* PM / devfreq: allow sysfs governor node to switch governorNishanth Menon2012-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | This allows us to select governor runtime from the default configuration without having to rebuild kernel or the devfreq driver using the sysfs node: /sys/class/devfreq/.../governor cat of the governor will return valid governor and an echo 'governor_name'>governor will switch governor Cc: Rajagopal Venkat <rajagopal.venkat@linaro.org> Cc: MyungJoo Ham <myungjoo.ham@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: "Rafael J.

* PM / devfreq: Add sysfs node to expose available frequenciesNishanth Menon2012-11-201-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | devfreq governors such as ondemand are controlled by a min and max frequency, while governors like userspace governor allow us to set a specific frequency. However, for the same specific device, depending on the SoC, the available frequencies can vary. So expose the available frequencies as a snapshot over sysfs to allow informed decisions. This was inspired by cpufreq framework's equivalent for similar usage sysfs node: scaling_available_frequencies.

* PM / devfreq: Add current freq callback in device profileRajagopal Venkat2012-11-151-1/+10
| | | | | | | | | | | | Devfreq returns governor predicted frequency as current frequency via sysfs interface. But device may not support all frequencies that governor predicts. So add a callback in device profile to get current freq from driver. Also add a new sysfs node to expose governor predicted next target frequency.

* PM / devfreq: Core updates to support devices which can idleRajagopal Venkat2012-11-151-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare devfreq core framework to support devices which can idle. When device idleness is detected perhaps through runtime-pm, need some mechanism to suspend devfreq load monitoring and resume back when device is online. Present code continues monitoring unless device is removed from devfreq core. This patch introduces following design changes, - use per device work instead of global work to monitor device load. This enables suspend/resume of device devfreq and reduces monitoring code complexity. - decouple delayed work based load monitoring logic from core by introducing helpers functions to be used by governors. This provides flexibility for governors either to use delayed work based monitoring functions or to implement their own mechanism. - devfreq core interacts with governors via events to perform specific actions. These events include start/stop devfreq. This sets ground for adding suspend/resume events. The devfreq apis are not modified and are kept intact.

This new interface provides a standard and platform neutral way for users to obtain the description text stored in the ACPI _STR method. If no _STR method exists for the device, no sysfs 'description' file will be created. The 'description' file will be located in the /sys/devices/ directory using the device's path. /sys/device/<bus>/<bridge path>/<device path>.../firmware_node/description Example: /sys/devices/pci0000:00/0000:00.07.0/0000:0e:00.0/firmware_node/description It can also be located using the ACPI device path, for example: /sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/PNP0A08:00/device:13/device:15/description /sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/ACPI0004:01/ACPI0007:02/description Execute the 'cat' command on the 'description' file to obtain the description string for that device. This patch also includes documentation describing how the new sysfs interface works Changes from v1-v2 based on comments by Len Brown and Fengguang Wu * Removed output "No Description" and leaving a NULL attribute if the _STR method failed to evaluate. * In acpi_device_remove_files() removed the redundent check of dev->pnp.str_obj before calling free.

There's nothing special about snapshot creation that makes it advantageous to do from the kernel, so I'd like to remove the create_snap sysfs interface. That is, /sys/bus/rbd/devices/<id>/create_snap would be removed. Does anyone rely on the sysfs interface for creating rbd snapshots? If so, how hard would it be to replace with: rbd snap create pool/image@snap Is there any benefit to the sysfs interface that I'm missing? Josh This patch implements this proposal, removing the code that implements the "snap_create" sysfs interface for rbd images. As a result, quite a lot of other supporting code goes away.

This patch extends the policy language with 'fowner', defines an appraise policy, which appraises all files owned by root, and defines 'ima_appraise_tcb', a new boot command line option, to enable the appraise policy. Changelog v3: - separate the measure from the appraise rules in order to support measuring without appraising and appraising without measuring. - change appraisal default for filesystems without xattr support to fail - update default appraise policy for cgroups Changelog v1: - don't appraise RAMFS (Dmitry Kasatkin) - merged rest of "ima: ima_must_appraise_or_measure API change" commit (Dmtiry Kasatkin) ima_must_appraise_or_measure() called ima_match_policy twice, which searched the policy for a matching rule. Once for a matching measurement rule and subsequently for an appraisal rule. Searching the policy twice is unnecessary overhead, which could be noticeable with a large policy. The new version of ima_must_appraise_or_measure() does everything in a single iteration using a new version of ima_match_policy(). It returns IMA_MEASURE, IMA_APPRAISE mask. With the use of action mask only one efficient matching function is enough. Removed other specific versions of matching functions. Changelog: - change 'owner' to 'fowner' to conform to the new LSM conditions posted by Roberto Sassu. - fix calls to ima_log_string() Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com>

This patch adds support to acpi-cpufreq, but also includes support for Intel's dynamic acceleration. The original boost disabling sysfs file was per CPU, but acted globally. Also the naming (cpb) was at least not intuitive. So lets introduce a single file simply called "boost", which sits once in /sys/devices/system/cpu/cpufreq. This should be the only way of using this feature, so add documentation about the rationale and the usage. A following patch will re-introduce the cpb knob for compatibility reasons on AMD CPUs. Per-CPU boost switching is possible, but not trivial and is thus postponed to a later patch series. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Rafael J.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space.

For an upcoming Intel xHCI roothub, this will translate into ACPI calls to completely power off or power on the port. As a reminder, when these ports are completely powered off, the USB host and device will see a physical disconnect. All future USB device connections will be lost, and the device will not be able to signal a remote wakeup. The control sysfs file can be written to with two options: "on" - port power must be on. "off" - port must be off. The state sysfs file reports usb port's power state: "on" - powered on "off" - powered off "error" - can't get power state For now, let userspace dictate the port power off policy. Future patches may add an in-kernel policy.

In addition to that, Henrik reworked multitouch handling in order to reduce runtime memory consumption. This patchset touches code in Input subsystem as well. All the changes have been Acked by Dmitry, and we agreed to do it this way due to inter-dependencies between the patchset and subsequent changes in HID subsystem. 2) Rework, clenaups and a lot of fixes to picolcd driver by Bruno Prémont. 3) Core report descriptor handling fix which fixes resume issue on some devices, by Kevin Daughtridge 4) hidraw fixes by Alexey Khoroshilov and Ratan Nalumasu 5) wiimote driver now supports balance board, by David Herrmann. 6) Other smaller fixes and new device id additions all over the place. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (79 commits) HID: hidraw: don't deallocate memory when it is in use HID: picoLCD: optimize for inactive debugfs HID: multitouch: add support for GeneralTouch multi-touchscreen HID: Add support for Sony PS3 BD Remote Control HID: keep dev_rdesc unmodified and use it for comparisons HID: lg4ff: Minor coding style fixes in lg4ff and hid-lg HID: hid-lg4ff: Set absolute axes parametes on DFP HID: hid-lg4ff: Adjust X axis input value accordingly to selected range.

This is mainly used in low power retention states where power consumption is extremely low so higher voltage or less clean supplies can be used. Support this by providing ops for the drivers and a consumer API which allows the device to be put into bypass mode if all consumers enable it and the machine enables permission for this. This is not supported as a mode since the existing modes are rarely used due to fuzzy definition and mostly redundant with modern hardware which is able to respond promptly to load changes.
