to single queue.
- Adjust values of MVKVkSemaphoreSupportStyle enumeration.
- For legacy compatibility, if legacy semaphoreUseMTLEvent and
semaphoreUseMTLFence are both disabled, use CPU callback emulation.
- Update and expand related documentation in vk_mvk_moltenvk.h.
- Remove separate extension entry points for 1.3 promoted
vkCmdBeginRenderingKHR() and vkCmdEndRenderingKHR() functions,
which caused build breaks when MVK_HIDE_VULKAN_SYMBOLS=1.
- For consistency, hide vkGetMoltenVKConfigurationMVK(),
vkSetMoltenVKConfigurationMVK(), and vkGetVersionStringsMVK()
when MVK_HIDE_VULKAN_SYMBOLS=1, which was an oversight in original
implementation of hiding Vulkan functions.
- Update build `README.md` for generic command line build settings
and MVK_HIDE_VULKAN_SYMBOLS in particular.
- Set MVK_VULKAN_API_VERSION from VK_API_VERSION_1_2.
- Update MoltenVK version to 1.2.0.
- Remove several previously overlooked extension suffixes
in use of promoted Vulkan struct and enum values.
- Update documentation.
