This patch removes the old pmac ide led blink code and adds generic LED subsystem support for the LED. It maintains backward compatibility with the old BLK_DEV_IDE_PMAC_BLINK Kconfig option which now simply selects the new code and influences the default trigger.

If you say Y here, your kernel will be able to manage low cost mass
|
|
storage units such as ATA/(E)IDE and ATAPI units. The most common
|
|
cases are IDE hard drives and ATAPI CD-ROM drives.
|
|
|
|
If your system is pure SCSI and doesn't use these interfaces, you
|
|
can say N here.
|
|
|
|
Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
|
|
for mass storage units such as hard disks. It was designed by
|
|
Western Digital and Compaq Computer in 1984. It was then named
|
|
ST506. Quite a number of disks use the IDE interface.
|
|
|
|
AT Attachment (ATA) is the superset of the IDE specifications.
|
|
ST506 was also called ATA-1.
|
|
|
|
Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
|
|
ATA-3. It provides support for larger disks (up to 8.4GB by means of
|
|
the LBA standard), more disks (4 instead of 2) and for other mass
|
|
storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
|
|
ATA-4 and provides faster (and more CPU friendly) transfer modes
|
|
than previous PIO (Programmed processor Input/Output) from previous
|
|
ATA/IDE standards by means of fast DMA controllers.
|
|
|
|
ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
|
|
CD-ROM drives, similar in many respects to the SCSI protocol.
|
|
|
|
SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
|
|
designed in order to prevent data corruption and disk crash by
|
|
detecting pre hardware failure conditions (heat, access time, and
|
|
the like...). Disks built since June 1995 may follow this standard.
|
|
The kernel itself doesn't manage this; however there are quite a
|
|
number of user programs such as smart that can query the status of
|
|
SMART parameters from disk drives.

There are two drivers for Serial ATA controllers.

device driver. In order to do this, say Y here and to "SCSI support"

Say Y here if you want to include enhanced support for various IDE

interface chipsets used on motherboards and add-on cards. You can

|
then pick your particular IDE chip from among the following options.
|
|
This enhanced support may be necessary for Linux to be able to
|
|
access the 3rd/4th drives in some systems. It may also enable
|
|
setting of higher speed I/O rates to improve system performance with
|
|
these chipsets. Most of these also require special kernel boot
|
|
parameters to actually turn on the support at runtime; you can find
|

a list of these in the file <file:Documentation/ide.txt>.

There are unclear terms in ATA-4 and ATA-5 standards how certain

|
hardware (an 80c ribbon) should be detected. Different interpretations
|
|
of the standards have been released in hardware. This causes problems:
|
|
for example, a host with Ultra Mode 4 (or higher) will not run
|
|
in that mode with an 80c ribbon.

help
|
|
There are two drivers for MFM/RLL/IDE hard disks. Most people use
|
|
the newer enhanced driver, but this old one is still around for two
|
|
reasons. Some older systems have strange timing problems and seem to
|
|
work only with the old driver (which itself does not work with some
|
|
newer systems). The other reason is that the old driver is smaller,
|
|
since it lacks the enhanced functionality of the new one. This makes
|
|
it a good choice for systems with very tight memory restrictions, or
|
|
for systems with only older MFM/RLL/ESDI drives. Choosing the old
|
|
driver can save 13 KB or so of kernel memory.
|
|
|
|
If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
|
|
instead of this one. For more detailed information, read the
|
|
Disk-HOWTO, available from
|
|
<http://www.tldp.org/docs.html#howto>.
