Re: FILO 0.4 [PMX:#]

[Greg Watson]

Correct. I haven't included linux_load, though it would probably be 
easy to do. FILO simply calls elfboot to load the image from a 
filesystem.

Merging FILO with etherboot is a fine idea, but it doesn't solve the 
loader problem for PPC. At this point I don't see any requirement to 
port etherboot to PPC, but if anyone would like to take it on then feel 
free. :-)

I think the case for including a simple FILO-like loader in linuxbios 
is a strong one. Apart from instant PPC loader support and reducing the 
difficulty of deploying linuxbios, it's possible to make use of much of 
the existing linuxbios code which significantly reduces duplication and 
complexity in the payload.

Eric,

Greg just move the fs support from filo to linuxbios, and create 
fs_stream.

It still calls the elfboot to load the elfimage in HD. And it doesn't
support linux_load.
So it is some kind of boot loader you said.

It is really enhancement to ide_stream.c

Yeah sorry, I kind of did that by stealth. Ron and I get lots of 
requests
from
people wanting to use LB but who don't know how to deal with the 
payload
issue. We decided that it would be really nice to have a simple 
bootloader
that
understands some basic filesystems built into LB. That way people can 
get
going
without having to deal with etherboot or FILO directly. A nice side 
effect
is
that it simplifies the FILO code significantly - in fact the only code
that is
really required is the filesystem support. Also, another major plus is
that the
code supports PPC as well as x86. Up to now I've had no bootloaders
(etherboot
or FILO) that work on PPC.
Then we refactor and make building the bootloader part of the tree.
These things are policy engines.  We need to separate mechanism and 
policy.

As far as I can tell this level of support crosses the line.

etherboot is portable and would not be hard to get running on ppc.
