samsung-laptop: enable better lid handling
Some Samsung laptops with SABI3 delay the sleep for 10 seconds after
the lid is closed and do not wake up from sleep after the lid is opened.
A SABI command is needed to enable the better behavior.
Command = 0x6e, d0 = 0x81 enables this behavior. Returns d0 = 0x01.
Command = 0x6e, d0 = 0x80 disables this behavior. Returns d0 = 0x00.
Command = 0x6d and any d0 queries the state. This returns:
d0 = 0x00000*01, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is enabled.
d0 = 0x00000*00, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is disabled.
Where * is 0 - laptop has never slept or hibernated after switch on,
1 - laptop has hibernated just before,
2 - laptop has slept just before.
Patch addresses bug https://bugzilla.kernel.org/show_bug.cgi?id=75901 .
It adds a sysfs attribute lid_handling with a description and also an
addition to the quirks structure to enable the mode by default.
A user with another laptop in the bug report says that "power button has
to be pressed twice to wake the machine" when he or she enabled the mode
manually using the SABI command. Therefore, it is enabled by default
only for the single laptop that I have tested.

cxl: Export optional AFU configuration record in sysfs
An AFU may optionally contain one or more PCIe like configuration records, which can be used to identify the AFU. This patch adds support for exposing the raw config space and the vendor, device and class code under sysfs. These will appear in a subdirectory of the AFU device corresponding with the configuration record number, e.g. cat /sys/class/cxl/afu0.0/cr0/vendor 0x1014 cat /sys/class/cxl/afu0.0/cr0/device 0x4350 cat /sys/class/cxl/afu0.0/cr0/class 0x120000 hexdump -C /sys/class/cxl/afu0.0/cr0/config 00000000 14 10 50 43 00 00 00 00 06 00 00 12 00 00 00 00 |..PC............| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000100 These files behave in much the same way as the equivalent files for PCI devices, with one exception being that the config file is currently read-only and restricted to the root user. It is not necessarily required to be this strict, but we currently do not have a compelling use-case to make it writable and/or world-readable, so I erred on the side of being restrictive.

usb: patches for v3.20 merge window
Here's the big pull request for Gadgets and PHYs. It's a total of 217 non-merge commits with pretty much everything being touched. The most important bits are a ton of new documentation for almost all usb gadget functions, a new isp1760 UDC driver, several improvements to the old net2280 UDC driver, and some minor tracepoint improvements to dwc3.

iio: add driver for Freescale MMA9553
Add support for Freescale MMA9553L Intelligent Pedometer Platform. The following functionalities are supported: - step counter (counts the number of steps using a HW register) - step detector (generates an iio event at every step the user takes) - activity recognition (rest, walking, jogging, running) - speed - calories - distance To get accurate pedometer results, the user's height, weight and gender need to be configured. The specifications can be downloaded from: http://www.freescale.com/files/sensors/doc/ref_manual/MMA955xLSWRM.pdf http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org> |

iio: core: Introduce IIO_CHAN_INFO_DEBOUNCE_COUNT and _TIME
The pedometer needs to filter out false steps that might be generated by tapping the foot, sitting, etc. To do that it computes the number of steps that occur in a given time and decides the user is moving only if this value is over a threshold. E.g.: the user starts moving only if he takes 4 steps in 3 seconds. This filter is applied only when the user starts moving. A device that has such pedometer functionality is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf. To export this feature, this patch introduces IIO_CHAN_INFO_DEBOUNCE_COUNT and IIO_CHAN_INFO_DEBOUNCE_TIME. For the pedometer, in_steps_debounce_count will specify the number of steps that need to occur in in_steps_debounce_time seconds so that the pedometer decides the user is moving.

cxl: Add ability to reset the card
Adds reset to sysfs which will PERST the card. If load_image_on_perst is set to "user" or "factory", the PERST will cause that image to be loaded. load_image_on_perst is set to "user" for production. "none" could be used for debugging. The PSL trace arrays are preserved which then can be read through debugfs. PERST also triggers CAPP recovery. An HMI comes in, which is handled by EEH. EEH unbinds the driver, calls into Sapphire to reinitialize the PHB, then rebinds the driver.

cxl: Add image control to sysfs
load_image_on_perst identifies whether a PERST will cause the image to be flashed to the card. And if so, which image. Valid entries are: "none", "user" and "factory". A value of "none" means PERST will not cause the image to be flashed. A power cycle to the pcie slot is required to load the image. "user" loads the user provided image and "factory" loads the factory image upon PERST. sysfs updates the cxl struct in the driver then calls cxl_update_image_control to write the vals in the VSEC.

perf Documentation: Add event parameters
Event parameters are a basic way for partial events to be specified in sysfs with per-event names given to the fields that need to be filled in when using a particular event. It is intended for supporting cases where the single 'cpu' parameter is insufficient. For example, POWER 8 has events for physical sockets/cores/cpus that are accessible from with virtual machines. To keep using the single 'cpu' parameter we'd need to perform a mapping between Linux's cpus and the physical machine's cpus (in this case Linux is running under a hypervisor). This isn't possible because bindings between our cpus and physical cpus may not be fixed, and we probably won't have a "cpu" on each physical cpu.

First round of IIO new drivers, cleanups and functionality for the 3.20 cycle take 2
Updated pull request with Daniel's fix on top for the power management
Kconfig changes that had snuck in since last update of the IIO tree
worked it's way through from mainline.
Original pull message
New device support
* jsa1212 proxmity / ambient light sensor
* SM08500 supported added to the kxcjk-1013 accelerometer driver
* KMX61 Accelerometer/Magnetometer. This took a somewhat rocky path
being first merged, then reverted for a rewrite after a discussion of
how to support additional functionality and finally being merged prior
to some last reviews coming in, with resultant follow up patches.
* Freescale mma9551l driver (minor follow up warning supression patch).
* Semtech SX9500 proximity device driver.
* ak8975 gains support for ak09911 and ak09912 and drop the standalone driver
for the ak09911.
New functionality
* Dummy driver gains some virtual registers making it more flexible.
* IIO_ACTIVITY channel types, with modifiers running, walking etc. This is
to support on chip motion clasifiers. As such it is in the form of a
confidence percentage. The only devices so far only do binary decisions
but this gives us room when other devices give more nuanced clasification.
* IIO_EV_DIR_NONE type for events where there is no obvious direction.
First case is step detection.
* IIO_STEPS channel type for pedometers.
* ENABLE mask element used to control turning on counting types such as
the pedometer that need a 'start point'.
* INSTANCE event type to support things that happen once.
* info element for height calibration (used in various motion estimation
algorithms). Note heigh tof use
* dummy driver demonstration of the use of all the new bits above.
* event monitor support for the new events.
* inv_mpu6050 gains an i2c mux to allow bypassing the device to access
additional devices connected on the other side of it. Note that in
Windows these are handled by firmware on the device and not exposed
directly.
* inv_mpu6050 gains ACPI enumeration.
* inkern interface gains iio_write_channel_raw to allow in kernel users
of DAC functionality via a simple wrapper.
* Document input current readings in the ABI docs.
* Add an error message when we get an out of range error in device tree
processing for the in kernel interfaces. Basically a device tree debugging
aid.
* Add a sanity check that a scan index for a channel is unique during
registration. There to help catch bugs as this should never happen
in a bug free driver.
Cleanups and fixlets
A rework of buffer registration from Lars - a precursor to some other
upcoming new stuff (a few patches from others rolled in here as well).
* Ensure all drivers register the same channels for the device and buffer.
* Move buffer registration into the core rather than using the old
two step approach. Now we have simple ways of using a unified set channels
for both without requiring channels be exposed by both interface, this
removes a fair bit of boilerplate.
* Stop sca3000 and ad5933 (both in staging) enabling buffer channels by
default. It has long be convention in IIO to startup with no channels
enabled and leave it up to userspace to say what goes in the buffer.
Getting rid of these allows us to drop export of iio_scan_mask_set.
* Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used
for a while.
* Allocate standard buffer attributes in the core rather than in every
driver with a buffer.
* Make the length attribute read only when a driver is not able to set
the length.
* Drop the get_length callback for buffers as it is already available in
struct iio_buffer.
* Drop an unused arguement form iio_kfifo_allocate and add devm allocator
for it.
* some kconfig entries gain anotation with the resulting module name.
* Fix a resulting compile issue in dummy driver due to a stub taking
wrong parameters as a result of the above rework.
* Fix an off by 2 error in copying the core assigned buffer attributes.
Other cleanups,
* Trivial space before comma fixups.
* ak8975 fixlets - none critical. Rework to allow more device support.
* Drop unnecessary sizeof(u8) calls.
* bmp280 - refactor the compensation code to reduce copy operations and
code length. A second patch futher optimized this and performed some
other minor cleanups.
* kxcjk-1013 - various power control cleanups to avoid unnecessary enable
/ disable of device. Make sure it is only controlled at all if CONFIG_PM
is enabled. Also som cleanups of error paths.
* Small cleanups in adf4530 driver - pointless message and unnecessary braces.
* Clarifiy the proximity ABI docs to make it clear it should get bigger
as we move futher away.
* Drop a misleading comment form industrialio-core.c
* Trivial white space cleanups.
* sca3000 looses an unused debug function.
* Fix char unsigned ordering in ad8366
* Increase the sleep time in ad9523 to make it predictable (value didn't
really matter so make it more than 20 msecs)
* mxs-lradc touchscreen property cleanups in device tree are fixed to ensure
the meet all the 'interesting' documentation.
* A couple of cleanups for the staging ad5933 driver to avoid unnecessary
conversion to a processed temperature vlaue in kernel and remove
platform data form the state structure as not needed after probe.
* Fix a wrong scale factor in the docs.
Misc
* Add IIO include files to the maintainers entry.

* inkern interface gains iio_write_channel_raw to allow in kernel users
of DAC functionality via a simple wrapper.
* Document input current readings in the ABI docs.
* Add an error message when we get an out of range error in device tree
processing for the in kernel interfaces. Basically a device tree debugging
aid.
* Add a sanity check that a scan index for a channel is unique during
registration. There to help catch bugs as this should never happen
in a bug free driver.
Cleanups and fixlets
A rework of buffer registration from Lars - a precursor to some other
upcoming new stuff (a few patches from others rolled in here as well).
* Ensure all drivers register the same channels for the device and buffer.
* Move buffer registration into the core rather than using the old
two step approach. Now we have simple ways of using a unified set channels
for both without requiring channels be exposed by both interface, this
removes a fair bit of boilerplate.
* Stop sca3000 and ad5933 (both in staging) enabling buffer channels by
default. It has long be convention in IIO to startup with no channels
enabled and leave it up to userspace to say what goes in the buffer.
Getting rid of these allows us to drop export of iio_scan_mask_set.
* Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used
for a while.
* Allocate standard buffer attributes in the core rather than in every
driver with a buffer.
* Make the length attribute read only when a driver is not able to set
the length.
* Drop the get_length callback for buffers as it is already available in
struct iio_buffer.
* Drop an unused arguement form iio_kfifo_allocate and add devm allocator
for it.
* some kconfig entries gain anotation with the resulting module name.
* Fix a resulting compile issue in dummy driver due to a stub taking
wrong parameters as a result of the above rework.
* Fix an off by 2 error in copying the core assigned buffer attributes.
Other cleanups,
* Trivial space before comma fixups.
* ak8975 fixlets - none critical. Rework to allow more device support.
* Drop unnecessary sizeof(u8) calls.
* bmp280 - refactor the compensation code to reduce copy operations and
code length. A second patch futher optimized this and performed some
other minor cleanups.
* kxcjk-1013 - various power control cleanups to avoid unnecessary enable
/ disable of device. Make sure it is only controlled at all if CONFIG_PM
is enabled. Also som cleanups of error paths.
* Small cleanups in adf4530 driver - pointless message and unnecessary braces.
* Clarifiy the proximity ABI docs to make it clear it should get bigger
as we move futher away.
* Drop a misleading comment form industrialio-core.c
* Trivial white space cleanups.
* sca3000 looses an unused debug function.
* Fix char unsigned ordering in ad8366
* Increase the sleep time in ad9523 to make it predictable (value didn't
really matter so make it more than 20 msecs)
* mxs-lradc touchscreen property cleanups in device tree are fixed to ensure
the meet all the 'interesting' documentation.
* A couple of cleanups for the staging ad5933 driver to avoid unnecessary
conversion to a processed temperature vlaue in kernel and remove
platform data form the state structure as not needed after probe.
* Fix a wrong scale factor in the docs.
Misc
* Add IIO include files to the maintainers entry.

livepatch: kernel: add support for live patching
This commit introduces code for the live patching core. It implements an ftrace-based mechanism and kernel interface for doing live patching of kernel and kernel module functions. It represents the greatest common functionality set between kpatch and kgraft and can accept patches built using either method. This first version does not implement any consistency mechanism that ensures that old and new code do not run together. In practice, ~90% of CVEs are safe to apply in this way, since they simply add a conditional check. However, any function change that can not execute safely with the old version of the function can _not_ be safely applied in this version.

Staging patches for 3.19-rc1
Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

the last couple of development cycles.
The most important part of it to me is the introduction of a unified
interface for accessing device properties provided by platform
firmware. It works with Device Trees and ACPI in a uniform way and
drivers using it need not worry about where the properties come
from as long as the platform firmware (either DT or ACPI) makes
them available. It covers both devices and "bare" device node
objects without struct device representation as that turns out to
be necessary in some cases. This has been in the works for quite
a few months (and development cycles) and has been approved by
all of the relevant maintainers.
On top of that, some drivers are switched over to the new interface
(at25, leds-gpio, gpio_keys_polled) and some additional changes are
made to the core GPIO subsystem to allow device drivers to manipulate
GPIOs in the "canonical" way on platforms that provide GPIO information
in their ACPI tables, but don't assign names to GPIO lines (in which
case the driver needs to do that on the basis of what it knows about
the device in question). That also has been approved by the GPIO
core maintainers and the rfkill driver is now going to use it.
Second is support for hardware P-states in the intel_pstate driver.
It uses CPUID to detect whether or not the feature is supported by
the processor in which case it will be enabled by default. However,
it can be disabled entirely from the kernel command line if necessary.
Next is support for a platform firmware interface based on ACPI
operation regions used by the PMIC (Power Management Integrated
Circuit) chips on the Intel Baytrail-T and Baytrail-T-CR platforms.
That interface is used for manipulating power resources and for
thermal management: sensor temperature reporting, trip point setting
and so on.
Also the ACPI core is now going to support the _DEP configuration
information in a limited way. Basically, _DEP it supposed to reflect
off-the-hierarchy dependencies between devices which may be very
indirect, like when AML for one device accesses locations in an
operation region handled by another device's driver (usually, the
device depended on this way is a serial bus or GPIO controller).
The support added this time is sufficient to make the ACPI battery
driver work on Asus T100A, but it is general enough to be able to
cover some other use cases in the future.
Finally, we have a new cpufreq driver for the Loongson1B processor.
In addition to the above, there are fixes and cleanups all over the
place as usual and a traditional ACPICA update to a recent upstream
release.
As far as the fixes go, the ACPI LPSS (Low-power Subsystem) driver
for Intel platforms should be able to handle power management of
the DMA engine correctly, the cpufreq-dt driver should interact
with the thermal subsystem in a better way and the ACPI backlight
driver should handle some more corner cases, among other things.
On top of the ACPICA update there are fixes for race conditions
in the ACPICA's interrupt handling code which might lead to some
random and strange looking failures on some systems.
In the cleanups department the most visible part is the series
of commits targeted at getting rid of the CONFIG_PM_RUNTIME
configuration option. That was triggered by a discussion
regarding the generic power domains code during which we realized
that trying to support certain combinations of PM config options
was painful and not really worth it, because nobody would use them
in production anyway. For this reason, we decided to make
CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and that lead to the
conclusion that the latter became redundant and CONFIG_PM could
be used instead of it. The material here makes that replacement
in a major part of the tree, but there will be at least one more
batch of that in the second part of the merge window.
Specifics:
- Support for retrieving device properties information from ACPI
_DSD device configuration objects and a unified device properties
interface for device drivers (and subsystems) on top of that.
As stated above, this works with Device Trees and ACPI and allows
device drivers to be written in a platform firmware (DT or ACPI)
agnostic way. The at25, leds-gpio and gpio_keys_polled drivers
are now going to use this new interface and the GPIO subsystem
is additionally modified to allow device drivers to assign names
to GPIO resources returned by ACPI _CRS objects (in case _DSD is
not present or does not provide the expected data). The changes
in this set are mostly from Mika Westerberg, Rafael J Wysocki,
Aaron Lu, and Darren Hart with some fixes from others (Fabio Estevam,
Geert Uytterhoeven).
- Support for Hardware Managed Performance States (HWP) as described
in Volume 3, section 14.4, of the Intel SDM in the intel_pstate
driver. CPUID is used to detect whether or not the feature is
supported by the processor. If supported, it will be enabled
automatically unless the intel_pstate=no_hwp switch is present in
the kernel command line. From Dirk Brandewie.
- New Intel Broadwell-H ID for intel_pstate (Dirk Brandewie).
- Support for firmware interface based on ACPI operation regions
used by the PMIC chips on the Intel Baytrail-T and Baytrail-T-CR
platforms for power resource control and thermal management
(Aaron Lu).
- Limited support for retrieving off-the-hierarchy dependencies
between devices from ACPI _DEP device configuration objects
and deferred probing support for the ACPI battery driver based
on the _DEP information to make that driver work on Asus T100A
(Lan Tianyu).
- New cpufreq driver for the Loongson1B processor (Kelvin Cheung).
- ACPICA update to upstream revision 20141107 which only affects
tools (Bob Moore).
- Fixes for race conditions in the ACPICA's interrupt handling
code and in the ACPI code related to system suspend and resume
(Lv Zheng and Rafael J Wysocki).
- ACPI core fix for an RCU-related issue in the ioremap() regions
management code that slowed down significantly after CPUs had
been allowed to enter idle states even if they'd had RCU callbakcs
queued and triggered some problems in certain proprietary graphics
driver (and elsewhere). The fix replaces synchronize_rcu() in
that code with synchronize_rcu_expedited() which makes the issue
go away. From Konstantin Khlebnikov.
- ACPI LPSS (Low-Power Subsystem) driver fix to handle power
management of the DMA engine included into the LPSS correctly.
The problem is that the DMA engine doesn't have ACPI PM support
of its own and it simply is turned off when the last LPSS device
having ACPI PM support goes into D3cold. To work around that,
the PM domain used by the ACPI LPSS driver is redesigned so at
least one device with ACPI PM support will be on as long as the
DMA engine is in use. From Andy Shevchenko.
- ACPI backlight driver fix to avoid using it on "Win8-compatible"
systems where it doesn't work and where it was used by default by
mistake (Aaron Lu).
- Assorted minor ACPI core fixes and cleanups from Tomasz Nowicki,
Sudeep Holla, Huang Rui, Hanjun Guo, Fabian Frederick, and
Ashwin Chaugule (mostly related to the upcoming ARM64 support).
- Intel RAPL (Running Average Power Limit) power capping driver
fixes and improvements including new processor IDs (Jacob Pan).
- Generic power domains modification to power up domains after
attaching devices to them to meet the expectations of device
drivers and bus types assuming devices to be accessible at
probe time (Ulf Hansson).
- Preliminary support for controlling device clocks from the
generic power domains core code and modifications of the
ARM/shmobile platform to use that feature (Ulf Hansson).
- Assorted minor fixes and cleanups of the generic power
domains core code (Ulf Hansson, Geert Uytterhoeven).
- Assorted minor fixes and cleanups of the device clocks control
code in the PM core (Geert Uytterhoeven, Grygorii Strashko).
- Consolidation of device power management Kconfig options by making
CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and removing the latter
which is now redundant (Rafael J Wysocki and Kevin Hilman). That
is the first batch of the changes needed for this purpose.
- Core device runtime power management support code cleanup related
to the execution of callbacks (Andrzej Hajda).
- cpuidle ARM support improvements (Lorenzo Pieralisi).
- cpuidle cleanup related to the CPUIDLE_FLAG_TIME_VALID flag and
a new MAINTAINERS entry for ARM Exynos cpuidle (Daniel Lezcano and
Bartlomiej Zolnierkiewicz).
- New cpufreq driver callback (->ready) to be executed when the
cpufreq core is ready to use a given policy object and cpufreq-dt
driver modification to use that callback for cooling device
registration (Viresh Kumar).
- cpufreq core fixes and cleanups (Viresh Kumar, Vince Hsu,
James Geboski, Tomeu Vizoso).
- Assorted fixes and cleanups in the cpufreq-pcc, intel_pstate,
cpufreq-dt, pxa2xx cpufreq drivers (Lenny Szubowicz, Ethan Zhao,
Stefan Wahren, Petr Cvek).
- OPP (Operating Performance Points) framework modification to
allow OPPs to be removed too and update of a few cpufreq drivers
(cpufreq-dt, exynos5440, imx6q, cpufreq) to remove OPPs (added
during initialization) on driver removal (Viresh Kumar).
- Hibernation core fixes and cleanups (Tina Ruchandani and
Markus Elfring).
- PM Kconfig fix related to CPU power management (Pankaj Dubey).
- cpupower tool fix (Prarit Bhargava).

iio: core: Introduce IIO_CHAN_INFO_CALIBHEIGHT
Some devices need the height of the user to compute various parameters. One of this devices is Freescale's MMA9553L (http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf) that needs the height of the user to compute the stride length which is used further to determine distance, speed and activity type.

iio: core: Introduce STEPS channel, ENABLE mask and INSTANCE event
These changes are needed to support the functionality of a pedometer. A pedometer has two basic functionalities: step counter and step detector. The step counter needs to be enabled and then it will count the steps in its hardware register. Whenever the application needs to check the step count, it will read the step counter register. To support the step counter a new channel type STEPS is added. Since the pedometer needs to be enabled first so that the hardware can count and store the steps, we need a specific ENABLE channel info mask. The step detector will generate an interrupt each time a step is detected. To support this functionality we add a new event type INSTANCE. For more information on the Android requirements for step counter and step detector see: http://source.android.com/devices/sensors/composite_sensors.html#counter and http://source.android.com/devices/sensors/composite_sensors.html#detector. A device that has the pedometer functionality this interface needs to support is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org> |

iio: core: Introduce IIO_ACTIVITY channel
This channel will be used for exposing information about
activity composite sensors. Activities supported so far:
* running
* jogging
* walking
* still
THRESHOLD event is used to signal a change in the activity
state.
We associate a confidence interval for each activity expressed
as a percentage from 0 to 100.
* 0, means the sensor IS NOT reporting that activity.
* 100, means the sensor IS reporting that activity.
Users of this interface have two possible means to gather
information about the ongoing activities.
1. Event based, via event file descriptor
* sensor may report an event when ENTERING an activity or LEAVING
an activity based on a threshold value.
* drivers will wake up applications waiting data on the event fd
2. Polling, by reading the sysfs associated attribute files:
* /sys/bus/iio/devices/iio:device0/in_activity_running_input
expressed as percentage confidence value from 0 to 100.
This will offer an interface for Android significant motion
composite sensor defined here:
http://source.android.com/devices/sensors/composite_sensors.html
Activities listed above are supported by Freescale's MMA9553 sensor:

drivers: base: support cpu cache information interface to userspace via sysfs
This patch adds initial support for providing processor cache information to userspace through sysfs interface. This is based on already existing implementations(x86, ia64, s390 and powerpc) and hence the interface is intended to be fully compatible. The main purpose of this generic support is to avoid further code duplication to support new architectures and also to unify all the existing different implementations. This implementation maintains the hierarchy of cache objects which reflects the system's cache topology. Cache devices are instantiated as needed as CPUs come online. The cache information is replicated per-cpu even if they are shared. A per-cpu array of cache information maintained is used mainly for sysfs-related book keeping. It also implements the shared_cpu_map attribute, which is essential for enabling both kernel and user-space to discover the system's overall cache topology. This patch also add the missing ABI documentation for the cacheinfo sysfs interface already, which is well defined and widely used.

PCI: Allow numa_node override via sysfs
NUMA systems with ACPI normally describe the physical topology via _PXM methods. But many BIOSes don't implement _PXM, which leaves the kernel with no way to discover the device topology, which reduces performance because we can't put memory and processes close to the device. The NUMA node of a PCI device is already exported in the sysfs "numa_node" file. Make that file writable so users can workaround the lack of _PXM methods in the BIOS. For example: echo 3 > /sys/devices/pci0000:ff/0000:03:1f.3/numa_node sets the node for PCI device 0000:03:1f.3. Writing the file emits a FW_BUG warning to encourage users to request firmware updates. It also taints the kernel with TAINT_FIRMWARE_WORKAROUND because overriding the node incorrectly can cause performance issues.

into the python binding (Jiri Olsa)
- Document sysfs events/ interfaces (Cody P Schafer)
- Fix typos in perf/Documentation (Masanari Iida)
- Add missing 'struct option' forward declaration (Arnaldo Carvalho
de Melo)
- Add option to copy events when queuing for sorting across cpu
buffers and enable it for 'perf kvm stat live', to avoid having
events left in the queue pointing to the ring buffer be rewritten
in high volume sessions. (Alexander Yarygin, improving work done
by David Ahern):
- Do not include a struct hists per perf_evsel, untangling the
histogram code from perf_evsel, to pave the way for exporting a
minimalistic tools/lib/api/perf/ library usable by tools/perf and
initially by the rasd daemon being developed by Borislav Petkov,
Robert Richter and Jean Pihet. (Arnaldo Carvalho de Melo)
- Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
thread maps mean syswide monitoring, reducing the boilerplate for
tools that only want system wide mode. (Arnaldo Carvalho de Melo)
- Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
should be just a front end for exit + free (Arnaldo Carvalho de
Melo)
- Add support to new style format of kernel PMU event. (Kan Liang)

"This is the core block IO pull request for 3.18. Apart from the new

and cleanups.
- blk-mq timeout updates and fixes from Christoph.
- Removal of REQ_END, also from Christoph. We pass it through the
->queue_rq() hook for blk-mq instead, freeing up one of the request
bits. The space was overly tight on 32-bit, so Martin also killed
REQ_KERNEL since it's no longer used.
- blk integrity updates and fixes from Martin and Gu Zheng.
- Update to the flush machinery for blk-mq from Ming Lei. Now we
have a per hardware context flush request, which both cleans up the
code should scale better for flush intensive workloads on blk-mq.
- Improve the error printing, from Rob Elliott.
- Backing device improvements and cleanups from Tejun.
- Fixup of a misplaced rq_complete() tracepoint from Hannes.
- Make blk_get_request() return error pointers, fixing up issues
where we NULL deref when a device goes bad or missing. From Joe
Lawrence.
- Prep work for drastically reducing the memory consumption of dm
devices from Junichi Nomura. This allows creating clone bio sets
without preallocating a lot of memory.
- Fix a blk-mq hang on certain combinations of queue depths and
hardware queues from me.
- Limit memory consumption for blk-mq devices for crash dump
scenarios and drivers that use crazy high depths (certain SCSI
shared tag setups). We now just use a single queue and limited
depth for that"

zram: use notify_free to account all free notifications
`notify_free' device attribute accounts the number of slot free
notifications and internally represents the number of zram_free_page()
calls. Slot free notifications are sent only when device is used as a
swap device, hence `notify_free' is used only for swap devices. Since

zram: report maximum used memory
Normally, zram user could get maximum memory usage zram consumed via polling mem_used_total with sysfs in userspace. But it has a critical problem because user can miss peak memory usage during update inverval of polling. For avoiding that, user should poll it with shorter interval(ie, 0.0000000001s) with mlocking to avoid page fault delay when memory pressure is heavy. It would be troublesome. This patch adds new knob "mem_used_max" so user could see the maximum memory usage easily via reading the knob and reset it via "echo 0 > /sys/block/zram0/mem_used_max".

zram: zram memory size limitation
Since zram has no control feature to limit memory usage, it makes hard to manage system memrory. This patch adds new knob "mem_limit" via sysfs to set up the a limit so that zram could fail allocation once it reaches the limit. In addition, user could change the limit in runtime so that he could manage the memory more dynamically. Initial state is no limit so it doesn't break old behavior.

memory-hotplug: add sysfs valid_zones attribute
Currently memory-hotplug has two limits: 1. If the memory block is in ZONE_NORMAL, you can change it to ZONE_MOVABLE, but this memory block must be adjacent to ZONE_MOVABLE. 2. If the memory block is in ZONE_MOVABLE, you can change it to ZONE_NORMAL, but this memory block must be adjacent to ZONE_NORMAL. With this patch, we can easy to know a memory block can be onlined to which zone, and don't need to know the above two limits. Updated the related Documentation.

Staging patches for 3.18-rc1
Here is the big staging patch set for 3.18-rc1. Once again, we are deleting more code than we added, with something like 150000 lines deleted overall. Some of this is due to drivers being added to the networking tree, so the old versions are removed here, but even then, the overall difference is quite good.

PCI/MSI: Add "msi_bus" sysfs MSI/MSI-X control for endpoints
The "msi_bus" sysfs file for bridges sets a bus flag to allow or disallow future driver requests for MSI or MSI-X. Previously, the sysfs file existed for endpoints but did nothing. Add "msi_bus" support for endpoints, so an administrator can prevent the use of MSI and MSI-X for individual devices. Note that as for bridges, these changes only affect future driver requests for MSI or MSI-X, so drivers may need to be reloaded. Add documentation for the "msi_bus" sysfs file.

f2fs: give an option to enable in-place-updates during fsync to users
If user wrote F2FS_IPU_FSYNC:4 in /sys/fs/f2fs/ipu_policy, f2fs_sync_file only starts to try in-place-updates. And, if the number of dirty pages is over /sys/fs/f2fs/min_fsync_blocks, it keeps out-of-order manner. Otherwise, it triggers in-place-updates. This may be used by storage showing very high random write performance. For example, it can be used when, Seq. writes (Data) + wait + Seq. writes (Node) is pretty much slower than, Rand. writes (Data) Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle.
Maintainer Updates * Add 3 designated reviewers for IIO. Lars, Peter and Hartmut have been actively reviewing a lot of patches for a while now so this reflects the status quo. These three are probably the only reason I keep my head above the water! New drivers and device support * max5821 DAC * Rockchip SARADC * TI ADC128S052 ADC * BMC150 Accelerometer * exynos ADC driver gains support for s3c24xx and s3c64xx parts. * kxcjk-1013 gainst range control and runtime PM support to drive down it's power usage. Driver removals * Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple basis that they drivers just provided a register write function with no compliant user space ABI whatsoever. Much better to drop them and start again for these in the fullness of time. Core Enhancements * Join together neighbouring elements in the demux units that feeds the binary interfaces. This cuts down on the number of individual copies needed when splitting out individual channels from the incoming channel scans. * Other demux related cleanups such as using roundup instead of a local implementation. Cleanups * Drop an unnecessary double setting of the owner field in xilinx adc. * Some more patches to use managed (devm) interfaces to cut down on complexity of removal code. * adis16060 coding style fixlets. * Fix some incorrect error returns in the Xilinx ADC driver. * Coding style fixlets for various accelerometer drivers. * Some sparse warning fixes to do with endianness and sign of variables. * Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer in hid-sensor-magn-3d by dropping the relevant code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJT86rcAAoJEFSFNJnE9BaIhKoQAKJ+pIpOb36k1Kjppe0PgQjG 0YCUJEte6z9RSM3s7Z47B6gm165MerYpscQW0GvTKCaxVB0GcnbE9IPYROIfZo+6 QIQbMHe9J7mYW0+qtHBxY5ItOCcVUMSwGfbXar8nFVS6266OcXP+HAau4U9WweKt GmYMuTxLdzm5JYh6C+ljv2PaRZ6B9IascF+YCrDnvkL34ojq7YpLA4QE0GcJlI4s Fz3k7UE0ckrrkAytCumjJC/zn/BSntzyUu2ctN5Z8VO6WeMyuSyFo8uxhzhoyjtm NnISm89Y2Dn5iBtb+QA/6OfOEd9MtjbALauozj70u6ONL0sYdbayNcHvhUU6lnNu hge8xlKS5MhCKtMFZ02qJM0MD/cajNt77m/QYaOoZlbuFPbREI12PtsHah6F7SJT Ad3YQ8T8rT+wzq45EqlqYE863H1OMMJulyjqUom0I8LgTijz+Exs6HWs4/qMhz6V 3T3ZwVoWSnhE4/yyRJFB/xD1P/uZIUGBP30EwlKxaiDmdxJ5X69Vlo9+AuecS3bq hRQvHSNFQG4cZEaDf/fzKGITkLv7V3oxqhg7yiSFtocj9kbF/6KyqgrUl5y7AZBL ZyW9m8OLr0K4ns8sKtRLeg9UmQ0Jxs2L1OvYtPSECAioMmMjLdij4Xt5U4Jv5ifC STIMv21b8mmNV9N8SdSo =zqHo -----END PGP SIGNATURE----- Merge tag 'iio-for-3.18a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into work-next Jonathan writes: 1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle.

nilfs2: add /sys/fs/nilfs2/features group
This patchset implements creation of sysfs groups and attributes with the purpose to show NILFS2 volume details, internal state of the driver and to manage internal state of NILFS2 driver. Sysfs is a virtual file system that exports information about devices and drivers from the kernel device model to user space, and is also used for configuration. NILFS2 is a complex file system that has segctor thread, GC thread, checkpoint/snapshot model and so on. Sysfs namespace provides native and easy way for: (1) getting info and statistics about volume state; (2) getting info and configuration of internal subsystems (segctor thread); (3) snapshots management. Suggested patchset provides basis for managing segctor thread behaviour and manipulation by snapshots. Currently, it informs only about segctor thread's internal parameters and about mounted snapshots. But sysfs interface can provide easy and simple way for deep management of segctor thread and snapshots. This patchset provides opportunity to manage interval of periodical update of superblock (in seconds). Default value is 10 seconds. Now a user can increase this value by means of nilfs2/<device>/superblock/sb_update_frequency attribute in the case of necessity. Also the patchset provides opportunity to get information easily about key volumes's parameters (free blocks, superblock write count, superblock update frequency, latest segment info, dirty data blocks count, count of clean segments, count of dirty segments and so on) in real time manner. Such information can be used in scripts for subtle management of filesystem. Implemented functionality creates such groups: (1) /sys/fs/nilfs2 - root group (2) /sys/fs/nilfs2/features - group contains attributes that describe NILFS file system driver features (3) /sys/fs/nilfs2/<device> - group contains attributes that describe file system partition's details (4) /sys/fs/nilfs2/<device>/superblock - group contains attributes that describe superblock's details (5) /sys/fs/nilfs2/<device>/segctor - group contains attributes that describe segctor thread activity details (6) /sys/fs/nilfs2/<device>/segments - group contains attributes that describe details about volume's segments (7) /sys/fs/nilfs2/<device>/checkpoints - group contains attributes that describe details about volume's checkpoints (8) /sys/fs/nilfs2/<device>/mounted_snapshots - group contains group for every mounted snapshot (9) /sys/fs/nilfs2/<device>/mounted_snapshots/<snapshot> - group contains details about mounted snapshot This patch (of 9): This patch adds code of creation /sys/fs/nilfs2 group and /sys/fs/nilfs2/features group. The features group contains attributes that describe NILFS file system driver features: (1) revision - show current revision of NILFS file system driver. There are two formats of timestamp output - seconds and human-readable format. Every showed timestamp has two sysfs files (time-<xxx> and time-<xxx>-secs). One sysfs file (time-<xxx>) shows time in human-readable format. Another sysfs file (time-<xxx>-secs) shows time in seconds. It was reported by Michael Semon that timestamp output in human-readable format should be changed from "2014-4-12 14:5:38" to "2014-04-12 14:05:38". Second version of the patch fixes this issue.

ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
platforms. Among the bigger ones:
* Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
lacked active support for quite a while, and after asking around nobody
showed interest in keeping them around. If needed, they could be
resurrected in the future but it's more likely that we would prefer
reintroduction of them as DT and multiplatform-enabled platforms
instead.
* OMAP4 controller code register define diet. They defined a lot of registers
that were never actually used, etc.
* Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
to drivers/soc so it can be shared with 64-bit code. This also converts them
over to traditional driver models where possible.
* Removal of legacy gpio-samsung driver, since the last users have been
removed (moved to pinctrl)
Plus a bunch of smaller changes for various platforms that sort of
dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some misc
cleanups, etc.

Input: wacom - update the ABI doc according to latest changes
Now the devices show up under hid no matter the connection (for USB and Bluetooth, not serial nor i2c). The USB devices can now be easily found under /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n> The Bluetooth devices could also be found under this path since their inclusion (April 2010), so this patch fixes the non-precise "hidraw*" path for them. The ABI has been unified while setting the LEDs and OLEDs. So Bluetooth devices lost their own LED selector but use the USB sysfs attribute. For OLEDs, Bluetooth devices handle only 1-bit images instead of 4 for USB. The documentation has been updated to match this.
