Gief GREX support
The problem with GREX is that no one* knows how to program it.
I have partly reverse engineered the GREX programming interface. See
this thread on AmiBay. Unfortunately, I don't own the hardware myself and I've got to the point where it is difficult to continue without it
.
I've got memory and I/O accesses figured out, reading configuration from the PCI card too. I still don't know how to access configuration for PCI slots beyond slot 1. Also, I've never checked if interrupts work the way I suspect they work.
If anyone has information regarding GREX programming, please drop me PM. I'm the guy who wrote
this driver, and I'd gladly extend it to support GREX. It's open source, so it could be used as a reference to write AmigaOS 4 driver...
