+DMA_ATTR_NO_KERNEL_MAPPING
+--------------------------
+
+DMA_ATTR_NO_KERNEL_MAPPING lets the platform to avoid creating a kernel
+virtual mapping for the allocated buffer. On some architectures creating
+such mapping is non-trivial task and consumes very limited resources
+(like kernel virtual address space or dma consistent address space).
+Buffers allocated with this attribute can be only passed to user space
+by calling dma_mmap_attrs(). By using this API, you are guaranteeing
+that you won't dereference the pointer returned by dma_alloc_attr(). You
+can threat it as a cookie that must be passed to dma_mmap_attrs() and
+dma_free_attrs(). Make sure that both of these also get this attribute
+set on each call.

+Since it is optional for platforms to implement
+DMA_ATTR_NO_KERNEL_MAPPING, those that do not will simply ignore the

+DMA_ATTR_STRONGLY_ORDERED allocates memory with a very restrictive type
+of mapping (no unaligned accesses, no re-ordering, no write merging, no
+buffering, no pre-fetching). This has severe performance penalties and
+should not be used for general purpose DMA allocations. It should only
+be used if one of the restrictions on strongly ordered memory is required.

The ROW IO scheduler was developed with the mobile devices needs in
mind. In mobile devices we favor user experience upon everything else,
thus we want to give READ IO requests as much priority as possible.
-The main idea of the ROW scheduling policy is:
-If there are READ requests in pipe - dispatch them but don't starve
-the WRITE requests too much.
+The main idea of the ROW scheduling policy is just that:
+- If there are READ requests in pipe - dispatch them, while write
+starvation is considered.
Software description
====================
+The elevator defines a registering mechanism for different IO scheduler
+to implement. This makes implementing a new algorithm quite straight
+forward and requires almost no changes to block/elevator framework. A
+new IO scheduler just has to implement a set of callback functions
+defined by the elevator.
+These callbacks cover all the required IO operations such as
+adding/removing request to/from the scheduler, merging two requests,
+dispatching a request etc.
+
+Design
+======
+
The requests are kept in queues according to their priority. The
dispatching of requests is done in a Round Robin manner with a
different slice for each queue. The dispatch quantum for a specific
-queue is defined according to the queues priority. READ queues are
+queue is set according to the queues priority. READ queues are
given bigger dispatch quantum than the WRITE queues, within a dispatch
cycle.

- Regular priority WRITE queue
- Low priority READ queue
+The marking of request as high/low priority will be done by the
+application adding the request and not the scheduler. See TODO section.
+If the request is not marked in any way (high/low) the scheduler
+assigns it to one of the regular priority queues:
+read/write/sync write.

If in a certain dispatch cycle one of the queues was empty and didn't

arrives for queue X that was un-served in the previous cycle, if X's
priority is higher than Y's, queue X will be preempted in the favor of
-queue Y. This won't mean that cycle is restarted. The "dispatched"
-counter of queue X will remain unchanged. Once queue Y uses up it's quantum
-(or there will be no more requests left on it) we'll switch back to queue X
-and allow it to finish it's quantum.
+queue Y.
-For READ requests queues we allow idling in within a dispatch quantum in
-order to give the application a chance to insert more requests. Idling

-queue is empty. The idling is enabled if we identify the application is

+certain queue even if the queue is empty. The idling is enabled if
+the ROW IO scheduler identifies the application is inserting requests
+in a high frequency.
+Not all queues can idle. ROW scheduler exposes an enablement struct
+for idling.
+For idling on READ queues, the ROW IO scheduler uses timer mechanism.
+When the timer expires we schedule a delayed work that will signal the
+device driver to fetch another request for dispatch.
-For idling on READ queues we use timer mechanism. When the timer expires,

-it a bit more "user-needs oriented", by allowing the application to
-hint on the urgency of its requests. For example: even among the READ
-requests several requests may be more urgent for completion then others.
-The former will go to the High priority READ queue, that is given the
-bigger dispatch quantum than any other queue.

-ROW scheduler will support special services for block devices that

+ROW scheduler will support additional services for block devices that

In addition it will support rescheduling of requests that were
-interrupted. For example, if the device issues a long write request and
-a sudden high priority read interrupt pops in, the scheduler will
-inform the device about the urgent request, so the device can stop the
-current write request and serve the high priority read request. In such

-When deciding on the next request to dispatch they choose the closest
-request to the current disk head position (from handling last
-dispatched request). This is done in order to reduce the disk head
-movement to a minimum.
-We feel that this functionality isn't really needed in mobile devices.
-Usually applications that write/read large chunks of data insert the
-requests in already sorted LBA order. Thus dealing with sort trees adds
-unnecessary complexity.

-We're planing to try this enhancement in the future to check if the
-performance is influenced by it.

Background Processing
---------------------
-When demux receives notifications from underlying HW drivers about new
-data, it schedules work to a single-threaded workqueue to process the
-notification.
+Demux allocates a kernel thread for each live-input to process
+the TS packets notified from the HW for specific input. There
+are two such inputs (TSIF0 and TSIF1), both can be processed in
+parallel by two seperate threads.
The processing is the action of demuxing of the new data; it may sleep
as it locks against the demux data-structure that may be accessed by
user-space in the meanwhile.
-A single threaded workqueue exists for each live input (TSIF0 or TSIF1)
-to process the inputs in parallel.

Dependencies
------------
The demux driver depends on the following kernel drivers and subsystems:

+Subsystem Trace Points: msm_low_power
+
+The msm_low_power tracing system captures the events during the entry
+and exit of various low power modes like power collapse, standalone
+power collapse, retention and wfi. The tracing system adds the following
+events to capture the state of the low power mode.
+
+1) msm_pm_enter
+===================
+msm_pm_enter: cpu: %u latency: %uus sleep: %uus
+msm_pm_enter_pc: cpu: %u latency: %uus sleep: %uus wake_up: %u
+msm_pm_enter_ret: cpu: %u latency: %uus sleep: %uus wake_up: %u
+msm_pm_enter_spc: cpu: %u latency: %uus sleep: %uus wake_up: %u
+msm_pm_enter_wfi: cpu: %u latency: %uus sleep: %uus wake_up: %u
+
+The event captures various parameters during the entry into low power
+modes.
+
+The 'cpu' parameter represents the cpu on which the low power mode is
+chosen.
+
+The 'latency_us' parameter represents the system latency at the time of
+choosing the low power mode.
+
+The 'sleep_us' parameter tells the maximum amount of time the kernel can
+sleep in this low power mode.
+
+The 'wake_up' parameter tells if there was any immediate wakeup required
+before entering low power mode.
+
+2) msm_pm_exit
+=================
+msm_pm_exit: cpu:%u success:%d
+msm_pm_exit_pc: cpu:%u success:%d
+msm_pm_exit_ret: cpu:%u success:%d
+msm_pm_exit_spc: cpu:%u success:%d
+msm_pm_exit_wfi: cpu:%u success:%d
+
+The event captures parameters during the exit of the low power modes.
+
+The 'cpu' parameter represents the cpu on which the low power mode is chosen.
+
+The 'success' parameter shows the state of power collapse/standalone power
+collapse. It will be set if power collapse/standalone power collapse were
+successful. For the rest of the low power modes it is set to one.
+
+3) lpm_resources
+=================
+lpm_resources: name:%s sleep_value:%d
+
+This event captures parameters for each of the lpm resources.
+
+The 'name' parameter represents the name of the lpm resource and it can hold
+l2, pxo, vdd mem, vdd dig depending on the resource chosen during power
+collapse.
+
+The 'sleep_value' parameter corresponds to the sleep value set for the resource.

+Subsystem Trace Points: rpm_smd
+
+The rpm-smd tracing system captures the events related to sending/receiving
+messages to/from RPM hardware. The tracing system adds the following events to
+capture the transactions with the RPM driver.
+
+1) RPM send message
+===================
+rpm_send_message: ctx:%s set:%s rsc_type:0%x(%s),rsc_id:i0x%x, id:%u
+
+The event captures the parameters of the message that was sent to the RPM.
+
+The 'ctx' parameters takes one of the following string constants to indicate
+if the request was made in atomic/non-atomic context.
+ . "sleep" - non-atomic context
+ . "noslp" - atomic context
+
+The 'set' parameter takes one of the following string values to indicate if
+the message affects active or sleep set value of the resource
+ . "act" - active set configuraion
+ . "slp" - sleep set configuration
+
+The 'rsc_type' and 'rsc_id' identify the resource whose parametes is being
+modified. The 4 bytes string equivalent of the resource type is also displayed
+for easier identification of resources.
+
+The 'id' parameter is the id that RPM uses to acknowledge the receipt of the
+message in its ACK message
+
+
+2) RPM ack message
+=================
+rpm_ack_recd: ctx:%s id:%u
+
+The event captures the acknowledgement messages received from the RPM after
+successfully send a message request.
+
+The 'ctx' parameter has the same string constants referred to the "RPM Send
+Message"
+
+The 'id' parameter is the id that RPM uses to acknowledge the receipt of the
