Is there a document or page that details all of the changes in how
recent Fedora Core kernels are built? I've noticed several changes, and
I want to verify I understand them all. I apologize as I've seen some
traffic, but I can't seem to find a definite answer (I'm sure I just
passed over it).
Specifically:
1. The "sourcecode" package, which is now ARCH="noarch"
Assumption:
I assume the package name change was because the ARCH has changed.
Additional Q:
Why is the "sourcecode" package not built by default when
"--target=noarch" is passed? I.e.,
%ifarch noarch
%define builddoc 1
%define buildsource 0
^^^
2. There is another variable in EXTRAVERSIONS, defaults to "root"
Assumption:
I assume this is to differentiate between UML (User Mode Linux)
kernels (so the same build system can be used)?
Additional Q:
Is this a stock kernel change? Or Red Hat only?
3. Athlon no longer a build option at all in the SPEC file
Assumption:
Are there support issues with this? Or was it another reasoning?**
Additional Q:
Is there any reason why we can't "patch back in" just the few changes
into the SPEC so one can build Athlon kernels easily with
"--target=athlon"?
[ **BTW, I'm fully aware that the i686 kernel runs fairly optimized on
Athlon. But turning off the generic support, and optimizing for K7
makes a significant difference for me in engineering applications. ]
Also, to add in Athlon support, you don't have to make it part of the
"all_x86" set. In fact, I made Athlon a separate build conditional on
its own in my own spec file (for 2.6.8-1.541) here (along with a few
other changes):
http://www.vaporwarelabs.com/files/temp/kernel-2.6.8-1.541BS.spec
And for those that want to build Athlon optimized kernels, the .config
files are here:
