something interesting, I guess apple doesn't report the device/vendor.

    "Apple": {
      "id": "0x106b",

      "_comment": [
        "Apple GPUs do not report a DeviceID via the Metal API, and as such the typical device",
        "pattern matching does not work for them. The recommended approach is to find the highest",
        "supported 'common' family supported and report it as the architecture.",
        "Examples: 'common-1', 'common-3'",
        "https://developer.apple.com/documentation/metal/gpu_devices_and_work_submission/detecting_gpu_features_and_metal_software_versions"
      ]

I don't think it's a problem. Just do what Metal's layer says and just pass the single device.

I don't mind to add these undefs to the interface.

not sure how this will work in practice.

@dzhdanNV just an observation you nearly have a pure C interface any reason for the C++ code to abstract across that. you can also just union a bunch of stuff together for dx12/dx11/vulkan/metal. You also have all this logic to build tables of functions etc ... avoid having to use a C++ so it should be easier to distribute. I guess you could just access that data based on the api.

struct CmdBuffer {
   union {
      struct {...}dx11;
      struct {...}dx12;
      struct {...}metal;
   };
}

struct NriDevice {
   union {
      struct {...}dx11;
      struct {...}dx12;
      struct {...}metal;
   };
   int (*Method1)(NriDevice*...);
}

indexBufferOffset: m_CurrentIndexCmd.m_Offset];
}
void CommandBufferMTL::DrawIndirect(const Buffer& buffer, uint64_t offset, uint32_t drawNum, uint32_t stride, const Buffer* countBuffer, uint64_t countBufferOffset) {}
void CommandBufferMTL::DrawIndexedIndirect(const Buffer& buffer, uint64_t offset, uint32_t drawNum, uint32_t stride, const Buffer* countBuffer, uint64_t countBufferOffset) {}

Ping me when you're done with the base implementation, I'll try to get samples to work.

Also, argument buffers can be used to emulate root constants/push constants. But yes, you can also use it for count buffers

feel free to jump in if you know what to do, you can drop me a PR and i can merge it. still looking around at the metal docs and trying to roughly get something together, will take quite a bit there is a lot here to cover.

not sure how these will fit together i only know about encoder once the pipeline is set. the attachment is know only with BeginRendering

I have something rough for this CommandBufferMTL. hopefully I can get something rough.
