v1 -> v2:
- Rebased on master.
The Generic Root Port behaves the same as the
Intel's IOH device with id 3420, without having
Intel specific attributes.
The device has two purposes:
(1) Can be used on both X86 and ARM machines.
(2) It will allow us to tweak the behaviour
(e.g add vendor-specific PCI capabilities)
- something that obviously cannot be done
on a known device.
Patch 1/3: Introduce a base class for Root Ports - most of the code
is migrated from IOH3420 implementation.
Patch 2/3: Derives the IOH3420 from the new base class
Patch 3/3: Introduces the generic Root Port.
Tested with Linux and Windows guests only on x86 hosts.
I tested this both on x86/q35 (Debian guest) and on
aarch64/virt (Fedora guest) very briefly, eg. started
the guest, performed some network I/O and shut it down.
It seems to be working fine :)
Thanks for testing it! A tested-by tag would be appreciated for the next
version :)
