2008-04-21block: move the padding adjustment to blk_rq_map_sgFUJITA Tomonori
blk_rq_map_user adjusts bi_size of the last bio. It breaks the rule that req->data_len (the true data length) is equal to sum(bio). It broke the scsi command completion code. commit e97a294ef6938512b655b1abf17656cf2b26f709 was introduced to fix the above issue. However, the partial completion code doesn't work with it. The commit is also a layer violation (scsi mid-layer should not know about the block layer's padding). This patch moves the padding adjustment to blk_rq_map_sg (suggested by James). The padding works like the drain buffer. This patch breaks the rule that req->data_len is equal to sum(sg), however, the drain buffer already broke it. So this patch just restores the rule that req->data_len is equal to sub(bio) without breaking anything new. Now when a low level driver needs padding, blk_rq_map_user and blk_rq_map_user_iov guarantee there's enough room for padding. blk_rq_map_sg can safely extend the last entry of a scatter list. blk_rq_map_sg must extend the last entry of a scatter list only for a request that got through bio_copy_user_iov. This patches introduces new REQ_COPY_USER flag.

2008-04-17libata: kill ata_noop_dev_select()Tejun Heo
Now that SFF assumptions are separated out from non-SFF reset sequence, port_ops->sff_dev_select() is no longer necessary for non-SFF controllers. Kill ata_noop_dev_select() and ->sff_dev_select initialization from base and other non-SFF port_ops. Signed-off-by: Tejun Heo <htejun@gmail.com>
2008-04-17libata: remove check_status from non-SFF driversTejun Heo

2008-04-17libata: replace tf_read with qc_fill_rtf for non-SFF driversTejun Heo
Now that all SFF stuff is separated out of core layer, core layer doesn't call ops->tf_read directly. It gets called only via ops->qc_fill_rtf() for non-SFF drivers. This patch directly implements private ops->qc_fill_rtf() for non-SFF controllers and kill ops->tf_read(). This is much cleaner for non-SFF controllers as some of them have to cache SFF register values in private data structure and report the cached values via ops->tf_read(). Also, ops->tf_read() gets nasty for controllers which don't have clear notion of TF registers when operation is not in progress. As this change makes default ops->qc_fill_rtf unnecessary, move ata_sff_qc_fill_rtf() form ata_base_port_ops to ata_sff_port_ops where it belongs. Signed-off-by: Tejun Heo <htejun@gmail.com>
2008-04-17libata: add qc_fill_rtf port operationTejun Heo
On command completion, ata_qc_complete() directly called ops->tf_read to fill qc->result_tf. This patch adds ops->qc_fill_rtf to replace hardcoded ops->tf_read usage. ata_sff_qc_fill_rtf() which uses ops->tf_read to fill result_tf is implemented and set in ata_base_port_ops and other ops tables which don't inherit from ata_base_port_ops, so this patch doesn't introduce any behavior change. ops->qc_fill_rtf() is similar to ops->sff_tf_read() but can only be called when a command finishes. As some non-SFF controllers don't have TF registers defined unless they're associated with in-flight commands, this limited operation makes life easier for those drivers and help lifting SFF assumptions from libata core layer. Signed-off-by: Tejun Heo <htejun@gmail.com>
2008-04-17libata: rename SFF port opsTejun Heo
Add sff_ prefix to SFF specific port ops. This rename is in preparation of separating SFF support out of libata core layer. This patch strictly renames ops and doesn't introduce any behavior difference. Signed-off-by: Tejun Heo <htejun@gmail.com>
2008-04-17libata: make reset related methods proper port operationsTejun Heo
Currently reset methods are not specified directly in the ata_port_operations table. If a LLD wants to use custom reset methods, it should construct and use a error_handler which uses those reset methods. It's done this way for two reasons. First, the ops table already contained too many methods and adding four more of them would noticeably increase the amount of necessary boilerplate code all over low level drivers. Second, as ->error_handler uses those reset methods, it can get confusing. ie. By overriding ->error_handler, those reset ops can be made useless making layering a bit hazy. Now that ops table uses inheritance, the first problem doesn't exist anymore. The second isn't completely solved but is relieved by providing default values - most drivers can just override what it has implemented and don't have to concern itself about higher level callbacks. In fact, there currently is no driver which actually modifies error handling behavior. Drivers which override ->error_handler just wraps the standard error handler only to prepare the controller for EH. I don't think making ops layering strict has any noticeable benefit. This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and their PMP counterparts propoer ops. Default ops are provided in the base ops tables and drivers are converted to override individual reset methods instead of creating custom error_handler. * ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs aren't accessible. sata_promise doesn't need to use separate error_handlers for PATA and SATA anymore. * softreset is broken for sata_inic162x and sata_sx4. As libata now always prefers hardreset, this doesn't really matter but the ops are forced to NULL using ATA_OP_NULL for documentation purpose. * pata_hpt374 needs to use different prereset for the first and second PCI functions. This used to be done by branching from hpt374_error_handler(). The proper way to do this is to use separate ops and port_info tables for each function. Converted.
