Subject: [PATCH V7 0/4] PCI: Add support for preserving boot configuration
Date: Wed, 8 May 2024 23:11:34 +0530 [thread overview]
Message-ID: <20240508174138.3630283-1-vidyas@nvidia.com> (raw)
Add support for preserving the boot configuration done by the
platform firmware per host bridge basis, based on the presence of
'linux,pci-probe-only' property in the respective PCI host bridge
device-tree node. It also unifies the ACPI and DT based boot flows
in this regard.
This patch series is a complete version of the incomplete series
( https://lore.kernel.org/linux-pci/20240421190914.374399-1-helgaas@kernel.org/ )
posted by Bjorn which in turn was an attempted split work of the single V6 patch
( https://lore.kernel.org/linux-pci/20240418174043.3750240-1-vidyas@nvidia.com/ )
posted by me.

PCI: Unify ACPI and DT 'preserve config' support
PCI: Use preserve_config in place of pci_flags
