Hi,
As discussed, it would be good to fix piixide driver when i440fx chipset
is used by default in qemu ("-M pc").
Currently we get "lost interrupt" messages appearing from rumpdisk and
the disk access is not working.
I tried compiling gnumach **without** --enable-apic and bypassing the
acpi translator startup. In this case, piixide driver works correctly.
I think there is some kind of disconnect between I/O APIC in qemu and
the PIIX3 IDE controller. (Maybe they cannot be used concurrently?)
Alternatively, if you really want to use -M pc default machine, you can
attach an ich9-ahci controller and connect the primary disk to this
controller as a SATA disk:
-drive id=disk,file=/path/to/disk.img,if=none \
-device ich9-ahci,id=ahci \
-device ide-hd,bus=ahci.0,drive=disk \
This works without specifying a -M option with acpi and rumpdisk with an
--enable-apic gnumach, by using an AHCI controller instead of a PIIX3
IDE controller.
In other news, we still have a bug with rumpdisk timing out on AHCI->wd0
on native controllers. I am not sure what causes this but I suspect
some kind of race condition between startup translators.
