      I have a pretty good experience with multi gpu programming in D3D12. Now looking at Vulkan, although there are a few similarities, I cannot wrap my head around a few things due to the extremely sparse documentation (typical Khronos...)
      In D3D12 -> You create a resource on GPU0 that is visible to GPU1 by setting the VisibleNodeMask to (00000011 where last two bits set means its visible to GPU0 and GPU1)
      In Vulkan - I can see there is the VkBindImageMemoryDeviceGroupInfoKHR struct which you add to the pNext chain of VkBindImageMemoryInfoKHR and then call vkBindImageMemory2KHR. You also set the device indices which I assume is the same as the VisibleNodeMask except instead of a mask it is an array of indices. Till now it's fine.
      Let's look at a typical SFR scenario:  Render left eye using GPU0 and right eye using GPU1
      You have two textures. pTextureLeft is exclusive to GPU0 and pTextureRight is created on GPU1 but is visible to GPU0 so it can be sampled from GPU0 when we want to draw it to the swapchain. This is in the D3D12 world. How do I map this in Vulkan? Do I just set the device indices for pTextureRight as { 0, 1 }
      Now comes the command buffer submission part that is even more confusing.
      There is the struct VkDeviceGroupCommandBufferBeginInfoKHR. It accepts a device mask which I understand is similar to creating a command list with a certain NodeMask in D3D12.
      So for GPU1 -> Since I am only rendering to the pTextureRight, I need to set the device mask as 2? (00000010)
      For GPU0 -> Since I only render to pTextureLeft and finally sample pTextureLeft and pTextureRight to render to the swap chain, I need to set the device mask as 1? (00000001)
      The same applies to VkDeviceGroupSubmitInfoKHR?
      Now the fun part is it does not work  . Both command buffers render to the textures correctly. I verified this by reading back the textures and storing as png. The left texture is sampled correctly in the final composite pass. But I get a black in the area where the right texture should appear. Is there something that I am missing in this? Here is a code snippet too
      void Init() { RenderTargetInfo info = {}; info.pDeviceIndices = { 0, 0 }; CreateRenderTarget(&info, &pTextureLeft); // Need to share this on both GPUs info.pDeviceIndices = { 0, 1 }; CreateRenderTarget(&info, &pTextureRight); } void DrawEye(CommandBuffer* pCmd, uint32_t eye) { // Do the draw // Begin with device mask depending on eye pCmd->Open((1 << eye)); // If eye is 0, we need to do some extra work to composite pTextureRight and pTextureLeft if (eye == 0) { DrawTexture(0, 0, width * 0.5, height, pTextureLeft); DrawTexture(width * 0.5, 0, width * 0.5, height, pTextureRight); } // Submit to the correct GPU pQueue->Submit(pCmd, (1 << eye)); } void Draw() { DrawEye(pRightCmd, 1); DrawEye(pLeftCmd, 0); }

      Hi,
      I finally managed to get the DX11 emulating Vulkan device working but everything is flipped vertically now because Vulkan has a different clipping space. What are the best practices out there to keep these implementation consistent? I tried using a vertically flipped viewport, and while it works on Nvidia 1050, the Vulkan debug layer is throwing error messages that this is not supported in the spec so it might not work on others. There is also the possibility to flip the clip scpace position Y coordinate before writing out with vertex shader, but that requires changing and recompiling every shader. I could also bake it into the camera projection matrices, though I want to avoid that because then I need to track down for the whole engine where I upload matrices... Any chance of an easy extension or something? If not, I will probably go with changing the vertex shaders.

      I publishing for manufacturing our ray tracing engines and products on graphics API (C++, Vulkan API, GLSL460, SPIR-V): https://github.com/world8th/satellite-oem
      For end users I have no more products or test products. Also, have one simple gltf viewer example (only source code).
      In 2016 year had idea for replacement of screen space reflections, but in 2018 we resolved to finally re-profile project as "basis of render engine". In Q3 of 2017 year finally merged to Vulkan API.

      vkQueuePresentKHR is busy waiting - ie. wasting all the CPU cycles while waiting for vsync. Expected, sane, behavior would of course be akin to Sleep(0) till it can finish.
      Windows 7, GeForce GTX 660.
      Is this a common problem? Is there anything i can do to make it behave properly?

      I am working on reusing as many command buffers as I can by pre-recording them at load time. This gives a significant boost on CPU although now I cannot get the GPU timestamps since there is no way to read back. I Map the readback buffer before and Unmap it after reading is done. Does this mean I need a persistently mapped readback buffer?
      void Init() { beginCmd(cmd); cmdBeginQuery(cmd); // Do a bunch of stuff cmdEndQuery(cmd); endCmd(cmd); } void Draw() { CommandBuffer* cmd = commands[frameIdx]; submit(cmd); } The begin and end query do exactly what the names say.

Vulkan Support on Fermi

Hello,

 

Somewhere around September 2016 I worked with Vulkan on my NVIDIA GTX 570.

 

I somehow got it working, the problem was with vkEnumeratePhysicalDevices returning null.

 

Now I'm trying to continue my work and I run into the same problem. I've updated my drivers and double-checked everything. 

Today I've read that Fermi is not supported by Vulkan. But I 100% had it working a couple months ago. I'm lost.

 

What's changed since then is,

- I've moved to Visual Studio 2015 from 2013 and

- probably (not sure here) to Win10 from Win7. 

 

Does anyone have a clue how I could have done this before? Thanks.

IIRC with nVidia drivers the supported hardware compatibility checks weren't there at first, people reported creating contexts on Fermi (and other cards IIRC), but no one could do anything with it (I think it reported no supported texture formats or something).

 

After a few updates they patched in better checks for compatible hardware, thus why it wont work anymore.

 

They backed out from supporting Vulkan in Fermi GPUs, a while ago just right after Vulkan's official release, so that wont happen. Representative in the forums say something along the lines that the hardware could support it, but the dev time required wasnt worthwhile given its market share at the time (it sounded like BS since GTX560 and GTX570 were one of the most popular GPUs in Steam for example, who knows).

 

I had a GTX560 Ti, so bought an used GTX680 instead.

I'm out of luck then. Looks like I have to make an upgrade a bit earlier than expected.

 

 Thanks man.
