framework from the ACPI tables.
Also implement acpi_intr_establish(), acpi_intr_disestablish() and
acpi_intr_string().
Needed for the upcoming HID over I2C support, proposed on tech-kern@
on Dec, 1.
- query the descriptor to get the interface version, needed to workaround
a bug in the BIOS/ACPI
- properly decode the event buffer in type/subtype, and handle multiple events
per handler call
- record some known type/subtype in a table, with associated actions.
Informations mostly from linux. Tested on a Dell 5480 laptop.
kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

acpi_resource_parse() with &acpi_resource_parse_ops_default prints
resouce info and newline. Found and tested on ThinkPad X21.
- Add PCI Extended Configuration Space support into x86.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
Currently the following extended capabilities are decoded:
- Advanced Error Reporting
- Virtual Channel
- Device Serial Number
- Power Budgeting
- Root Complex Link Declaration
- Root Complex Event Collector Association
- Access Control Services
- Alternative Routing-ID Interpretation
- Address Translation Services
- Single Root IO Virtualization
- Page Request
- TPH Requester
- Latency Tolerance Reporting
- Secondary PCI Express
- Process Address Space ID
- LN Requester
- L1 PM Substates
The following extended capabilities are not decoded yet:
- Root Complex Internal Link Control
- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization
- Multicast
- Resizable BAR
- Dynamic Power Allocation
- Protocol Multiplexing
- Downstream Port Containment
- Precision Time Management
- M-PCIe
- Function Reading Status Queueing
- Readiness Time Reporting
- Designated Vendor-Specific
