Do not use MTLEvent for VkSemaphore under Rosetta2.
Remove compile test for MVK_MACOS_APPLE_SILICON and MVK_APPLE_SILICON when testing
for Apple GPU families, to allow x86 builds to test for Apple GPU under Rosetta2.
Simplify identifying M1 GPU. All M1 SoCs currently support the A14 (Apple7) GPU.
Support compiling MSL 2.4 in runtime pipelines and MoltenVKShaderConverterTool.
Fix issue where MSL 2.3 only available on Apple Silicon, even on macOS.
Update to latest SPIRV-Cross (unrelated to Rosetta2).
Add build environment variable MVK_HIDE_VULKAN_SYMBOLS. to allow MoltenVK
to be built with static Vulkan API symbols hidden, to avoid library linking
conflicts when bound to a Vulkan Loader that also exports identical symbols.
The default value of MVK_HIDE_VULKAN_SYMBOLS is 0,
meaning Vulkan static symbols are exposed by default.
Add MVK_PUBLIC_VULKAN_SYMBOL directive to mark each Vulkan call symbols
for exporting or hiding.
Update the MoltenVK Xcode project to add the MVK_HIDE_VULKAN_SYMBOLS build
setting, and set the ENABLE_TESTABILITY build setting to NO, because it
conflicts with stripping symbols.
Update MoltenVK version to 1.1.7.
Metal does not provide direct support for BC1_RGB formats
(VK_FORMAT_BC1_RGB_UNORM_BLOCK & VK_FORMAT_BC1_RGB_SRGB_BLOCK).
We have been faking it by mapping these Vulkan formats to Metal
formats containing alpha (MTLPixelFormatBC7_RGBAUnorm &
MTLPixelFormatBC7_RGBAUnorm_sRGB, respectively),
and advertising support for BC1_RGB formats.
However, this triggers CTS failures, because the BC1_RGBA formats can return
an alpha value of 0.0 when constructed that way, whereas the BC1_RGB formats
always expect 1.0 (opaque) to be returned.
This change moves to indirect support for BC1_RGB formats. They will still
be covered by MTLPixelFormatBC7_RGBAUnorm & MTLPixelFormatBC7_RGBAUnorm_sRGB,
and will effectively work (except transparency), but are no longer advertised
through physical device format and image format queries.
Dynamic pipeline state set before the pipeline is set was reading
dynamic flags from previous pipeline. This is fixed here by accepting
the dynamic state, but deferring the decision to use either dynamic
or static state until the pipeline is encoded.
An MVKImageView that renders to only one layer of a multilayer MVKImage
is not performing multilayer-rendering. Only validate multilayer-rendering
when it is definitely requested in an MVKImageView, instead of presuming
when a multilayer MVKImage is marked for rendering.
Check that appropriate GPU counter set is supported on
the device before creating GPU counter sample buffer.
Don't attempt to timestamp using GPU counters unless
a GPU sample counter buffer has been created.
Support maximum point primitive size of 511.
Update to latest SPIRV-Cross version to add support
for OpSpecConstantOp ops OpQuantizeToF16 and OpSRem.
Update MoltenVK version to 1.1.6.
MTLMaxBlitPassSampleBuffers was available in Xcode 12 and had a value of 4.
According to Apple, the definition will be removed from the API in Xcode 13.
For now, assume a value of 1, until we can accurately determine the
appropriate value per platform.
MSL: Support row-major transpose when storing matrix from constant RHS matrix.
MSL: Fix casting in constant expressions with different sizes.
MSL: Fix duplicate gl_Position outputs when gl_Position defined but unused.
Apple GPUs do not support rendering/writing to an attachment and then reading
from that attachment within a single Metal renderpass. On Apple Silicon, restart
the Metal renderpass if an input attachment is cleared inside renderpass.
Don't clear render area when restarting Metal renderpass, as it should not occur,
and itself causes a recursive loop restarting the renderpass as a result.
Add MVKCommandUse::kMVKCommandUseRestartSubpass.
MVKCommandEncoder::beginMetalRenderPass() pass MVKCommandUse to help determine
Metal renderpass attachment load and clearing options.
A recent change for resolving color formats mistakenly
broke clearing depth and stencil formats.
Remove optionality of all function arguments in
MVKRenderPassAttachment::populateMTLRenderPassAttachmentDescriptor()
to avoid bad calls being masked by optional function arguments.
Add appropriate canResolveFormat values for all calls to that function.
