OK, I've committed code that turns on shadow dram in F segment, so PIRQ will work; also committed what should be working SMBUS code in vt8231_early_smbus.c; now the fun begins. I could use advice on: - what SMBUS bytes we need to care about - what we should program the north with using those bytes. - how to do it.
Which is to say, I think I know, but let's get this done in a speedy fashion. Momentum is on our side here.
The EPIA will be a good demo platform.
Why this sudden burst of EPIA work from me? Two reasons: - I want to encourage people to look at V2, so we need a demo system less complex than the K8 systems. - We are teaching a tutorial on linuxbios, bproc, etc. and will be doing it hands-on with a roomful of EPIAs, 2 or 3 per tutorial attendee. See: http://lacsi.lanl.gov/symposium/agenda.shtml Come if you want. You can see how we build clusters that boot in seconds. The software we're showing is the same stuff that is running on our 1024-node Pink cluster, and will run on our 1408-node K8 cluster.
