[PATCH 0/4] xen/uart: some fixes and improvements

Posted by Roger Pau Monne 1 week, 1 day ago

Hello,

First patch is a fix that otherwise prevents using the serial on some
(newish?) Intel AMT devices (at least the one I have).  Patches 2 and 3
are general improvements and cleanups.  Finally patch 4 adds support for
getting the serial configuration from ACPI SPCR table.

Thanks, Roger.

Roger Pau Monne (4):
  xen/uart: be more careful with changes to the PCI command register
  xen/uart: switch ns16550 to use pci_sbdf_t
  xen/uart: report an error if the device type is not supported
  xen/uart: enable parsing ACPI SPCR on x86
