Drivers
-------
The OHCI-1394 drivers in drivers/firewire and drivers/ieee1394 initialize
the OHCI-1394 controllers to a working state and can be used to enable
physical DMA. By default you only have to load the driver, and physical
DMA access will be granted to all remote nodes, but it can be turned off
when using the ohci1394 driver.
The ohci1394 driver in drivers/ieee1394 initializes the OHCI-1394 controllers
to a working state and enables physical DMA by default for all remote nodes.
This can be turned off by ohci1394's module parameter phys_dma=0.
Because these drivers depend on the PCI enumeration to be completed, an
initialization routine which can runs pretty early (long before console_init(),
The alternative firewire-ohci driver in drivers/firewire uses filtered physical
DMA, hence is not yet suitable for remote debugging.
Because ohci1394 depends on the PCI enumeration to be completed, an
initialization routine which runs pretty early (long before console_init()
which makes the printk buffer appear on the console can be called) was written.
To activate it, enable CONFIG_PROVIDE_OHCI1394_DMA_INIT (Kernel hacking menu:

is largely pointless as without a lot of work only the most
trivial of Solaris binaries can work with the emulation code.

---------------------------
What: init_mm export
When: 2.6.26
Why: Not used in-tree. The current out-of-tree users used it to
work around problems in the CPA code which should be resolved
by now. One usecase was described to provide verification code
of the CPA operation. That's a good idea in general, but such
code / infrastructure should be in the kernel and not in some
out-of-tree driver.

IDE ATAPI streaming tape driver
-------------------------------
This driver is a part of the Linux ide driver and works in co-operation
with linux/drivers/block/ide.c.
The driver, in co-operation with ide.c, basically traverses the
request-list for the block device interface. The character device
interface, on the other hand, creates new requests, adds them
to the request-list of the block device, and waits for their completion.
Pipelined operation mode is now supported on both reads and writes.
The block device major and minor numbers are determined from the
tape's relative position in the ide interfaces, as explained in ide.c.
The character device interface consists of the following devices:
ht0 major 37, minor 0 first IDE tape, rewind on close.
ht1 major 37, minor 1 second IDE tape, rewind on close.
...
nht0 major 37, minor 128 first IDE tape, no rewind on close.
nht1 major 37, minor 129 second IDE tape, no rewind on close.
...
Run /dev/MAKEDEV to create the above entries.
The general magnetic tape commands compatible interface, as defined by
include/linux/mtio.h, is accessible through the character device.
General ide driver configuration options, such as the interrupt-unmask
flag, can be configured by issuing an ioctl to the block device interface,
as any other ide device.
Our own ide-tape ioctl's can be issued to either the block device or
the character device interface.
Maximal throughput with minimal bus load will usually be achieved in the
following scenario:
1. ide-tape is operating in the pipelined operation mode.
2. No buffering is performed by the user backup program.
