@ -640,68 +640,6 @@ config SCSI_DMX3191D
To compile this driver as a module, choose M here: the
module will be called dmx3191d.
config SCSI_EATA
tristate "EATA ISA/EISA/PCI (DPT and generic EATA/DMA-compliant boards) support"
depends on (ISA || EISA || PCI) && SCSI && ISA_DMA_API
---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
<http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here: the
module will be called eata.
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.
config SCSI_EATA_PIO
tristate "EATA-PIO (old DPT PM2001, PM2012A) support"
depends on (ISA || EISA || PCI) && SCSI && BROKEN
---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,
available from <http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here: the
module will be called eata_pio.
config SCSI_FUTURE_DOMAIN
tristate "Future Domain 16xx SCSI/AHA-2920A support"
depends on (ISA || PCI) && SCSI
