The 51.1Sthorpejportion in the Osd/ subdirectory is provided by the oprerating 61.1Sthorpejsystem as the glue between the OS and the ACPICA. 71.1Sthorpej 81.1SthorpejPlease, do not import an updated ACPI CA snapshot from Intel unless 91.1Sthorpejyou absolutely know what you're doing -- The Intel directory layout 101.1Sthorpejchanges from release to release, and we must munge it (by hand) into 111.1Sthorpejsomething sane that we can use. 121.1Sthorpej 131.1SthorpejThe routines that the operating system must provide are documented 141.1Sthorpejin the following document: 151.1Sthorpej 161.1Sthorpej ACPI Component Architecture Programmer Reference 171.1Sthorpej Intel Corp. 181.3Sperry 191.3SperryCopies of the document may be retrieved from: 201.3Sperry 211.3Sperry http://developer.intel.com/technology/iapc/acpi/downloads.htm 221.1Sthorpej 231.1SthorpejMachine-dependent code must provide the following routines for Osd: 241.1Sthorpej 251.1SthorpejACPI_STATUS acpi_md_OsInitialize(void); 261.1SthorpejACPI_STATUS acpi_md_OsTerminate(void); 271.1SthorpejACPI_STATUS acpi_md_OsGetRootPointer(UINT32 Flags, 281.1Sthorpej ACPI_PHYSICAL_ADDRESS *PhysicalAddress); 291.1Sthorpej 301.1SthorpejUINT8 acpi_md_OsIn8(ACPI_IO_ADDRESS InPort); 311.1SthorpejUINT16 acpi_md_OsIn16(ACPI_IO_ADDRESS InPort); 321.1SthorpejUINT32 acpi_md_OsIn32(ACPI_IO_ADDRESS InPort); 331.1Sthorpej 341.1Sthorpejvoid acpi_md_OsOut8(ACPI_IO_ADDRESS OutPort, UINT8 Value); 351.1Sthorpejvoid acpi_md_OsOut16(ACPI_IO_ADDRESS OutPort, UINT16 Value); 361.1Sthorpejvoid acpi_md_OsOut32(ACPI_IO_ADDRESS OutPort, UINT32 Value); 371.1Sthorpej 381.1SthorpejACPI_STATUS acpi_md_OsInstallInterruptHandler(UINT32 InterruptNumber, 391.1Sthorpej OSD_HANDLER ServiceRoutine, void *Context, void **cookiep); 401.1Sthorpejvoid acpi_md_OsRemoveInterruptHandler(void *cookie); 411.1Sthorpej 421.1SthorpejACPI_STATUS acpi_md_OsMapMemory(ACPI_PHYSICAL_ADDRESS PhysicalAddress, 431.1Sthorpej UINT32 Length, void **LogicalAddress); 441.1Sthorpejvoid acpi_md_OsUnmapMemory(void *LogicalAddress, UINT32 Length); 451.1SthorpejACPI_STATUS acpi_md_OsGetPhysicalAddress(void *LogicalAddress, 461.1Sthorpej ACPI_PHYSICAL_ADDRESS *PhysicalAddress); 471.1Sthorpej 481.1SthorpejBOOLEAN acpi_md_OsReadable(void *Pointer, UINT32 Length); 491.1SthorpejBOOLEAN acpi_md_OsWritable(void *Pointer, UINT32 Length); 501.1Sthorpej 511.1Sthorpej -- Jason R.
