From aedea5910ce44fea79e2c517bb22e0006372156f Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 13 Oct 2007 17:47:50 +0200 Subject: ide-pmac: remove pmac_ide_do_setfeature() (take 2) Use ide_config_drive_speed() instead of pmac_ide_do_setfeature() and remove the latter, also ide-iops.c::__ide_wait_stat() could be static again. Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's ->quirk_list is always zero and ->ide_dma_host_{on,off} are nops than the only changes in behavior are: * if PIO mode is set then ->dma_off_queitly is called to disable DMA * if setting transfer mode fails ide_dump_status() is called to dump status v2: * IDE PMAC controllers allow separate PIO and DMA timings and PPC userland depends on this fact, and calls "hdparm -p" without calling "hdparm -d". Therefore to compensate for DMA being disabled by ide_config_drive_speed() for PIO modes: - add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver - add handling of the new flag to ide-io.c::do_special() Cc: Benjamin Herrenschmidt Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/ide-iops.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/ide/ide-iops.c') diff --git a/drivers/ide/ide-iops.c b/drivers/ide/ide-iops.c index f7e976c0c2f3..e5fc2e505959 100644 --- a/drivers/ide/ide-iops.c +++ b/drivers/ide/ide-iops.c @@ -483,7 +483,7 @@ EXPORT_SYMBOL(drive_is_ready); * setting a timer to wake up at half second intervals thereafter, * until timeout is achieved, before timing out. */ -int __ide_wait_stat(ide_drive_t *drive, u8 good, u8 bad, unsigned long timeout, u8 *rstat) +static int __ide_wait_stat(ide_drive_t *drive, u8 good, u8 bad, unsigned long timeout, u8 *rstat) { ide_hwif_t *hwif = drive->hwif; unsigned long flags; -- cgit v1.2.3-55-g7522
