All of the resources' `applyMemoryBarrier()` methods check if the second
scope contains host operations. If they don't, they have no effect. If
there are a lot of resources, iterating them for a method that will
ultimately do nothing is wasteful. Bail out if we can see that they will
do nothing.
While `MTLFence` could be used for synchronization within a single
queue, it doesn't prevent execution across queues. For this, an
`MTLEvent` is required. Yes, this requires Metal 2.1 (macOS 10.14, iOS
12). Older versions will continue to use the old, CPU-based
implementation.
According to the Vulkan spec, semaphores must either be already signaled
or have a signal operation in progress before waiting for them. This
implementation increments the `MTLEvent`'s expected value after encoding
a wait operation, which requires this assumption to hold.
One thorny bit is acquiring a swapchain image when it is not already in
use. In this case, any semaphore provided must be signaled right away.
To accomplish this, a command buffer is executed which performs the
signal operation on the device. Alternatively, we could use an
`MTLSharedEvent`, which would allow us to signal the event on the host.
But, this could have performance implications that may not be
acceptable, just to handle this one case.
Fixes#438.
These two new methods introduced in Metal 2.1 (macOS 10.14) are more
granular, providing more control over what exactly must be sync'd. They
also work on buffer memory, meaning that buffer dependencies work
properly here.
Add MVKDebugReportCallback class.
Add MVKVulkanAPIObject class as base class of classes exposed in Vulkan API.
Remove MVKRefCountedDeviceObject class and move ref-counting to MVKVulkanAPIObject.
Rename MVKDispatchableObject class to MVKDispatchableVulkanAPIObject.
Introduce multiple inheritance mixin classes into class hierarchy.
Add MVKBaseObject::getVulkanAPIObject() function to find Vulkan API object
controlling any subobject that needs to report something.
MVKCommandResourceFactory functions pass in calling object for reporting.
Add MVKBaseObject::reportMessage() & reportError() functions.
Replace mvkNotifyErrorWithText() static function with reportError()
instance function to allow access to debug reporting.
Redefine MVKLog*() functions to call reportError() instance method.
Delete MVKLogging.cpp.
Remove MVKLogging.h from MoltenVKShaderConverter project.
Add mvk_datatypes.hpp to redirect errors in mvk_datatypes.h functions to debug
reporting. Use mvk_datatypes.hpp internally for all references to these functions.
Convert several static methods to instance methods.
Refactor platform defines in MVKSurface.h.
Explicitly count MVKExtensionList extension count to avoid relying on struct size.
Remove MVKCommandBuffer::recordResult() and use setConfigurationResult().
Change log indication of error in logs from [***MoltenVK ERROR***] to [mvk-error],
for consistency with other log level indications.
Update MoltenVK version to 1.0.35.
Put the fence back on the last submission.
This mostly reverts the last of the original change, save for a few
formatting changes and deletions of unused cruft.
Add ExternalDependencies (Debug) scheme to ExternalDependencies Xcode project.
Add --debug option to fetchDependencies script.
Support Release, Debug & Latest directories in External/build directory.
Enable DEPLOYMENT_POSTPROCESSING build setting when compiling
SPIRV-Tools to avoid warning spam when building dylibs.
Disable visibility warnings when building MoltenVKShaderConverter
in Release mode from external libraries built in Debug mode.
Always use -Xlinker -w option when creating dylibs to disable visibility warnings.
Add SPIRVToMSLConverterOptions::platform to track platform. Default to build platform.
Update default SPIRVToMSLConverterOptions MSL version to 2.1.
MoltenVKShaderConverter test MSL compilation use same MSL version as conversion.
Default min perf tracking value to 0.0.
SPIRVToMSLConverter.h reference spirv.hpp via SPIRV-Cross framework.
