Subject: [PATCH V6 0/5] ECAM quirks handling for ARM64 platforms
Date: Fri, 9 Sep 2016 21:24:02 +0200 [thread overview]
Message-ID: <1473449047-10499-1-git-send-email-tn@semihalf.com> (raw)
Quirk handling relies on an idea of simple static array which contains
quirk enties. Each entry consists of identification information (IDs from
standard header of MCFG table) along with custom pci_ecam_ops structure and
configuration space resource structure. This way it is possible find
corresponding quirk entries and override pci_ecam_ops and PCI configuration
space regions.
As an example, the last 3 patches present quirk handling mechanism usage for
ThunderX.
v5 -> v6
- rebase against v4.8-rc5
- drop patch 1 form previous series
- keep pci_acpi_setup_ecam_mapping() in ARM64 arch directory
- move quirk code to pci_mcfg.c
- restrict quirk to override pci_ecam_ops and CFG resource structure
only, no init call any more
- split ThunderX quirks into the smaller chunks
- add ThunderX pass1.x silicon revision support
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
