Re: [microblaze-uclinux] Microblaze uClinux 2.6.19

[John Williams <jwilliams@xxxxxxxxxxxxxx>]

Hi David,

The bootlog below might be of interest :)

2.6.x is not sufficiently complete for us to distribute with PetaLinux, 
but I appreciate people will want to try it and hopefully start working 
on the missing bits and pieces.  I'm looking at a way to host a 
development tree so people can get hacking on it.

Some small changes are required in the userland build environment as 
well, so they'll be distributed as a patch for now.

Obvious kernel things missing or to be completed:

 - cache support
 - some low-level nastiness in entry.S to be audited and fixed
 - driver support
 - general stress testing of signal handlers, interrupts and so on
 - /proc/cpuinfo is empty, as are a few other arch-provided /proc 
virtual files

No doubt a bit moer still to be discovered.

But, it's all prorgess.

John
