* ACPI: use macro to replace hard numberYinghai Lu2008-11-061-1/+1
| | | | | | | | | | Impact: cleanup Use MACRO for rev 3 fadt id instead of 3 directly. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: fix FADT parsingJan Beulich2008-10-101-7/+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...

* Revert "Fix FADT parsing"Andi Kleen2008-07-181-11/+6
| | | | | | | | | | This reverts commit 01a5bba576b9364b33f61f0cd9fa70c2cf5535e2. There seem to be some FADTs around with bogus information in the v2 fields. Revert this patch for now until this can be properly resolved. Signed-off-by: Andi Kleen <ak@linux.intel.com>

* ACPICA: Clear reserved fields for incoming ACPI 1.0 FADTsBob Moore2007-07-031-18/+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.)

* ACPICA: clear fields reserved before FADT r3Bob Moore2007-04-281-0/+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 <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
