It is implemented as a dmaengine client that smooths over\nthe details of different hardware offload engine implementations. Code\nthat is written to the api can optimize for asynchronous operation and the\napi will fit the chain of operations to the available offload resources. \n \n\tI imagine that any piece of ADMA hardware would register with the\n\t\u0027async_*\u0027 subsystem, and a call to async_X would be routed as\n\tappropriate, or be run in-line. - Neil Brown\n\nasync_tx exploits the capabilities of struct dma_async_tx_descriptor to\nprovide an api of the following general format:\n\nstruct dma_async_tx_descriptor *\nasync_\u003coperation\u003e(..., struct dma_async_tx_descriptor *depend_tx,\n\t\t\tdma_async_tx_callback cb_fn, void *cb_param)\n{\n\tstruct dma_chan *chan \u003d async_tx_find_channel(depend_tx, \u003coperation\u003e);\n\tstruct dma_device *device \u003d chan ? chan-\u003edevice : NULL;\n\tint int_en \u003d cb_fn ? 1 : 0;\n\tstruct dma_async_tx_descriptor *tx \u003d device ?\n\t\tdevice-\u003edevice_prep_dma_\u003coperation\u003e(chan, len, int_en) : NULL;\n\n\tif (tx) { /* run \u003coperation\u003e asynchronously */\n\t\t...\n\t\ttx-\u003etx_set_dest(addr, tx, index);\n\t\t...\n\t\ttx-\u003etx_set_src(addr, tx, index);\n\t\t...\n\t\tasync_tx_submit(chan, tx, flags, depend_tx, cb_fn, cb_param);\n\t} else { /* run \u003coperation\u003e synchronously */\n\t\t...\n\t\t\u003coperation\u003e\n\t\t...\n\t\tasync_tx_sync_epilog(flags, depend_tx, cb_fn, cb_param);\n\t}\n\n\treturn tx;\n}\n\nasync_tx_find_channel() returns a capable channel from its pool. The\nchannel pool is organized as a per-cpu array of channel pointers. The\nasync_tx_rebalance() routine is tasked with managing these arrays. In the\nuniprocessor case async_tx_rebalance() tries to spread responsibility\nevenly over channels of similar capabilities. For example if there are two\ncopy+xor channels, one will handle copy operations and the other will\nhandle xor. In the SMP case async_tx_rebalance() attempts to spread the\noperations evenly over the cpus, e.g. cpu0 gets copy channel0 and xor\nchannel0 while cpu1 gets copy channel 1 and xor channel 1. When a\ndependency is specified async_tx_find_channel defaults to keeping the\noperation on the same channel. A xor-\u003ecopy-\u003exor chain will stay on one\nchannel if it supports both operation types, otherwise the transaction will\ntransition between a copy and a xor resource.\n\nCurrently the raid5 implementation in the MD raid456 driver has been\nconverted to the async_tx api. A driver for the offload engines on the\nIntel Xscale series of I/O processors, iop-adma, is provided in a later\ncommit. With the iop-adma driver and async_tx, raid456 is able to offload\ncopy, xor, and xor-zero-sum operations to hardware engines.\n \nOn iop342 tiobench showed higher throughput for sequential writes (20 - 30%\nimprovement) and sequential reads to a degraded array (40 - 55%\nimprovement). For the other cases performance was roughly equal, +/- a few\npercentage points. On a x86-smp platform the performance of the async_tx\nimplementation (in synchronous mode) was also +/- a few percentage points\nof the original implementation. According to \u0027top\u0027 on iop342 CPU\nutilization drops from ~50% to ~15% during a \u0027resync\u0027 while the speed\naccording to /proc/mdstat doubles from ~25 MB/s to ~50 MB/s.\n \nThe tiobench command line used for testing was: tiobench --size 2048\n--block 4096 --block 131072 --dir /mnt/raid --numruns 5\n* iop342 had 1GB of memory available\n\nDetails:\n* if CONFIG_DMA_ENGINE\u003dn the asynchronous path is compiled away by making\n async_tx_find_channel a static inline routine that always returns NULL\n* when a callback is specified for a given transaction an interrupt will\n fire at operation completion time and the callback will occur in a\n tasklet. if the the channel does not support interrupts then a live\n polling wait will be performed\n* the api is written as a dmaengine client that requests all available\n channels\n* In support of dependencies the api implicitly schedules channel-switch\n interrupts. The interrupt triggers the cleanup tasklet which causes\n pending operations to be scheduled on the next channel\n* Xor engines treat an xor destination address differently than a software\n xor routine. To the software routine the destination address is an implied\n source, whereas engines treat it as a write-only destination.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "b82631581372dc00b3507cedc3ad47af29efe962", "tree": "b8bcf35b3c7e9efe755da4e2bad38b7a6384e082", "parents": [ "64d2f0855e50a7185546ee1fbc03c2badc31330f" ], "author": { "name": "Henrik Kretzschmar", "email": "henne@nachtwindheim.de", "time": "Fri Jul 21 14:50:13 2006 -0700" }, "committer": { "name": "David S.
