2009-04-19ide-tape: use standard data transfer mechanismTejun Heo
Impact: use standard way to transfer data ide-tape uses rq in an interesting way. For r/w requests, rq->special is used to carry a private buffer management structure idetape_bh and rq->nr_sectors and current_nr_sectors are initialized to the number of idetape blocks which isn't necessary 512 bytes. Also, rq->current_nr_sectors is used to report back the residual count in units of idetape blocks. This peculiarity taxes both block layer and ide. ide-atapi has different paths and hooks to accomodate it and what a rq means becomes quite confusing and making changes at the block layer becomes quite difficult and error-prone. This patch makes ide-tape use bio instead. With the previous patch, ide-tape currently is using single contiguos buffer so replacing it isn't difficult. Data buffer is mapped into bio using blk_rq_map_kern() in idetape_queue_rw_tail(). idetape_io_buffers() and idetape_update_buffers() are dropped and pc->bh is set to null to tell ide-atapi to use standard data transfer mechanism and idetape_bh byte counts are updated by the issuer on completion using the residual count. This change also nicely removes the FIXME in ide_pc_intr() where ide-tape rqs need to be completed using ide_rq_bytes() instead of blk_rq_bytes() (although this didn't really matter as the request didn't have bio).

2009-04-19ide-tape: use single continuous bufferTejun Heo
Impact: simpler buffer allocation and handling, kills OOM, fix DMA transfers ide-tape has its own multiple buffer mechanism using struct idetape_bh. It allocates buffer with decreasing order-of-two allocations so that it results in minimum number of segments. However, the implementation is quite complex and works in a way that no other block or ide driver works necessitating a lot of special case handling. The benefit this complex allocation scheme brings is questionable as PIO or DMA the number of segments (16 maximum) doesn't make any noticeable difference and it also doesn't negate the need for multiple order allocation which can fail under memory pressure or high fragmentation although it does lower the highest order necessary by one when the buffer size isn't power of two. As the first step to remove the custom buffer management, this patch makes ide-tape allocate single continous buffer. The maximum order is four. I doubt the change would cause any trouble but if it ever matters, it should be converted to regular sg mechanism like everyone else and even in that case dropping custom buffer handling and moving to standard mechanism first make sense as an intermediate step. This patch makes the first bh to contain the whole buffer and drops multi bh handling code. Following patches will make further changes. This patch has the side effect of killing OOM triggered by allocation path and fixing DMA transfers. Previously, bug in alloc path triggered OOM on command issue and commands were passed to DMA engine without DMA-mapping all the segments. Signed-off-by: Tejun Heo <tj@kernel.org>
2009-04-19ide-atapi,tape,floppy: allow ->pc_callback() to change rq->data_lenTejun Heo
Impact: allow residual count implementation in ->pc_callback() rq->data_len has two duties - carrying the number of input bytes on issue and carrying residual count back to the issuer on completion. ide-atapi completion callback ->pc_callback() is the right place to do this but currently ide-atapi depends on rq->data_len carrying the original request size after calling ->pc_callback() to complete the pc request. This patch makes ide_pc_intr(), ide_tape_issue_pc() and ide_floppy_issue_pc() cache length to complete before calling ->pc_callback() so that it can modify rq->data_len as necessary. Note: As using rq->data_len for two purposes can make cases like this incorrect in subtle ways, future changes will introduce separate field for residual count.

2009-04-19ide-tape,floppy: fix failed command completion after request senseTejun Heo
Impact: fix infinite retry loop After a command failed, ide-tape and floppy inserts REQUEST_SENSE in front of the failed command and according to the result, sets pc->retries, flags and errors. After REQUEST_SENSE is complete, the failed command is again at the front of the queue and if the verdict was to terminate the request, the issue functions tries to complete it directly by calling drive->pc_callback() and returning ide_stopped. However, drive->pc_callback() doesn't complete a request. It only prepares for completion of the request. As a result, this creates an infinite loop where the failed request is retried perpetually. Fix it by actually ending the request by calling ide_complete_rq(). Signed-off-by: Tejun Heo <tj@kernel.org>
2009-04-19ide-pm: don't abuse rq->dataTejun Heo
Impact: cleanup rq->data usage ide-pm uses rq->data to carry pointer to struct request_pm_state through request queue and rq->special is used to carray pointer to local struct ide_cmd, which isn't necessary. Use rq->special for request_pm_state instead and use local ide_cmd in ide_start_power_step(). Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Jens Axboe <axboe@kernel.dk>
2009-04-19ide-cd,atapi: use bio for internal commandsTejun Heo
Impact: unify request data buffer handling rq->data is used mostly to pass kernel buffer through request queue without using bio. There are only a couple of places which still do this in kernel and converting to bio isn't difficult. This patch converts ide-cd and atapi to use bio instead of rq->data for request sense and internal pc commands. With previous change to unify sense request handling, this is relatively easily achieved by adding blk_rq_map_kern() during sense_rq prep and PC issue. If blk_rq_map_kern() fails for sense, the error is deferred till sense issue and aborts the failed command which triggered the sense. Note that this is a slim possibility as sense prep is done on each command issue, so for the above condition to actually trigger, all preps since the last sense issue till the issue of the request which would require a sense should fail. * do_request functions might sleep now. This should be okay as ide request_fn - do_ide_request() - is invoked only from make_request and plug work. Make sure this is the case by adding might_sleep() to do_ide_request(). * Functions which access the read sense data before the sense request is complete now should access bio_data(sense_rq->bio) as the sense buffer might have been copied during blk_rq_map_kern(). * ide-tape updated to map sg. * cdrom_do_block_pc() now doesn't have to deal with REQ_TYPE_ATA_PC special case. Simplified. * tp_ops->output/input_data path dropped from ide_pc_intr(). Signed-off-by: Tejun Heo <tj@kernel.org>
2009-04-19ide-atapi: convert ide-{floppy,tape} to using preallocated sense bufferBorislav Petkov
Since we're issuing REQ_TYPE_SENSE now we need to allow those types of rqs in the ->do_request callbacks. As a future improvement, sense_len assignment might be unified across all ATAPI devices. Borislav to check with specs and test. As a result, get rid of ide_queue_pc_head() and drive->request_sense_rq. tj: * Init request sense ide_atapi_pc from sense request. In the longer timer, it would probably better to fold ide_create_request_sense_cmd() into its only current user - ide_floppy_get_format_progress(). * ide_retry_pc() no longer takes @disk.

2009-04-19ide-cd: convert to using generic sense requestBorislav Petkov
Preallocate a sense request in the ->do_request method and reinitialize it only on demand, in case it's been consumed in the IRQ handler path. The reason for this is that we don't want to be mapping rq to bio in the IRQ path and introduce all kinds of unnecessary hacks to the block layer. tj: * Both user and kernel PC requests expect sense data to be stored in separate storage other than drive->sense_data. Copy sense data to rq->sense on completion if rq->sense is not NULL. This fixes bogus sense data on PC requests. As a result, remove cdrom_queue_request_sense.

2009-04-19ide: add helpers for preparing sense requestsBorislav Petkov
This is in preparation of removing the queueing of a sense request out of the IRQ handler path. Use struct request_sense as a general sense buffer for all ATAPI devices ide-{floppy,tape,cd}. tj: * blk_get_request(__GFP_WAIT) can't be called from do_request() as it can cause deadlock. Converted to use inline struct request and blk_rq_init(). * Added xfer / cdb len selection depending on device type. * All sense prep logics folded into ide_prep_sense() which never fails. * hwif->rq clearing and sense_rq used handling moved into ide_queue_sense_rq(). * blk_rq_map_kern() conversion is moved to later patch.

2009-04-19ide-taskfile: don't abuse rq->bufferTejun Heo
Impact: rq->buffer usage cleanup ide_raw_taskfile() directly uses rq->buffer to carry pointer to the data buffer. This complicates both block interface and ide backend request handling. Use blk_rq_map_kern() instead and drop special handling for REQ_TYPE_ATA_TASKFILE from ide_map_sg(). Note that REQ_RW setting is moved upwards as blk_rq_map_kern() uses it to initialize bio rw flag.

Impact: remove unnecessary code path Block pc requests always use bio and rq->data is always NULL. No need to worry about !rq->bio cases in idefloppy_block_pc_cmd().

Kill back-to-back REQUEST_SENSE detection. Signed-off-by: Tejun Heo <tj@kernel.org>
2009-04-19block: clear req->errors on bio completion only for fs requestsTejun Heo
Impact: subtle behavior change For fs requests, rq is only carrier of bios and rq error status as a whole doesn't mean much. This is the reason why rq->errors is being cleared on each partial completion of a request as on each partial completion the error status is transferred to the respective bios. For pc requests, rq->errors is used to carry error status to the issuer and thus __end_that_request_first() doesn't clear it on such cases. The condition was fine till now as only fs and pc requests have used bio and thus the bio completion path. However, future changes will unify data accesses to bio and all non fs users care about rq error status. Clear rq->errors on bio completion only for fs requests. In general, the implicit clearing is a bit too subtle especially as the meaning of rq->errors is completely dependent on low level drivers. Unifying / cleaning up rq->errors usage and letting llds manage it would be better. TODO comment added. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Jens Axboe <axboe@kernel.dk>

Workaround for errata SATA#24 in sata_mv. This errata affects WRITE_MULTI* commands when the device multi_count produces a DRQ block size >= 4Kbytes. We work around it here by converting such operations into ordinary PIO_WRITEs instead. Note that this might result in a PIO FUA write unavoidably being converted into a non-FUA write. In practice, any system using FUA is also going to be using DMA rather than PIO, so this shouldn't affect anyone in the real world.
