This is a static node, once initialized this
is not expected to change during runtime. "dfp"
refers to "downstream facing port" i.e. port can
only act as host. "ufp" refers to "upstream
facing port" i.e. port can only act as device.
"dfp ufp" refers to "dual role port" i.e. the port
can either be a host port or a device port.

Description:
The mode node refers to the current mode in which the
port is operating. "dfp" for host ports. "ufp" for device
ports and "none" when cable is not connected.
On devices where the USB mode is software-controllable,
userspace can change the mode by writing "dfp" or "ufp".
On devices where the USB mode is fixed in hardware,
this attribute is read-only.

@ -587,6 +587,64 @@ This governor exposes the following tunables:
It effectively causes the frequency to go down ``sampling_down_factor``
times slower than it ramps up.
``interactive``
----------------
The CPUfreq governor `interactive` is designed for latency-sensitive,
interactive workloads. This governor sets the CPU speed depending on
usage, similar to `ondemand` and `conservative` governors, but with a
different set of configurable behaviors.
The tunable values for this governor are:
``above_hispeed_delay``
When speed is at or above hispeed_freq, wait for
this long before raising speed in response to continued high load.
The format is a single delay value, optionally followed by pairs of
CPU speeds and the delay to use at or above those speeds. Colons can
be used between the speeds and associated delays for readability. For
example:
80000 1300000:200000 1500000:40000
uses delay 80000 uS until CPU speed 1.3 GHz, at which speed delay
200000 uS is used until speed 1.5 GHz, at which speed (and above)
delay 40000 uS is used. If speeds are specified these must appear in
ascending order. Default is 20000 uS.
``boost``
If non-zero, immediately boost speed of all CPUs to at least
hispeed_freq until zero is written to this attribute. If zero, allow
CPU speeds to drop below hispeed_freq according to load as usual.
Default is zero.
``boostpulse``
On each write, immediately boost speed of all CPUs to
hispeed_freq for at least the period of time specified by
boostpulse_duration, after which speeds are allowed to drop below
hispeed_freq according to load as usual. Its a write-only file.
``boostpulse_duration``
Length of time to hold CPU speed at hispeed_freq
on a write to boostpulse, before allowing speed to drop according to
load as usual. Default is 80000 uS.
``go_hispeed_load``
The CPU load at which to ramp to hispeed_freq.
Default is 99%.
``hispeed_freq``
An intermediate "high speed" at which to initially ramp
when CPU load hits the value specified in go_hispeed_load. If load
stays high for the amount of time specified in above_hispeed_delay,
then speed may be bumped higher. Default is the maximum speed allowed
by the policy at governor initialization time.
``io_is_busy``
If set, the governor accounts IO time as CPU busy time.
``min_sample_time``
The minimum amount of time to spend at the current

Android (www.android.com) is an open source operating system for mobile devices.
This document describes configurations needed to run the Android framework on
top of the Linux kernel.
To see a working defconfig look at msm_defconfig or goldfish_defconfig
which can be found at http://android.git.kernel.org in kernel/common.git
and kernel/msm.git
1.1 Required enabled config options
-----------------------------------
After building a standard defconfig, ensure that these options are enabled in
your .config or defconfig if they are not already. Based off the msm_defconfig.
You should keep the rest of the default options enabled in the defconfig
unless you know what you are doing.

confronted with a slow MMC.
Enables max_read_speed, max_write_speed and cache_size attributes and module
default parameters to control the write or read maximum KB/second speed
behaviors.
NB: There is room for improving the algorithm for aspects tied directly to
eMMC specific behavior. For instance, wear leveling and stalls from an
exhausted erase pool. We would expect that if there was a need to provide
similar speed simulation controls to other types of block devices, aspects of
their behavior are modelled separately (e.g. head seek times, heat assist,
shingling and rotational latency).
/sys/block/mmcblk0/max_read_speed:
Number of KB/second reads allowed to the block device. Used to test and
simulate the behavior of the system when confronted with a slow reading MMC.
Set to 0 or "off" to place no speed limit.
/sys/block/mmcblk0/max_write_speed:
Number of KB/second writes allowed to the block device. Used to test and
simulate the behavior of the system when confronted with a slow writing MMC.
Set to 0 or "off" to place no speed limit.
/sys/block/mmcblk0/cache_size:
Number of MB of high speed memory or high speed SLC cache expected on the
eMMC device being simulated. Used to help simulate the write-back behavior
more accurately. The assumption is the cache has no delay, but draws down
in the background to the MLC/TLC primary store at the max_write_speed rate.
Any write speed delays will show up when the cache is full, or when an I/O
request to flush is issued.

Boot time creation of mapped devices
===================================
It is possible to configure a device mapper device to act as the root
device for your system in two ways.
The first is to build an initial ramdisk which boots to a minimal
userspace which configures the device, then pivot_root(8) in to it.
For simple device mapper configurations, it is possible to boot directly
using the following kernel command line:
dm="<name> <uuid> <ro>,table line 1,...,table line n"
name = the name to associate with the device
after boot, udev, if used, will use that name to label
the device node.
uuid = may be 'none' or the UUID desired for the device.
ro = may be "ro" or "rw". If "ro", the device and device table will be
marked read-only.
Each table line may be as normal when using the dmsetup tool except for
two variations:
1. Any use of commas will be interpreted as a newline
2. Quotation marks cannot be escaped and cannot be used without
terminating the dm= argument.
Unless renamed by udev, the device node created will be dm-0 as the
first minor number for the device-mapper is used during early creation.
Example
=======
- Booting to a linear array made up of user-mode linux block devices:
dm="lroot none 0, 0 4096 linear 98:16 0, 4096 4096 linear 98:32 0" \
root=/dev/dm-0
Will boot to a rw dm-linear target of 8192 sectors split across two
block devices identified by their major:minor numbers. After boot, udev
will rename this target to /dev/mapper/lroot (depending on the rules).
No uuid was assigned.

Motivation:
In complicated DMA pipelines such as graphics (multimedia, camera, gpu, display)
a consumer of a buffer needs to know when the producer has finished producing
it. Likewise the producer needs to know when the consumer is finished with the
buffer so it can reuse it. A particular buffer may be consumed by multiple
consumers which will retain the buffer for different amounts of time. In
addition, a consumer may consume multiple buffers atomically.
The sync framework adds an API which allows synchronization between the
producers and consumers in a generic way while also allowing platforms which
have shared hardware synchronization primitives to exploit them.
Goals:
* provide a generic API for expressing synchronization dependencies
* allow drivers to exploit hardware synchronization between hardware
blocks
* provide a userspace API that allows a compositor to manage
dependencies.
* provide rich telemetry data to allow debugging slowdowns and stalls of
the graphics pipeline.
Objects:
* sync_timeline
* sync_pt
* sync_fence
sync_timeline:
A sync_timeline is an abstract monotonically increasing counter. In general,
each driver/hardware block context will have one of these. They can be backed
by the appropriate hardware or rely on the generic sw_sync implementation.
Timelines are only ever created through their specific implementations
(i.e. sw_sync.)
sync_pt:
A sync_pt is an abstract value which marks a point on a sync_timeline. Sync_pts
have a single timeline parent. They have 3 states: active, signaled, and error.
They start in active state and transition, once, to either signaled (when the
timeline counter advances beyond the sync_pt’s value) or error state.
sync_fence:
Sync_fences are the primary primitives used by drivers to coordinate
synchronization of their buffers. They are a collection of sync_pts which may
or may not have the same timeline parent. A sync_pt can only exist in one fence
and the fence's list of sync_pts is immutable once created. Fences can be
waited on synchronously or asynchronously. Two fences can also be merged to
create a third fence containing a copy of the two fences’ sync_pts. Fences are
backed by file descriptors to allow userspace to coordinate the display pipeline
dependencies.
Use:
A driver implementing sync support should have a work submission function which:
* takes a fence argument specifying when to begin work
* asynchronously queues that work to kick off when the fence is signaled
* returns a fence to indicate when its work will be done.
* signals the returned fence once the work is completed.
Consider an imaginary display driver that has the following API:
/*
* assumes buf is ready to be displayed.
* blocks until the buffer is on screen.
*/
void display_buffer(struct dma_buf *buf);
The new API will become:
/*
* will display buf when fence is signaled.
* returns immediately with a fence that will signal when buf
* is no longer displayed.
*/
struct sync_fence* display_buffer(struct dma_buf *buf,
struct sync_fence *fence);
