2008-12-31ACPICA: FADT: set acpi_gbl_use_default_register_widths to TRUE by default[email protected]1-68/+105
This returns the FADT support to the original behavior, which is to use default register widths. However, now check each register definition and report a warning if it differs from the default. This is a first step to moving away from the default widths, rather than outright believing the widths in all FADTs for all machines, considered rather dangerous until more data is obtained.

2008-12-31ACPICA: FADT parsing changes and fixesBob Moore1-20/+105
1) Update the register lengths for the PM1 event blocks. The length must be divided by two in order to use these to access the status registers. 2) Add run-time option to use default register lengths to override a faulty FADT. 3) Add warning message if any of the X64 address structures contain a length that does not match the legacy length earlier in the FADT. 4) Move all FADT warning messages into the ValidateFadt function.

2008-12-31ACPICA: Restructure includes into public/privateBob Moore6-0/+6
acpi.h now includes only the "public" acpica headers. All other acpica headers are "private" and should not be included by acpica users. One new file, accommon.h is used to include the commonly used private headers for acpica code generation. Future plans are to move all private headers to a new subdirectory.

2008-10-22ACPICA: Allow same ACPI table to be loaded/unloaded more than onceBob Moore1-7/+42
Without this change, a table cannot be loaded again once it has been loaded/unloaded one time. The current mechanism does not unregister a table upon an unload.

2008-10-10ACPI: fix FADT parsingJan Beulich1-7/+25
The (1.0 inherited) separate length fields in the FADT are byte granular. Further, PM1a/b may have distinct lengths (if using the v2 fields was okay) and may live in distinct address spaces. acpi_tb_convert_fadt() should account for all of these conditions. Apart from these changes I'm puzzled by the fact that, not just for acpi_gbl_xpm1{a,b}_enable, acpi_hw_low_level_{read,write}() get an explicit size passed rather than using the size found in the passed GAS. What happens on a platform that defines PM1{a,b} wider than 16 bits? Of course, acpi_hw_low_level_{read,write}() at present are entirely un-prepared to deal with sizes other than 8, 16, or 32, not to speak of a non-zero bit_offset or access_width...

2008-06-11ACPICA: Ignore ACPI table signature for Load() operatorBob Moore1-18/+7
Only "SSDT" is acceptable to the ACPI spec, but tables are seen with OEMx and null sigs. Therefore, signature validation is worthless.

2007-12-14ACPI: tables: complete searching upon RSDP w/ bad checksum.Len Brown2-4/+2
ACPI tables follow a tree structure in memory. The root of the tree is the RSDP (Root System Description Pointer). To find the RSDP, the OS searches for the signature "RSD PTR " in well known physical memory locations. Then the OS computes a table checksum to verify that the signature is really part of a valid table header. Some systems have a proper signature but an invalid checksum; followed elsewhere by a proper signature with valid checksum. http://bugzilla.kernel.org/show_bug.cgi?id=9444 The Linux RSDP scanning code bailed out on those systems and as a result they booted with ACPI disabled. Fix this by deleting the Linux RSDP scanning code and plugging in the ACPICA RSDP scanning code. Signed-off-by: Len Brown <[email protected]>

2007-08-24ACPI: Validate XSDT, use RSDT if XSDT failsZhao Yakui1-0/+71
ACPI 1.0 used an RSDT with 32-bit physical addresses. ACPI 2.0 adds an XSDT with 32-bit physical addresses. An ACPI 2.0 aware OS is supposed to use the XSDT (when present) instead of the RSDT. However, several systems have failed because the XSDT contains NULL entries -- while it is missing pointers to needed tables, such as SSDTs. When we find an XSDT with NULL entries, discard it and use the ACPI 1.0 RSDT instead. http://bugzilla.kernel.org/show_bug.cgi?id=8630 Signed-off-by: Zhao Yakui <[email protected]> Signed-off-by: Len Brown <[email protected]>
2007-07-26ACPI: add "acpi_no_auto_ssdt" bootparamLen Brown1-0/+23
"acpi_no_auto_ssdt" prevents Linux from automatically loading all the SSDTs listed in the RSDT/XSDT. This is needed for debugging. In particular, it allows a DSDT override to optionally be a DSDT+SSDT override. http://bugzilla.kernel.org/show_bug.cgi?id=3774 Signed-off-by: Len Brown <[email protected]>
2007-07-03ACPICA: Clear reserved fields for incoming ACPI 1.0 FADTsBob Moore1-18/+26
Fixed a problem with the internal FADT conversion where ACPI 1.0 FADTs that contained invalid non-zero values in reserved fields could cause later failures because these fields have meaning in later revisions of the FADT. For incoming ACPI 1.0 FADTs, these fields are now always zeroed. (Preferred_PM_Profile, PSTATE_CNT, CST_CNT, IAPC_BOOT_FLAGS.)

2007-04-28ACPICA: clear fields reserved before FADT r3Bob Moore1-0/+12
Linux-2.6.21 stopped booting on a P4/HT because Linux wrote the FADT.CST_CNT value to the SMI_CMD. Apparently this stumbled over some SMM instability, such as confusing SMM when invoking it from cpu1. Linux did this because even though the r2 FADT reserves the CST_CNT field, this BIOS set that field and Linux used it. Turns out that up through 2.6.20 we explicitly cleared cst_control for r2 FADTs. So here we go back to doing that, plus also clear some additional fields that are reserved until FADT r3. http://bugzilla.kernel.org/show_bug.cgi?id=8346 Signed-off-by: Bob Moore <[email protected]> Signed-off-by: Len Brown <[email protected]>
