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:
[r...@localhost ~]# grep hda /proc/interrupts
43: 0 PCI-MSI-edge hda_intel
Ideas anyone?
Let's track it down futher.
Were acpi_mem_writel() and apic_send_msi() in hw/apic.c called or not?
No such function in my tree (savannah/master).
Looks like some bits needed for msi are not merged yet?
cheers,
Gerd
