Subject: [PATCH pciutils 0/4] Support for PCI_FILL_PARENT
Date: Fri, 21 Jan 2022 15:22:54 +0100 [thread overview]
Message-ID: <20220121142258.28170-1-pali@kernel.org> (raw)
Extend libpci API with a new option PCI_FILL_PARENT to fill parent
device for the current enumerated device. This can be useful in
situation when non-complaint PCI-to-PCI bridge-like device with Type 0
header is present in the system and behind this bridge are either
endpoint devices or another non-compliant bridges. This applies e.g.
for notoriously broken Galileo and Marvell PCI and PCIe devices.
lspci can will use PCI_FILL_PARENT information from the system if
config space does not provide enough information to build topology.
Pali Rohár (4):
libpci: Add new option PCI_FILL_PARENT
libpci: sysfs: Implement support for PCI_FILL_PARENT
lspci: Build tree based on PCI_FILL_PARENT information
lspci: Do not show -[00]- bus in tree output
