Currently CFQ uses a\ndoubly linked list per priority level for sorting and service uses.\nKill those lists and maintain an rbtree of cfq_queue\u0027s, sorted by when\nto service them.\n\nThis unfortunately means that the ionice levels aren\u0027t as strong\nanymore, will work on improving those later. We only scale the slice\ntime now, not the number of times we service. This means that latency\nis better (for all priority levels), but that the distinction between\nthe highest and lower levels aren\u0027t as big.\n\nThe diffstat speaks for itself.\n\n cfq-iosched.c | 363 +++++++++++++++++---------------------------------\n 1 file changed, 125 insertions(+), 238 deletions(-)\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "1afba0451c83cbff622a08f2d86fbb2e680dfd5f", "tree": "7da7b97114b73d6d9788cf8663cd3aa28433c0dd", "parents": [ "6d048f5310aa2dda2b5acd947eab3598c25e269f" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Apr 17 12:47:55 2007 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Mon Apr 30 09:01:21 2007 +0200" }, "message": "cfq-iosched: minor updates\n\n- Move the queue_new flag clear to when the queue is selected\n- Only select the non-first queue in cfq_get_best_queue(), if there\u0027s\n a substantial difference between the best and first.\n- Get rid of -\u003ebusy_rr\n- Only select a close cooperator, if the current queue is known to take\n a while to \"think\".\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "6d048f5310aa2dda2b5acd947eab3598c25e269f", "tree": "4f0dbcd21b82dd015a908139fb4de3601b3d834a", "parents": [ "1e3335de05da3dfbe48b8caa03db1834a2133256" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Wed Apr 25 12:44:27 2007 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Mon Apr 30 09:01:21 2007 +0200" }, "message": "cfq-iosched: development update\n\n- Implement logic for detecting cooperating processes, so we\n choose the best available queue whenever possible.\n\n- Improve residual slice time accounting.\n\n- Remove dead code: we no longer see async requests coming in on\n sync queues.
