2009-03-26ACPICA: Add function to handle PM1 control registersBob Moore
Added acpi_hw_write_pm1_control. This function writes both of the PM1 control registers (A/B). These registers are different than than the PM1 A/B status and enable registers in that different values can be written to the A/B registers. Most notably, the SLP_TYP bits can be different, as per the values returned from the _Sx predefined methods.

2009-03-26ACPICA: Remove redundant ACPI_BITREG_SLEEP_TYPE_BBob Moore
This type is the same as TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to simply SLEEP_TYPE.

2009-03-26ACPICA: Fix parameter validation for acpi_read/writeBob Moore
Now return AE_BAD_PARAMETER if the input register pointer is null, and AE_BAD_ADDRESS if the register has an address of zero. Previously, these cases simply returned AE_OK. For optional registers such as PM1B status/enable/control, the caller should check for a valid register address before calling.

2009-03-26ACPICA: For PM1B registers, do not shift value read or writtenBob Moore
The PM1B registers are mirrors of the PM1A registers with different bits actually implemented. From the ACPI specification: "Although the bits can be split between the two register blocks (each register block has a unique pointer within the FADT), the bit positions are maintained. The register block with unimplemented bits (that is, those implemented in the other register block) always returns zeros, and writes have no side effects" 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>
2009-03-26ACPICA: Remove extra write for acpi_hw_clear_acpi_statusBob Moore
This function was writing an optional PM1B status register twice. The existing call to the low-level acpi_hw_register_write automatically handles a possibly split PM1 A/B register.

2009-03-26ACPICA: Fix writes to optional PM1B registersBob Moore
On read, shift B register bits above the A bits. On write, shift B bits down to zero before writing the B register. New: acpi_hw_read_multiple, acpi_hw_write_multiple. These two functions now transparently handle the (possible) split registers for PM1 Status, Enable, and Control.

2009-03-26ACPICA: Split out PM1 status registers from the FADTBob Moore
Add new globals for the PM1 status registers (A/B), similar to the way the PM1 enable registers are handled. Instead of overloading the FADT Event Register blocks. This makes the code clearer and less prone to error. 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>

2009-03-26ACPICA: Allow OS override of all ACPI tablesBob Moore

2009-02-07ACPICA: Fix table entry truncation calculationMyron Stowe
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). This modification may be used under either the GPL or the BSD-style license used for Intel ACPI CA code.
