porting info

porting info

[Dominik Táborský]

Hi,

I am considering porting Grub2 to HelenOS system, which does not prefer any standard API and instead has its own.

On the IRC channel a guy told me I need to port just grub-probe and grub-setup (please correct me if wrong). I am looking for some information, overview or something that would help me understand how things work inside GRUB2.

Primarily I'd like to know what should be ported (files and stuff) and a bit of guidance (like "don't try to fix that [...]").

Any help would be much appreciated.

Thanks in advance

Dominik

If it has a minimum of POSIX compatibility (mainly ability to run shell)
then probably the needed changes are limited to getroot.c and
hostdisk.c. Some additional features may need more changes.

Basically just try to compile it and see how it fails.

BTW I've just checked. GRUB2 is able to load HelenOS just fine (I used
legacy_configfile). So porting is limited to compiling it under HelenOS.
bdsh is obviously not enough to hold our build system or scripts. For
the required dependencies see INSTALL. In case of more questions you can
ask here.

Yes, I know :-) But thanks for caring :-)
PCC and binutils have already been ported, so I was advised to check them out, how has it been done. But I haven't had time, yet...

Thanks a lot for this one...
