2007-07-13async_tx: add the async_tx apiDan Williams9-17/+1104
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. I imagine that any piece of ADMA hardware would register with the 'async_*' subsystem, and a call to async_X would be routed as appropriate, or be run in-line. - Neil Brown async_tx exploits the capabilities of struct dma_async_tx_descriptor to provide an api of the following general format: struct dma_async_tx_descriptor * async_<operation>(..., struct dma_async_tx_descriptor *depend_tx, dma_async_tx_callback cb_fn, void *cb_param) { struct dma_chan *chan = async_tx_find_channel(depend_tx, <operation>); struct dma_device *device = chan ? chan->device : NULL; int int_en = cb_fn ? 1 : 0; struct dma_async_tx_descriptor *tx = device ? device->device_prep_dma_<operation>(chan, len, int_en) : NULL; if (tx) { /* run <operation> asynchronously */ ... tx->tx_set_dest(addr, tx, index); ... tx->tx_set_src(addr, tx, index); ... async_tx_submit(chan, tx, flags, depend_tx, cb_fn, cb_param); } else { /* run <operation> synchronously */ ... <operation> ... async_tx_sync_epilog(flags, depend_tx, cb_fn, cb_param); } return tx; } async_tx_find_channel() returns a capable channel from its pool. The channel pool is organized as a per-cpu array of channel pointers. The async_tx_rebalance() routine is tasked with managing these arrays. In the uniprocessor case async_tx_rebalance() tries to spread responsibility evenly over channels of similar capabilities. For example if there are two copy+xor channels, one will handle copy operations and the other will handle xor. In the SMP case async_tx_rebalance() attempts to spread the operations evenly over the cpus, e.g. cpu0 gets copy channel0 and xor channel0 while cpu1 gets copy channel 1 and xor channel 1. When a dependency is specified async_tx_find_channel defaults to keeping the operation on the same channel. A xor->copy->xor chain will stay on one channel if it supports both operation types, otherwise the transaction will transition between a copy and a xor resource. Currently the raid5 implementation in the MD raid456 driver has been converted to the async_tx api. A driver for the offload engines on the Intel Xscale series of I/O processors, iop-adma, is provided in a later commit. With the iop-adma driver and async_tx, raid456 is able to offload copy, xor, and xor-zero-sum operations to hardware engines. On iop342 tiobench showed higher throughput for sequential writes (20 - 30% improvement) and sequential reads to a degraded array (40 - 55% improvement). For the other cases performance was roughly equal, +/- a few percentage points. On a x86-smp platform the performance of the async_tx implementation (in synchronous mode) was also +/- a few percentage points of the original implementation. According to 'top' on iop342 CPU utilization drops from ~50% to ~15% during a 'resync' while the speed according to /proc/mdstat doubles from ~25 MB/s to ~50 MB/s. The tiobench command line used for testing was: tiobench --size 2048 --block 4096 --block 131072 --dir /mnt/raid --numruns 5 * iop342 had 1GB of memory available Details: * if CONFIG_DMA_ENGINE=n the asynchronous path is compiled away by making async_tx_find_channel a static inline routine that always returns NULL * when a callback is specified for a given transaction an interrupt will fire at operation completion time and the callback will occur in a tasklet. if the the channel does not support interrupts then a live polling wait will be performed * the api is written as a dmaengine client that requests all available channels * In support of dependencies the api implicitly schedules channel-switch interrupts. The interrupt triggers the cleanup tasklet which causes pending operations to be scheduled on the next channel * Xor engines treat an xor destination address differently than a software xor routine. To the software routine the destination address is an implied source, whereas engines treat it as a write-only destination. This patch modifies the xor_blocks routine to take a an explicit destination address to mirror the hardware. Changelog: * fixed a leftover debug print * don't allow callbacks in async_interrupt_cond * fixed xor_block changes * fixed usage of ASYNC_TX_XOR_DROP_DEST * drop dma mapping methods, suggested by Chris Leech * printk warning fixups from Andrew Morton * don't use inline in C files, Adrian Bunk * select the API when MD is enabled * BUG_ON xor source counts <= 1 * implicitly handle hardware concerns like channel switching and interrupts, Neil Brown * remove the per operation type list, and distribute operation capabilities evenly amongst the available channels * simplify async_tx_find_channel to optimize the fast path * introduce the channel_table_initialized flag to prevent early calls to the api * reorganize the code to mimic crypto * include mm.h as not all archs include it in dma-mapping.h * make the Kconfig options non-user visible, Adrian Bunk * move async_tx under crypto since it is meant as 'core' functionality, and the two may share algorithms in the future * move large inline functions into c files * checkpatch.pl fixes * gpl v2 only correction Cc: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Acked-By: NeilBrown <neilb@suse.de>
2007-07-13xor: make 'xor_blocks' a library routine for use with async_txDan Williams3-0/+168
The async_tx api tries to use a dma engine for an operation, but will fall back to an optimized software routine otherwise. Xor support is implemented using the raid5 xor routines. For organizational purposes this routine is moved to a common area.

2007-05-19[CRYPTO] api: Read module pointer before freeing algorithmHerbert Xu1-1/+3
The function crypto_mod_put first frees the algorithm and then drops the reference to its module. Unfortunately we read the module pointer which after freeing the algorithm and that pointer sits inside the object that we just freed.

2007-05-02[CRYPTO] api: Do not remove users unless new algorithm matchesHerbert Xu1-26/+39
As it is whenever a new algorithm with the same name is registered users of the old algorithm will be removed so that they can take advantage of the new algorithm. This presents a problem when the new algorithm is not equivalent to the old algorithm. In particular, the new algorithm might only function on top of the existing one. Hence we should not remove users unless they can make use of the new algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2007-05-02[CRYPTO] templates: Pass type/mask when creating instancesHerbert Xu8-34/+103
This patch passes the type/mask along when constructing instances of templates. This is in preparation for templates that may support multiple types of instances depending on what is requested. For example, the planned software async crypto driver will use this construct. For the moment this allows us to check whether the instance constructed is of the correct type and avoid returning success if the type does not match.

2007-05-02[CRYPTO] tcrypt: Use async blkcipher interfaceHerbert Xu1-39/+82

2007-05-02[CRYPTO] api: Add async block cipher interfaceHerbert Xu1-5/+65
This patch adds the frontend interface for asynchronous block ciphers. In addition to the usual block cipher parameters, there is a callback function pointer and a data pointer. The callback will be invoked only if the encrypt/decrypt handlers return -EINPROGRESS. In other words, if the return value of zero the completion handler (or the equivalent code) needs to be invoked by the caller. The request structure is allocated and freed by the caller. Its size is determined by calling crypto_ablkcipher_reqsize(). The helpers ablkcipher_request_alloc/ablkcipher_request_free can be used to manage the memory for a request.

2007-03-21[CRYPTO] api: scatterwalk_copychunks() fails to advance through scatterlistJ. Bruce Fields1-2/+2
In the loop in scatterwalk_copychunks(), if walk->offset is zero, then scatterwalk_pagedone rounds that up to the nearest page boundary: walk->offset += PAGE_SIZE - 1; walk->offset &= PAGE_MASK; which is a no-op in this case, so we don't advance to the next element of the scatterlist array: if (walk->offset >= walk->sg->offset + walk->sg->length) scatterwalk_start(walk, sg_next(walk->sg)); and we end up copying the same data twice. It appears that other callers of scatterwalk_{page}done first advance walk->offset, so I believe that's the correct thing to do here. This caused a bug in NFS when run with krb5p security, which would cause some writes to fail with permissions errors--for example, writes of less than 8 bytes (the des blocksize) at the start of a file. A git-bisect shows the bug was originally introduced by 5c64097aa0f6dc4f27718ef47ca9a12538d62860, first in 2.6.19-rc1. Signed-off-by: "J.

A lot of cypher modes need multiplications in GF(2^128). LRW, ABL, GCM... I use functions from this library in my LRW implementation and I will also use them in my ABL (Arbitrary Block Length, an unencumbered (correct me if I am wrong, wide block cipher mode). Elements of GF(2^128) must be presented as u128 *, it encourages automatic and proper alignment. The library contains support for two different representations of GF(2^128), see the comment in gf128mul.h. There different levels of optimization (memory/speed tradeoff). The code is based on work by Dr Brian Gladman. Notable changes: - deletion of two optimization modes - change from u32 to u64 for faster handling on 64bit machines - support for 'bbe' representation in addition to the, already implemented, 'lle' representation. - move 'inline void' functions from header to 'static void' in the source file - update to use the linux coding style conventions The original can be found at: http://fp.gladman.plus.com/AES/modes.vc8.19-06-06.zip The copyright (and GPL statement) of the original author is preserved.
