Declare _formatDescriptions[] in mvk_datatypes.mm as officially writable
because Clang now locates static const in non-writable memory.
Update build settings to Xcode 11.
Update MoltenVK_Runtime_UserGuide.md about embedding `libMoltenVK.dylib` in an application.
Remove obsolescence log message for vkCreateMacOSSurfaceMVK()
and vkCreateIOSSurfaceMVK() functions.
Fix test for alignment of invalid pixel formats.
Update dependency libraries to match Vulkan SDK 1.1.121.
Update to renaming of VK_INTEL_shader_integer_functions2
enums and structs in latest Vulkan headers.
Update Whats_New.md document.
This extension allows fragment shaders to delineate critical sections
where pairs of invocations may not execute simultaneously. In Metal, the
nearest equivalent functionality is raster order groups. This
implementation is thus implemented on top of them.
Update SPIRV-Cross to pull in SPIR-V support for this new extension.
MVK_ALLOW_METAL_FENCES environment variable.
Refactor MVKSemaphore class into separate MVKSemaphoreMTLFence,
MVKSemaphoreMTLEvent, and MVKSemaphoreEmulated subclasses.
Add MVK_ALLOW_METAL_FENCES environment variable to optionally
enable using MTLFence for Vulkan semaphores.
Add MVKPhysicalDeviceMetalFeatures::fences to track MTLFence availability.
Update VK_MVK_MOLTENVK_SPEC_VERSION to version 22.
Use parallelism more effectively to massively cover buffer with
multiple full threadgroups, instead of serial looping in shader.
Performance improvement measured at 150x (yes...x not %) on macOS.
MVKCmdFillBuffer move validation test to setContent() instead of encode().
One set of MVKSemaphore::encodeWait() & encodeSignal() functions either use MTLEvent
or not, and are called twice with and without MTLCommandBuffer to handle both cases
of encoded and inline waits and signals.
Always submit surface presentations using MTLCommandBuffer.
MVKConfiguration::presentWithCommandBuffer is now obsolete.
Fix memory leak of MVKQueueCommandBufferSubmissions with no content.
MVKExtensionList add support for identifying and enabling instance or device extensions.
Rename MVKLayer::getExtensionProperties() to getInstanceExtensionProperties() and
MVKLayer::getSupportedExtensions() to getSupportedInstanceExtensions().
Largely minimal for now. Much of it, particularly most of the
interactions with `VK_KHR_swapchain`, was already implemented
previously. The only interesting bits are the `vkCmdDispatchBase()`
command, and the ability to create arbitrary swapchain images and bind
them to swapchain memory, which requires the use of the previously
implemented `VK_KHR_bind_memory2` extension. Most everything else can be
safely ignored for now.
Non-zero dispatch bases use the compute stage-input region to pass the
dispatch base group to the shader, which must manually adjust the
`WorkgroupId` and `GlobalInvocationId` builtins, since Metal does not do
this for us. I have tested that this approach works well--at least, well
enough to pass the CTS.
Because of the ability to bind arbitrary images to swapchain memory,
I've sucked the guts out of `MVKSwapchainImage` and into `MVKSwapchain`
itself. Availability and drawable management is now performed by the
swapchain object. `MVKSwapchainImage` is now just a specialized kind of
image, created when requested with a `VkImageCreateSwapchainInfoKHR`
structure.
Update SPIRV-Cross so we can support the `vkCmdDispatchBase()` command.
One more step towards Vulkan 1.1.
Add MVKEvent class. MVKEventNative subclass uses native MTLEvent. MVKEventEmulated
subclass uses emulation using CPU blocking and MTLCommandBuffer completion handling.
MVKConfiguration::synchronousQueueSubmits now disabled by default if MTLEvents are not supported.
Document updated use of MVK_ALLOW_METAL_EVENTS and MVK_CONFIG_SYNCHRONOUS_QUEUE_SUBMITS
environment variables and synchronousQueueSubmits config setting, in vk_mvk_moltenvk.h.
MVKDevice check highest queue family index before expanding queue family collection.
MVKVector add bounds check to at(), [], front() & back() functions.
MVKDispatchableVulkanAPIObject::getVkHandle() re-establishes the loader magic number
before returning, in case the loader overwrote it before returning the object.
Update to latest external dependency libraries.
Rename components of VK_INTEL_shader_integer_functions2 to match 1.1.114 Vulkan spec.
Update What's New document.
Remove the descriptor set pool associated with a MVKDescriptorSetLayout when the layout
is destroyed. MVKDescriptorPool and MVKDescriptorSetLayout track each other to tell the
other when it has been destroyed.
MVKCmdCopyImage uses texture view if formats different. Enable
MTLTextureUsagePixelFormatView for VK_IMAGE_USAGE_TRANSFER_SRC_BIT.
Refactor mvkMTLTextureUsageFromVkImageUsageFlags() to clarify Metal usages
and enable views on depth-stencil attachments by default.
Retain MVKSwapchainImage before passing to MTLCommandBuffer completion handler.
Redesign MVKVulkanAPIObject retain/release functionality using atomic ref count
instead of mutex locks, to simplify design and improve performance.
Refactor SPIRVToMSLConverterContext into distinct SPIRVToMSLConversionConfiguration
and SPIRVToMSLConversionResults for conversion input and output, respectively.
Update to latest SPIRV-Cross version.
Update What's New document.
On iOS GPU family 2 and earlier:
- Allow immutable samplers to be passed to SPIRV-Cross in a format
they can be output as hardcoded constexpr samplers in MSL.
- Validate depth compare samplers are only used as immutable.
MVKMVKPipelineLayout & MVKDescriptorSetLayout can take null MVKCommandEncoder
to perform a validation pass when binding or pushing.
Reduce redundancy by combining SPIRVToMSLConverterContext structs
with compatible SPIRV-Cross structs.
Update MoltenVK version to 1.0.36.
