2010-07-24ACPI / Sleep: Allow the NVS saving to be skipped during suspend to RAMRafael J. Wysocki
Commit 2a6b69765ad794389f2fc3e14a0afa1a995221c2 (ACPI: Store NVS state even when entering suspend to RAM) caused the ACPI suspend code save the NVS area during suspend and restore it during resume unconditionally, although it is known that some systems need to use acpi_sleep=s4_nonvs for hibernation to work. To allow the affected systems to avoid saving and restoring the NVS area during suspend to RAM and resume, introduce kernel command line option acpi_sleep=nonvs and make acpi_sleep=s4_nonvs work as its alias temporarily (add acpi_sleep=s4_nonvs to the feature removal file).

2010-07-22ACPI: create "processor.bm_check_disable" boot paramLen Brown
processor.bm_check_disable=1" prevents Linux from checking BM_STS before entering C3-type cpu power states. This may be useful for a system running acpi_idle where the BIOS exports FADT C-states, _CST IO C-states, or _CST FFH C-states with the BM_STS bit set; while configuring the chipset to set BM_STS more frequently than perhaps is optimal. Note that such systems may have been developed using a tickful OS that would quickly clear BM_STS, rather than a tickless OS that may go for some time between checking and clearing BM_STS. Note also that an alternative for newer systems is to use the intel_idle driver, which always ignores BM_STS, relying Linux device drivers to register constraints explicitly via PM_QOS. https://bugzilla.kernel.org/show_bug.cgi?id=15886 Signed-off-by: Len Brown <len.brown@intel.com>
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: processor: fix processor_physically_present on UPAlex Chiang
The commit 5d554a7bb06 (ACPI: processor: add internal processor_physically_present()) is broken on uniprocessor (UP) configurations, as acpi_get_cpuid() will always return -1. We use the value of num_possible_cpus() to tell us whether we got an invalid cpuid from acpi_get_cpuid() in the SMP case, or if instead, we are UP, in which case num_possible_cpus() is #defined as 1. We use num_possible_cpus() instead of num_online_cpus() to protect ourselves against the scenario of CPU hotplug, and we've taken down all the CPUs except one.

2010-06-28ACPI: handle systems which asynchoronously enable ACPI modeLen Brown
Folklore suggested that such systems existed in the pre-history of ACPI. However, we removed the SCI_EN polling loop from acpi_hw_set_mode() in b430acbd7c4b919886fa7fd92eeb7a695f1940d3 because it delayed resume by 3 seconds on boxes that refused to set SCI_EN. Matthew removed the call to acpi_enable() from the suspend resume path. James found a modern system that still needs to be polled upon boot. So here we restore the workaround, except that we put it in acpi_enable() rather than the low level acpi_hw_set_mode(). https://bugzilla.kernel.org/show_bug.cgi?id=16271 Signed-off-by: Len Brown <len.brown@intel.com>

2010-06-17ACPI / PM: Do not enable GPEs for system wakeup in advanceRafael J. Wysocki
After commit 9630bdd9b15d2f489c646d8bc04b60e53eb5ec78 (ACPI: Use GPE reference counting to support shared GPEs) the wakeup enable mask bits of GPEs are set as soon as the GPEs are enabled to wake up the system. Unfortunately, this leads to a regression reported by Michal Hocko, where a system is woken up from ACPI S5 by a device that is not supposed to do that, because the wakeup enable mask bit of this device's GPE is always set when acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(), although it should only be set if the device is supposed to wake up the system from the target state. To work around this issue, rework the ACPI power management code so that GPEs are not enabled to wake up the system upfront, but only during a system state transition when the target state of the system is known. [Of course, this means that the reference counting of "wakeup" GPEs doesn't really make sense and it is sufficient to set/unset the wakeup mask bits for them during system sleep transitions. This will allow us to simplify the GPE handling code quite a bit, but that change is too intrusive for 2.6.35.] Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15951 Signed-off-by: Rafael J.

2010-06-12ACPI / ACPICA: Fix sysfs GPE interfaceRafael J. Wysocki
The sysfs interface allowing user space to disable/enable GPEs doesn't work correctly, because a GPE disabled this way will be re-enabled shortly by acpi_ev_asynch_enable_gpe() if it was previosuly enabled by acpi_enable_gpe() (in which case the corresponding bit in its enable register's enable_for_run mask is set). To address this issue make the sysfs GPE interface use acpi_enable_gpe() and acpi_disable_gpe() instead of acpi_set_gpe() so that GPE reference counters are modified by it along with the values of GPE enable registers.

2010-06-12ACPI / ACPICA: Fix GPE initializationRafael J. Wysocki

As a result, some GPEs are enabled twice during the initialization.

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.

2010-06-11ACPI / ACPICA: Do not attempt to disable GPE when installing handlerRafael J. Wysocki
Commit 0f849d2cc6863c7874889ea60a871fb71399dd3f (ACPICA: Minimize the differences between linux GPE code and ACPICA code base) introduced a change attempting to disable a GPE before installing a handler for it in acpi_install_gpe_handler() which was incorrect. First, the GPE disabled by it is never enabled again (except during resume) which leads to battery insert/remove events not being reported on the Maxim Levitsky's machine. Second, the disabled GPE is still reported as enabled by the sysfs interface that only checks its enable register's enable_for_run mask.

https://bugzilla.kernel.org/show_bug.cgi?id=13931 describes a bug where a system fails to successfully resume after the second suspend. Maxim Levitsky discovered that this could be rectified by forcibly saving and restoring the ACPI non-volatile state. The spec indicates that this is only required for S4, but testing the behaviour of Windows by adding an ACPI NVS region to qemu's e820 map and registering a custom memory read/write handler reveals that it's saved and restored even over suspend to RAM.

Patch is against latest Linus master branch and is expected to be safe bug fix. You get: ACPI: HARDWARE addr space,NOT supported yet for each ACPI defined CPU which status is active, but exceeds maxcpus= count. As these "not booted" CPUs do not run an idle routine and echo X >/proc/acpi/processor/*/throttling did not work I couldn't find a way to really access not onlined/booted machines. Still this should get fixed and /proc/acpi/processor/X dirs of cores exceeding maxcpus should not show up. I wonder whether this could get cleaned up by truncating possible cpu mask and nr_cpu_ids to setup_max_cpus early some day (and not exporting setup_max_cpus anymore then).

There still is a race that may result in suspending the system in the middle of an EC transaction in progress, which leads to problems (like the kernel thinking that the ACPI global lock is held during resume while in fact it's not). To remove the race condition, modify the ACPI platform suspend and hibernate callbacks so that EC transactions are blocked right after executing the _PTS global control method and are allowed to happen again right after the low-level wakeup. Introduce acpi_pm_freeze() that will disable GPEs, wait until the event queues are empty and block EC transactions. Use it wherever GPEs are disabled in preparation for switching local interrupts off. Introduce acpi_pm_thaw() that will allow EC transactions to happen again and enable runtime GPEs. Use it to balance acpi_pm_freeze() wherever necessary. In addition to that use acpi_ec_resume_transactions_early() to unblock EC transactions as early as reasonably possible during resume. Also unblock EC transactions in acpi_hibernation_finish() and in the analogous suspend routine to make sure that the EC transactions are enabled in all error paths.
