Linuxboot from scratch

[Patrick Swayne]

I am somewhat new to this, and I would like to create a linuxboot BIOS for a system that hasn't been done before. I have looked at the various systems in the boards directory of the linuxboot git, but I can't figure out how the Makefile.board files were created, etc. I can't seem to find any info on starting from scratch.

Also, the linuxboot.org site states that the linux kernel must be built with CONFIG_EFI_BDS. I can't find anh information on this either. Any kernel source I have downloaded does not have this configuration option.

Any help would be appreciated.

Hi Patrick,

You probably should have a look to heads build environment into

https://github.com/osresearch/heads

which is able to generate a linuxboot rom image without too many issues. It does include the CONFIG_EFI_BDS patch, but I believe that we do not need it anymore as Tram has created a DXE driver which takes care to load the linuxkernel from a fv. So depending on your goal it shall be good enough.

what plateform are you using ?

HI Jean-marie,

Sorry for the delay in replying.

I can compile the heads source with the default settings just fine, but if I change the boards value in the make file to anything else, it does not compile.

The platform I want to build for is Grantley. It is similar to Winterfell,

I notice in the linuxboot source (not heads), that in the various board directories (for example, boards/winterfell), That there are some very specific things in the Makefile.board files,for example, GUID values. What I need to know is how these make files were made, and where the specifics came from. With this information, I could build a system from scratch, but I can't find any information anywhere about how these specifics were obtained.l

Thanks,

"does not compile" ==> can you get us more info? those three words can
mean lots of things
