2010-10-15ACPI / PM: Fix problems with acpi_pm_device_sleep_state()Rafael J. Wysocki
There is a number of problems with acpi_pm_device_sleep_state() now. First, if _S0W is not defined, it prevents devices from being put into D3 by PCI runtime PM, which shouldn't happen. Second, it shouldn't use adev->wakeup.state.enabled, because if it's set, it only means that either the device is permanently enabled to wake up the system, or that it has been enabled to do that through /proc/acpi/wakeup. Finally, it should be compiled if CONFIG_PM_SLEEP is not set, so that PCI runtime PM works correctly in that case. Fix these problems.

2010-09-24ACPI / ACPICA: Defer enabling of runtime GPEs (v3)Rafael J. Wysocki
The current ACPI GPEs initialization code has a problem that it enables some GPEs pointed to by device _PRW methods, generally intended for signaling wakeup events (system or device wakeup). These GPEs are then almost immediately disabled by the ACPI namespace scanning code with the help of acpi_gpe_can_wake(), but it would be better not to enable them at all until really necessary. Modify the initialization of GPEs so that the ones that have associated _Lxx or _Exx methods and are not pointed to by any _PRW methods will be enabled after the namespace scan is complete.

2010-08-24ACPI/PCI: Do not preserve _OSC control bits returned by a query Rafael J. Wysocki
There is the assumption in acpi_pci_osc_control_set() that it is always sufficient to compare the mask of _OSC control bits to be requested with the result of an _OSC query where all of the known control bits have been checked. However, in general, that need not be the case. For example, if an _OSC feature A depends on an _OSC feature B and control of A, B plus another _OSC feature C is requested simultaneously, the BIOS may return A, B, C, while it would only return C if A and C were requested without B. That may result in passing a wrong mask of _OSC control bits to an _OSC control request, in which case the BIOS may only grant control of a subset of the requested features. Moreover, acpi_pci_run_osc() will return error code if that happens and the caller of acpi_pci_osc_control_set() will not know that it's been granted control of some _OSC features. Consequently, the system will generally not work as expected. Apart from this acpi_pci_osc_control_set() always uses the mask of _OSC control bits returned by the very first invocation of acpi_pci_query_osc(), but that is done with the second argument equal to OSC_PCI_SEGMENT_GROUPS_SUPPORT which generally happens to affect the returned _OSC control bits. For these reasons, make acpi_pci_osc_control_set() always check if control of the requested _OSC features will be granted before making the final control request. As a result, the osc_control_qry and osc_queried members of struct acpi_pci_root are not necessary any more, so drop them and remove the remaining code referring to them. Signed-off-by: Rafael J.

2010-08-12acpi: fix bogus preemption logicThomas Gleixner
The ACPI_PREEMPTION_POINT() logic was introduced in commit 8bd108d (ACPICA: add preemption point after each opcode parse). The follow up commits abe1dfab6, 138d15692, c084ca70 tried to fix the preemption logic back and forth, but nobody noticed that the usage of in_atomic_preempt_off() in that context is wrong. The check which guards the call of cond_resched() is: if (!in_atomic_preempt_off() && !irqs_disabled()) in_atomic_preempt_off() is not intended for general use as the comment above the macro definition clearly says: * Check whether we were atomic before we did preempt_disable(): * (used by the scheduler, *after* releasing the kernel lock) On a CONFIG_PREEMPT=n kernel the usage of in_atomic_preempt_off() works by accident, but with CONFIG_PREEMPT=y it's just broken. The whole purpose of the ACPI_PREEMPTION_POINT() is to reduce the latency on a CONFIG_PREEMPT=n kernel, so make ACPI_PREEMPTION_POINT() depend on CONFIG_PREEMPT=n and remove the in_atomic_preempt_off() check.

2010-07-22ACPI: skip checking BM_STS if the BIOS doesn't ask for itLen Brown
It turns out that there is a bit in the _CST for Intel FFH C3 that tells the OS if we should be checking BM_STS or not. Linux has been unconditionally checking BM_STS. If the chip-set is configured to enable BM_STS, it can retard or completely prevent entry into deep C-states -- as illustrated by turbostat: http://userweb.kernel.org/~lenb/acpi/utils/pmtools/turbostat/ ref: Intel Processor Vendor-Specific ACPI Interface Specification table 4 "_CST FFH GAS Field Encoding" Bit 1: Set to 1 if OSPM should use Bus Master avoidance for this C-state https://bugzilla.kernel.org/show_bug.cgi?id=15886 Signed-off-by: Len Brown <len.brown@intel.com>
2010-07-12ACPI / ACPICA: Do not execute _PRW methods during initializationRafael J. Wysocki
Currently, during initialization ACPICA walks the entire ACPI namespace in search of any device objects with assciated _PRW methods. All of the _PRW methods found are executed in the process to extract the GPE information returned by them, so that the GPEs in question can be marked as "able to wakeup" (more precisely, the ACPI_GPE_CAN_WAKE flag is set for them). The only purpose of this exercise is to avoid enabling the CAN_WAKE GPEs automatically, even if there are _Lxx/_Exx methods associated with them. However, it is both costly and unnecessary, because the host OS has to execute the _PRW methods anyway to check which devices can wake up the system from sleep states. Moreover, it then uses full information returned by _PRW, including the GPE information, so it can take care of disabling the GPEs if necessary. Remove the code that walks the namespace and executes _PRW from ACPICA and modify comments to reflect that change. Make acpi_bus_set_run_wake_flags() disable GPEs for wakeup devices so that they don't cause spurious wakeup events to be signaled. This not only reduces the complexity of the ACPICA initialization code, but in some cases it should reduce the kernel boot time as well. Unfortunately, for this purpose we need a new ACPICA function, acpi_gpe_can_wake(), to be called by the host OS in order to disable the GPEs that can wake up the system and were previously enabled by acpi_ev_initialize_gpe_block() or acpi_ev_update_gpes() (such a GPE should be disabled only once, because the initialization code enables it only once, but it may be pointed to by _PRW for multiple devices and that's why the additional function is necessary).

2010-07-06ACPICA: Drop acpi_set_gpeRafael J. Wysocki
The acpi_set_gpe() function is a little awkward, because it doesn't really work as advertised in the "disable" case. Namely, if a GPE has been enabled with acpi_enable_gpe() and triggered a notification to occur, and if acpi_set_gpe() is used to disable it before acpi_ev_asynch_enable_gpe() runs, the GPE will be immediately enabled by the latter as though the acpi_set_gpe() had no effect. Thus, since it's been possible to make all of its callers use alternative operations to disable or enable GPEs, acpi_set_gpe() can be dropped. Signed-off-by: Rafael J.

2010-07-06ACPICA: Introduce acpi_gpe_wakeup()Rafael J. Wysocki
ACPICA uses reference counters to avoid disabling GPEs too early in case they have been enabled for many times. This is done separately for runtime and for wakeup, but the wakeup GPE reference counter is not really necessary, because GPEs are only enabled to wake up the system at the hardware level by acpi_enter_sleep_state(). Thus it only is necessary to set the corresponding bits in the wakeup enable masks of these GPEs' registers right before the system enters a sleep state. Moreover, the GPE wakeup enable bits can only be set when the target sleep state of the system is known and they need to be cleared immediately after wakeup regardless of how many wakeup devices are associated with a given GPE. On the basis of the above observations, introduce function acpi_gpe_wakeup() to be used for setting or clearing the enable bit corresponding to a given GPE in its enable register's enable_for_wake mask. Modify the ACPI suspend and wakeup code the use acpi_gpe_wakeup() instead of acpi_{enable|disable}_gpe() to set and clear GPE enable bits in their registers' enable_for_wake masks during system transitions to a sleep state and back to the working state, respectively. [This will allow us to drop the third argument of acpi_{enable|disable}_gpe() and simplify the GPE handling code.] Signed-off-by: Rafael J.

2010-06-12ACPI / ACPICA: Avoid writing full enable masks to GPE registersRafael J. Wysocki
ACPICA uses acpi_hw_write_gpe_enable_reg() to re-enable a GPE after an event signaled by it has been handled. However, this function writes the entire GPE enable mask to the GPE's enable register which may not be correct. Namely, if one of the other GPEs in the same register was previously enabled by acpi_enable_gpe() and subsequently disabled using acpi_set_gpe(), acpi_hw_write_gpe_enable_reg() will re-enable it along with the target GPE. To fix this issue rework acpi_hw_write_gpe_enable_reg() so that it calls acpi_hw_low_set_gpe() with a special action value, ACPI_GPE_COND_ENABLE, that will make it only enable the GPE if the corresponding bit in its register's enable_for_run mask is set.

2010-06-12ACPI / ACPICA: Fix low-level GPE manipulation codeRafael J. Wysocki
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.
