Subject: [PATCH v4 0/9] PCI: MMCONFIG clean up
Date: Wed, 11 Mar 2015 15:12:40 +0100 [thread overview]
Message-ID: <1426083169-8698-1-git-send-email-tomasz.nowicki@linaro.org> (raw)
MCFG ACPI table and PCI ECAM standard have no arch dependencies so it can be
used across all architectures. Currently MMCONFIG related code resides in
arch/x86 directories. This patch set is going to isolate non-architecture
specific code and make it accessible for all architectures.
v3 -> v4 changes:
- bug fixes after kbuild test robot report
- add asm/io.h header for ecam.c
- rename mmcfg -> ecam for drivers/xen/pci.c and arch/x86/pci/numachip.c
- rework Kconfig logic
v2 -> v3 changes:
- rebase patch set v2 to v4.0-rc1
v1 -> v2 changes:
- use generic readb/readw etc. accessors instead of AMD Fam10h workaround
- separate ACPI and ECAM code
- improve ECAM code naming
Tomasz Nowicki (9):
x86, pci: Clean up comment about buggy MMIO config space access for
AMD Fam10h CPUs.
x86, pci: Abstract PCI config accessors and use AMD Fam10h workaround
exclusively.
x86, pci: Reorder logic of pci_mmconfig_insert() function
x86, pci, acpi: Move arch-agnostic MMCONFIG (aka ECAM) and ACPI code
out of arch/x86/ directory
pci, acpi, mcfg: Provide generic implementation of MCFG code
initialization.
x86, pci: mmconfig_{32,64}.c code refactoring - remove code
duplication.
x86, pci, ecam: mmconfig_64.c becomes default implementation for ECAM
driver.
pci, acpi, mcfg: Share ACPI PCI config space accessors.
pci, ecam: Improve naming for ecam.c content and areas where it is
used.
