Add MVKPhysicalDeviceMetalFeatures::counterSamplingPoints
to track platform availability of GPU counters.
MVKPhysicalDevice creates and manages MTLCounterSets and checks for and enables
flags within MVKPhysicalDeviceMetalFeatures::counterSamplingPoints.
Add abstract MVKGPUCounterQueryPool class as parent of MVKTimestampQueryPool
and MVKPipelineStatisticsQueryPool concrete classes and refactor access to host
and command copy tracking data to allow extraction from MTLCounterSampleBuffer.
MVKTimestampQueryPool uses MTLCounterSampleBuffer if supported, otherwise reverts
to using host data for timestamps.
MVKCommandEncoder encodes Vulkan timestamp commands either as Metal staged or
command timestamps, depending on whether the GPU is tile-based or immediate-mode.
For Metal stage counters, we use a light-weight dummy BLIT encoder to mark
timestamp commands executed in the previous Metal encoding pass.
Add MVKDevice::getDummyBlitMTLBuffer() to supply a dummy single-byte buffer that
can be used by a stand-alone MTLBlitCommandEncoder as dummy work to mark timestamps.
If alpha-to-coverage is enabled, we must enable the fragment shader first color output,
even without a color attachment present or in use, so that coverage can be calculated.
VK_FORMAT_E5B9G9R9_UFLOAT_PACK32 on macOS Apple Silicon.
On Apple Silicon (iOS/tvOs/macOS M1), format VK_FORMAT_E5B9G9R9_UFLOAT_PACK32
is fully supported as a color attachment except that format components cannot
be individually write-enabled. All components must either be write-enabled or
write-disabled together. This is causing several hundred Vulkan CTS blending
tests to fail on M1. The least intrusive behavioural change to allow the CTS
tests to report Not Supported instead, is to disable blending for this format.
Depth/stencil attachments that are also sampled might have an artificially forced
swizzled texture view. The original unswizzled texture must be used for attachments.
Add MVKImageViewPlane::getUnswizzledMTLTexture().
Move MVKImageView::validateSwizzledMTLPixelFormat() to
MVKImageViewPlane::initSwizzledMTLPixelFormat(), make it non-static, and use
instance member content instead of passing all the data as function arguments.
The same set of CTS tests either fails or passes on different GPUs
based on whether or not we adjust float clear colors by one ULP.
Add MVKFloatRounding enum.
Add MVKPhysicalDeviceMetalFeatures::clearColorFloatRounding.
Disable ULP adjustment for clear colors on Apple Silicon.
For consistency and to simplify bookkeepping, calculate
clear color ULP adjustment from bit width of format component.
Update MoltenVK version to 1.1.5.
Update VK_MVK_MOLTENVK_SPEC_VERSION to 32.
MVKOcclusionQueryCommandEncoderState::beginOcclusionQuery() check for visibility
buffer exhaustion, and if needed, log an error and disable further visibility
tracking for the remainder of the current MTLCommandBuffer.
Create visibility buffer if needed during MVKCommandEncoder::beginMetalRenderPass.
Simplify MVKCommandEncodingContext to PODS.
across separate render encoders within a single Metal command buffer (Vulkan submit).
Add MVKCommandEncodingContext to track information across multiple
MVKCommandEncoders, and use it to track temporary visibility buffer and offset.
Add support for more than one temporary visibility buffer per MTLCommandBuffer
when current temporary visibility buffer is exhausted.
offsets across separate render encoders within a single Vulkan command buffer.
Monotonically increase the offset into the temporary visibility buffer
after each query in a MVKCommandEncoder (ie- Vulkan command buffer).
e1ac50c0 marks temporary buffers as volatile, but it only mlocks() them for the duration
of memcpy() of initial data, leaving Metal runtime a window to snatch it before the buffer
is no longer in use. Simply putting the munlock() in a completion handler raises questions
about possible edge cases where multiple, non page-aligned allocations are live.
This patch fixes it by keeping the whole buffer non-volatile while is supports any active
allocations.
Fixes rendering issues in Sekiro: Shadows Die Twice menus.
