Being able to study the source is better than nothing, but it is a far cry from having the ability to modify it and, most importantly, publish those changes. So, to restate my question more precisely: Can we expect that Marvell will provide CPSS under a license that is compatible with the Linux kernel? If that is not possible, will Marvell at least commit to allow the publishing of drivers developed from functional specifications and other chip documentation? > Anyway, as the transition process will progress - it will be less required. Yes, but it makes it hard for smaller players to get on the ride early. >> Being able to clone github.com/Marvell-switching/prestera-firmware (or >> whatever) and build the firmware from source would go a long way to alleviate my fears at least. > I understand your concerns but at this stage - we also concerned about others that might build not reliable FW images. Totally fair. That problem should be solvable by some kind of taint concept though. Presumably you have this problem already with the existing SDK model? Customers can build things on top of CPSS that are broken in a million ways. > I also agree that at some point we should ensure most of the concerns are being addressed. > > Mickey.
