Function Documentation

ide_init_enable()

static void ide_init_enable ( struct device *  dev )

static

Initialize the IDE controller.

Depending on the configuration variables 'ide0_enable' and 'ide1_enable' enable or disable the primary and secondary IDE interface, respectively.

Depending on the configuration variable 'ide_legacy_enable' enable or disable access to the legacy IDE ports and the PCI Bus Master IDE I/O registers (this is required for e.g. FILO).

Parameters

dev	The device to use.

ide_init_i82371ab_eb_mb()

static void ide_init_i82371ab_eb_mb ( struct device *  dev )

static

IDE init for the Intel 82371AB/EB/MB IDE controller.

Parameters

dev	The device to use.

Definition at line 124 of file ide.c.

ide_init_i82371fb_sb()

static void ide_init_i82371fb_sb ( struct device *  dev )

static

IDE init for the Intel 82371FB/SB IDE controller.

These devices do not support UDMA/33, so don't attempt to enable it.

Parameters

dev	The device to use.

Definition at line 114 of file ide.c.

Here is the call graph for this function:

ide_init_udma33()

static void ide_init_udma33 ( struct device *  dev )

static

Initialize the Ultra DMA/33 support of the IDE controller.

Depending on the configuration variables 'ide0_drive0_udma33_enable', 'ide0_drive1_udma33_enable', 'ide1_drive0_udma33_enable', and 'ide1_drive1_udma33_enable' enable or disable Ultra DMA/33 support for the respective IDE controller and drive.

Only do that if the respective controller is actually enabled, of course.

Parameters

dev	The device to use.
