As I read through your emails about this pxp situation, it seems like a separate issue. When I encountered the 8s delay, it was on MTL, and apparently some firmware issue meant it was never going to work. So, I thought this was a case of it either being supported, or never being supported. Now I'm seeing from your emails that in some cases it might be supported, but just not ready yet. In that case a status which is directly tied to pxp seems valuable. (But, yuck, how did we get into this situation? :) Can you tell that pxp is in progress, but not ready yet, as a separate state from 'it will never work on this platform'? If so, maybe the status could return something like: 0: It's never going to work 1: It's ready to use 2: It's starting and should work soon I could see an argument for treating that as a case where we could still advertise protected content support, but if we try to use it we might be in for a nasty delay. Maybe Lionel would have a different opinion on whether it would be a good idea to go this route. Regarding the extensions list I was requesting, it might be easiest for the kernel if it just replies with all the extensions it knows about regardless of whether they are usable right now. -Jordan
