| Subject | [RFC PATCH V5 0/5] ECAM quirks handling for ARM64 platforms |
| Message-ID | <s3StA-1Oa-15@gated-at.bofh.it> |
Quirk handling relies on an idea of matching MCFG OEM ID, TABLE ID and
revision (the ones from standard header of MCFG table).
Static array is used to keep quirk entries. Each entry consists of
mentioned MCFG IDs along with custom pci_ops structure and initialization call.
As an example, the last patch presents quirk handling mechanism usage for
ThunderX PEM driver.
v4 -> v5
- rebase against v4.8-rc1
- rework to exact MCFG OEM ID, TABLE ID, rev match
- use memcmp instead of strncmp
- no substring match
- fix typos and dmesg message
Tomasz Nowicki (5):
PCI: Embed pci_ecam_ops in pci_config_window structure
PCI/ACPI: Move ACPI ECAM mapping to generic MCFG driver
PCI: Check platform specific ECAM quirks
ARM64/PCI: Start using quirks handling for ACPI based PCI host
controller
PCI: thunder-pem: Support quirky configuration space access for ACPI
based PCI host controller
