icside: register second channel of version 6 PCB

2009-05-16T17:03:36Z

The second IDE channel of version 6 PCB is not being registered anymore since the commit 48c3c1072651922ed153bcf0a33ea82cf20df390 (ide: add struct ide_host (take 3)). Signed-off-by: Sergei Shtylyov Signed-off-by: Bartlomiej Zolnierkiewicz

ide: set/clear drive->waiting_for_dma flag in the core code

2009-03-31T18:15:22Z

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 Signed-off-by: Bartlomiej Zolnierkiewicz

ide: destroy DMA mappings after ending DMA (v2)

2009-03-31T18:15:20Z

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 one

2009-03-31T18:15:19Z

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 Signed-off-by: Bartlomiej Zolnierkiewicz

ide: add ->dma_timer_expiry method and remove ->dma_exec_cmd one (v2)

2009-03-27T11:46:47Z

* Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it. * Add ->dma_timer_expiry method and use it to set hwif->expiry for ATA_PROT_DMA protocol in do_rw_taskfile(). * Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts. * Move setting hwif->expiry from ide_execute_command() to its users and drop 'expiry' argument. * Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile(). * Remove ->dma_exec_cmd method and its implementations. * Unexport ide_execute_command() and ide_dma_intr(). v2: * Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap). * Fix *dma_expiry naming (suggested by Sergei Shtylyov). There should be no functional changes caused by this patch. Cc: Randy Dunlap Cc: Sergei Shtylyov Signed-off-by: Bartlomiej Zolnierkiewicz

ide: pass command to ide_map_sg()

2009-03-27T11:46:46Z

* Set IDE_TFLAG_WRITE flag and ->rq also for ATA_CMD_PACKET commands. * Pass command to ->dma_setup method and update all its implementations accordingly. * Pass command instead of request to ide_build_sglist(), *_build_dmatable() and ide_map_sg(). While at it: * Fix scc_dma_setup() documentation + use ATA_DMA_WR define. * Rename sgiioc4_build_dma_table() to sgiioc4_build_dmatable(), change return value type to 'int' and drop unused 'ddir' argument. * Do some minor cleanups in [tx4939]ide_dma_setup(). There should be no functional changes caused by this patch. Acked-by: Borislav Petkov Signed-off-by: Bartlomiej Zolnierkiewicz

ide: move command related fields from ide_hwif_t to struct ide_cmd

2009-03-27T11:46:38Z

* Move command related fields from ide_hwif_t to struct ide_cmd. * Make ide_init_sg_cmd() take command and sectors number as arguments. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz

ide: call ide_build_sglist() prior to ->dma_setup (v2)

2009-03-27T11:46:37Z

* Re-map sg table if needed in ide_build_sglist(). * Move ide_build_sglist() call from ->dma_setup to its users. * Un-export ide_build_sglist(). v2: * Build fix for CONFIG_BLK_DEV_IDEDMA=n (noticed by Randy Dunlap). There should be no functional changes caused by this patch. Cc: Randy Dunlap Signed-off-by: Bartlomiej Zolnierkiewicz

icside: icside_dma_setup() fixes

2009-03-27T11:46:32Z

Check for ide_build_sglist() return value and re-map sg table if necessary. Signed-off-by: Bartlomiej Zolnierkiewicz

icside: use struct ide_port_info also for PCB version 5 (v2)

2009-03-27T11:46:17Z

This fixes hwif->channel and drive->dn assignments. v2: Fix v5/v6 mismatch noticed by Russell. Cc: Russell King Signed-off-by: Bartlomiej Zolnierkiewicz
