This is the Intel ACPI Component Architecture, Intel's reference
|
|
implementation of the core operating system ACPI support. The
|
|
portion in the Osd/ subdirectory is provided by the oprerating
|
|
system as the glue between the OS and the ACPICA.
|
|
|
|
Please, do not import an updated ACPI CA snapshot from Intel unless
|
|
you absolutely know what you're doing -- The Intel directory layout
|
|
changes from release to release, and we must munge it (by hand) into
|
|
something sane that we can use.
|
|
|
|
The routines that the operating system must provide are documented
|
|
in the following document:

|
Machine-dependent code must provide the following routines for Osd:
|
|
|
|
ACPI_STATUS acpi_md_OsInitialize(void);
|
|
ACPI_STATUS acpi_md_OsTerminate(void);
|
|
ACPI_STATUS acpi_md_OsGetRootPointer(UINT32 Flags,
|
|
ACPI_PHYSICAL_ADDRESS *PhysicalAddress);
|
|
|
|
UINT8 acpi_md_OsIn8(ACPI_IO_ADDRESS InPort);
|
|
UINT16 acpi_md_OsIn16(ACPI_IO_ADDRESS InPort);
|
|
UINT32 acpi_md_OsIn32(ACPI_IO_ADDRESS InPort);
|
|
|
|
void acpi_md_OsOut8(ACPI_IO_ADDRESS OutPort, UINT8 Value);
|
|
void acpi_md_OsOut16(ACPI_IO_ADDRESS OutPort, UINT16 Value);
|
|
void acpi_md_OsOut32(ACPI_IO_ADDRESS OutPort, UINT32 Value);
|
|
|
|
ACPI_STATUS acpi_md_OsInstallInterruptHandler(UINT32 InterruptNumber,
|
|
OSD_HANDLER ServiceRoutine, void *Context, void **cookiep);
|
|
void acpi_md_OsRemoveInterruptHandler(void *cookie);
|
|
|
|
ACPI_STATUS acpi_md_OsMapMemory(ACPI_PHYSICAL_ADDRESS PhysicalAddress,
|
|
UINT32 Length, void **LogicalAddress);
|
|
void acpi_md_OsUnmapMemory(void *LogicalAddress, UINT32 Length);
|
|
ACPI_STATUS acpi_md_OsGetPhysicalAddress(void *LogicalAddress,
|
|
ACPI_PHYSICAL_ADDRESS *PhysicalAddress);
|
|
|
|
BOOLEAN acpi_md_OsReadable(void *Pointer, UINT32 Length);
|
|
BOOLEAN acpi_md_OsWritable(void *Pointer, UINT32 Length);
