2005-10-28[libata scsi] MODE SELECT, strengthen mode senseDouglas Gilbert1-41/+103
- move default mode pages to the front of libata-scsi.c so various functions can access them - partial annotation of these pages, point out divergence from sat-r06 - replace various mode page magic numbers with defines - strengthen MODE SENSE command decoding: handle DBD bit in cdb, yield block descriptor (per sat-r06) and handle mode sub pages Signed-off-by: Douglas Gilbert <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

- 100msec sleep is a little excessive, lots of requests can complete in that timeframe. Use 10msec instead. - Rename QUEUE_FLAG_BYPASS to QUEUE_FLAG_ELVSWITCH to indicate what is going on. Signed-off-by: Jens Axboe <[email protected]>
2005-10-28[BLOCK] Reimplement elevator switchTejun Heo2-158/+62
This patch reimplements elevator switch. This patch assumes generic dispatch queue patchset is applied. * Each request is tagged with REQ_ELVPRIV flag if it has its elevator private data set. * Requests which doesn't have REQ_ELVPRIV flag set never enter iosched. They are always directly back inserted to dispatch queue. Of course, elevator_put_req_fn is called only for requests which have its REQ_ELVPRIV set. * Request queue maintains the current number of requests which have its elevator data set (elevator_set_req_fn called) in q->rq->elvpriv. * If a request queue has QUEUE_FLAG_BYPASS set, elevator private data is not allocated for new requests. To switch to another iosched, we set QUEUE_FLAG_BYPASS and wait until elvpriv goes to zero; then, we attach the new iosched and clears QUEUE_FLAG_BYPASS. New implementation is much simpler and main code paths are less cluttered, IMHO. Signed-off-by: Tejun Heo <[email protected]> Signed-off-by: Jens Axboe <[email protected]>

2005-10-28[PATCH] 03/05 move last_merge handlin into generic elevator codeTejun Heo1-25/+18

2005-10-28[PATCH] 02/05: update ioscheds to use generic dispatch queueJens Axboe4-555/+187
This patch updates all four ioscheds to use generic dispatch queue. There's one behavior change in as-iosched. * In as-iosched, when force dispatching (ELEVATOR_INSERT_BACK), batch_data_dir is reset to REQ_SYNC and changed_batch and new_batch are cleared to zero. This prevernts AS from doing incorrect update_write_batch after the forced dispatched requests are finished. * In cfq-iosched, cfqd->rq_in_driver currently counts the number of activated (removed) requests to determine whether queue-kicking is needed and cfq_max_depth has been reached. With generic dispatch queue, I think counting the number of dispatched requests would be more appropriate. * cfq_max_depth can be lowered to 1 again. Original from Tejun Heo, modified version applied. Signed-off-by: Jens Axboe <[email protected]>

2005-10-28[PATCH] 01/05 Implement generic dispatch queueTejun Heo2-82/+183
Implements generic dispatch queue which can replace all dispatch queues implemented by each iosched.

2005-10-28[PATCH] fix try_module_get race in elevator_findTejun Heo1-10/+14
This patch removes try_module_get race in elevator_find. try_module_get should always be called with the spinlock protecting what the module init/cleanup routines register/unregister to held. In the case of elevators, we should be holding elv_list to avoid it going away between spin_unlock_irq and try_module_get.

2005-10-28[patch] remove gendisk->stamp_idle fieldChen, Kenneth W1-6/+5
struct gendisk has these two fields: stamp, stamp_idle. Update to stamp_idle is always in sync with stamp and they are always the same. Therefore, it does not add any value in having two fields tracking same timestamp. Suggest to remove it. Also, we should only update gendisk stats with non-zero value. Advantage is that we don't have to needlessly calculate memory address, and then add zero to the content. Signed-off-by: Ken Chen <[email protected]> Signed-off-by: Jens Axboe <[email protected]>

2005-10-25PCI: be more verbose about resource quirksLinus Torvalds1-13/+88
When reserving an PCI quirk, note that in the kernel bootup messages. Also, parse the strange PIIX4 device resources - they should get their own PCI resource quirks, but for now just print out what it finds to verify that the code does the right thing.

2005-10-25[PATCH] qlogic lockup fixAndrew Morton1-1/+2
If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call qla2x00_free_device() to clean up. But because ha->dpc_pid hasn't been set yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started yet. It does wait_for_completion() against an uninitialised completion struct and the kernel hangs up. Fix it by initialising ha->dpc_pid a bit earlier.

2005-10-23cardbus: limit IO windows to 256 bytesLinus Torvalds1-1/+1
That's what we've always historically done, and bigger windows seem to confuse some cardbus bridges. Or something. Alan reports that this makes the ThinkPad 600x series work properly again: the 4kB IO window for some reason made IDE DMA not work, which makes IDE painfully slow even if it works after DMA timeouts.
