The \u0027get_stripe_work\u0027 routine\nruns under the lock to read all the bits in sh-\u003eops.pending that do not\nhave the corresponding bit set in sh-\u003eops.ack. This modified \u0027pending\u0027\nbitmap is then passed to raid5_run_ops for processing.\n\nThe transition from \u0027ack\u0027 to \u0027completion\u0027 does not need similar protection\nas the existing release_stripe infrastructure will guarantee that\nhandle_stripe will run again after a completion bit is set, and\nhandle_stripe can tolerate a sh-\u003eops.completed bit being set while the lock\nis held.\n\nA call to async_tx_issue_pending_all() is added to raid5d to kick the\noffload engines once all pending stripe operations work has been submitted.\nThis enables batching of the submission and completion of operations.\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nAcked-By: NeilBrown \u003cneilb@suse.de\u003e\n" }, { "commit": "91c00924846a0034020451c280c76baa4299f9dc", "tree": "7124ed6706937b793a10c37a861c5fc0f2e5b348", "parents": [ "45b4233caac05da0118b608a9fc2a40a9fc580cd" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Tue Jan 02 13:52:30 2007 -0700" }, "committer": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Fri Jul 13 08:06:15 2007 -0700" }, "message": "md: raid5_run_ops - run stripe operations outside sh-\u003elock\n\nWhen the raid acceleration work was proposed, Neil laid out the following\nattack plan:\n\n1/ move the xor and copy operations outside spin_lock(\u0026sh-\u003elock)\n2/ find/implement an asynchronous offload api\n\nThe raid5_run_ops routine uses the asynchronous offload api (async_tx) and\nthe stripe_operations member of a stripe_head to carry out xor+copy\noperations asynchronously, outside the lock.\n\nTo perform operations outside the lock a new set of state flags is needed\nto track new requests, in-flight requests, and completed requests. In this\nnew model handle_stripe is tasked with scanning the stripe_head for work,\nupdating the stripe_operations structure, and finally dropping the lock and\ncalling raid5_run_ops for processing. The following flags outline the\nrequests that handle_stripe can make of raid5_run_ops:\n\nSTRIPE_OP_BIOFILL\n - copy data into request buffers to satisfy a read request\nSTRIPE_OP_COMPUTE_BLK\n - generate a missing block in the cache from the other blocks\nSTRIPE_OP_PREXOR\n - subtract existing data as part of the read-modify-write process\nSTRIPE_OP_BIODRAIN\n - copy data out of request buffers to satisfy a write request\nSTRIPE_OP_POSTXOR\n - recalculate parity for new data that has entered the cache\nSTRIPE_OP_CHECK\n - verify that the parity is correct\nSTRIPE_OP_IO\n - submit i/o to the member disks (note this was already performed outside\n the stripe lock, but it made sense to add it as an operation type\n\nThe flow is:\n1/ handle_stripe sets STRIPE_OP_* in sh-\u003eops.pending\n2/ raid5_run_ops reads sh-\u003eops.pending, sets sh-\u003eops.ack, and submits the\n operation to the async_tx api\n3/ async_tx triggers the completion callback routine to set\n sh-\u003eops.complete and release the stripe\n4/ handle_stripe runs again to finish the operation and optionally submit\n new operations that were previously blocked\n\nNote this patch just defines raid5_run_ops, subsequent commits (one per\nmajor operation type) modify handle_stripe to take advantage of this\nroutine.\n\nChangelog:\n* removed ops_complete_biodrain in favor of ops_complete_postxor and\n ops_complete_write.\n* removed the raid5_run_ops workqueue\n* call bi_end_io for reads in ops_complete_biofill, saves a call to\n handle_stripe\n* explicitly handle the 2-disk raid5 case (xor becomes memcpy), Neil Brown\n* fix race between async engines and bi_end_io call for reads, Neil Brown\n* remove unnecessary spin_lock from ops_complete_biofill\n* remove test_and_set/test_and_clear BUG_ONs, Neil Brown\n* remove explicit interrupt handling for channel switching, this feature\n was absorbed (i.e. it is now implicit) by the async_tx api\n* use return_io in ops_complete_biofill\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nAcked-By: NeilBrown \u003cneilb@suse.de\u003e\n" } ], "next": "45b4233caac05da0118b608a9fc2a40a9fc580cd" }
