From 5e37bdc081a980dd0d669e6387bcf15ca9666f81 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 26 Apr 2008 22:25:24 +0200 Subject: ide: add struct ide_dma_ops (take 3) Add struct ide_dma_ops and convert core code + drivers to use it. While at it: * Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods. * Drop "ide_" "infixes" from DMA methods. * au1xxx-ide.c: - use auide_dma_{test_irq,end}() directly in auide_dma_timeout() * pdc202xx_old.c: - drop "old_" "infixes" from DMA methods * siimage.c: - add siimage_dma_test_irq() helper - print SATA warning in siimage_init_one() * Remove no longer needed ->init_hwif implementations. v2: * Changes based on review from Sergei: - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/ - s/drive->hwif/hwif/ in idefloppy_pc_intr(). - fix patch description w.r.t. au1xxx-ide changes - fix au1xxx-ide build - fix naming for cmd64*_dma_ops - drop "ide_" and "old_" infixes - s/hpt3xxx_dma_ops/hpt37x_dma_ops/ - s/hpt370x_dma_ops/hpt370_dma_ops/ - use correct DMA ops for HPT302/N, HPT371/N and HPT374 - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/ v3: * Two bugs slipped in v2 (noticed by Sergei): - use correct DMA ops for HPT374 (for real this time) - handle HPT370/HPT370A properly Acked-by: Sergei Shtylyov Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/ide-taskfile.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'drivers/ide/ide-taskfile.c') diff --git a/drivers/ide/ide-taskfile.c b/drivers/ide/ide-taskfile.c index fac6835273a..9504aa54c33 100644 --- a/drivers/ide/ide-taskfile.c +++ b/drivers/ide/ide-taskfile.c @@ -135,6 +135,7 @@ ide_startstop_t do_rw_taskfile (ide_drive_t *drive, ide_task_t *task) ide_hwif_t *hwif = HWIF(drive); struct ide_taskfile *tf = &task->tf; ide_handler_t *handler = NULL; + struct ide_dma_ops *dma_ops = hwif->dma_ops; if (task->data_phase == TASKFILE_MULTI_IN || task->data_phase == TASKFILE_MULTI_OUT) { @@ -178,10 +179,10 @@ ide_startstop_t do_rw_taskfile (ide_drive_t *drive, ide_task_t *task) return ide_started; default: if (task_dma_ok(task) == 0 || drive->using_dma == 0 || - hwif->dma_setup(drive)) + dma_ops->dma_setup(drive)) return ide_stopped; - hwif->dma_exec_cmd(drive, tf->command); - hwif->dma_start(drive); + dma_ops->dma_exec_cmd(drive, tf->command); + dma_ops->dma_start(drive); return ide_started; } } -- cgit
