VK_FORMAT_E5B9G9R9_UFLOAT_PACK32 on macOS Apple Silicon.
On Apple Silicon (iOS/tvOs/macOS M1), format VK_FORMAT_E5B9G9R9_UFLOAT_PACK32
is fully supported as a color attachment except that format components cannot
be individually write-enabled. All components must either be write-enabled or
write-disabled together. This is causing several hundred Vulkan CTS blending
tests to fail on M1. The least intrusive behavioural change to allow the CTS
tests to report Not Supported instead, is to disable blending for this format.
The same set of CTS tests either fails or passes on different GPUs
based on whether or not we adjust float clear colors by one ULP.
Add MVKFloatRounding enum.
Add MVKPhysicalDeviceMetalFeatures::clearColorFloatRounding.
Disable ULP adjustment for clear colors on Apple Silicon.
For consistency and to simplify bookkeepping, calculate
clear color ULP adjustment from bit width of format component.
Update MoltenVK version to 1.1.5.
Update VK_MVK_MOLTENVK_SPEC_VERSION to 32.
across separate render encoders within a single Metal command buffer (Vulkan submit).
Add MVKCommandEncodingContext to track information across multiple
MVKCommandEncoders, and use it to track temporary visibility buffer and offset.
Add support for more than one temporary visibility buffer per MTLCommandBuffer
when current temporary visibility buffer is exhausted.
Don't allow memoryless storage for VK_IMAGE_USAGE_INPUT_ATTACHMENT_BIT.
Memoryless storage for VK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT descriptors
requires support for, and use of, shader framebuffer fetch.
Remove compile-time checking for MVK_APPLE_SILICON before disabling memoryless storage
for buffers and images, since the requirement exists for all platforms, and memoryless
storage will already otherwise be disabled on other platforms anyway.
On command buffer submission failure, if MVKConfiguration::resumeLostDevice enabled,
do not release waits on VkDevice, and do not return VK_ERROR_DEVICE_LOST, unless
VkPhysicalDevice is also lost.
Adjust VkPhysicalDeviceLimits values:
- minMemoryMapAlignment raised to MIN of 64 per Vulkan spec.
- pointSizeRange upper limit to 511 per Metal.
- lineWidthGranularity to 0 per Vulkan spec when wideLines disabled.
- maxSamplerLodBias set to 4 to cover setting in shader.
to each other to find cached shader, only consider current shader stage resources.
Rename more references to ShaderConverterContext to ShaderConversionConfig.
Rename kMVKShaderStageMax to kMVKShaderStageCount
to clarify it's common use in array sizing and for loops.
Change mvkConfig() to return reference instead of pointer
to improve syntactic sugar to use . instead of ->.
Update MoltenVK version to 1.1.4.
Update What's New document.
Enable MVKConfiguration::preallocateDescriptors and
MVK_CONFIG_PREALLOCATE_DESCRIPTORS by default.
Rename MVKDescriptorTypePreallocation to MVKDescriptorTypePool.
For memoryless attachments, setting renderpass load and store
actions to "load" and "store" triggers Metal validation errors.
Refactor determination of renderpass MTLLoadAction and MTLStoreAction.
For memoryless attachments, replace load with don't care,
and store with resolve or don't care.
Don't assume the incoming CAMetalLayer has default (no-op) values for colorspace and
wantsExtendedDynamicRangeContent properties, since they could have been set externally.
Ensure the Vulkan app has control over both of these properties.
vkCreateSwapchainKHR() returns VK_ERROR_FORMAT_NOT_SUPPORTED for unsupported colorspaces.
Restore support for VK_COLOR_SPACE_HDR10_HLG_EXT and VK_COLOR_SPACE_HDR10_ST2084_EXT
under Xcode12 that was removed due to App Store conflicts using older enum values.
Introduce MVKConfigAdvertiseExtensionBits enum to specify multiple API config values in
a Vulkan-friendly manner, while automatically documenting the same values for env vars.
External libraries in particular make liberal use of assert() calls, which bypass
error catching, sometimes causing crashes rather than catch errors and moving on.
LunarG is planning to retire the LunarG/VulkanSamples repository.
Remove dependency to it, and remove the affected Hologram and API-Samples demo apps.
Update documents, including directing developers to the
KhronosGroup/Vulkan-Samples repository for official demo apps.
Remove SPIRV-Cross/ qualifier from include references to SPIRV-Cross header files.
Remove glslang/ qualifier from include references to glslang header files.
This change allows easier integration with app build scripts.
Add MVKConfiguration::apiVersionToAdvertise and MVK_CONFIG_API_VERSION_TO_ADVERTISE
env var to configure MoltenVK to advertise a particular Vulkan version.
Advertise MVKConfiguration::apiVersionToAdvertise in:
vkEnumerateInstanceVersion()
vkGetPhysicalDeviceProperties()
vkEnumerateInstanceLayerProperties()
vkEnumerateDeviceLayerProperties()
Add MVKConfiguration::advertiseExtensions and MVK_CONFIG_ADVERTISE_EXTENSIONS
env var to configure MoltenVK to not advertise support for any Vulkan extensions.
Refactor population of MVKConfiguration from environment variables to better
support validating and baking config values set by app.
Update MoltenVK version to 1.1.3.
Update VK_MVK_MOLTENVK_SPEC_VERSION to 31.
Refactor auto GPU capture code to support both device and frame capture.
Add ability to automatically capture first GPU frame by setting
`MVK_CONFIG_AUTO_GPU_CAPTURE_SCOPE` to `2`.
Wrap GPU capture in autorelease pool to handle both cases of capture call
being made in run loop as in an app GUI, or in one-shot app like CTS.
Add SPIRVToMSLConversionResults::isPositionInvariant to query
position invariance from SPIR-V.
MVKDevice::getMTLCompileOptions() takes into consideration need to preserve invariance.
MVKShaderModule compile MSL to preserve invariance if required by shader.
Support querying SignedZeroInfNanPreserve execution mode
from SPIR-V to disable fast-math for individual shaders.
Clean up namespace references in SPIRVToMSLConverter.cpp.
MVKConfiguration access is now global, and the VkInstance provided in the
vkGet/Set/MoltenVKConfigurationMVK() functions is ignored. This allows these
functions to be provided with a VkInstance object that originates from a
different Vulkan layer than MoltenVK, without risking breaking the API.
MVKConfiguration extended to cover all MoltenVK environment variables.
Move all environment variable declarations to MVKEnvironment.h.
Add MVKEnvironment.cpp to define config functions.
Cleanup .m files to use MVKCommonEnvironment.h instead of MVKEnvironment.h.
