[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v5 12/21] acpi/hvmloader: Include file/paths adjustments
In prepearation to moving acpi sources into generally available
libacpi:
1. Pass IOAPIC/LAPIC/PCI mask values via struct acpi_config
2. Modify include files search paths to point to acpi directory
3. Macro-ise include file for build.c that defines various
utilities used by that file. Users of libacpi will be expected
to define this macro when compiling build.c

Changes in v5:
* Include <xen/hvm/hvm_info_table.h> in build.c

+BUILDING ACPI
-----------------
-Simply make is OK.
-# make
+Users of ACPI builder are expected to provide an include file that makes
available
+the following:
+* strncpy
+* printf
+* NULL
+* test_bit
+* offsetof
+When compiling build.c, the name of this include file should be given to
+compiler as -DLIBACPI_STDUTILS=\"<filename>\". See
tools/firmware/hvmloader/Makefile
+for an example.
Note on DSDT Table
