* ACPICA: FADT: Remove extraneous warning for very large GPE registersLinn Crosetto2013-04-121-0/+4
| | | | | | | | | | | | | This change removes a size mismatch warning if the legacy length field for a GPE register set is larger than the 64-bit GAS structure can accomodate. GPE register sets can be larger than the 255 bit limitation of the GAS structure. Linn Crosetto (linn@hp.com).

* ACPICA: Cleanup updated comments.Lv Zheng2013-01-101-2/+3
| | | | | | | | | | | | | | | | | | | 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 558 lines of 20121018 divergence.diff. This patch reduces the source code diff between Linux and ACPICA by cleaning the comments that already have been updated in ACPICA. There is no extra indentation done in this patch. Even the empty line deletions and insertions are also splitted into another cleanup patch so that this patch can be easily reviewed, and the binary differences can be held to a lowest level.

* ACPICA: Add FADT error message for GAS BitWidth overflowBob Moore2012-06-011-7/+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.

* ACPICA: Fix regression in FADT revision checksJulian Anastasov2012-03-211-4/+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>

* ACPICA: FADT: Favor 32-bit register addresses for compatibilityBob Moore2009-03-271-35/+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.
