Example-specific fixes for: MoltenVK config, OpenMP build, UBO size alignment, descriptorindexing memory bounds error

2

This is a set of example-specific fixes: 1. Set MoltenVK configuration for descriptorindexing (enable Metal argument buffers for descriptor indexing on macOS, not available on iOS), oit (use `VK_IMAGE_TILING_LINEAR` vs....

I have been meaning to post these changes for a while, but am finally getting around to it now. They were developed for use in [RBDoom3BFG](https://github.com/RobertBeckebans/RBDOOM-3-BFG) and run on all...

Question: Guidance re MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS option

2

Are there any docs that provide performance guidance on the use of the `MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS` option? Up to this point I have been using the setting `MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS_DESCRIPTOR_INDEXING` based on the assumption...

Add updated iOS App support to the Vulkan examples

This PR depends on and includes #1117 due to those dependencies - only the final commits here are new. However, I am submitting this as a separate PR since I...

--data-path command line option not working

1

It appears the `--data-path` command line option is not hooked up inside the code. I can successfully run the samples via the command line when my working dir is the...

This PR addresses the concerns raised in #1097: 1. Optimizes compute-to-compute barriers so that write-to-read memory barriers are only applied to the buffer being written to. The read buffer does...

Set proper VkPhysicalDeviceSubgroupSizeControlProperties::minSubgroupSize for AMD RX6600 device

5

A minor issue, but the `minSubgroupSize` should probably be set to 32 for the AMD RX6600 (DeviceId 0x73FF) which is supported by macOS as of Monterey. As you state in...

Should Metal Argument Buffers be disabled by default on iOS Simulator?

3

The official Khronos _timeline_semaphore_ sample fails on iOS when running against MoltenVK 1.2.10. Previous versions (up to SDK 1.3.283 / MoltenVK 1.2.9) worked properly. Same test using MoltenVK 1.2.10 on...

Does the new Argument Buffer code support the iOS Simulator?

1

Kudos on the new argument buffer code. I have tested this on macOS (Ventura 13.6.6) and iOS (latest iOS 17.5.1 on iPhone 15) with the _descriptor indexing sample_ in Sascha...

fragmentShaderBarycentric reports as true without complete SPIR-V to MSL support

1

When testing the **fragment_shader_barycentric** sample from the official Khronos Vulkan Sample repository (https://github.com/KhronosGroup/Vulkan-Samples), I receive the following errors: _[mvk-error] SPIR-V to MSL conversion error: Cannot declare both BaryCoordNV and BaryCoordNoPerspNV...
