[RFC Patch 00/19] Improve ACPI resource parsing interfaces and data structures

From: Jiang Liu
Date: Wed Jan 07 2015 - 21:30:20 EST


During enabling ACPI based IOAPIC hotplug, Thomas noticed some issues
in ACPI resource parsing interfaces. So this is an effort to improve them.

Patch 1-12 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.

The patchset is based on v3.19-rc3 and you may get it from:

Jiang Liu (11):
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

Thomas Gleixner (8):
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: Provide union for address_space64 and ext_address_space64
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
