2011-05-29ACPI: Add D3 cold stateLin Ming1-2/+3
_SxW returns an Integer containing the lowest D-state supported in state Sx. If OSPM has not indicated that it supports _PR3, then the value “3” corresponds to D3. If it has indicated _PR3 support, the value “3” represents D3hot and the value “4” represents D3cold. Linux does set _OSC._PR3, so we should fix it to expect that _SxW can return 4.

2011-05-29ACPI: processor: fix processor_physically_present in UP kernelLin Ming1-7/+0
Usually, there are multiple processors defined in ACPI table, for example Scope (_PR) { Processor (CPU0, 0x00, 0x00000410, 0x06) {} Processor (CPU1, 0x01, 0x00000410, 0x06) {} Processor (CPU2, 0x02, 0x00000410, 0x06) {} Processor (CPU3, 0x03, 0x00000410, 0x06) {} } processor_physically_present(...) will be called to check whether those processors are physically present. Currently we have below codes in processor_physically_present, cpuid = acpi_get_cpuid(...); if ((cpuid == -1) && (num_possible_cpus() > 1)) return false; return true; In UP kernel, acpi_get_cpuid(...) always return -1 and num_possible_cpus() always return 1, so processor_physically_present(...) always returns true for all passed in processor handles. This is wrong for UP processor or SMP processor running UP kernel. This patch removes the !SMP version of acpi_get_cpuid(), so both UP and SMP kernel use the same acpi_get_cpuid function. And for UP kernel, only processor 0 is valid. https://bugzilla.kernel.org/show_bug.cgi?id=16548 https://bugzilla.kernel.org/show_bug.cgi?id=16357 Tested-by: Anton Kochkov <anton.kochkov@gmail.com> Tested-by: Ambroz Bizjak <ambrop7@gmail.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2011-03-21ACPI, APEI, Add ERST record ID cacheHuang Ying1-2/+3
APEI ERST firmware interface and implementation has no multiple users in mind. For example, if there is four records in storage with ID: 1, 2, 3 and 4, if two ERST readers enumerate the records via GET_NEXT_RECORD_ID as follow, reader 1 reader 2 1 2 3 4 -1 -1 where -1 signals there is no more record ID. Reader 1 has no chance to check record 2 and 4, while reader 2 has no chance to check record 1 and 3. And any other GET_NEXT_RECORD_ID will return -1, that is, other readers will has no chance to check any record even they are not cleared by anyone. This makes raw GET_NEXT_RECORD_ID not suitable for used by multiple users. To solve the issue, an in-memory ERST record ID cache is designed and implemented. When enumerating record ID, the ID returned by GET_NEXT_RECORD_ID is added into cache in addition to be returned to caller. So other readers can check the cache to get all record ID available.

2011-02-24ACPI: Remove the wakeup.run_wake_count device fieldRafael J. Wysocki1-1/+0
The wakeup.run_wake_count ACPI device field is only used by the PCI runtime PM code to "protect" devices from being prepared for generating wakeup signals more than once in a row. However, it really doesn't provide any protection, because (1) all of the functions it is supposed to protect use their own reference counters effectively ensuring that the device will be set up for generating wakeup signals just once and (2) the PCI runtime PM code uses wakeup.run_wake_count in a racy way, since nothing prevents acpi_dev_run_wake() from being called concurrently from two different threads for the same device. Remove the wakeup.run_wake_count ACPI device field which is unnecessary, confusing and used in a wrong way. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

2011-01-12ACPI: Drop device flag wake_capableRafael J. Wysocki1-2/+1
The wake_capable ACPI device flag is not necessary, because it is only used in scan.c for recording the information that _PRW is present for the given device. That information is only used by acpi_add_single_object() to decide whether or not to call acpi_bus_get_wakeup_device_flags(), so the flag may be dropped if the _PRW check is moved to acpi_bus_get_wakeup_device_flags(). Moreover, acpi_bus_get_wakeup_device_flags() always returns 0, so it really should be void. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>

For this purpose introduce __acpi_bus_set_power() setting the power state of an ACPI device without updating its device->power.state field and make acpi_bus_set_power() and acpi_bus_update_power() use it (acpi_bus_set_power() retains the current behavior for now).
