Question: xen + vhost user

2024-06-30 Thread Peng Fan

Hi All,

I am trying to enable vhost user input with xen hypervisor on i.MX95, using qemu
vhost-user-input. But meet " Invalid vring_addr message ". My xen domu cfg:

'-chardev', 'socket,path=/tmp/input.sock,id=mouse0',
'-device', 'vhost-user-input-pci,chardev=mouse0',

Anyone knows what missing?

Partial error log:
 Vhost user message 
Request: VHOST_USER_SET_VRING_ADDR (9)
Flags:   0x1
Size:40
vhost_vring_addr:

log_guest_addr:   0x444714c0
Setting virtq addresses:
vring_desc  at (nil)
vring_used  at (nil)
vring_avail at (nil)
