Subject: [PATCH v2 0/2] PCI: Init RCB from pci_configure_device and fix program_hpx_type2
Date: Wed, 21 Jan 2026 12:35:39 +0100	[thread overview]
Message-ID: <20260121113544.4163457-1-haakon.bugge@oracle.com> (raw)

This series add the initialization of the Link Control register's RCB
to pci_configure_rcb() called from pci_configure_device() and also
cleans up the incorrect program_hpx_type2():

1. It should only be called when we own the PCIe native hotplug and
   not the AER ownership
2. It should only manipulate the AER-bits

In addition, the second commit adds a warning if the _HPX type2
record attempts to modify the Link Control register.

Håkon Bugge (2):
  PCI: Initialize RCB from pci_configure_device
  PCI/ACPI: Confine program_hpx_type2 to the AER bits
