v3:
- Move common code to lib/fw_table.c
v2:
- Split out with CONFIG_ACPI_TABLES_LIB to be independent
- Fixed 0-day issues
- Change CDAT releveant names to prefix with cdat/CDAT instead of
acpi/ACPI. (Jonathan)
- Make table_header a union with cdat table header instead of
'acpi_table_header'. (Jonathan)
- Removed ACPI_SIG_CDAT, already defined.
Hi Rafael,
Please consider ack these patches. Dan can take these through the CXL tree. After
attempting to rename the cxl_ prefixes of functions and non ACPICA data structures
to something more common, it seems that significant amount of ACPI code would be
touched for the rename. For this series I left it alone in order to have the minimal
changes to ACPI code.
I've broken out the "cxl: Add support for QTG ID retrieval for CXL subsystem" [1]
series in order to make it more manageable. Here's the first part of the ACPI
changes. These changes are added to allow reuse of ACPI tables code to parse
the CDAT tables. While CDAT is not part of ACPI, the table structures are similar
to ACPI layouts that the code can be reused with some small modifications.
However, in order to be properly utilized by CXL users, the tables code needs
to be refactored out to be independent of ACPI. For example, a PPC BE host may
have CXL and does not have ACPI support. But it will have CDAT to read from
devices and switches. I have created CONFIG_ACPI_TABLES_LIB in order to allow
the common code to be independent. 0-day seems to be happy now for all the
different configs and archs.
1/4: Split out the common code from drivers/acpi/tables.c to lib/fw_table.c
2/4: Add CDAT support
3,4/4: These two are minor patches that has ACPICA impact. Has been merged into
the ACPICA git repo [3].
The whole series is at [2] for convenience.
