From 7357f5665ba240aec67d5a69dc459c9ad231716d Mon Sep 17 00:00:00 2001 From: Chris Johns Date: Thu, 8 Oct 2009 07:25:15 +0000 Subject: 2009-10-08 Chris Johns * libchip/ide/ata.c, c/src/libchip/ide/ata_internal.h: Remove the multiblock support from the ATA driver. Multiblock at the disk level should not be a global policy as a disk may have more than one partition with different block sizes. An IDE driver could decide to use the feature with DMA but this a driver specific design choice. Fixed bugs relating to variable block sizes and large block transfer. * c/src/libchip/ide/ide_controller.c, c/src/libchip/ide/ide_ctrl_cfg.h, c/src/libchip/ide/ide_ctrl_io.h: Changed the block size to 32bits so blocks of 64K or bigger can be transfered in a single driver call. --- c/src/ChangeLog | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'c/src/ChangeLog') diff --git a/c/src/ChangeLog b/c/src/ChangeLog index 3f5b915c41..c0ef0734d3 100644 --- a/c/src/ChangeLog +++ b/c/src/ChangeLog @@ -1,3 +1,17 @@ +2009-10-08 Chris Johns + + * libchip/ide/ata.c, c/src/libchip/ide/ata_internal.h: Remove the + multiblock support from the ATA driver.
