The 5 1.2.2.2 fvdl portion in the Osd/ subdirectory is provided by the oprerating 6 1.2.2.2 fvdl system as the glue between the OS and the ACPICA. 7 1.2.2.2 fvdl 8 1.2.2.2 fvdl Please, do not import an updated ACPI CA snapshot from Intel unless 9 1.2.2.2 fvdl you absolutely know what you're doing -- The Intel directory layout 10 1.2.2.2 fvdl changes from release to release, and we must munge it (by hand) into 11 1.2.2.2 fvdl something sane that we can use. 12 1.2.2.2 fvdl 13 1.2.2.2 fvdl The routines that the operating system must provide are documented 14 1.2.2.2 fvdl in the following document: 15 1.2.2.2 fvdl 16 1.2.2.2 fvdl ACPI Component Architecture Programmer Reference 17 1.2.2.2 fvdl Intel Corp. 18 1.2.2.2 fvdl 19 1.2.2.2 fvdl Machine-dependent code must provide the following routines for Osd: 20 1.2.2.2 fvdl 21 1.2.2.2 fvdl ACPI_STATUS acpi_md_OsInitialize(void); 22 1.2.2.2 fvdl ACPI_STATUS acpi_md_OsTerminate(void); 23 1.2.2.2 fvdl ACPI_STATUS acpi_md_OsGetRootPointer(UINT32 Flags, 24 1.2.2.2 fvdl ACPI_PHYSICAL_ADDRESS *PhysicalAddress); 25 1.2.2.2 fvdl 26 1.2.2.2 fvdl UINT8 acpi_md_OsIn8(ACPI_IO_ADDRESS InPort); 27 1.2.2.2 fvdl UINT16 acpi_md_OsIn16(ACPI_IO_ADDRESS InPort); 28 1.2.2.2 fvdl UINT32 acpi_md_OsIn32(ACPI_IO_ADDRESS InPort); 29 1.2.2.2 fvdl 30 1.2.2.2 fvdl void acpi_md_OsOut8(ACPI_IO_ADDRESS OutPort, UINT8 Value); 31 1.2.2.2 fvdl void acpi_md_OsOut16(ACPI_IO_ADDRESS OutPort, UINT16 Value); 32 1.2.2.2 fvdl void acpi_md_OsOut32(ACPI_IO_ADDRESS OutPort, UINT32 Value); 33 1.2.2.2 fvdl 34 1.2.2.2 fvdl ACPI_STATUS acpi_md_OsInstallInterruptHandler(UINT32 InterruptNumber, 35 1.2.2.2 fvdl OSD_HANDLER ServiceRoutine, void *Context, void **cookiep); 36 1.2.2.2 fvdl void acpi_md_OsRemoveInterruptHandler(void *cookie); 37 1.2.2.2 fvdl 38 1.2.2.2 fvdl ACPI_STATUS acpi_md_OsMapMemory(ACPI_PHYSICAL_ADDRESS PhysicalAddress, 39 1.2.2.2 fvdl UINT32 Length, void **LogicalAddress); 40 1.2.2.2 fvdl void acpi_md_OsUnmapMemory(void *LogicalAddress, UINT32 Length); 41 1.2.2.2 fvdl ACPI_STATUS acpi_md_OsGetPhysicalAddress(void *LogicalAddress, 42 1.2.2.2 fvdl ACPI_PHYSICAL_ADDRESS *PhysicalAddress); 43 1.2.2.2 fvdl 44 1.2.2.2 fvdl BOOLEAN acpi_md_OsReadable(void *Pointer, UINT32 Length); 45 1.2.2.2 fvdl BOOLEAN acpi_md_OsWritable(void *Pointer, UINT32 Length); 46 1.2.2.2 fvdl 47 1.2.2.2 fvdl -- Jason R.
