Hi all,
I just now got the Moblin (2.6.29) kernel merged into the FACTORY kernel, so it should start showing up in the next few builds.
Cool. The majority of it looks like small fixes and adding the /dev stuff.
It really wasn't that many changes, the real work is in the configurations.
So, here's what I plan on doing, and it would be great to get some feedback.
For Moblin, we used a PAE kernel as "kernel-default". For FACTORY, I can't do that, and as we moved away from the -legacy to -default naming scheme, I'll change the Moblin images to use kernel-pae.
In the kernel-pae config, I'd like to start changing stuff to reflect the fastboot things we did for Moblin. In the end, we were booting the kernel in less than a second on a tiny netbook, and I see no reason why we can't do the same for FACTORY and all future releases.
To achieve this, I'll start to change the i386/pae and x86-64/default configurations to build a whole raft of drivers into the kernel, which speeds up booting a _lot_ due to the async probing that it allows the kernel to do.
I'm still not a fan of this, but in the absence of the ability to link in modules at install time, I guess the gains outweigh the drawbacks.
Why don't we do something about it?
I've already spent some thoughts about it, and come up with two possibilities:
- Link in modules during initrd run. Shouldn't be too hard, after all that's what the kernel does nowadays during building anyway. So just some linker magic and you're done. Drawback is that you'd need an uncompressed kernel to start with, so I'm not sure it's the right way to go
I thought we still have /boot/vmlinux-$VERSION.gz in each kernel package. I guess this will be kept in future, too, because it's needed for many debug tools. Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
