This just provides support for the `SPV_KHR_non_semantic_info`
extension, which supports extended instruction sets that do not affect
the semantics of a SPIR-V shader (e.g. debug info). SPIRV-Cross already
handles these instruction sets, so no additional work is required on our
part to support this extension.
This extension has a direct Metal equivalent in the
`-[MTLDevice sampleTimestamps:gpuTimestamp:]` method. However, that
method returns CPU timestamps in the Mach absolute time domain, which is
*not* that of `CLOCK_MONOTONIC_RAW` but of `CLOCK_UPTIME_RAW`. The
function that corresponds to `CLOCK_MONOTONIC_RAW` is
`mach_continuous_time()`. Therefore, this implementation uses the
`mach_continuous_time()` function for the CPU timestamp. Perhaps we
should lobby the WG for `VK_TIME_DOMAIN_CLOCK_UPTIME_RAW_EXT`.
This turned out to be a little bit more involved than I had hoped. But,
with this, we can now use the `VK_FORMAT_A4R4G4B4_UNORM_PACK16` and
`VK_FORMAT_A4B4G4R4_UNORM_PACK16` formats from shaders, use them as blit
sources, and even clear them. Storage images and render targets of these
formats aren't supported, however. To support the latter would require
the insertion of a swizzle into the fragment shader before returning.
The former cannot be reasonably supported.
As of macOS Big Sur and iOS/tvOS 14, the `discard_fragment()` function
in MSL is defined to have demote semantics; that is, fragment shader
output is discarded, but the fragment shader thread continues to run as
a helper invocation. This is very useful for Direct3D emulation, since
this is the semantic that HLSL `discard` has.

The VK_MVK_moltenvk extension has never been brought inside Vulkan, and
the functions have never been supported by the Vulkan Loader and Layers.
Most of the functionality has long been replaced by the official
VK_metal_objects extension.
- Remove VK_MVK_moltenvk as an advertised extension.
- Refactor vk_mvk_moltenvk.h header file into separate headers files:
- mvk_config.h - Valid public config functions
- mvk_private_api.h - Valid development debugging functions used with care
- mvk_deprecated_api.h - Formally deprecated functions.
- Retain skeleton vk_mvk_moltenvk.h header file for legacy compatibility only.
- Update documentation and header comments to explain changes.
- Cleanup VkPhysicalDeviceShaderAtomicFloatFeaturesEXT enablement and documentation.
- Cleanup VkPhysicalDevicePipelineCreationCacheControlFeaturesEXT enablement.
- Expand MVK_CONFIG_TRACE_VULKAN_CALLS to log thread ID only if requested.
- Support querying scaling capabilities and present mode compatibilies
when querying surface capabilities.
- Rename MVKPresentTimingInfo to MVKImagePresentInfo and add present mode
and fence to support dynamic present mode changes and fence signaling.
- MVKPresentableSwapchainImage remove static functions from class declaration.
- MVKSwapchain support releasing swapchain images on command.
- MVKSwapchain support configuring with scaling and gravity info, apply it to
CAMetalLayer.and do not return VK_SUBOPTIMAL_KHR if swapchain was configured
with scaling info.
- Rename MVKSwapchain::acquireNextImageKHR to acquireNextImage.
- CAMetalLayer naturalDrawableSizeMVK compute precise drawable size.
- CAMetalLayer remove obsolete and unused updatedDrawableSizeMVK method.
- Rename MVKConfiguration::swapchainMagFilterUseNearest to
swapchainMinMagFilterUseNearest to apply CAMetalLayer size
filtering to both magnification and minification, and rename
corresponding env var MVK_CONFIG_SWAPCHAIN_MAG_FILTER_USE_NEAREST
to MVK_CONFIG_SWAPCHAIN_MIN_MAG_FILTER_USE_NEAREST.
- Detect when size of surface has changed under the covers.
- Change rounding of surface size provided by Metal from truncation to
rounding-with-half-to-even.
- Remove MVKLogSizeOf() logging macro as redundant to mvkPrintSizeOf() macro.
- 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.
VK_EXT_descriptor_indexing extension is enabled.
- Change MVKConfiguration::useMetalArgumentBuffers to enum instead of boolean
and default to enabling Metal argument buffers for VK_EXT_descriptor_indexing.
- Leave Metal argument buffers disabled by default until they are improved.
- Enable VkPhysicalDeviceVulkan12Features::descriptorIndexing.
- Add MVKPhysicalDeviceVulkan12FeaturesNoExt to track and enable Vulkan 1.2
features not part of any prior extensions absorbed by Vulkan 1.2.
- Update VK_MVK_MOLTENVK_SPEC_VERSION to version `36`.
- MVKDeviceTrackingMixin remove unnecessary inline declarations.
- MoltenShaderConveter tool support Metal Argument Buffers and MSL 3.0.
- Enable shaderSignedZeroInfNanPreserveFloat16 and
shaderSignedZeroInfNanPreserveFloat32.
Other float control properties are not settable in Metal.
- MVKShaderModule log whether compiling with fast math enabled.
- Update MoltenVK_Runtime_UserGuide.md and Whats_New.md documents.
- runcts script enable MVK_CONFIG_FAST_MATH_ENABLED by default.
- Add [CAMetalLayer screenMVK] extension method to retrieve screen.
- If the layer has a delegate view, use it to locate the screen, otherwise
revert to iterating across windows, looking for the CAMetalLayer, to identify
the window the layer is in, from which to retrieve the screen.
- Fix the iteration of the layer hierarchy, to accommodate that Apple may
add superlayers to the CAMetalLayer under the covers.
- Update MoltenVK_Runtime_UserGuide.md to encourage the app to ensure the view
is the delegate of the CAMetalLayer, to more efficiently access the screen.
Support by the MTLDevice for Metal Tier 2 argument buffers has an
impact on both descriptor indexing and buffer device address support.
Add MVKPhysicalDeviceMetalFeatures::argumentBuffersTier, to track
the MTLDevice argument buffers support tier, set it from
[MTLDevice argumentBuffersSupport], and subsequently enable support for
VK_KHR_buffer_device_address and VK_EXT_buffer_device_address extensions,
and set descriptor indexing resource counts, based on it.
Update documentation requirements.
- Update to latest SPIRV-Cross to support `SPV_KHR_physical_storage_buffer`
for `VK_KHR_buffer_device_address` and `VK_EXT_buffer_device_address`
- Add support for `VK_EXT_buffer_device_address` extension.
- Advertise support for `VK_KHR_buffer_device_address`
and `VK_EXT_buffer_device_address` on macOS 12.5.
- Add appropriate extension reporting and enablement for
`VkPhysicalDeviceBufferDeviceAddressFeatures`,
`VkPhysicalDeviceBufferDeviceAddressFeaturesEXT`, and
`VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR`.
- Support reading `VkMemoryAllocateFlagsInfo` to identify memory allocations that
need to support buffer pointer access (in case needed in future on non-shared memory).
- Update `Whats_New.md` and `MoltenVK_Runtime_UserGuide` documents.
Add VK_KHR_separate_depth_stencil_layouts and enable its features.
Metal generally ignores image layouts, so nothing further needed.
Update Whats_New.md and MoltenVK_Runtime_UserGuide.md documents
with recently-added extensions.
Passes almost all supported separate_layouts CTS tests, with the
few remaining tests failing due to issues with unrelated capabilities.
Unrelated cleanup:
- MVKDevice enable extensions before features.
- MVKDevice reorder ivar declarations to reduce
memory layout gaps, and define default values.
- Rename VkSemaphoreStyle to MVKSemaphoreStyle to
remove potential conflicts with Vulkan Vk name space.
Update README.md and MoltenVK_Runtime_UserGuide.md to document the impact
of the VK_KHR_portability_enumeration extension during runtime loading on macOS.
Update MoltenVK version to 1.1.10.
Supports only setting custom sample locations in subpasses via
vkBeginRenderpass. Does not support setting custom sample locations via
vkCmdBindPipeline or vkCmdSetSampleLocationsEXT, although collects that
info for possible future enhancements.
- MVKPhysicalDevice track platform support and respond to property queries.
- MVKCmdBeginRenderPassBase collect subpass custom sample locations.
- MVKPipeline support dynamic state values beyond 31.
- MVKPipeline collect custom sample locations.
- Add MVKCmdSetSampleLocations to support vkCmdSetSampleLocations
to collect dynamic custom sample locations.

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.
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.
