- 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).
- Add mvkGetNaturalExtent() to consolidate retrieving the natural rounded
extent of the CAMetalDrawables that will be created by a CAMetalLayer,
based on its drawableSize and contentsScale properties.
- Replace MVKSwapchain::_mtlLayerDrawableSize with _mtlLayerDrawableExtent.
- MVKSwapchain::hasOptimalSurface() compares last, actual,
and natural rounded drawable extents of CAMetalLayer.
- Pass MVKImagePresentInfo struct by reference instead of copy.
- Remove unused boolean to pass around
VK_SWAPCHAIN_CREATE_DEFERRED_MEMORY_ALLOCATION_BIT_EXT status.
