| | | | | | | * | | | Thermal: Make Thermal trip points writeableDurgadoss R2012-07-24

This patch makes the trip point temperatures writeable on a per-trip point basis, and modifies the required function call in thermal.c. This patch also updates the Documentation to reflect the new change.

As a result, the driver's add() ops may return success even though the device failed to initialize. For example, some BIOS may describe two ACADs in the same DSDT. The second ACAD device will fail to register, but ACPI driver's add() ops returns sucessfully. The ACPI device will receive ACPI notification and cause OOPS. https://bugzilla.redhat.com/show_bug.cgi?id=772730 Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Len Brown <len.brown@intel.com>

The regression got spread through stable kernels. On 3.0.X it got introduced via 3.0.18. Such platforms may be rare, but do exist. Look out for a disabled processor with acpi_id 0 in dmesg: ACPI: LAPIC (acpi_id[0x00] lapic_id[0x10] disabled) This problem has been observed on a: HP Proliant BL280c G6 blade This patch restricts the introduced workaround to platforms with nr_cpu_ids <= 1.

This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981 Cc: stable@vger.kernel.org Signed-off-by: Stuart Hayes <Stuart_Hayes@Dell.com> Signed-off-by: Len Brown <len.brown@intel.com>

This patch fixes the regression that caused this issue in the first place. acpi_idle_suspend flag is essential on some x86 systems to prevent the cpus from going to deeper C-states when suspend is triggered ( commit b04e7bdb984 ) So reverting the commit 3439a8da is essential. By default, irqs are disabled in cpu_idle arch specific call and re-enabled in idle state return path . During suspend, the acpi_idle_suspend flag is set, which prevents the cpus from going to deeper idle states, it is essential to enabling the irqs in this return path too. To address the suspend issue, we were not re-enabling the interrupts while returning from acpi_idle_enter_bm() routine if acpi_idle_suspend flag is set. and this caused suspend failure. In addition to the above, to improve the readability of the code, return of -ENIVAL is replaced with -EBUSY in acpi_idle_suspend return path. Implying that the system is currently busy when suspend is in progress, which prevents the cpus from entering deeper C-states.

All ACPI hotplug handlers must call this function when evaluating _OST for hotplug operations. If the platform does not support _OST, this function returns AE_NOT_FOUND and has no effect on the platform. ACPI_HOTPLUG_OST is defined when all relevant ACPI hotplug operations, such as CPU, memory and container hotplug, are enabled. This assures consistent behavior among the hotplug operations with regarding the _OST support. When ACPI_HOTPLUG_OST is not defined, this function is a no-op. ACPI PCI hotplug is not enhanced to support _OST at this time since it is a legacy method being replaced by PCIe native hotplug. _OST support for ACPI PCI hotplug may be added in future if necessary. Some platforms may require the OS to support _OST in order to support ACPI hotplug operations. For example, if a platform has the management console where user can request a hotplug operation from, this _OST support would be required for the management console to show the result of the hotplug request to user. Added macro definitions of _OST source events and status codes. Also renamed OSC_SB_CPUHP_OST_SUPPORT to OSC_SB_HOTPLUG_OST_SUPPORT since this _OSC bit is not specific to CPU hotplug. This bit is defined in Table 6-147 of ACPI 5.0 as follows. Bits: 3 Field Name: Insertion / Ejection _OST Processing Support Definition: This bit is set if OSPM will evaluate the _OST object defined under a device when processing insertion and ejection source event codes.

The checking should be done in address mapping time instead of runtime to avoid too much error reporting in runtime.
