[OLPC-devel] you can try this

[Ronald G Minnich]

OK, I am just back from travel ...

Steve, your VSA was 70k, which busted the 64k limit. So, I have added 
support to OLPC that assumes that the VSA is NRV2B compressed. This cut 
it from 70k to 42k. You now have 20k left to consume. More desirable, in 
future, would be for us to get this down to 32k, to leave room for linux ...

anyway, I have run your VSA but still have no video.

What else do I need to get video turned on?

Is anyone out there working on the 'definitive' kernel/initrd, or should 
I be doing that after all? I don't mind, just checking.

Ollie and I are in boston next week. I'm willing and able to open up a 
'hack day' anytime after wed. so we can beat on this hardware. Any 
interest?

I am attaching the nrv2b compressed OLPC VSA. I will be committing the 
changes for handling a compressed VSA in few minutes. Be warned: you 
can't go back :-)

Steve, for binary distro of olpc vsa, I recommend you use the 
linuxbiosv2/util/nrv2b/nrv2b utility, as follows:
nrv2b e olpc_vsa.bin olpc_vsa.bin.nrv
dd if=olpc_vsa.bin.nrv of=olpc_vsa.bin.nrv.64k bs=65536 conv=sync

Also, Carl-Daniel is working on a better compression mechanism, which I 
hope we will move to very soon. This will get smaller, I think.

thanks

ron
