From 2d5eaa6dd744a641e75503232a01f52d0768884c Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 10 May 2007 00:01:08 +0200 Subject: ide: rework the code for selecting the best DMA transfer mode (v3) Depends on the "ide: fix UDMA/MWDMA/SWDMA masks" patch. * add ide_hwif_t.udma_filter hook for filtering UDMA mask (use it in alim15x3, hpt366, siimage and serverworks drivers) * add ide_max_dma_mode() for finding best DMA mode for the device (loosely based on some older libata-core.c code) * convert ide_dma_speed() users to use ide_max_dma_mode() * make ide_rate_filter() take "ide_drive_t *drive" as an argument instead of "u8 mode" and teach it to how to use UDMA mask to do filtering * use ide_rate_filter() in hpt366 driver * remove no longer needed ide_dma_speed() and *_ratemask() * unexport eighty_ninty_three() v2: * rename ->filter_udma_mask to ->udma_filter [ Suggested by Sergei Shtylyov . ] v3: * updated for scc_pata driver (fixes XFER_UDMA_6 filtering for user-space originated transfer mode change requests when 100MHz clock is used) Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/ide-iops.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'drivers/ide/ide-iops.c') diff --git a/drivers/ide/ide-iops.c b/drivers/ide/ide-iops.c index 3caa176b315..ed6128f6cd9 100644 --- a/drivers/ide/ide-iops.c +++ b/drivers/ide/ide-iops.c @@ -592,8 +592,6 @@ u8 eighty_ninty_three (ide_drive_t *drive) return 1; } -EXPORT_SYMBOL(eighty_ninty_three); - int ide_ata66_check (ide_drive_t *drive, ide_task_t *args) { if ((args->tfRegister[IDE_COMMAND_OFFSET] == WIN_SETFEATURES) && -- cgit
