The sym53c500_cs Driver
|
|
=======================
|
|
|
|
The sym53c500_cs driver originated as an add-on to David Hinds' pcmcia-cs
|
|
package, and was written by Tom Corner (tcorner@via.at). A rewrite was
|
|
long overdue, and the current version addresses the following concerns:
|
|
|
|
(1) extensive kernel changes between 2.4 and 2.6.
|
|
(2) deprecated PCMCIA support outside the kernel.
|
|
|
|
All the USE_BIOS code has been ripped out. It was never used, and could
|
|
not have worked anyway. The USE_DMA code is likewise gone. Many thanks
|
|
to YOKOTA Hiroshi (nsp_cs driver) and David Hinds (qlogic_cs driver) for
|
|
the code fragments I shamelessly adapted for this work. Thanks also to
|
|
Christoph Hellwig for his patient tutelage while I stumbled about.
|
|
|
|
The Symbios Logic 53c500 chip was used in the "newer" (circa 1997) version
|
|
of the New Media Bus Toaster PCMCIA SCSI controller. Presumably there are
|
|
other products using this chip, but I've never laid eyes (much less hands)
|
|
on one.
|
|
|
|
Through the years, there have been a number of downloads of the pcmcia-cs
|
|
version of this driver, and I guess it worked for those users. It worked
|
|
for Tom Corner, and it works for me. Your mileage will probably vary.
