We only support the `robustImageAccess2` feature for now. Metal's
guarantees around out-of-bounds accesses to textures give us this for
free. `nullDescriptor` should also be possible to implement, but it
needs testing. Null image descriptors will probably just work, but null
buffer pointers probably not. We may need help, either from SPIRV-Cross
or a pass in SPIRV-Tools. `robustBufferAccess2` definitely needs an
assist from SPIRV-Tools. All three are useful for Direct3D compatibility
layers (DXVK, wined3d).
Currently, when a mapping is initiated for host-coherent device memory, existing
image contents are copied from the MTLTexture to host memory. However, if
host-coherent device memory is already mapped in a long-standing memory mapping,
changes to MTLTexture content are not reflected to the host memory.
This change adds that capability to open memory mappings. When the image pipeline
barrier is applied to an image that is attached to a host-coherent device memory
that currently has an open memory mapping, the MTLTexture contents are copied to
the open host memory binding.
Add MVKMappedMemoryRange to retrieve the currently mapped range in an MVKDeviceMemory.
MVKImage cleanup use of isHostCoherent(). Let it be same as MVKDeviceMemory
and don't test for it from macOS because it is unnecessary.
Mark MVKResource::bindDeviceMemory() as virtual.
Remove use of !! from mvkIsAnyFlagEnabled().
Update What's New document for VK_KHR_sampler_ycbcr_conversion.
descriptorCount measures bytes, array indices are offsets into the buffer,
missing isInline flag in bind, missing struct VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_INLINE_UNIFORM_BLOCK_PROPERTIES_EXT.
Allow MVKImageViewPlane MTLPixelFormat to be modified by swizzle settings.
Make MVKImageViewPlane a subclass of MVKBaseDeviceObject to streamline device access.
as subclasses of MVKBaseObject for lifecycles.
Remove use of unique_ptr to manage destruction of MVKImageMemoryBinding,
MVKImagePlane, and MVKImageViewPlane instances. Instead, call destroy()
on them during destruction of MVKImage and MVKImageView.
Generally replace use of @available() with respondsToSelector:.
Add mvkMakeOSVersion() and mvkOSVersionIsAtLeast(macos,ios) to help testing OS versions.
Set maxDrawIndexedIndexValue to kMVKUndefinedLargeUInt32 instead of uint32_t max.
Report format properties only based on the primary MTLPixelFormat
of a VkFormat, not any possible substitution MTLPixelFormat.
Update MoltenVK version to 1.0.43 and VK_MVK_MOLTENVK_SPEC_VERSION to 26.
Add MVKTranslatedVertexBinding to describe a translated vertex binding, track these in
MVKGraphicsPipeline, and add a Metal vertex layout for each additional translated binding.
MVKGraphicsResourcesCommandEncoderState query MVKGraphicsPipeline for translated bindings
associated with existing bindings and binds the same MTLBuffer multiple times with
different offsets.
Support MTLPixelFormats with larger values.
MVKPixelFormats::getVkFormatProperties() return
reference and log error if unsupported VkFormat.
Remove tests for null format name strings.
Consolidate MVKPhysicalDevice::getFormatProperties() overloads.
