Hi Jan,
Just tested with about the same kernel (and same hardware) on linux + kvm:
When i boot i see (on the host):
[ 1.341556] pcieport 0000:00:02.0: irq 31 for MSI/MSI-X
[ 1.341875] pcieport 0000:00:03.0: irq 32 for MSI/MSI-X
[ 1.342145] pcieport 0000:00:05.0: irq 33 for MSI/MSI-X
[ 1.342429] pcieport 0000:00:06.0: irq 34 for MSI/MSI-X
[ 1.342588] pcieport 0000:00:09.0: irq 35 for MSI/MSI-X
[ 1.342853] pcieport 0000:00:0a.0: irq 36 for MSI/MSI-X
[ 1.343125] pcieport 0000:00:0b.0: irq 37 for MSI/MSI-X
[ 1.343285] pcieport 0000:00:0c.0: irq 38 for MSI/MSI-X
[ 1.343434] pcieport 0000:00:0d.0: irq 39 for MSI/MSI-X
[ 1.343719] pcieport 0000:00:15.0: irq 40 for MSI/MSI-X
[ 1.343897] pcieport 0000:05:00.0: irq 41 for MSI/MSI-X
[ 1.344134] pcieport 0000:06:01.0: irq 42 for MSI/MSI-X
[ 1.344398] pcieport 0000:06:02.0: irq 44 for MSI/MSI-X
While the soundcard has still irq16.
Passing through 09:00.0 to a KVM guest (as primary passthrough since that works
with KVM) it works fine and after shutting down there is no "irq 16 nobody
cared".
So why would linux setup those irq/gsi's for the pcieport differently on Xen
and on
