2009-03-31ide: sanitize ide_build_sglist() and ide_destroy_dmatable()Bartlomiej Zolnierkiewicz
* Move ide_map_sg() calls out from ide_build_sglist() to ide_dma_prepare(). * Pass command to ide_destroy_dmatable(). * Rename ide_build_sglist() to ide_dma_map_sg() and ide_destroy_dmatable() to ide_dma_unmap_sg(). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-31ide: set/clear drive->waiting_for_dma flag in the core codeBartlomiej Zolnierkiewicz
Set/clear drive->waiting_for_dma flag in the core code instead of in ->dma_setup and ->dma_end methods. There should be no functional changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-31ide: move ide_map_sg() call out of ->dma_setup method (take 2)Bartlomiej Zolnierkiewicz
Move ide_map_sg() call from ->dma_setup implementations and ide_destroy_dmatable() one from *_build_dmatable() to ide_dma_prepare(). There should be no functional changes caused by this patch.

2009-03-31ide: add ->dma_check methodBartlomiej Zolnierkiewicz
* Add (an optional) ->dma_check method for checking if DMA can be used for a given command and fail DMA setup in ide_dma_prepare() if necessary. * Convert alim15x3 and trm290 host drivers to use ->dma_check. * Rename ali15x3_dma_setup() to ali_dma_check() while at it.

2009-03-31trm290: use custom ->dma_{start,end} to handle trm290_prepare_drive()Bartlomiej Zolnierkiewicz
Use custom ->dma_{start,end} methods to handle trm290_prepare_drive() there instead of in ->dma_setup method.

2009-03-31ide: destroy DMA mappings after ending DMA (v2)Bartlomiej Zolnierkiewicz
Move ide_destroy_dmatable() call out from ->dma_end method to {ide_pc,cdrom_newpc,ide_dma}_intr(), ide_dma_timeout_retry() and sgiioc4_resetproc(). This causes minor/safe behavior changes w.r.t.: * cmd64x.c::cmd64{8,x}_dma_end() * cs5536.c::cs5536_dma_end() * icside.c::icside_dma_end() * it821x.c::it821x_dma_end() * scc_pata.c::__scc_dma_end() * sl82c105.c::sl82c105_dma_end() * tx4939ide.c::tx4939ide_dma_end() v2: * Fix build for CONFIG_BLK_DEV_IDEDMA=n (reported by Randy Dunlap).

2009-03-31ide: add ->dma_clear method and remove ->dma_timeout oneBartlomiej Zolnierkiewicz
All custom ->dma_timeout implementations call the generic one thus it is possible to have only an optional method for resetting DMA engine instead: * Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105 host drivers to use it. * Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove ->dma_timeout method. * Make ide_dma_timeout() static.

2009-03-31ide-cd: unify transfer padding in cdrom_newpc_intr()Bartlomiej Zolnierkiewicz
* 'thislen' is always <= cmd->nleft for non-fs requests so the transfer padding inside the 'while (thislen > 0)' loop can happen only for fs requests -- then move it out of the loop and unify with the transfer padding for non-fs requests ('thislen' == 'len' for fs requests). * blk_dump_rq_flags() dumps all request flags so it is enough to pass only the function name to it. * Update my Copyrights while at it.

2009-03-31ide-cd: use common completion path for DMA requests in cdrom_newpc_intr()Bartlomiej Zolnierkiewicz
Use the following facts: - rq->nr_sectors should now be always equal to (non-zero) rq->hard_nr_sectors for fs requests - REQ_TYPE_ATA_PC requests have never bio attached to them - rq->hard_nr_sectors == 0 for REQ_TYPE_ATA_PC requests - DMA is used only for fs, pc and REQ_TYPE_ATA_PC requests - 'uptodate' is ignored for pc requests ('rc == 0' case) and use the common completion path also for DMA requests.

2009-03-31ide-cd: use scatterlists for PIO transfers (fs requests)Bartlomiej Zolnierkiewicz
* Export ide_pio_bytes(). * Add ->last_xfer_len field to struct ide_cmd. * Add ide_cd_error_cmd() helper to ide-cd. * Convert ide-cd to use scatterlists also for PIO transfers (fs requests only for now) and get rid of partial completions (except when the error happens -- which is still subject to change later because looking at ATAPI spec it seems that the device is free to error the whole transfer with setting the Error bit only on the last transfer chunk). * Update ide_cd_{prepare_rw,restore_request,do_request}() accordingly. * Inline ide_cd_restore_request() into cdrom_start_rw().
