ide: remove obsoleted "idex=base[,ctl[,irq]]" kernel parameters (take 2)
* Remove obsoleted "idex=base[,ctl[,irq]]" kernel parameters and update Documentation/ide/ide.txt. * Remove no longer needed ide_forced chipset type. v2: * is_chipset_set[] -> is_chipset_set in ide.c. * Documentation/ide/ide.txt fix. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

@ -71,29 +71,6 @@ This driver automatically probes for most IDE interfaces (including all PCI
|
|||
ones), for the drives/geometries attached to those interfaces, and for the IRQ
|
||||
lines being used by the interfaces (normally 14, 15 for ide0/ide1).
|
||||
|
||||
For special cases, interfaces may be specified using kernel "command line"
|
||||
options. For example,
|
||||
|
||||
ide3=0x168,0x36e,10 /* ioports 0x168-0x16f,0x36e, irq 10 */
|
||||
|
||||
Normally the irq number need not be specified, as ide.c will probe for it:
|
||||
|
||||
ide3=0x168,0x36e /* ioports 0x168-0x16f,0x36e */
|
||||
|
||||
The standard port, and irq values are these:
|
||||
|
||||
ide0=0x1f0,0x3f6,14
|
||||
ide1=0x170,0x376,15
|
||||
ide2=0x1e8,0x3ee,11
|
||||
ide3=0x168,0x36e,10
|
||||
|
||||
Note that the first parameter reserves 8 contiguous ioports, whereas the
|
||||
second value denotes a single ioport. If in doubt, do a 'cat /proc/ioports'.
|
||||
|
||||
In all probability the device uses these ports and IRQs if it is attached
|
||||
to the appropriate ide channel. Pass the parameter for the correct ide
|
||||
channel to the kernel, as explained above.
|
||||
|
||||
Any number of interfaces may share a single IRQ if necessary, at a slight
|
||||
performance penalty, whether on separate cards or a single VLB card.
|
||||
The IDE driver automatically detects and handles this. However, this may

driver using the "options=" keyword to insmod, while replacing any ',' with
