Disclaimer: i intend to integrate this seamlessly into the kernel CD driver, hence i don't need any `complete package' (i've already seen and analyzed a few of them). What i'm interested in is: . how to enable CD-DA reading on the various drives (i do know already about SCSI cmd 0xd8, and about the density code 0x82 in the mode parameter buffer header, but i don't have an exhaustive list of which vendor supports what, or whether there are more conceptually incompatible solutions), and . useful hints, like those in Charles Henrichs' package; though i think fine-tuning will have to wait until the driver framework is established (i don't think the first version will be optimal, and i do not hesitate throwing away some code after a certain learning process). I wouldn't mind leaving hooks for things like CD-I or Video CD, but they aren't the primary goal either. (Posted & mailed.
