- 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.
Makefile currently special-case MVK_HIDE_VULKAN_SYMBOLS as the only
variable that can be customised on the command line. There are many
others that are useful though, such as MVK_LOG_*. This commit
makes the Makefile more generic and allows to forward to xcode whatever
variable was declared on the command line.
MSL: Handle descriptor aliasing of raw buffer descriptors.
MSL: Do not attempt to alias push constants.
MSL: Report unsupported 64-bit atomics.
MSL: Add more keywords to reserved set.
when building with MVK_HIDE_VULKAN_SYMBOLS=1.
Alias vkGetBufferDeviceAddressEXT to core function,
and add it as promoted extension function in MVKInstance.
It is always legal in Vulkan to read a builtin, particularly
`BuiltInPosition`, even if it weren't written by the previous stage. The
CTS tests that this scenario works in the driver.
Update SPIRV-Cross to pull in a change required for this.
Fixes 8 CTS tests under `dEQP-VK.pipeline.*.no_position`. (Eight other
tests worked solely by accident without this change.)
- Support option to use MTLEvents for Vulkan semaphores on NVIDIA and Rosetta2.
- Add public MVKVkSemaphoreSupportStyle enumeration.
- MVKConfiguration replace deprecated legacy booleans semaphoreUseMTLEvent,
and semaphoreUseMTLFence with enumerated semaphoreSupportStyle.
- Alias legacy semaphoreUseMTLEvent to semaphoreSupportStyle and support legacy
use of semaphoreUseMTLFence and semaphoreUseMTLEvent for backwards compatibility.
- MVKConfiguration rename recently renamed semaphoreUseSingleQueue back to
semaphoreUseMTLFence for backwards compatibility.
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.
Vulkan 1.2 includes several optional extensions that are not currently
supported by Metal. These include:
- VK_KHR_draw_indirect_count (and VK_AMD_draw_indirect_count)
- VK_KHR_shader_atomic_int64
- VK_KHR_vulkan_memory_model
- VK_EXT_sampler_filter_minmax
Capability flags for these extensions are included in
VkPhysicalDeviceVulkan12Features and VkPhysicalDeviceVulkan12Properties,
and in parallell extension-specific structures.
This addition provides no new user functionality. For consistency with
VkPhysicalDeviceVulkan12Features and VkPhysicalDeviceVulkan12Properties,
the changes here flush out the extension/Vulkan 1.2 parallel functionality,
with a view to prepare to include the functionality consistently in both
an extension and Vulkan 1.2, should the functionality become available
in a future version of Metal.
This change also explicitly includes the optional extensions in
MVKExtensions.def, but disables them from user visibility.
- 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.
When presenting drawables in the future, the MVKPresentableSwapchainImage
and MVKSwapchain were both being retained by the drawable-presented callback,
so that the presentation timing info can be recorded on the swapchain.
Unfortunately, in the case where the presentation timing is set far enough
into the future (I'm looking at you CTS), the swapchain, and even the
CAMetalLayer's view may be destroyed, causing occasional bad access crashes.
- MVKSwapchainImage don't retain() the swapchain, and move clearing the
swapchain from the destructor to destroy(), so the MVKSwapchain is not
necessarily retained by the MVKSwapchainImage, for a drawable being
presented in the future.
- MVKSwapchainImage add a lock around clearing swapchain and accessing
it from callbacks.
- Add lockable releaseLayer() function in both MVKSwapchain and MVKSurface,
which is called from both layer observer and destructor, to handle race
conditions better.
- MVKSwapchain::initCAMetalLayer() call MVKSurface::getCAMetalLayer() only once.
- Update MoltenVK version to 1.1.12.
- Update What's New document.
