2008-04-27ide-tape: remove remaining pipeline functionalityBorislav Petkov
The driver is using now solely its own request queue. - tape->next_stage is always NULL so it is safe to remove all code depending on tape->next_stage != NULL - this patch removes the last place which sets IDETAPE_FLAG_PIPELINE_ACTIVE in tape->flags [bart: add above explanations] Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-27ide-tape: unwrap idetape_queue_pc_tail()Borislav Petkov
idetape_queue_pc_tail() is a wrapper for its __idetape_queue_pc_tail() counterpart and has no other functionality. Remove it and call the "wrapped" function directly. Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-27ide-tape: remove idetape_pipeline_size()Borislav Petkov
The computation of the block offset of the the tape position (MTIOCPOS, MTIOCGET) is not influenced by the stages queued in the pipeline anymore but by the size of the current buffer which is going to be sent to the drive. [bart: resurrect deleted idetape_wait_for_pipeline() call] Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-27ide-tape: remove pipeline-specific code in idetape_space_over_filemarks()Borislav Petkov
Since we don't do pipeline read-ahead anymore, we don't have to look for filemarks we have crossed. Therefore, remove the code chunk that does that and pass on the command to the tape. As a side effect, remove unused idetape_wait_first_stage(). Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-27ide-tape: remove pipeline-specific code from idetape_add_chrdev_read_request()Borislav Petkov
In order to do away with queueing read requests on the pipeline, several things have to be done: 1. Do not allocate additional pipeline stages in idetape_init_read() until (tape->nr_stages < max_stages) and do only read operation preparations. As a collateral result, idetape_add_stage_tail() becomes unused so remove it. 2. Queue the read request's buffer directly thru idetape_queue_rw_tail(). 3. Remove now unused idetape_kmalloc_stage() and idetape_switch_buffers(). [bart: simplify the original patch] Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-27ide-tape remove pipeline speed/control calculationsBorislav Petkov
Pipeline handling calculations in idetape_calculate_speeds() can go since they do not have any effect on other functionality besides: 1. info is only being exported through /proc as a read-only item (controlled_pipeline_head_speed, uncontrolled_pipeline_head_speed) 2. used in idetape_restart_speed_control() which, in turn, is unrelated to other code 3. used only for pipeline frames number accounting (tape->pipeline_head), also unused elsewhere. 4.some variables are: only written to: tape->buffer_head; unused: tape->tape_head, tape->last_tape_head Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-27ide-tape: remove pipeline-specific code from idetape_add_chrdev_write_requestBorislav Petkov
Refrain from adding more write requests to the pipeline and queue them directly on the device's request queue instead. [bart: re-do for minimal behavior changes] Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-27ide-tape: remove tape->cache_stageBorislav Petkov
Prior to allocating a new pipeline stage, the code checked for the existence of a cached pipeline stage to use. Do away with and stick to normal pipeline stages only.

2008-04-27ide: add "ignore_cable" parameter (take 2)Bartlomiej Zolnierkiewicz
Add "ignore_cable" parameter: * "ide_core.ignore_cable=[interface_number]" boot option if IDE is built-in (i.e. "ide_core.ignore_cable=1" to force ignoring cable for "ide1") * "ignore_cable=[interface_number]" module parameter (for ide_core module) if IDE is compiled as module v2: * Add ide_port_apply_params() helper - use it in ide_device_add_all() and ide_scan_port(). * Make it possible to later disable ignoring cable detection by passing "[interface_number]:0" to /sys/module/ide_core/parameters/ignore_cable (however sysfs interface is not enabled yet since it needs some other IDE changes to make it work reliable).
