@Teddy-Astie Is this patch already in the current kernel or do i need to manually apply it?

RE: Google Coral TPU PCIe Passthrough Woes
hey @andSmv @olivierlambert
I have a PCI coral TPU and have the same issue from this thread. It doesn't look like anyone confirmed if the patch is working.Anything I can do to help test here? I have just switched away from proxmox so would prefer to get it working in XCP
I'm currently on 8.3 and the alt kernel. But happy to test with whatever, I have some spare hardware to setup a dedicated test if needed.uname -a Linux xcp-long 4.19.316+1 #1 SMP Mon Aug 19 14:31:42 CEST 2024 x86_64 x86_64 x86_64 GNU/Linux
