---help---
|
|

This driver supports all EATA/DMA-compliant SCSI host adapters. DPT
|
|
||||||
ISA and all EISA I/O addresses are probed looking for the "EATA"
|
|
||||||
signature. The addresses of all the PCI SCSI controllers reported
|
|
||||||
by the PCI subsystem are probed as well.
|
|

You want to read the start of <file:drivers/scsi/eata.c> and the
|
|

SCSI-HOWTO, available from

config SCSI_EATA_TAGGED_QUEUE

bool "enable tagged command queueing"
|

depends on SCSI_EATA
|
|
||||||
help
|
|
||||||
This is a feature of SCSI-2 which improves performance: the host
|
|
||||||
adapter can send several SCSI commands to a device's queue even if
|
|
||||||
previous commands haven't finished yet.
|
|
||||||
This is equivalent to the "eata=tc:y" boot option.
|

|
|
||||||
config SCSI_EATA_LINKED_COMMANDS
|
|
||||||
bool "enable elevator sorting"
|
|
||||||
depends on SCSI_EATA
|
|
||||||
help
|
|
||||||
This option enables elevator sorting for all probed SCSI disks and
|
|
||||||
CD-ROMs. It definitely reduces the average seek distance when doing
|
|
||||||
random seeks, but this does not necessarily result in a noticeable
|
|
||||||
performance improvement: your mileage may vary...
|
|
||||||
This is equivalent to the "eata=lc:y" boot option.
|
|
||||||
|
|
||||||
config SCSI_EATA_MAX_TAGS
|
|
||||||
int "maximum number of queued commands"
|
|
||||||
depends on SCSI_EATA
|
|
||||||
default "16"
|
|
||||||
help
|
|
||||||
This specifies how many SCSI commands can be maximally queued for
|
|
||||||
each probed SCSI device. You should reduce the default value of 16
|
|
||||||
only if you have disks with buggy or limited tagged command support.
|
|
||||||
Minimum is 2 and maximum is 62. This value is also the window size
|
|
||||||
used by the elevator sorting option above. The effective value used
|
|
||||||
by the driver for each probed SCSI device is reported at boot time.
|
|
||||||
This is equivalent to the "eata=mq:8" boot option.

---help---
|
|

This driver supports all EATA-PIO protocol compliant SCSI Host
|
|
||||||
Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
|
|
||||||
host adapters could also use this driver but are discouraged from
|
|
||||||
doing so, since this driver only supports hard disks and lacks
|
|
||||||
numerous features. You might want to have a look at the SCSI-HOWTO,
