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.
Add link to Vulkan SDK Getting Started doc to README.md and
MoltenVK_Runtime_UserGuide.md documents.
Add Github CI badge to README.md, and remove Travis CI badge.
Make document notices of use of Markdown into comments
so they are invisible when using a Markdown reader.
This extension allows the subgroup size to vary between draw/dispatch
calls, and even allows clients to declare that full subgroups must
always be dispatched. It corresponds better to how Metal actually works.
No support for declaring a required subgroup size, unfortunately.
Define MVK_MACCAT build macro and use it to conditionally compile code to align
with build features and capabilities of Mac Catalyst platform on macOS 11.0+.
Treat Mac Catalyst as minor variation of macOS 11.0.
Update documentation.
Currently only support Mac Catalyst on macOS 11.0+, to avoid complexities of
deselecting iOS features and capabilities for Mac Catalyst on previous macOS versions.
Mac Catalyst (and Simulators) require use of XCFrameworks.
Currently unable to generate a dylib for Mac Catalyst.
Also, enable rendering caps on linear textures. This is supported on
Apple GPUs.
Conversely, disable capabilities supported by desktop GPUs that are not
supported on Apple GPUs.
Sadly, no support for 16-bit packed pixel formats on non-Apple GPUs.
MVKDevice track enabled VkPhysicalDeviceInlineUniformBlockFeaturesEXT features.
Disable prefilled MTLCommandBuffers if update after binding enabled.
Update to latest SPIRV-Cross that includes support for unsized arrays.
Increase per-stage texture count to 96 for A11 SoC's and above.
Report VkPhysicalDeviceLimits::maxPerStageDescriptorStorageImages as Metal limit of 8.
Add MVKPhysicalDeviceMetalFeatures::maxPerStageStorageTextureCount and set to 8.
Update VK_MVK_MOLTENVK_SPEC_VERSION to 29.
VK_EXT_descriptor_indexing adds no new functions, but does add six structures to
existing pNext chains. This initial commit processes these structs, but does not
yet perform any operational functionality for this extension.
Bind descriptors based on binding number within pipeline layout, not order within
layout, and descriptor set looks up descriptor using binding layout it was created with.
Moved to a new model for creation: create and potentially destroy the object
within MVKDevice::create..., to hide it from vulkan.mm where all other object
creation errors are handled. We could move to this slowly over time.
Passes all 49 private data CTS tests.
Update MVKPresentableSwapchainImage::presentCAMetalDrawable() to create a
MTLCommandBuffer scheduled-handler and present the MTLDrawable from there.
According to Apple, it is more performant to call MTLDrawable present from within a
MTLCommandBuffer scheduled-handler than it is to call MTLCommandBuffer presentDrawable:.
Pass presentation timing info as a struct to simplify calls.
