2012-07-17ACPICA: AcpiSrc: Fix some translation issues for Linux conversionBob Moore1-5/+5
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.)

2012-06-01ACPICA: Add FADT error message for GAS BitWidth overflowBob Moore1-7/+25
Error for possible overflow during conversion from 32-bit legacy register addresses to GAS format. The GAS struct contains a one-byte BitWidth field, meaning that the maximum length of a register is 255 bits.

2012-03-21ACPICA: Fix regression in FADT revision checksJulian Anastasov1-4/+4
commit 64b3db22c04586997ab4be46dd5a5b99f8a2d390 (2.6.39), "Remove use of unreliable FADT revision field" causes regression for old P4 systems because now cst_control and other fields are not reset to 0. The effect is that acpi_processor_power_init will notice cst_control != 0 and a write to CST_CNT register is performed that should not happen. As result, the system oopses after the "No _CST, giving up" message, sometimes in acpi_ns_internalize_name, sometimes in acpi_ns_get_type, usually at random places. May be during migration to CPU 1 in acpi_processor_get_throttling. Every one of these settings help to avoid this problem: - acpi=off - processor.nocst=1 - maxcpus=1 The fix is to update acpi_gbl_FADT.header.length after the original value is used to check for old revisions. https://bugzilla.kernel.org/show_bug.cgi?id=42700 https://bugzilla.redhat.com/show_bug.cgi?id=727865 Signed-off-by: Julian Anastasov <ja@ssi.bg> Acked-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-03-27ACPICA: FADT: Favor 32-bit FACS and DSDT addressesBob Moore1-2/+6
If both the 32-bit and 64-bit addresses are non-null, use the 32-bit address. Provides Windows compatibility. 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>
2009-03-27ACPICA: FADT: Favor 32-bit register addresses for compatibilityBob Moore1-35/+51
Use the 32-bit register addresses whenever they are non-zero. This means that the 32-bit addresses are favored over the 64-bit (GAS) addresses. The 64-bit addresses are only used if the 32-bit addresses are zero. This change provides compatibility with all versions of Windows. The worst case that this solves is when both the 32-bit and 64-bit addresses are non-zero, but only the 32-bit addresses are actually valid. This appears to happen in some BIOSes because in this case, Windows uses the 32-bit addresses.
