Re: [Xbox-linux] Xbox Linux kernel for 2.6.20.1 working (sort of...)

[Ronald C.F. A. <rc...@cu...>]

OK, my quest for fairly universal, modular kernel has been reasonably  
successful.
I now have a 2.6.20.1 kernel working that has modular support for  
just about anything one might want to run on an XBOX or use the XBOX  
to do development work on.
Only actual hardware drivers have not been compiled into modules,  
because there are so many, and some seem to result in an unbootable  
kernel and if I wanted to try which, I'd still be running compile  
cycles for the next three months. Most subsystems however seem to  
work, e.g. if anyone wants to play with ATM, they can use the ATM  
over ethernet module and know the basic infrastructure is in the  
kernel. For some that's overkill, for me it's just an insurance that  
I don't have to keep dealing with the kernel itself, except if  
there's significant upgrade.

The two stumbling blocks I found are the APIC setting  
( CONFIG_X86_UP_API ) as mentioned previously. It claims to be  
harmless, but for some reason on the XBOX it is not.

The other is the fact that FATX seems to be dependent on NOT having  
CONFIG_LBD set. Interestingly enough, though, having CONFIG_LSF set  
doesn't seem to be a problem.
It seems odd, though, that a modular file system would depend on the  
system's ability to deal with large volumes. Just because that file  
system cannot address that large a volume shouldn't mean that the  
rest of the system and other file systems should not be able to do  
so. Even more curious: the FAT file system code, on which FATX is  
based, does NOT have that restriction.

So do we REALLY need that restriction of not having CONFIG_LBD set?

Otherwise, if someone tells me where I can upload the source and  
kernel rpms along with the patch and config file, then I'm pretty  
much ready to share the results if anyone is interested.
