Add MVK_CONFIG_PREALLOCATE_DESCRIPTORS env var to enable descriptor preallocation
in pool. Add MVKDescriptor subclasses for all used VkDescriptorType values.
Support allocating MVKDescriptor subclasses via direct instantiation,
or referencing preallocated instances held in a fixed collection.
MVKDescriptor subclasses support resetting and reuse from preallocated collection.
MVKDescriptorPool optionally holds collections of preallocated descriptors,
one collection per VkDescriptorType value.
Support VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT to mark preallocated
descriptors as available when freed.
MVKDescriptorPool no longer pools MVKDescriptorSet objects, keyed by their layouts.
MVKDescriptorSet are lightweight allocations, and instances are now created and
freed by the corresponding Vulkan commands.
MVKDescriptorSetLayoutBinding instantiates appropriate MVKDescriptorBinding subclasses.
MVKDescriptorSet hold pointers to MVKDescriptorBinding instead of instances.
Remove arrays of slots from MVKDescriptorBinding. For array types, multiple
MVKDescriptorBindings map to one corresponding MVKDescriptorLayoutBinding.
Simplify logic of copying and writing to descriptors.
Add MVKPhysicalDeviceMetalFeatures::pushConstantSizeAlignment, set value to 16 (size of
float4), and ensure push constant buffers have a size that is a multiple of that value.
Update VK_MVK_MOLTENVK_SPEC_VERSION to 24.
Change MVKPhysicalDeviceMetalFeatures::dynamicMTLBuffers from boolean to uint
dynamicMTLBufferSize limit and guard dynamic buffer usage sizes against it.
Update VK_MVK_MOLTENVK_SPEC_VERSION to 23.
Remove VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT and VK_MEMORY_PROPERTY_HOST_CACHED_BIT
from MVK_VK_MEMORY_TYPE_METAL_SHARED.
Refactor MVKPhysicalDevice::initMemoryProperties() to configure memory
types and heaps in a more organized, procedural, and traceable manner.
Enhance MVKPhysicalDevice::getHasUnifiedMemory() detection of unified memory.
Simplify MVKPhysicalDevice::getVRAMSize().
On macOS MVKImage::validateUseTexelBuffer() tests the underlying device memory
directly to determine if it has coherent memory and cannot support texel buffer.
Add MVKInstance::getPhysicalDeviceCount().
Add mvkClear() template function for clearing structs and replace use of
memset(*, 0, sz) with mvkClear().
Refactor mvkCopyStruct() and rename to mvkCopy().
Add SPIRVShaderOutput::isUsed retrieved from shader reflection.
mvk::sizeOfOutput() returns zero if output var is not used.
Update to latest SPIRV-Cross version.
Fixes linear filtering when using vkCmdBlitImage(), useful for mipmap generation.
Move MVKCmdBlitImage sampler definition to shader as a constexpr sampler,
and ensure mip_filter and filter are set correctly.
Add MVKRPSKeyBlitImg::srcFilter.
Include MVKCommonEnvironment.h in MVKLogging.h.
Update MoltenVK version to 1.0.39.
Add `MVK_CONFIG_TEXTURE_1D_AS_2D` environment variable, enabled by default.
Modify 1D warning messages to recommend use of `MVK_CONFIG_TEXTURE_1D_AS_2D`.
Update to latest version of SPIRV-Cross.
Align pipeline cache contents to latest CompilerMSL::Options structure.
Clean up code signing on demo Xcode projects.
