Changes: - Provide SG_IO access to BLOCK and EXECUTIVE class on Adaptec controllers - Use PRIVATE messages in SCSI-OSM because on some controllers normal SCSI class commands like READ or READ CAPACITY cause errors - Use new DMA and SG list creation function - Added workaround to limit sectors per request for Adaptec 2400A controllers Signed-off-by: Markus Lidel <Markus.Lidel@shadowconnect.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

---help---
|
|
The Intelligent Input/Output (I2O) architecture allows hardware
|
|
drivers to be split into two parts: an operating system specific
|
|
module called the OSM and an hardware specific module called the
|
|
HDM. The OSM can talk to a whole range of HDM's, and ideally the
|
|
HDM's are not OS dependent. This allows for the same HDM driver to
|
|
be used under different operating systems if the relevant OSM is in
|
|
place. In order for this to work, you need to have an I2O interface
|
|
adapter card in your computer. This card contains a special I/O
|
|
processor (IOP), thus allowing high speeds since the CPU does not
|
|
have to deal with I/O.
|
|

If you say Y here, you will get a choice of interface adapter
|
|
drivers and OSM's with the following questions.

To compile this support as a module, choose M here: the

modules will be called i2o_core.

If unsure, say N.

raidutils to manage your RAID array, you have to say Y here.

Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM
|

provides access to the busses on the I2O controller. The main purpose

is to rescan the bus to find new devices.

help
|
|
Include support for the I2O Block OSM. The Block OSM presents disk
|
|
and other structured block devices to the operating system. If you
|
|
are using an RAID controller, you could access the array only by
|
|
the Block OSM driver. But it is possible to access the single disks
|
|
by the SCSI OSM driver, for example to monitor the disks.

To compile this support as a module, choose M here: the

Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel

you wish. To access a RAID array, you must use the Block OSM driver.
|

But you could use the SCSI OSM driver to monitor the single disks.
