Indeed my primary goal is -STABLE, but the driver will not make problem in -CURRENT if it does not in -STABLE. :-) > As long as it isn't in GENERIC by default, I can't see any harm in The kernel is also not GENERIC given that it does not support 80286 anymore. ;-) > doing so (similar to what was done with Netgraph).

The SYM driver needs LOAD/STORE SCRIPTS instructions to be supported by the PCI/SCSI chip. As a result, 810 rev < 0x10, 825 rev < 0x10 and 815 all revisions support is dropped. LOAD/STORE have lots of advantages (I have detailed some in the Linux README.ncr53c8xx file and I will add those explanations also for the FreeBSD driver README file) and some may be astonishing: for example, PCI-2.2 requires pci devices that access their target part as a master to read the PCI bus signals internally. Only LOAD/STORE allow to be PCI-2.2 compliant with SYMBIOS chips, MEMORY MOVEs for accessing IO registers do not. > I'd really love to see this driver in -STABLE. I've been using 0.9.0 > since it was released and haven't had any problems. My goal was to propose the driver for inclusion when Ultra-3 support will be tested. It seems to work fine at the moment and I will make some heavy testings prior to announce it as available. The next point I have to solve is to make the ncr and the sym live in vertue rather than in sin. :) My plan is to have driver version 1.0.0 in about 2 weeks, with a better integration in the kernel than the current one (options, etc ...) and a minimal documentation.
