2013-01-10ACPICA: Cleanup coding style to reduce differences between Linux and ACPICA.Lv Zheng1-1/+1
This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 314 lines of 20121018 divergence.diff. ACPICA core uses ()'s on return statements. This is a known and committed differences from Linux standard coding style. This patch cleans up the Linux side ACPICA code to use this codying style in order to reduce the source code differences between Linux and ACPICA.

2012-11-15ACPICA: Audit/update for ACPICA return macros and debug depth counterBob Moore1-1/+1
1) Ensure that all functions that use the various TRACE macros also use the appropriate ACPICA return macros. 2) Ensure that all normal return statements surround the return expression (value) with parens.

2012-07-17ACPICA: AcpiSrc: Fix some translation issues for Linux conversionBob Moore1-12/+12
Fixes issues like this: i_aSL -> iASL 00-7_f -> 00-7F local_fADT -> local_FADT execute_oSI -> execute_OSI Also, in function headers, the parameters are now translated to lower case (with underscores if necessary.)

2012-03-22ACPICA: Add acpi_os_physical_table_override interfaceBob Moore1-43/+50
This interface allows the host to override a table via a physical address, instead of the logical address required by acpi_os_table_override. This simplifies the host implementation. Initial implementation by Thomas Renninger. ACPICA implementation creates a single function for table overrides that attempts both a logical and a physical override.

2010-05-06ACPICA: Clarify/rename some root table descriptor fieldsBob Moore1-9/+10
Original fields were not very descriptive and led to maintenance problems. New fields should help to understand the existing code. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-04-20ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDTLin Ming1-0/+4
Some BIOS on Toshiba machines corrupt the DSDT, so add a new boot option acpi=copy_dsdt to workaround it. Add warning message to ask users to use this option if corrupt DSDT detected. Also build a DMI blacklist to check it and automatically copy DSDT. https://bugzilla.kernel.org/show_bug.cgi?id=14679 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-04-20ACPICA: Update DSDT copy/detection.Bob Moore1-11/+12
Move initialization of DSDT pointer. Emit address of DSDT in the dump of both table headers (good/bad DSDT). Now handles the case where the root table can be reallocated, which would invalidate the original pointer.

2010-04-20ACPICA: Add subsystem option to force copy of DSDT to local memoryLin Ming1-0/+35
Optionally copy the entire DSDT to local memory (instead of simply mapping it.) There are some BIOSs that corrupt or replace the original DSDT, creating the need for this option. Default is FALSE, do not copy the DSDT. https://bugzilla.kernel.org/show_bug.cgi?id=14679 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-04-20ACPICA: Add detection of corrupted/replaced DSDTLin Ming1-0/+38
This change adds support to detect a DSDT that has been corrupted and/or replaced from outside the OS (by firmware). This is typically catastrophic for the system, but has been seen on some machines. https://bugzilla.kernel.org/show_bug.cgi?id=14679 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-03-26ACPICA: Allow OS override of all ACPI tablesBob Moore1-13/+46
Previously, the table override mechanism was implemented for the DSDT only. Now, any table in the RSDT/XSDT can be replaced by the host OS. (including the DSDT).

2009-02-07ACPICA: Fix table entry truncation calculationMyron Stowe1-4/+3
During early boot, ACPI RSDT/XSDT table entries are gathered into the 'initial_tables[]' array. This array is currently statically defined (see ./drivers/acpi/tables.c). When there are more table entries than can be held in the 'initial_tables[]' array, the message "Truncating N table entries!" is output. As currently implemented, this message will always erroneously calculate N as 0. This patch fixes the calculation that determines how many table entries will be missing (truncated).
