The functionality was fine, at least a definite improvement. Ideally, there would have been another set of patches to top things up and really get everything running smoothly. I haven't come across any patch traffic for the card after that Novembe= r batch. In the interests of getting these amazingly cheap and effective cards running properly on Linux, it would be extremely good if someone experienced with Linux patches would get involved in the matter with Mr. Andy Yan from Marvell, straighten things out, get the ball rolling and make the driver stick in mainline. When I emailed him, Mr. Yan was very helpful and sent me the patches and some info. I tried to fix the patches myself but was in over my head. And had no time. Etc. These cards have been recommended for ZFS use on Solaris backed with solid arguments, so the hardware is definitely fine [1]. I will PERSONALLY buy two of these cards to send to any reasonably experienced Linux driver programmer willing to help finish these drivers. My company will buy two more, and I'm sure there is enough latent interest out there to get any number of development machines packed with these cards. This is the perfect case for open-source development, we just need a solid prospect that the driver issues can be nailed. -- Kristleifur [1] - http://jmlittle.blogspot.com/2008/06/recommended-disk-controllers= -for-zfs.html -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
