Doing that in the signal IOCTL is probably a bit overkill since it is used 
quite often during the lifetime of the queue.

We can't add it to the userq manager creation because that is often done by 
X/Wayland instead of the final application, but I think we can just add it to 
the queue creation.

That should always be done in the process which is going to use the queue.


True i also thought of it and it is definitely a overkill, that's why i 
thought to have a check if its not NULL then set it else just pass it. 
But i agree during queue create time also it is fine. Let me send the 
new patch with queue create time.

r = amdgpu_userq_fence_read_wptr(adev, queue, &wptr);
if (r)
goto put_queue;

[PATCH] drm/amdgpu/userq: update the vm task info during signal ioctl

2026-05-12 Thread Sunil Khatri
Pagefaults does not have process information correctly populated
as vm->task is not set during vm_init but should be updated while
real submission. So setting that up during signal_ioctl to get
the correct submission process details.
