+
+1 INTRODUCTION
+
+The async_tx API provides methods for describing a chain of asynchronous
+bulk memory transfers/transforms with support for inter-transactional
+dependencies. It is implemented as a dmaengine client that smooths over
+the details of different hardware offload engine implementations. Code
+that is written to the API can optimize for asynchronous operation and
+the API will fit the chain of operations to the available offload
+resources.
+
+2 GENEALOGY
+
+The API was initially designed to offload the memory copy and
+xor-parity-calculations of the md-raid5 driver using the offload engines
+present in the Intel(R) Xscale series of I/O processors. It also built
+on the 'dmaengine' layer developed for offloading memory copies in the
+network stack using Intel(R) I/OAT engines. The following design
+features surfaced as a result:
+1/ implicit synchronous path: users of the API do not need to know if
+ the platform they are running on has offload capabilities. The
+ operation will be offloaded when an engine is available and carried out
+ in software otherwise.
+2/ cross channel dependency chains: the API allows a chain of dependent
+ operations to be submitted, like xor->copy->xor in the raid5 case. The
+ API automatically handles cases where the transition from one operation
+ to another implies a hardware channel switch.
+3/ dmaengine extensions to support multiple clients and operation types
+ beyond 'memcpy'
+
+3 USAGE
+
+3.1 General format of the API:
+struct dma_async_tx_descriptor *
+async_<operation>(<op specific parameters>,
+ enum async_tx_flags flags,
+ struct dma_async_tx_descriptor *dependency,
+ dma_async_tx_callback callback_routine,
+ void *callback_parameter);
+
+3.2 Supported operations:
+memcpy - memory copy between a source and a destination buffer
+memset - fill a destination buffer with a byte value
+xor - xor a series of source buffers and write the result to a
+ destination buffer
+xor_zero_sum - xor a series of source buffers and set a flag if the
+ result is zero. The implementation attempts to prevent
+ writes to memory
+
+3.3 Descriptor management:
+The return value is non-NULL and points to a 'descriptor' when the operation
+has been queued to execute asynchronously. Descriptors are recycled
+resources, under control of the offload engine driver, to be reused as
+operations complete. When an application needs to submit a chain of
+operations it must guarantee that the descriptor is not automatically recycled
+before the dependency is submitted. This requires that all descriptors be
+acknowledged by the application before the offload engine driver is allowed to
+recycle (or free) the descriptor. A descriptor can be acked by one of the
+following methods:
+1/ setting the ASYNC_TX_ACK flag if no child operations are to be submitted
+2/ setting the ASYNC_TX_DEP_ACK flag to acknowledge the parent
+ descriptor of a new operation.
+3/ calling async_tx_ack() on the descriptor.
+
+3.4 When does the operation execute?
+Operations do not immediately issue after return from the
+async_<operation> call. Offload engine drivers batch operations to
+improve performance by reducing the number of mmio cycles needed to
+manage the channel. Once a driver-specific threshold is met the driver
+automatically issues pending operations. An application can force this
+event by calling async_tx_issue_pending_all(). This operates on all
+channels since the application has no knowledge of channel to operation
+mapping.
+
+3.5 When does the operation complete?
+There are two methods for an application to learn about the completion
+of an operation.
+1/ Call dma_wait_for_async_tx(). This call causes the CPU to spin while
+ it polls for the completion of the operation. It handles dependency
+ chains and issuing pending operations.
+2/ Specify a completion callback. The callback routine runs in tasklet
+ context if the offload engine driver supports interrupts, or it is
+ called in application context if the operation is carried out
+ synchronously in software. The callback can be set in the call to
+ async_<operation>, or when the application needs to submit a chain of
+ unknown length it can use the async_trigger_callback() routine to set a
+ completion interrupt/callback at the end of the chain.
+
+3.6 Constraints:
+1/ Calls to async_<operation> are not permitted in IRQ context. Other
+ contexts are permitted provided constraint #2 is not violated.
+2/ Completion callback routines cannot submit new operations. This
+ results in recursion in the synchronous case and spin_locks being
+ acquired twice in the asynchronous case.
+
+3.7 Example:
+Perform a xor->copy->xor operation where each operation depends on the
+result from the previous operation:
+
+void complete_xor_copy_xor(void *param)
+{
+ printk("complete\n");
+}
+
+int run_xor_copy_xor(struct page **xor_srcs,
+ int xor_src_cnt,
+ struct page *xor_dest,
+ size_t xor_len,
+ struct page *copy_src,
+ struct page *copy_dest,
+ size_t copy_len)
+{
+ struct dma_async_tx_descriptor *tx;
+
+ tx = async_xor(xor_dest, xor_srcs, 0, xor_src_cnt, xor_len,
+ ASYNC_TX_XOR_DROP_DST, NULL, NULL, NULL);
+ tx = async_memcpy(copy_dest, copy_src, 0, 0, copy_len,
+ ASYNC_TX_DEP_ACK, tx, NULL, NULL);
+ tx = async_xor(xor_dest, xor_srcs, 0, xor_src_cnt, xor_len,
+ ASYNC_TX_XOR_DROP_DST | ASYNC_TX_DEP_ACK | ASYNC_TX_ACK,
+ tx, complete_xor_copy_xor, NULL);
+
+ async_tx_issue_pending_all();
+}
+
+See include/linux/async_tx.h for more information on the flags. See the
+ops_run_* and ops_complete_* routines in drivers/md/raid5.c for more
+implementation examples.
+
+4 DRIVER DEVELOPMENT NOTES
+4.1 Conformance points:
+There are a few conformance points required in dmaengine drivers to
+accommodate assumptions made by applications using the async_tx API:
+1/ Completion callbacks are expected to happen in tasklet context
+2/ dma_async_tx_descriptor fields are never manipulated in IRQ context
+3/ Use async_tx_run_dependencies() in the descriptor clean up path to
+ handle submission of dependent operations
+
+4.2 "My application needs finer control of hardware channels"
+This requirement seems to arise from cases where a DMA engine driver is
+trying to support device-to-memory DMA. The dmaengine and async_tx
+implementations were designed for offloading memory-to-memory
+operations; however, there are some capabilities of the dmaengine layer
+that can be used for platform-specific channel management.
+Platform-specific constraints can be handled by registering the
+application as a 'dma_client' and implementing a 'dma_event_callback' to
+apply a filter to the available channels in the system. Before showing
+how to implement a custom dma_event callback some background of
+dmaengine's client support is required.
+
+The following routines in dmaengine support multiple clients requesting
+use of a channel:
+- dma_async_client_register(struct dma_client *client)
+- dma_async_client_chan_request(struct dma_client *client)
+
+dma_async_client_register takes a pointer to an initialized dma_client
+structure. It expects that the 'event_callback' and 'cap_mask' fields
+are already initialized.
+
+dma_async_client_chan_request triggers dmaengine to notify the client of
+all channels that satisfy the capability mask. It is up to the client's
+event_callback routine to track how many channels the client needs and
+how many it is currently using. The dma_event_callback routine returns a
+dma_state_client code to let dmaengine know the status of the
+allocation.
+
+Below is the example of how to extend this functionality for
+platform-specific filtering of the available channels beyond the
+standard capability mask:
+
+static enum dma_state_client
+my_dma_client_callback(struct dma_client *client,
+ struct dma_chan *chan, enum dma_state state)
+{
+ struct dma_device *dma_dev;
+ struct my_platform_specific_dma *plat_dma_dev;
+
+ dma_dev = chan->device;
+ plat_dma_dev = container_of(dma_dev,
+ struct my_platform_specific_dma,
+ dma_dev);
+
+ if (!plat_dma_dev->platform_specific_capability)
+ return DMA_DUP;
+
+ . . .
+}

+LOCK STATISTICS
+
+- WHAT
+
+As the name suggests, it provides statistics on locks.
+
+- WHY
+
+Because things like lock contention can severely impact performance.
+
+- HOW
+
+Lockdep already has hooks in the lock functions and maps lock instances to
+lock classes. We build on that. The graph below shows the relation between
+the lock functions and the various hooks therein.
+
+ __acquire
+ |
+ lock _____
+ | \
+ | __contended
+ | |
+ | <wait>
+ | _______/
+ |/
+ |
+ __acquired
+ |
+ .
+ <hold>
+ .
+ |
+ __release
+ |
+ unlock
+
+lock, unlock - the regular lock functions
+__* - the hooks
+<> - states
+
+With these hooks we provide the following statistics:
+
+ con-bounces - number of lock contention that involved x-cpu data
+ contentions - number of lock acquisitions that had to wait
+ wait time min - shortest (non-0) time we ever had to wait for a lock
+ max - longest time we ever had to wait for a lock
+ total - total time we spend waiting on this lock
+ acq-bounces - number of lock acquisitions that involved x-cpu data
+ acquisitions - number of times we took the lock
+ hold time min - shortest (non-0) time we ever held the lock
+ max - longest time we ever held the lock
+ total - total time this lock was held
+
+From these number various other statistics can be derived, such as:
+
+ hold time average = hold time total / acquisitions
+
+These numbers are gathered per lock class, per read/write state (when
+applicable).
+
+It also tracks 4 contention points per class. A contention point is a call site
+that had to wait on lock acquisition.
+
+ - USAGE
+
