* ide: destroy DMA mappings after ending DMA (v2)Bartlomiej Zolnierkiewicz2009-03-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | 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).

* ide: add ->dma_clear method and remove ->dma_timeout oneBartlomiej Zolnierkiewicz2009-03-311-2/+2
| | | | | | | | | | | | | | | | | | 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. 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>
* ide-cd: fix non-SECTOR_SIZE-multiples PIO transfers for fs requestsBartlomiej Zolnierkiewicz2009-03-311-5/+0
| | | | | | | | We now support arbitrary number of bytes per-IRQ also for fs requests so remove ide_cd_check_transfer_size() and IDE_AFLAG_LIMIT_NFRAMES. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide-cd: use scatterlists for PIO transfers (fs requests)Bartlomiej Zolnierkiewicz2009-03-311-0/+4
| | | | | | | | | | | | | | | | | | | | | * 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().

| | | | | | | | | | | | | | | | * Pass number of bytes instead of sectors to ide_init_sg_cmd(). * Pass number of bytes to process to ide_pio_sector() and rename it to ide_pio_bytes(). * Rename ->nsect field to ->nbytes in struct ide_cmd and use ->nbytes, ->nleft and ->cursg_ofs to keep track of number of bytes instead of sectors.
