Discrete GPUs use managed-memory textures, and these need to be synchronized
from GPU memory before being available for host-copying to memory using the CPU.
Metal automatically handles the reverse sync when copying from memory to a texture.
- Remove _unused_struct_padding from MVKConfiguration and MVKConfigMembers.def.
- Add kMVKConfigurationInternalPaddingByteCount to specify MVKConfiguration
internal padding byte count, for use in build time assertion check.
- MVKResource::getHostMemoryAddress() return nullptr if
MVKDeviceMemory::getHostMemoryAddress() returns null pointer,
regardless of local offset.
- Remove unnecessary enum value kMVKVkFormatFeatureFlagsTexTransfer
to reduce redundancy between read and transfer feature flag options.
- Fix spelling of mvkVkOffset3DFromMTLOrigin() (unrelated).
- MVKResource remove unnecessary inline qualifiers (unrelated).
- MVKDevice remove some obsolete commentary (unrelated).
Apple's Automatic Reference Counting automatically releases
the Metal objects returned by VK_EXT_metal_objects.
The fetchDependencies script now applies
Templates/Vulkan-Headers/VK_EXT_metal_objects-unret.gitdiff
to add an __unsafe_unretained ownership qualifier to the
Metal object declarations in vulkan_metal.h.
This should be a temporary patch until the VK_EXT_metal_objects
extension can be properly modified.
After the recent change to building dynamic frameworks and dylibs as targets
built by linking to a static library dependency, incremental builds do not
correctly link the dynamic frameworks and dylibs to the rebuilt static library.
- Delete dynamic target outputs during static target builds.
- Run platform schemes sequentially in manual order.
- Build the dynamic framework before the dylib.
- Clean up Xcode Scheme organization.
It is not entirely obvious what the dependency problem is, and why
these particular changes work. A lot of trial-and-error was required.
It's possible that Xcode dependency analysis does not correctly analyze
the flow used in MoltenVK builds.
- .gitignore exclude all directories under External, to allow
temp directories to be created during dependency developments.
- .gitignore specify MoltenVK exclusions are relative to root directory.
Xcode validates project build settings with each new Xcode release and
issues warnings to apply recommendations. We ignore these. This patch
sets the validated Xcode version to the maximum so that Xcode will
not longer issue these warnings.
Previously, libMoltenVK.dylib was created by copying and renaming
the binary from MoltenVK.framework, but this resulted in an unsigned
dylib that was not loadable.
- Create signed macOS libMoltenVK.dylib directly from Xcode.
- Refactor package_moltenvk.sh into package_dylibs.sh & package_headers.sh.
- Remove unused non-packaging Xcode schemes (unrelated).
