Hello,
This patch series attempts to fix the regressions caused by 75cc460a1b
('xen/pci: detect when BARs are not suitably positioned') and the last
patch relaxes the check done when attempting to write to BARs with
memory decoding enabled.
I consider all of them bug fixes, albeit the last patch is not fixing a
regression (since vPCI code has always behaved this way).
Thanks, Roger.
Roger Pau Monne (5):
vpci: don't assume that vpci per-device data exists unconditionally
vpci/msix: remove from table list on detach
vpci: introduce a local vpci_bar variable to modify_decoding()
pci: do not disable memory decoding for devices
vpci: refuse BAR writes only if the BAR is mapped
