* ACPICA: Make acpi_thread_id no longer configurable, always u64Lin Ming2010-10-011-1/+1
| | | | | | | | | | | | | Change definition of acpi_thread_id to always be a u64. This simplifies the code, especially any printf output. u64 is the only common data type for all thread_id types across all operating systems. We now force the OSL to cast the native thread_id type to u64 before returning the value to ACPICA (via acpi_os_get_thread_id).

* ACPICA: Obsolete the acpi_os_derive_pci_id OSL interfaceBob Moore2010-10-011-0/+7
| | | | | | | | | | | | | This function is not OS-dependent and has been replaced by acpi_hw_derive_pci_id, which is now in the ACPICA core code. Local implementations of acpi_os_derive_pci_id are no longer necessary and are removed.

* ACPICA: Remove obsolete GPE functionBob Moore2010-07-061-3/+0
| | | | | | | | | Remove acpi_hw_write_gpe_enable_reg, it had been reduced down to a single line of code, and called from only one place. 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>
* ACPICA: Rename acpi_hw_gpe_register_bitLin Ming2010-07-061-1/+1
| | | | | | | | Rename acpi_hw_gpe_register_bit to acpi_hw_get_gpe_register_bit in order to be same with ACPICA code base. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI / ACPICA: Fix low-level GPE manipulation codeRafael J. Wysocki2010-06-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | ACPICA uses acpi_ev_enable_gpe() for enabling GPEs at the low level, which is incorrect, because this function only enables the GPE if the corresponding bit in its enable register's enable_for_run mask is set. This causes acpi_set_gpe() to work incorrectly if used for enabling GPEs that were not previously enabled with acpi_enable_gpe(). As a result, among other things, wakeup-only GPEs are never enabled by acpi_enable_wakeup_device(), so the devices that use them are unable to wake up the system. To fix this issue remove acpi_ev_enable_gpe() and its counterpart acpi_ev_disable_gpe() and replace acpi_hw_low_disable_gpe() with acpi_hw_low_set_gpe() that will be used instead to manipulate GPE enable bits at the low level. Make the users of acpi_ev_enable_gpe() and acpi_ev_disable_gpe() call acpi_hw_low_set_gpe() instead and make sure that GPE enable masks are only updated by acpi_enable_gpe() and acpi_disable_gpe() when GPE reference counters change from 0 to 1 and from 1 to 0, respectively.

* ACPI / ACPICA: Use helper function for computing GPE masksRafael J. Wysocki2010-06-111-0/+3
| | | | | | | | | | | In quite a few places ACPICA needs to compute a GPE enable mask with only one bit, corresponding to a given GPE, set. Currently, that computation is always open coded which leads to unnecessary code duplication. Fix this by introducing a helper function for computing one-bit GPE enable masks and using it where appropriate. Signed-off-by: Rafael J.

* ACPICA: Update all ACPICA copyrights and signons to 2010Bob Moore2010-01-221-1/+1
| | | | | | | | | | Add 2010 copyright to all module headers and signons, including the Linux header. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and all utilities.

* ACPICA: Add 64-bit support to acpi_read and acpi_writeBob Moore2009-08-271-0/+8
| | | | | | | | | | | Needed by drivers for new ACPi tables. Internal versions of these functions still use 32-bit max transfers, in order to minimize disruption and stack use for the standard ACPI registers (FADT-based).

* ACPICA: Add function to handle PM1 control registersBob Moore2009-03-261-2/+3
| | | | | | | | | | | | | 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.
