I have brutal DPC Latency on qemu, no matter if using pci-assign or
vfio-pci or without any passthrought,
my DPC Latency is like:
10000,500,8000,6000,800,300,12000,9000,700,2000,9000
and on native windows 7 is like:
20,30,20,50,20,30,20,20,30
I don't know how to fix it.
this matter for me because i are using USB Sound Card for my VMs,
and i get sound drop-outs every 0-4 secounds
