-/* fd_mcs.c -- Future Domain MCS 600/700 (or IBM OEM) driver
- *
- * FutureDomain MCS-600/700 v0.2 03/11/1998 by ZP Gu (zpg@castle.net)
- *
- * This driver is cloned from fdomain.* to specifically support
- * the Future Domain MCS 600/700 MCA SCSI adapters. Some PS/2s
- * also equipped with IBM Fast SCSI Adapter/A which is an OEM
- * of MCS 700.
- *
- * This driver also supports Reply SB16/SCSI card (the SCSI part).
- *
- * What makes this driver different is that this driver is MCA only
- * and it supports multiple adapters in the same system, IRQ
- * sharing, some driver statistics, and maps highest SCSI id to sda.
- * All cards are auto-detected.
- *
- * Assumptions: TMC-1800/18C50/18C30, BIOS >= 3.4
- *
- * LILO command-line options:
- * fd_mcs=<FIFO_COUNT>[,<FIFO_SIZE>]
- *

-
- NOTES ON USER DEFINABLE OPTIONS:
-
- DEBUG: This turns on the printing of various debug information.
-
- ENABLE_PARITY: This turns on SCSI parity checking. With the current
- driver, all attached devices must support SCSI parity. If none of your
- devices support parity, then you can probably get the driver to work by
- turning this option off. I have no way of testing this, however, and it
- would appear that no one ever uses this option.
-
- FIFO_COUNT: The host adapter has an 8K cache (host adapters based on the
- 18C30 chip have a 2k cache). When this many 512 byte blocks are filled by
- the SCSI device, an interrupt will be raised. Therefore, this could be as
- low as 0, or as high as 16. Note, however, that values which are too high
- or too low seem to prevent any interrupts from occurring, and thereby lock
- up the machine. I have found that 2 is a good number, but throughput may
- be increased by changing this value to values which are close to 2.
- Please let me know if you try any different values.
- [*****Now a runtime option*****]
-
- RESELECTION: This is no longer an option, since I gave up trying to
- implement it in version 4.x of this driver. It did not improve
- performance at all and made the driver unstable (because I never found one
- of the two race conditions which were introduced by the multiple
- outstanding command code). The instability seems a very high price to pay
- just so that you don't have to wait for the tape to rewind. If you want
- this feature implemented, send me patches. I'll be happy to send a copy
- of my (broken) driver to anyone who would like to see a copy.
