[Qemu-devel] MSI broken?

[Gerd Hoffmann]

 Hi,

What is the status if the recently merged MSI support?

I'm trying to use it to add msi support to the intel-hda driver (current 
wip patch attached).  Everything works fine up to the point where it 
comes to delivering the interrupt to the guest.  msi_notify pretends to 
signal the guest:

msi_notify:243 intel-hda:30 notify vector 0x0 address: 0xfee01008 data: 
0x4151

The guest never ever receives this interrupt though:

address@hidden ~]# grep hda /proc/interrupts
 43:          0   PCI-MSI-edge      hda_intel

Ideas anyone?

thanks,
  Gerd
