Details
The kboot bootloader has been broken since the clang transition, due to it Write an actual startup routine that properly calls into main() using a This also fixes the environment, which was previously broken. I verified that this makes kboot stop crashing on Playstation 3. I did not test actual loading though, as I'm not yet fully set up for doing kernel testing on my PS3 yet.

Event TimelineComment Actions Thanks! This looks basically sane. I'll try to smoke-test it in the next few days; if I don't report back by Wednesday, treat this comment as approval. Comment Actions I should also mention: one other path here is just to delete loader.kboot, since I'm not really sure it's useful. Even my PS3 loads the kernel directly from petitboot these days.

I can now successfully load the kernel. It loses when jumping to it though, I think I might need to do some entry point fixes. Comment Actions I haven't had any luck doing raw kernel loads on mine. Are you trying with ELFv1 or ELFv2 kernels? I can't get either 12.2 or -current kernels to load properly, is there some special petitboot version you are using with yours? FWIW my goal in fixing this is to readd netbooting support. I have a not-quite-working-yet net driver using linux raw sockets that is built on top of this stuff. Comment Actions BTW I got a second PS3 in the mail today so I now have the ability to test both a modern OtherOS++ (Rebug 4.86.1) setup and a classic OtherOS on OFW 2.80 setup.
