Questions from the meeting:
How are ARM-specific issues such as legacy alignment problems to be
addressed?
Are alignment problems not considered bugs? It's not just that this will
break code on ARM < v7 and IIRC SPARC, but alignment issues also cause
cache line straddling which has a performance impact.
If Anaconda isn't used to do installations, what will be doing the
things Anaconda does which just installing a bunch of packages doesn't?
(I don't know what these are)
Is there any actual reason why Anaconda cannot be used? What is to stop
booting a suitable installation kernel for the target platform and
having that fetch/mount an installation rootfs that takes over, same as
it does in x86? Granted the amount of RAM is an issue, but that's just a
case of dieting the installer back to a saner size (de-lobotomizing the
text mode installer back to how it was before F11, for example).
All PA kernels must be derived from the same source rpm.
I found that if the kernel has support for the right SoC, it is simply a
case of adding a suitable SoC merge config file and plumbing it in for
the build based on a build flag. I have somewhere a
2.6.32-220.<something> kernel src.rpm that builds for both x86 and
Marvell Kirkwood, and it was reasonably straightforward to achieve (even
if it did require fixing a few bugs that were introduced by upstream
vendor patches that didn't manifest on the primary arch).
