- MVKInstance reorganize list of entry points for visual clarity (unrelated).
- Fixes to deprecation documentation (unrelated).
- mvkStringsAreEqual() add small performance optimization (unrelated).
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Most of the functionality has long been replaced by the official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.
- Also rename kMVKCachedColorAttachmentCount to kMVKMaxColorAttachmentCount and
kMVKCachedViewportScissorCount to kMVKMaxViewportScissorCount and (unrelated)
- MVKPipeline validate depth & stencil formats before setting frag shader depth
and stencil builtins, and before setting formats in MTLRenderPipelineDescriptor.
- MVKCmdClearAttachments always set depth/stencil format if subpass includes
a depth or stencil attachment, even if they are not being cleared.
- MVKRenderingAttachmentIterator add synthetic attachment if depth or stencil
attachment is not provided, but image format supports both depth and stencil.
- MVKRenderSubpass add separate getDepthFormat() & getStencilFormat(),
and isDepthAttachmentUsed() & isStencilAttachmentUsed() and use
instead of testing pixel format for depth and stencil components.
- Add MVKRenderingAttachmentIterator class to consistently iterate,
and take actions, on the attachments in VkRenderingInfo to create
synthetic MVKRenderPass and extract image views and clear colors.
- Remove mvkCreateRenderPass() and mvkCreateFramebuffer() in favor
of additional constructors, and remove mvkGetDepthStencilFormat() in
favor of retrieving formats for separate depth and stencil attachments.
- MVKRenderpass constructors reorganize order of adding attachments and
subpasses, and connecting the two.
- Renmame MVKRenderPassAttachment to MVKAttachmentDescription.
- MVKPipeline reorganize member variables to minimize gaps in content
and remove unnecessary _isRasterizingDepthStencil member var (unrelated).
- MVKDevice track VkBuffers marked with VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT.
- Add SPIRVToMSLConversionResultInfo::usesPhysicalStorageBufferAddressesCapability
to detect and track shaders that use PhysicalStorageBufferAddresses capability,
and track such shader stages within pipeline.
- MVKResourcesCommandEncoderState encode usage of VkBuffers marked with
VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT when pipeline uses
PhysicalStorageBufferAddresses capability.
- Rename MVKResourcesCommandEncoderState::encodeArgumentBufferResourceUsage()
to encodeResourceUsage().
- MVKDevice move some functions to public scope and remove friend classes.
- MVKDeviceMemory ensure _vkMemAllocFlags is always initialized (unrelated).
- Rename MVKFoundation template method contains() to mvkContains() (unrelated).
- Add MVK_XCODE_14_3 macro to compile for iOS/tvOS 16.4 and above.
- Add support for BC compression on iOS/tvOS 16.4 and above where supported.
- Consolidate MVKPixelFormats::modifyMTLFormatCapabilities(mtlDev)
and centralize querying MTLDevice format methods for all platforms.
- Fix memory leak when waiting on timeline semaphores.
- For correctness, set VkPhysicalDeviceLimits::lineWidthGranularity to 1.
- Update MoltenVK to version 1.2.4.
- Update Whats_New.md document with recent changes.
- Cleanup VkPhysicalDeviceShaderAtomicFloatFeaturesEXT enablement and documentation.
- Cleanup VkPhysicalDevicePipelineCreationCacheControlFeaturesEXT enablement.
- Expand MVK_CONFIG_TRACE_VULKAN_CALLS to log thread ID only if requested.
- Add MVKCompressor template class, and mvkCompress() & mvkDecompress()
functions to support general data compression.
- Add MVKConfiguration::shaderSourceCompressionAlgorithm and
env var MVK_CONFIG_SHADER_COMPRESSION_ALGORITHM to support
compressing MSL shader source code held in a pipeline cache.
- Add MVKShaderCompilationPerformance::mslCompress and mslDecompress
to allow performance of MSL compression to be tracked and queried.
- Add support for logging performance stats accumulated in a VkDevice,
when it is destroyed. Good for CTS testing.
- Change MVKConfiguration::logActivityPerformanceInline boolean to
activityPerformanceLoggingStyle enumeration value.
- Add MVK_CONFIG_ACTIVITY_PERFORMANCE_LOGGING_STYLE environment variable and
build setting to set MVKConfiguration::activityPerformanceLoggingStyle value.
- Don't retain converted MSL source code in MVKShaderModule.
- Add SPIRVToMSLConversionResult and GLSLToSPIRVConversionResult
structures to capture all feedback from shader conversions.
- Fix crash when VkCommandBufferInheritanceInfo::renderPass is VK_NULL_HANDLE.
- Do not clear attachments when dynamic rendering is resumed.
- Allow ending dynamic rendering to trigger next multiview pass if needed.
- Move deciding to begin next multiview pass to MVKCommandEncoder.
- Fix premature caching of occlusion query results during tessellation rendering.
Tessellation ends Metal renderpass for compute control and eval stages.
Wait until end of Metal renderpass after rasterization stage.
- vkCmdCopyQueryPoolResults(): Fix loss of queries when query
count is not a multiple of GPU threadgroup execution width.
- Disable occlusion recording while clearing attachments or render area.
- MVKCmdClearAttachments improve labelling of MTLDebugGroup to better
distinguish clearing renderpass render area from vkCmdClearAttachments()
in an Xcode GPU capture (unrelated but helpful during debugging).
- MVKCmdClearAttachments re-order member variables to
optimize memory requirements (unrelated).
- MVKCommandBuffer remove unused renderpass tracking functions (unrelated).
- Revert mvkRoundHalfToEven() to static inline instead of constexpr,
because internal use of std::remainder() is not constexpr until C++23.
- Replace non-template constexpr functions with static constexpr.
- Update Github CI to default to use Xcode 14.2,
and macos-latest (which is now macos-12).
