Merge tag 'dm-4.6-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- Most attention this cycle went to optimizing blk-mq request-based DM
(dm-mq) that is used exclussively by DM multipath:
- A stable fix for dm-mq that eliminates excessive context
switching offers the biggest performance improvement (for both
IOPs and throughput).
- But more work is needed, during the next cycle, to reduce
spinlock contention in DM multipath on large NUMA systems.
- A stable fix for a NULL pointer seen when DM stats is enabled on a DM
multipath device that must requeue an IO due to path failure.
- A stable fix for DM snapshot to disallow the COW and origin devices
from being identical. This amounts to graceful failure in the face
of userspace error because these devices shouldn't ever be identical.
- Stable fixes for DM cache and DM thin provisioning to address crashes
seen if/when their respective metadata device experiences failures
that cause the transition to 'fail_io' mode.
- The DM cache 'mq' policy is now an alias for the 'smq' policy. The
'smq' policy proved to be consistently better than 'mq'. As such
'mq', with all its complex user-facing tunables, has been eliminated.
- Improve DM thin provisioning to consistently return -ENOSPC once the
thin-pool's data volume is out of space.
- Improve DM core to properly handle error propagation if
bio_integrity_clone() fails in clone_bio().
- Other small cleanups and improvements to DM core.
* tag 'dm-4.6-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (41 commits)
dm: fix rq_end_stats() NULL pointer in dm_requeue_original_request()
dm thin: consistently return -ENOSPC if pool has run out of data space
dm cache: bump the target version
dm cache: make sure every metadata function checks fail_io
dm: add missing newline between DM_DEBUG_BLOCK_STACK_TRACING and DM_BUFIO
dm cache policy smq: clarify that mq registration failure was for 'mq'
dm: return error if bio_integrity_clone() fails in clone_bio()
dm thin metadata: don't issue prefetches if a transaction abort has failed
dm snapshot: disallow the COW and origin devices from being identical
dm cache: make the 'mq' policy an alias for 'smq'
dm: drop unnecessary assignment of md->queue
dm: reorder 'struct mapped_device' members to fix alignment and holes
dm: remove dummy definition of 'struct dm_table'
dm: add 'dm_numa_node' module parameter
dm thin metadata: remove needless newline from subtree_dec() DMERR message
dm mpath: cleanup reinstate_path() et al based on code review
dm mpath: remove __pgpath_busy forward declaration, rename to pgpath_busy
dm mpath: switch from 'unsigned' to 'bool' for flags where appropriate
dm round robin: use percpu 'repeat_count' and 'current_path'
dm path selector: remove 'repeat_count' return from .select_path hook

+Qualcomm Atheros IPQ4019 TLMM block
+
+This is the Top Level Mode Multiplexor block found on the Qualcomm IPQ8019
+platform, it provides pinctrl, pinmux, pinconf, and gpiolib facilities.
+
+Required properties:
+- compatible: "qcom,ipq4019-pinctrl"
+- reg: Should be the base address and length of the TLMM block.
+- interrupts: Should be the parent IRQ of the TLMM block.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+ The first cell is the gpio pin number and the
+ second cell is used for optional parameters.
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength.
+
+Non-empty subnodes must specify the 'pins' property.
+Note that not all properties are valid for all pins.
+
+
+Valid values for qcom,pins are:
+ gpio0-gpio99
+ Supports mux, bias and drive-strength
+
+Valid values for qcom,function are:
+gpio, blsp_uart1, blsp_i2c0, blsp_i2c1, blsp_uart0, blsp_spi1, blsp_spi0
+
+Example:
+
+ tlmm: pinctrl@1000000 {
+ compatible = "qcom,ipq4019-pinctrl";
+ reg = <0x1000000 0x300000>;

+* STM32 GPIO and Pin Mux/Config controller
+
+STMicroelectronics's STM32 MCUs intregrate a GPIO and Pin mux/config hardware
+controller. It controls the input/output settings on the available pins and
+also provides ability to multiplex and configure the output of various on-chip
+controllers onto these pads.
+
+Pin controller node:
+Required properies:
+ - compatible: value should be one of the following:
+ (a) "st,stm32f429-pinctrl"
+ - #address-cells: The value of this property must be 1
+ - #size-cells : The value of this property must be 1
+ - ranges : defines mapping between pin controller node (parent) to
+ gpio-bank node (children).
+ - pins-are-numbered: Specify the subnodes are using numbered pinmux to
+ specify pins.
+
+GPIO controller/bank node:
+Required properties:
+ - gpio-controller : Indicates this device is a GPIO controller
+ - #gpio-cells : Should be two.
+ The first cell is the pin number
+ The second one is the polarity:
+ - 0 for active high
+ - 1 for active low
+ - reg : The gpio address range, relative to the pinctrl range
+ - clocks : clock that drives this bank
+ - st,bank-name : Should be a name string for this bank as specified in
+ the datasheet
+
+Optional properties:
+ - reset: : Reference to the reset controller
+
+Example:
+#include <dt-bindings/pinctrl/stm32f429-pinfunc.h>
+...
+
+ pin-controller {
+ #address-cells = <1>;
+ #size-cells = <1>;

+Contents of function subnode node:
+----------------------------------
+Subnode format
+A pinctrl node should contain at least one subnode representing the
+pinctrl group available on the machine. Each subnode will list the
+pins it needs, and how they should be configured, with regard to muxer
+configuration, pullups, drive, output high/low and output speed.
+
+ node {
+ pinmux = <PIN_NUMBER_PINMUX>;
+ GENERIC_PINCONFIG;
+ };
+
+Required properties:
+- pinmux: integer array, represents gpio pin number and mux setting.
+ Supported pin number and mux varies for different SoCs, and are defined in
+ dt-bindings/pinctrl/<soc>-pinfunc.h directly.
+ These defines are calculated as:
+ ((port * 16 + line) << 8) | function
+ With:
+ - port: The gpio port index (PA = 0, PB = 1, ..., PK = 11)
+ - line: The line offset within the port (PA0 = 0, PA1 = 1, ..., PA15 = 15)
+ - function: The function number, can be:
+ * 0 : GPIO
+ * 1 : Alternate Function 0
+ * 2 : Alternate Function 1
+ * 3 : Alternate Function 2
+ * ...
+ * 16 : Alternate Function 15
+ * 17 : Analog
+
+Optional properties:
+- GENERIC_PINCONFIG: is the generic pinconfig options to use.
+ Available options are:
+ - bias-disable,
+ - bias-pull-down,
+ - bias-pull-up,
+ - drive-push-pull,
+ - drive-open-drain,
+ - output-low
+ - output-high
+ - slew-rate = <x>, with x being:
+ < 0 > : Low speed
+ < 1 > : Medium speed
+ < 2 > : Fast speed
+ < 3 > : High speed
+
+Example:
+
+pin-controller {
+...
+ usart1_pins_a: usart1@0 {
+ pins1 {
+ pinmux = <STM32F429_PA9_FUNC_USART1_TX>;

+Regulator DT binding for MAX77620 Power management IC from Maxim Semiconductor.
+
+Device has multiple DCDC(sd[0-3] and LDOs(ldo[0-8]). The input supply
+of these regulators are defined under parent device node.
+Details of regulator properties are defined as child node under
+sub-node "regulators" which is child node of device node.
+
+Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
+for common regulator bindings used by client.
+
+Following are properties of parent node related to regulators.
+
+Optional properties:
+-------------------
+The input supply of regulators are the optional properties on the
+parent device node. The input supply of these regulators are provided
+through following properties:
+in-sd0-supply: Input supply for SD0, INA-SD0 or INB-SD0 pins.
+in-sd1-supply: Input supply for SD1.
+in-sd2-supply: Input supply for SD2.
+in-sd3-supply: Input supply for SD3.
+in-ldo0-1-supply: Input supply for LDO0 and LDO1.
+in-ldo2-supply: Input supply for LDO2.
+in-ldo3-5-supply: Input supply for LDO3 and LDO5
+in-ldo4-6-supply: Input supply for LDO4 and LDO6.
+in-ldo7-8-supply: Input supply for LDO7 and LDO8.
+
+Optional sub nodes for regulators under "regulators" subnode:
+------------------------------------------------------------
+The subnodes name is the name of regulator and it must be one of:
+ sd[0-3], ldo[0-8]
+
+Each sub-node should contain the constraints and initialization
+information for that regulator. The definition for each of these
+nodes is defined using the standard binding for regulators found at
+<Documentation/devicetree/bindings/regulator/regulator.txt>.
+
+Theres are also additional properties for SD/LDOs. These additional properties
+are required to configure FPS configuration parameters for SDs and LDOs.
+Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
+Power Sequence (FPS).
+Following are additional properties:
+
+- maxim,active-fps-source: FPS source for the regulators to get
+ enabled/disabled when system is in
+ active state. Valid values are:
+ - MAX77620_FPS_SRC_0,
+ FPS source is FPS0.
+ - MAX77620_FPS_SRC_1,
+ FPS source is FPS1
+ - MAX77620_FPS_SRC_2 and
+ FPS source is FPS2
+ - MAX77620_FPS_SRC_NONE.
+ Regulator is not controlled
+ by FPS events and it gets
+ enabled/disabled by register
+ access.
+ Absence of this property will leave
+ the FPS configuration register for that
+ regulator to default configuration.
+
+- maxim,active-fps-power-up-slot: Sequencing event slot number on which
+ the regulator get enabled when
+ master FPS input event set to HIGH.
+ Valid values are 0 to 7.
+ This is applicable if FPS source is
+ selected as FPS0, FPS1 or FPS2.
+
+- maxim,active-fps-power-down-slot: Sequencing event slot number on which
+ the regulator get disabled when master
+ FPS input event set to LOW.
+ Valid values are 0 to 7.
+ This is applicable if FPS source is
+ selected as FPS0, FPS1 or FPS2.
+
+- maxim,suspend-fps-source: This is same as property
+ "maxim,active-fps-source" but value
+ get configured when system enters in
+ to suspend state.
+
+- maxim,suspend-fps-power-up-slot: This is same as property
+ "maxim,active-fps-power-up-slot" but
+ this value get configured into FPS
+ configuration register when system
+ enters into suspend.
+ This is applicable if suspend state
+ FPS source is selected as FPS0, FPS1 or

+* ICP DAS LP-8841 SPI Controller for RTC
+
+ICP DAS LP-8841 contains a DS-1302 RTC. RTC is connected to an IO
+memory register, which acts as an SPI master device.
+
+The device uses the standard MicroWire half-duplex transfer timing.
+Master output is set on low clock and sensed by the RTC on the rising
+edge. Master input is set by the RTC on the trailing edge and is sensed
+by the master on low clock.
+

+Description
+-----------
+
+LTC2990 is a Quad I2C Voltage, Current and Temperature Monitor.
+The chip's inputs can measure 4 voltages, or two inputs together (1+2 and 3+4)
+can be combined to measure a differential voltage, which is typically used to
+measure current through a series resistor, or a temperature.
+
+This driver currently uses the 2x differential mode only. In order to support
+other modes, the driver will need to be expanded.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+
+Sysfs attributes
+----------------
+
+The "curr*_input" measurements actually report the voltage drop across the
+input pins in microvolts. This is equivalent to the current through a 1mOhm
+sense resistor. Divide the reported value by the actual sense resistor value
+in mOhm to get the actual value.
+
+in0_input Voltage at Vcc pin in millivolt (range 2.5V to 5V)
+temp1_input Internal chip temperature in millidegrees Celcius
+curr1_input Current in mA across v1-v2 assuming a 1mOhm sense resistor.
+curr2_input Current in mA across v3-v4 assuming a 1mOhm sense resistor.

+Kernel driver nsa320_hwmon
+==========================
+
+Supported chips:
+ * Holtek HT46R065 microcontroller with onboard firmware that configures
+ it to act as a hardware monitor.
+ Prefix: 'nsa320'
+ Addresses scanned: none
+ Datasheet: Not available, driver was reverse engineered based upon the
+ Zyxel kernel source
+
+Author:
+ Adam Baker <linux@baker-net.org.uk>
+
+Description
+-----------
+
+This chip is known to be used in the Zyxel NSA320 and NSA325 NAS Units and
+also in some variants of the NSA310 but the driver has only been tested
+on the NSA320. In all of these devices it is connected to the same 3 GPIO
+lines which are used to provide chip select, clock and data lines. The
+interface behaves similarly to SPI but at much lower speeds than are normally
+used for SPI.
+
+Following each chip select pulse the chip will generate a single 32 bit word
+that contains 0x55 as a marker to indicate that data is being read correctly,
+followed by an 8 bit fan speed in 100s of RPM and a 16 bit temperature in
+tenths of a degree.
+
+
+sysfs-Interface
+---------------
+
+temp1_input - temperature input
+fan1_input - fan speed
+
+Notes
+-----
+
+The access timings used in the driver are the same as used in the Zyxel
+provided kernel. Testing has shown that if the delay between chip select and
+the first clock pulse is reduced from 100 ms to just under 10ms then the chip
+will not produce any output. If the duration of either phase of the clock
+is reduced from 100 us to less than 15 us then data pulses are likely to be
+read twice corrupting the output. The above analysis is based upon a sample
+of one unit but suggests that the Zyxel provided delay values include a
+reasonable tolerance.
+
+The driver incorporates a limit that it will not check for updated values
+faster than once a second. This is because the hardware takes a relatively long
+time to read the data from the device and when it does it reads both temp and
+fan speed. As the most likely case for two accesses in quick succession is
+to read both of these values avoiding a second read delay is desirable.

5.2. How to online memory
------------
-Even if the memory is hot-added, it is not at ready-to-use state.
-For using newly added memory, you have to "online" the memory block.
+When the memory is hot-added, the kernel decides whether or not to "online"
+it according to the policy which can be read from "auto_online_blocks" file:
-For onlining, you have to write "online" to the memory block's state file as:
+% cat /sys/devices/system/memory/auto_online_blocks
+
+The default is "offline" which means the newly added memory is not in a
+ready-to-use state and you have to "online" the newly added memory blocks
+manually. Automatic onlining can be requested by writing "online" to
+"auto_online_blocks" file:
+
+% echo online > /sys/devices/system/memory/auto_online_blocks
+
+This sets a global policy and impacts all memory blocks that will subsequently
+be hotplugged. Currently offline blocks keep their state. It is possible, under
+certain circumstances, that some memory blocks will be added but will fail to
+online. User space tools can check their "state" files
+(/sys/devices/system/memory/memoryXXX/state) and try to online them manually.
+
+If the automatic onlining wasn't requested, failed, or some memory block was
+offlined it is possible to change the individual block's state by writing to the
+"state" file:
% echo online > /sys/devices/system/memory/memoryXXX/state

+
+Capability: KVM_CAP_PPC_MULTITCE
+Architectures: ppc
+Type: vm
+
+This capability means the kernel is capable of handling hypercalls
+H_PUT_TCE_INDIRECT and H_STUFF_TCE without passing those into the user
+space. This significantly accelerates DMA operations for PPC KVM guests.
+User space should expect that its handlers for these hypercalls
+are not going to be called if user space previously registered LIOBN
+in KVM (via KVM_CREATE_SPAPR_TCE or similar calls).
+
+In order to enable H_PUT_TCE_INDIRECT and H_STUFF_TCE use in the guest,
+user space might have to advertise it for the guest. For example,
+IBM pSeries (sPAPR) guest starts using them if "hcall-multi-tce" is
+present in the "ibm,hypertas-functions" device-tree property.
+
+The hypercalls mentioned above may or may not be processed successfully
+in the kernel based fast path. If they can not be handled by the kernel,
+they will get passed on to user space. So user space still has to have
+an implementation for these despite the in kernel acceleration.

+

+KVM_CREATE_SPAPR_TCE_64 receives a 64bit window size, an IOMMU page shift and
+a bus offset of the corresponding DMA window, @size and @offset are numbers

+ This is legacy case that just jumps to the fixup code
+2) int ex_handler_fault(const struct exception_table_entry *fixup)
+ This case provides the fault number of the trap that occurred at
+ entry->insn. It is used to distinguish page faults from machine
+ check.
+3) int ex_handler_ext(const struct exception_table_entry *fixup)
+ This case is used for uaccess_err ... we need to set a flag
+ in the task structure. Before the handler functions existed this
+ case was handled by adding a large offset to the fixup to tag
+ it as special.
+More functions can easily be added.

+ * Hypervisor exception vector and handlers
+ *
+ *
+ * The KVM/ARM Hypervisor ABI is defined as follows:
+ *
+ * Entry to Hyp mode from the host kernel will happen _only_ when an HVC
+ * instruction is issued since all traps are disabled when running the host
+ * kernel as per the Hyp-mode initialization at boot time.
+ *
+ * HVC instructions cause a trap to the vector page + offset 0x14 (see hyp_hvc
+ * below) when the HVC instruction is called from SVC mode (i.e. a guest or the
+ * host kernel) and they cause a trap to the vector page + offset 0x8 when HVC
+ * instructions are called from within Hyp-mode.
+ *
+ * Hyp-ABI: Calling HYP-mode functions from host (in SVC mode):
+ * Switching to Hyp mode is done through a simple HVC #0 instruction. The
+ * exception vector code will check that the HVC comes from VMID==0.
+ * - r0 contains a pointer to a HYP function
+ * - r1, r2, and r3 contain arguments to the above function.
+ * - The HYP function will be called with its arguments in r0, r1 and r2.
+ * On HYP function return, we return directly to SVC.
+ *
+ * Note that the above is used to execute code in Hyp-mode from a host-kernel
+ * point of view, and is a different concept from performing a world-switch and
+ * executing guest code SVC mode (with a VMID != 0).

- * Entry to Hyp mode from the host kernel will happen _only_ when an HVC
- * instruction is issued since all traps are disabled when running the host
- * kernel as per the Hyp-mode initialization at boot time.
- *
- * HVC instructions cause a trap to the vector page + offset 0x14 (see hyp_hvc

- * host kernel) and they cause a trap to the vector page + offset 0x8 when HVC
- * instructions are called from within Hyp-mode.
- *
- * Hyp-ABI: Calling HYP-mode functions from host (in SVC mode):
- * Switching to Hyp mode is done through a simple HVC #0 instruction. The
- * exception vector code will check that the HVC comes from VMID==0 and if
- * so will push the necessary state (SPSR, lr_usr) on the Hyp stack.
- * - r0 contains a pointer to a HYP function
- * - r1, r2, and r3 contain arguments to the above function.
- * - The HYP function will be called with its arguments in r0, r1 and r2.
- * On HYP function return, we return directly to SVC.
- *
- * Note that the above is used to execute code in Hyp-mode from a host-kernel
- * point of view, and is a different concept from performing a world-switch and
- * executing guest code SVC mode (with a VMID != 0).

+ *
+ * This driver acts as a paravirtual front-end for PCI Express root buses.
+ * When a PCI Express function (either an entire device or an SR-IOV
+ * Virtual Function) is being passed through to the VM, this driver exposes
+ * a new bus to the guest VM. This is modeled as a root PCI bus because
+ * no bridges are being exposed to the VM. In fact, with a "Generation 2"
+ * VM within Hyper-V, there may seem to be no PCI bus at all in the VM
+ * until a device as been exposed using this driver.
+ *
+ * Each root PCI bus has its own PCI domain, which is called "Segment" in
+ * the PCI Firmware Specifications. Thus while each device passed through
+ * to the VM using this front-end will appear at "device 0", the domain will
+ * be unique. Typically, each bus will have one PCI function on it, though
+ * this driver does support more than one.
+ *
+ * In order to map the interrupts from the device through to the guest VM,
+ * this driver also implements an IRQ Domain, which handles interrupts (either
+ * MSI or MSI-X) associated with the functions on the bus. As interrupts are
+ * set up, torn down, or reaffined, this driver communicates with the
+ * underlying hypervisor to adjust the mappings in the I/O MMU so that each
+ * interrupt will be delivered to the correct virtual processor at the right
+ * vector. This driver does not support level-triggered (line-based)
+ * interrupts, and will report that the Interrupt Line register in the
+ * function's configuration space is zero.
+ *
+ * The rest of this driver mostly maps PCI concepts onto underlying Hyper-V
+ * facilities. For instance, the configuration space of a function exposed
+ * by Hyper-V is mapped into a single page of memory space, and the
+ * read and write handlers for config space must be aware of this mechanism.
+ * Similarly, device setup and teardown involves messages sent to and from
+ * the PCI back-end driver in Hyper-V.

+ * dwc3_gadget_start_config - Configure EP resources
+ * @dwc: pointer to our controller context structure
+ * @dep: endpoint that is being enabled
+ *
+ * The assignment of transfer resources cannot perfectly follow the
+ * data book due to the fact that the controller driver does not have
+ * all knowledge of the configuration in advance. It is given this
+ * information piecemeal by the composite gadget framework after every
+ * SET_CONFIGURATION and SET_INTERFACE. Trying to follow the databook
+ * programming model in this scenario can cause errors. For two
+ * reasons:
+ *
+ * 1) The databook says to do DEPSTARTCFG for every SET_CONFIGURATION
+ * and SET_INTERFACE (8.1.5). This is incorrect in the scenario of
+ * multiple interfaces.
+ *
+ * 2) The databook does not mention doing more DEPXFERCFG for new
+ * endpoint on alt setting (8.1.6).
+ *
+ * The following simplified method is used instead:
+ *
+ * All hardware endpoints can be assigned a transfer resource and this
+ * setting will stay persistent until either a core reset or
+ * hibernation. So whenever we do a DEPSTARTCFG(0) we can go ahead and
+ * do DEPXFERCFG for every hardware endpoint as well. We are
+ * guaranteed that there are as many transfer resources as endpoints.
+ *
+ * This function is called for each endpoint when it is being enabled
+ * but is triggered only when called for EP0-out, which always happens
+ * first, and which should only happen in one of the above conditions.

Memory could be hotplugged in following steps:
- 1) dom0: xl mem-max <domU> <maxmem>
+ 1) target domain: ensure that memory auto online policy is in
+ effect by checking /sys/devices/system/memory/auto_online_blocks
+ file (should be 'online').
+
+ 2) control domain: xl mem-max <target-domain> <maxmem>
where <maxmem> is >= requested memory size,
- 2) dom0: xl mem-set <domU> <memory>
+ 3) control domain: xl mem-set <target-domain> <memory>
where <memory> is requested memory size; alternatively memory
could be added by writing proper value to
/sys/devices/system/xen_memory/xen_memory0/target or
- /sys/devices/system/xen_memory/xen_memory0/target_kb on dumU,
+ /sys/devices/system/xen_memory/xen_memory0/target_kb on the
+ target domain.
- 3) domU: for i in /sys/devices/system/memory/memory*/state; do \
- [ "`cat "$i"`" = offline ] && echo online > "$i"; done
+ Alternatively, if memory auto onlining was not requested at step 1
+ the newly added memory can be manually onlined in the target domain
+ by doing the following:
- Memory could be onlined automatically on domU by adding following line to udev rules:
+ for i in /sys/devices/system/memory/memory*/state; do \
+ [ "`cat "$i"`" = offline ] && echo online > "$i"; done
+
+ or by adding the following line to udev rules:
SUBSYSTEM=="memory", ACTION=="add", RUN+="/bin/sh -c '[ -f /sys$devpath/state ] && echo online > /sys$devpath/state'"
- In that case step 3 should be omitted.

JFFS2 LOCKING DOCUMENTATION

-(BKL), which was always helpfully obtained for it by Linux 2.4 VFS

This document attempts to describe the existing locking rules for
JFFS2. It is not expected to remain perfectly up to date, but ought to
be fairly close.

+Variables
+~~~~~~~~~
+
+colors.*::
+ The variables for customizing the colors used in the output for the
+ 'report', 'top' and 'annotate' in the TUI. They should specify the
+ foreground and background colors, separated by a comma, for example:
+
+ medium = green, lightgray
+
+ If you want to use the color configured for you terminal, just leave it
+ as 'default', for example:
+
+ medium = default, lightgray
+
+ Available colors:
+ red, yellow, green, cyan, gray, black, blue,
+ white, default, magenta, lightgray
+
+ colors.top::
+ 'top' means a overhead percentage which is more than 5%.
+ And values of this variable specify percentage colors.
+ Basic key values are foreground-color 'red' and
+ background-color 'default'.
+ colors.medium::
+ 'medium' means a overhead percentage which has more than 0.5%.
+ Default values are 'green' and 'default'.
+ colors.normal::
+ 'normal' means the rest of overhead percentages
+ except 'top', 'medium', 'selected'.
+ Default values are 'lightgray' and 'default'.
+ colors.selected::
+ This selects the colors for the current entry in a list of entries
+ from sub-commands (top, report, annotate).
+ Default values are 'black' and 'lightgray'.
+ colors.jump_arrows::
+ Colors for jump arrows on assembly code listings
+ such as 'jns', 'jmp', 'jane', etc.
+ Default values are 'blue', 'default'.
+ colors.addr::
+ This selects colors for addresses from 'annotate'.
+ Default values are 'magenta', 'default'.
+ colors.root::
+ Colors for headers in the output of a sub-commands (top, report).
+ Default values are 'white', 'blue'.
+
+tui.*, gtk.*::
+ Subcommands that can be configured here are 'top', 'report' and 'annotate'.
+ These values are booleans, for example:
+
+ [tui]
+ top = true
+
+ will make the TUI be the default for the 'top' subcommand. Those will be
+ available if the required libs were detected at tool build time.
+
+buildid.*::
+ buildid.dir::
+ Each executable and shared library in modern distributions comes with a
+ content based identifier that, if available, will be inserted in a
+ 'perf.data' file header to, at analysis time find what is needed to do

+
+ The recording tools also stores a hard link or copy in a per-user
+ directory, $HOME/.debug/, of binaries, shared libraries, /proc/kallsyms
+ and /proc/kcore files to be used at analysis time.
+
+ The buildid.dir variable can be used to either change this directory
+ cache location, or to disable it altogether. If you want to disable it,
+ set buildid.dir to /dev/null. The default is $HOME/.debug
+
+annotate.*::
+ These options work only for TUI.
+ These are in control of addresses, jump function, source code
+ in lines of assembly code from a specific program.
+
+ annotate.hide_src_code::
+ If a program which is analyzed has source code,
+ this option lets 'annotate' print a list of assembly code with the source code.
+ For example, let's see a part of a program. There're four lines.
+ If this option is 'true', they can be printed
+ without source code from a program as below.
+
+ │ push %rbp
+ │ mov %rsp,%rbp
+ │ sub $0x10,%rsp
+ │ mov (%rdi),%rdx
+
+ But if this option is 'false', source code of the part
+ can be also printed as below. Default is 'false'.
+
+ │ struct rb_node *rb_next(const struct rb_node *node)
+ │ {
+ │ push %rbp
+ │ mov %rsp,%rbp
+ │ sub $0x10,%rsp
+ │ struct rb_node *parent;
+ │
+ │ if (RB_EMPTY_NODE(node))
+ │ mov (%rdi),%rdx
+ │ return n;
+
+ annotate.use_offset::
+ Basing on a first address of a loaded function, offset can be used.
+ Instead of using original addresses of assembly code,
+ addresses subtracted from a base address can be printed.
+ Let's illustrate an example.
+ If a base address is 0XFFFFFFFF81624d50 as below,
+
+ ffffffff81624d50 <load0>
+
+ an address on assembly code has a specific absolute address as below
+
+ ffffffff816250b8:│ mov 0x8(%r14),%rdi
+
+ but if use_offset is 'true', an address subtracted from a base address is printed.
+ Default is true. This option is only applied to TUI.
+
+ 368:│ mov 0x8(%r14),%rdi
+
+ annotate.jump_arrows::
+ There can be jump instruction among assembly code.
+ Depending on a boolean value of jump_arrows,
+ arrows can be printed or not which represent
+ where do the instruction jump into as below.
+
+ │ ┌──jmp 1333
+ │ │ xchg %ax,%ax
+ │1330:│ mov %r15,%r10
+ │1333:└─→cmp %r15,%r14
+
+ If jump_arrow is 'false', the arrows isn't printed as below.
+ Default is 'false'.
+
+ │ ↓ jmp 1333
+ │ xchg %ax,%ax
+ │1330: mov %r15,%r10
+ │1333: cmp %r15,%r14
+
+ annotate.show_linenr::
+ When showing source code if this option is 'true',
+ line numbers are printed as below.
+
+ │1628 if (type & PERF_SAMPLE_IDENTIFIER) {
+ │ ↓ jne 508
+ │1628 data->id = *array;
+ │1629 array++;
+ │1630 }
+
+ However if this option is 'false', they aren't printed as below.
+ Default is 'false'.
+
+ │ if (type & PERF_SAMPLE_IDENTIFIER) {
+ │ ↓ jne 508
+ │ data->id = *array;
+ │ array++;
+ │ }
+
+ annotate.show_nr_jumps::
+ Let's see a part of assembly code.
+
+ │1382: movb $0x1,-0x270(%rbp)
+
+ If use this, the number of branches jumping to that address can be printed as below.
+ Default is 'false'.
+
+ │1 1382: movb $0x1,-0x270(%rbp)
+
+ annotate.show_total_period::
+ To compare two records on an instruction base, with this option
+ provided, display total number of samples that belong to a line
+ in assembly code. If this option is 'true', total periods are printed
+ instead of percent values as below.
+
+ 302 │ mov %eax,%eax
+
+ But if this option is 'false', percent values for overhead are printed i.e.
+ Default is 'false'.
+
+ 99.93 │ mov %eax,%eax
+
+hist.*::
+ hist.percentage::
+ This option control the way to calculate overhead of filtered entries -
+ that means the value of this option is effective only if there's a
+ filter (by comm, dso or symbol name). Suppose a following example:
+
+ Overhead Symbols
+ ........ .......
+ 33.33% foo
+ 33.33% bar
+ 33.33% baz
+
+ This is an original overhead and we'll filter out the first 'foo'
+ entry. The value of 'relative' would increase the overhead of 'bar'
+ and 'baz' to 50.00% for each, while 'absolute' would show their
+ current overhead (33.33%).
+
+ui.*::
+ ui.show-headers::
+ This option controls display of column headers (like 'Overhead' and 'Symbol')
+ in 'report' and 'top'. If this option is false, they are hidden.
+ This option is only applied to TUI.
+
+call-graph.*::
+ When sub-commands 'top' and 'report' work with -g/—-children
+ there're options in control of call-graph.
+
+ call-graph.record-mode::
+ The record-mode can be 'fp' (frame pointer), 'dwarf' and 'lbr'.
+ The value of 'dwarf' is effective only if perf detect needed library
+ (libunwind or a recent version of libdw).
+ 'lbr' only work for cpus that support it.
+
+ call-graph.dump-size::
+ The size of stack to dump in order to do post-unwinding. Default is 8192 (byte).
+ When using dwarf into record-mode, the default size will be used if omitted.
+
+ call-graph.print-type::
+ The print-types can be graph (graph absolute), fractal (graph relative),
+ flat and folded. This option controls a way to show overhead for each callchain
+ entry. Suppose a following example.
+
+ Overhead Symbols
+ ........ .......
+ 40.00% foo
+ |
+ ---foo
+ |
+ |--50.00%--bar
+ | main
+ |
+ --50.00%--baz
+ main
+
+ This output is a 'fractal' format. The 'foo' came from 'bar' and 'baz' exactly
+ half and half so 'fractal' shows 50.00% for each
+ (meaning that it assumes 100% total overhead of 'foo').
+
+ The 'graph' uses absolute overhead value of 'foo' as total so each of
+ 'bar' and 'baz' callchain will have 20.00% of overhead.
+ If 'flat' is used, single column and linear exposure of call chains.
+ 'folded' mean call chains are displayed in a line, separated by semicolons.
+
+ call-graph.order::
+ This option controls print order of callchains. The default is
+ 'callee' which means callee is printed at top and then followed by its
+ caller and so on. The 'caller' prints it in reverse order.
+
+ If this option is not set and report.children or top.children is
+ set to true (or the equivalent command line option is given),
+ the default value of this option is changed to 'caller' for the
+ execution of 'perf report' or 'perf top'. Other commands will
+ still default to 'callee'.
+
+ call-graph.sort-key::
+ The callchains are merged if they contain same information.
+ The sort-key option determines a way to compare the callchains.
+ A value of 'sort-key' can be 'function' or 'address'.
+ The default is 'function'.
+
+ call-graph.threshold::
+ When there're many callchains it'd print tons of lines. So perf omits
+ small callchains under a certain overhead (threshold) and this option
+ control the threshold. Default is 0.5 (%). The overhead is calculated
+ by value depends on call-graph.print-type.
+
+ call-graph.print-limit::
+ This is a maximum number of lines of callchain printed for a single
+ histogram entry. Default is 0 which means no limitation.
+
+report.*::
+ report.percent-limit::
+ This one is mostly the same as call-graph.threshold but works for
+ histogram entries. Entries having an overhead lower than this
+ percentage will not be printed. Default is '0'. If percent-limit
+ is '10', only entries which have more than 10% of overhead will be
+ printed.
+
+ report.queue-size::
+ This option sets up the maximum allocation size of the internal
+ event queue for ordering events. Default is 0, meaning no limit.
+
+ report.children::
+ 'Children' means functions called from another function.
+ If this option is true, 'perf report' cumulates callchains of children
+ and show (accumulated) total overhead as well as 'Self' overhead.
+ Please refer to the 'perf report' manual. The default is 'true'.
+
+ report.group::
+ This option is to show event group information together.
+ Example output with this turned on, notice that there is one column
+ per event in the group, ref-cycles and cycles:
+
+ # group: {ref-cycles,cycles}
+ # ========
+ #
+ # Samples: 7K of event 'anon group { ref-cycles, cycles }'
+ # Event count (approx.): 6876107743
+ #
+ # Overhead Command Shared Object Symbol
+ # ................ ....... ................. ...................
+ #
+ 99.84% 99.76% noploop noploop [.] main
+ 0.07% 0.00% noploop ld-2.15.so [.] strcmp
+ 0.03% 0.00% noploop [kernel.kallsyms] [k] timerqueue_del
+
+top.*::
+ top.children::
+ Same as 'report.children'. So if it is enabled, the output of 'top'
+ command will have 'Children' overhead column as well as 'Self' overhead
+ column by default.
+ The default is 'true'.
+
+man.*::
+ man.viewer::
+ This option can assign a tool to view manual pages when 'help'
+ subcommand was invoked. Supported tools are 'man', 'woman'
+ (with emacs client) and 'konqueror'. Default is 'man'.
+
+ New man viewer tool can be also added using 'man.<tool>.cmd'
+ or use different path using 'man.<tool>.path' config option.
+
+pager.*::
+ pager.<subcommand>::
+ When the subcommand is run on stdio, determine whether it uses
+ pager or not based on this value. Default is 'unspecified'.
+
+kmem.*::
+ kmem.default::
+ This option decides which allocator is to be analyzed if neither
+ '--slab' nor '--page' option is used. Default is 'slab'.
+
+record.*::
+ record.build-id::
+ This option can be 'cache', 'no-cache' or 'skip'.
+ 'cache' is to post-process data and save/update the binaries into
+ the build-id cache (in ~/.debug). This is the default.
+ But if this option is 'no-cache', it will not update the build-id cache.
+ 'skip' skips post-processing and does not update the cache.
