Subject: [Patch v2 00/22] Improve ACPI resource parsing interfaces and enable IOAPIC hotplug
During enabling ACPI based IOAPIC hotplug, Thomas noticed some issues
in ACPI resource parsing interfaces. So this is an effort to improve them.
Patch 1 refines ACPICA resource descriptors, which has already been
merged into "git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git bleeding-edge"
Patch 2-12 improve ACPI resource parsing interfaces and also fixes some
bugs.
Patch 13-19 try to share the common data structure resource_list_entry
between PCI and ACPI. It may also be shared with PNP too.
Patch 20-22 enable ACPI based IOAPIC hotplug.
The patchset is based on v3.19-rc6+ and passed Fengguang's 0day test
suite. You may get it from:
https://github.com/jiangliu/linux.git acpires_v2
V1->V2:
1) Refine the way to share common code between address space and extended
address space.
2) Relax some checks to avoid regressions according to Rafael's suggestions.
3) Introduce struct resource_win to avoiding add extra parameter "offset"
to several interfaces.
4) Add patches to enable ACPI based IOAPIC hotplug, which has been reviwed
several rounds.
5) Rebase to v3.19-rc6+
Thanks,
Gerry
Jiang Liu (13):
ACPI: Fix a bug in parsing ACPI Memroy24 resource
ACPI: Normalize return value of resource parser functions
ACPI: Set flag IORESOURCE_UNSET for unassigned resources
ACPI: Enforce stricter checks for address space descriptors
ACPI: Return translation offset when parsing ACPI address space
resources
ACPI: Translate resource into master side address for bridge window
resources
ACPI: Add field offset to struct resource_list_entry
ACPI: Introduce helper function acpi_dev_filter_resource_type()
resources: Move struct resource_list_entry from ACPI into resource
core
PCI: Use common resource list management code instead of private
implementation
x86/PCI/ACPI: Use common ACPI resource interfaces to simplify
implementation
x86/PCI: Refine the way to release PCI IRQ resources
x86/irq, ACPI: Implement ACPI driver to support IOAPIC hotplug
Lv Zheng (1):
ACPICA: Resources: Provide common part for struct
acpi_resource_address structures.
Thomas Gleixner (7):
ACPI: Remove redundant check in function
acpi_dev_resource_address_space()
ACPI: Implement proper length checks for mem resources
ACPI: Use the length check for io resources as well
ACPI: Let the parser return false for disabled resources
ACPI: Unify the parsing of address_space and ext_address_space
ACPI: Move the window flag logic to the combined parser
ACPI: Add prefetch decoding to the address space parser
Yinghai Lu (1):
ACPI: Add interfaces to parse IOAPIC ID for IOAPIC hotplug
