Re: [PATCH] drm/amdgpu: unpack dma_fence_chain containers during sync

I can test some more tonight. I'll also try to prepare a standalone trace so you can observe the exact pattern being used on your end. Vulkan traces tend to be GPU and driver-specific. We'll use Mesa as the driver, but what GPU would be most convenient on your side for replaying? On our end I

Mhm, then I don't know what's going wrong here. Could be that the fence somehow ends up in a BO dependency. Pierre do you have some time for testing today? Or could you provide me some way to test this? Christian. Am 24.11.20 um 03:48 schrieb Pierre-Loup A. Griffais: I just built my
