When an ioremap() occurs, the underlying infrastructure works on a 'page' based granularity. As such, an ioremap() request for 1 byte for example, will end up mapping in an entire (PAGE_SIZE) page. Huang Ying took advantage of this in commit 15651291a2f8c11e7e6a42d8bfde7a213ff13262 by checking if subsequent ioremap() requests reside within any of the list's existing remappings still in place, and if so, incrementing a reference count on the existing mapping as opposed to performing another ioremap().

ACPI's 'system event' handing accesses specific fixed hardware registers; namely PM1a event, PM1b event, GPE0, and GPE1 register blocks which are declared within the FADT. If these registers are backed by MMIO, as opposed to I/O port space, accessing them within interrupt context will cause a panic as acpi_os_read_memory() depends on ioremap() in such cases - BZ 18012. By utilizing the functionality provided in the previous two patches - ACPI: Maintain a list of ACPI memory mapped I/O remappings, and, ACPI: Add interfaces for ioremapping/iounmapping ACPI registers - accesses to ACPI MMIO areas will now be safe from within interrupt contexts (IRQ and/or NMI) provided the area was pre-mapped.

The current ACPI I/O accessing methods - acpi_read() and acpi_write() - end up calling ioremap() when accessing MMIO. This prevents use of these methods within interrupt context (IRQ and/or NMI), since ioremap() may block to allocate memory. Maintaining a list of MMIO remappings enables accesses to such areas from within interrupt context provided they have been pre-mapped.

Wysocki <rjw@xxxxxxx> Date: Sat Oct 23 19:35:15 2010 +0200 ACPI / Battery: Return -ENODEV for unknown values in get_property() The function acpi_battery_get_property() is called by the power supply framework's function power_supply_show_property() implementing the sysfs interface for power supply devices as the ACPI battery driver's ->get_property() callback. Thus it is supposed to return error code if the value of the given property is unknown. Unfortunately, however, it returns 0 in those cases and puts a wrong (negative) value into the intval field of the union power_supply_propval object provided by power_supply_show_property(). In consequence, wrong negative values are read by user space from the battery's sysfs files. Fix this by making acpi_battery_get_property() return -ENODEV for properties with unknown values (-ENODEV is returned, because power_supply_uevent() returns with error for any other error code returned by power_supply_show_property()).

Wysocki <rjw@xxxxxxx> Date: Fri Oct 22 02:35:54 2010 +0200 ACPI / PM: Fix reference counting of power resources The reference counting of ACPI power resources is currently broken for a few reasons. First, instead of using a simple reference counter per power resource it uses a list of objects representing refereces to the given power resource from devices. This leads to the second breakage, because it prevents power resources from being referenced more than once by one device, which is necessary if the device is configured to signal wakeup. Namely, when putting the device into a low power state we first call acpi_enable_wakeup_device_power() that should reference count power resources needed for signaling wakeup and then we call acpi_power_transition() to power off the device. The latter call drops references to the device's power resources, possibly including the ones added by acpi_enable_wakeup_device_power(), so the device can't signal wakeup as a result. Apart from this, the locking in acpi_power_on() and acpi_power_off_device() doesn't prevent all possible races from happening, which may be problematic for runtime PM and asynchronous suspend and resume. Fix the problem by using a counter for power resources reference counting and putting the evaluation of ACPI _ON and _OFF methods under the power resource mutex.

Finding this on affected machines can be cumbersome, because ACPI_EC_DELAY is a compile option -> make it configurable via boot param. This can even be provided writable at runtime via: /sys/modules/acpi/parameters/ec_delay Known machines where this helps: Some HP machines where for whatever reasons specific EC accesses take very long at resume from S3 (in _WAK function). The AE_TIME error is passed upwards and the ACPI interpreter will not execute the rest of the _WAK function which results in not properly initialized devices/variables with different side-effects. Afaik, on some MSI machines this helped as well. If this param is needed there probably are underlying problems like: - EC firmware bug - A kernel EC driver bug - An ACPI interpreter behavior (e.g. timings when specific EC accesses happen and how) which the EC does not like - ... which should get evaluated further, but often are nasty or impossible to fix from OS side.

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.

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.
