/packages/disk-label, /packages/sun-parts and /packages/misc-files

by Mark Cave-Ayland

Hi folks, Is there some kind of specification for the above packages or are we free to design the interface as we choose? The reason I ask is that the current interposition order doesn't seem to be particularly logical. At the moment, the order goes like this for a CDROM: cdrom -> deblocker -> disk-label -> (misc-files or sun-parts or pc-parts) But I think it makes more sense to do this: cdrom -> deblocker -> disk-label -> (sun-parts or pc-parts) -> misc-files The reason for suggesting a change is because by placing misc-files directly after disk-label, all partition offsets have to be bubbled back up the chain using a series of get-info words to the device. If this could be reordered, it should be possible to remove most of this logic and simply pass the read/seeks back up to the parent. Otherwise, like at the moment, there is lots of code in misc-files that has to work out whether you are accessing a file or a partition directly and act differently which can't be a good thing.

when I push the enter button...

by Programmingkid

What code starts executing when I push the enter key in an OpenBIOS session? I thought it was interpret, but it isn't.

Right, I see - the grubfs APIs aren't really designed for directory listings. Okay, I'll leave as it is at the moment. I did have a quick look at whether it would be worth re-syncing with GRUB2, but I think we'd have a licensing issue since GRUB 2 is GPLv3 whereas OpenBIOS is GPLv2.

Any debugging I should turn on to provide more information? Or is there another Solaris-type O/S I should try? That's a bug. Adding "-boot d" to command line helps getting a bit further, whereas in fact there should be no difference between that and "boot cdrom" -- Kind regards, Igor V.

ofmem_claim_phys - out of space

Well, I've followed the traffic on the list quietly for a few months, updating qemu and openbios along the way as things have developed.

Sorry, I meant I had to delete the files in obj-x86/target/kernel.

Bug report

by Programmingkid

When I make changes to the file kernel/forth.c, the changes don't take effect until I manually delete the files in the folder obj-x86/host/kernel. Any changes make to forth.c should take place immediately after compilation.
