From 7569e8dc2213ecc47024ea5edbadc8736487d926 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 17 Feb 2007 02:40:25 +0100 Subject: ide: add ide_use_fast_pio() helper (v3) * add ide_use_fast_pio() helper for use by host drivers * add DMA capability and hwif->autodma checks to ide_use_dma() - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1) [ for the IT8211/2 in SMART mode this check shouldn't be made but since in it821x_fixups() we set DMA bit explicitly: if(strstr(id->model, "Integrated Technology Express")) { /* In raid mode the ident block is slightly buggy We need to set the bits so that the IDE layer knows LBA28. LBA48 and DMA ar valid */ id->capability |= 3; /* LBA28, DMA */ we are better off using generic helper if we can ] - ide-cris driver didn't set ->autodma [ before the patch hwif->autodma was only checked in the chipset specific hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check() function so there no behavior change here ] v2: * updated patch description (thanks to Alan Cox for the feedback) v3: * updated for scc_pata driver Signed-off-by: Bartlomiej Zolnierkiewicz --- include/linux/ide.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/linux/ide.h') diff --git a/include/linux/ide.h b/include/linux/ide.h index 40b5fa2f262..9e1a8b9ce18 100644 --- a/include/linux/ide.h +++ b/include/linux/ide.h @@ -1352,6 +1352,7 @@ extern int ide_dma_enable(ide_drive_t *drive); extern char *ide_xfer_verbose(u8 xfer_rate); extern void ide_toggle_bounce(ide_drive_t *drive, int on); extern int ide_set_xfer_rate(ide_drive_t *drive, u8 rate); +int ide_use_fast_pio(ide_drive_t *); u8 ide_dump_status(ide_drive_t *, const char *, u8); -- cgit v1.2.3
