+Introduction
+============
+
+The MSM ADSPRPC driver implements an IPC (Inter-Processor Communication)
+mechanism that allows for clients to transparently make remote method
+invocations across processor boundaries.
+
+The below diagram depicts invocation of a single method where the client
+and objects reside on different processors. An object could expose
+multiple methods which can be grouped together and referred to as an
+interface.
+
+: ,--------, ,------, ,-----------, ,------, ,--------,
+: | | method | | | | | | method | |
+: | Client |------->| Stub |->| Transport |->| Skel |------->| Object |
+: | | | | | | | | | |
+: `--------` `------` `-----------` `------` `--------`
+
+Client: Linux user mode process that initiates the remote invocation
+Stub: Auto generated code linked in with the user mode process that
+ takes care of marshaling parameters
+Transport: Involved in carrying an invocation from a client to an
+ object. This involves two portions: 1) MSM ADSPRPC Linux
+ kernel driver that receives the remote invocation, queues
+ them up and then waits for the response after signaling the
+ remote side. 2) Service running on the remote side that
+ dequeues the messages from the queue and dispatches them for
+ processing.
+Skel: Auto generated code that takes care of un-marshaling
+ parameters
+Object: Method implementation
+
+Hardware description
+====================
+
+The driver interfaces with the components in the DSP subsystem and does
+not drive or manage any hardware resources.
+
+Software description
+====================
+
+The MSM ADSPRPC driver uses SMD (Shared Memory Driver) to send and
+receive messages with the remote processor. The SMD channel used for
+communication is opened during initialization of the driver and is
+closed when the driver module is unloaded. The driver does not expose
+HLOS memory to the remote processor but rather communication of
+invocation parameters happen over ION allocated buffers.
+
+The driver receives remote call invocations via an ioctl call. When a
+remote call invocation is received, the driver does the following:
+- Retrieves the invocation parameters
+- Copies input buffers in HLOS memory to ION allocated buffers
+- Allocates ION buffers for output buffers in HLOS memory as required
+- Scatter-gathers list of pages for ION allocated input and output
+ buffers
+- Coalesces information about the contiguous page buffers
+- Builds up a message with the received information
+- Sends the message to a remote processor through an SMD channel
+- Waits for a response from the remote processor through the SMD channel
+- Reads the message available from the shared memory SMD channel
+- Copies back from ION buffers to HLOS memory for output buffers
+- Returns the response of the remote invocation
+
+Design
+======
+
+The design goals of this transport mechanism are:
+- Fast and efficient ways to transfer huge buffers across
+ inter-processor boundaries
+- Zero copy of ION allocated buffers passed during invocations
+
+To achieve the zero copy approach of ION allocated user space buffers,
+the driver scatter-gathers the list of pages of the buffers being passed
+in. This information is then sent over to the remote processor for it
+to map into its address space.
+
+The invocation requests sent over the SMD channel carry context
+information as to whom the request is originating from. The responses
+received over the SMD channel have context information in the message
+which is then used to wake the thread waiting for a response.
+
+If the remote processor goes down and gets restarted, the SMD channel
+is re-initialized when the remote processor comes back up. An
+error code would be returned to the client for all invocations that
+happen before the SMD channel could get completely re-initialized.

+
+SMP/multi-core
+==============
+
+The driver uses semaphores to wake up clients waiting for a remote
+invocation response.
+
+Security
+========
+
+Use of the zero copy approach results in a page-size granularity of
+all buffers being passed to the remote processor. The objects that will
+be manipulating these buffers on the remote processor will be signed
+and trusted entities, thereby alleviating any fear of intentional
+scribbling of these buffers.
+
+Performance
+===========
+
+In order to minimize latencies across remote invocations:
+- messages exchanged between the remote processors are kept short
+- zero copy approach for ION allocated user space buffers
+
+Interface
+=========
+
+The driver exposes a user space interface through /dev/adsprpc-smd and
+the user space clients send commands to the driver by using the
+following ioctl command:
+
+- FASTRPC_IOCTL_INVOKE: Parameters passed in includes the buffers and
+ data related to remote invocation.
+
+ /*
+ * Information about the input/output buffer or an handle to the
+ * object being passed in the remote invocation

+Introduction
+============
+
+The ROW scheduling algorithm will be used in mobile devices as default
+block layer IO scheduling algorithm. ROW stands for "READ Over WRITE"
+which is the main requests dispatch policy of this algorithm.
+
+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.
+
+Software description
+====================
+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
+given bigger dispatch quantum than the WRITE queues, within a dispatch
+cycle.
+
+At the moment there are 6 types of queues the requests are
+distributed to:
+- High priority READ queue
+- High priority Synchronous WRITE queue
+- Regular priority READ queue
+- Regular priority Synchronous WRITE queue
+- Regular priority WRITE queue
+- Low priority READ queue
+
+If in a certain dispatch cycle one of the queues was empty and didn't
+use its quantum that queue will be marked as "un-served". If we're in a
+middle of a dispatch cycle dispatching from queue Y and a request
+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.
+
+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
+means adding some extra time for serving a certain queue even if the
+queue is empty. The idling is enabled if we identify the application is
+inserting requests in a high frequency.
+
+For idling on READ queues we use timer mechanism. When the timer expires,
+if there are requests in the scheduler we will signal the underlying driver
+(for example the MMC driver) to fetch another request for dispatch.
+
+The ROW algorithm takes the scheduling policy one step further, making
+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
+supports High Priority Requests. That is, the scheduler may inform the
+device upon urgent requests using new callback make_urgent_request.
+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
+a case the device may also send back to the scheduler the reminder of
+the interrupted write request, such that the scheduler may continue
+sending high priority requests without the need to interrupt the
+ongoing write again and again. The write remainder will be sent later on
+according to the scheduler policy.
+
+Design
+======
+Existing algorithms (cfq, deadline) sort the io requests according LBA.
+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.
+
+SMP/multi-core
+==============
+At the moment the code is acceded from 2 contexts:
+- Application context (from block/elevator layer): adding the requests.
+- Underlying driver context (for example the mmc driver thread): dispatching
+ the requests and notifying on completion.
+
+One lock is used to synchronize between the two. This lock is provided
+by the underlying driver along with the dispatch queue.
+
+Config options
+==============
+1. hp_read_quantum: dispatch quantum for the high priority READ queue
+2. rp_read_quantum: dispatch quantum for the regular priority READ queue
+3. hp_swrite_quantum: dispatch quantum for the high priority Synchronous
+ WRITE queue
+4. rp_swrite_quantum: dispatch quantum for the regular priority
+ Synchronous WRITE queue
+5. rp_write_quantum: dispatch quantum for the regular priority WRITE
+ queue
+6. lp_read_quantum: dispatch quantum for the low priority READ queue
+7. lp_swrite_quantum: dispatch quantum for the low priority Synchronous
+ WRITE queue
+8. read_idle: how long to idle on read queue in Msec (in case idling
+ is enabled on that queue).
+9. read_idle_freq: frequency of inserting READ requests that will
+ trigger idling. This is the time in Msec between inserting two READ
+ requests
