Supported CPUs'

2014-01-21 Thread Frank Murphy
Had a choice between here or kernel@

Apologies if it somewhere,
more grey hair  less grey matter.

Does test@ fedora give a heads up,
when cpus are no longer supported.
eg kernel-3-15* will no longer support 
AMD AM2, Intel whatever

Mister Google hasn't really returned specific info.
Q: fedora no longer supported cpu's
This was the closes result: 
https://fedoraproject.org/wiki/Features/F12X86Support

The kernel community decides that so check kernel@ for their SOP in that 
regard.

No I have some older gear,
I don't like binning working kit.

Generally there has been some notice. There was a significant discussion 
when we stopped building 586 kernels and what options were used for 686 
builds.


I don't think we had an announcement here when upstream dropped 386 
support, but we weren't doing builds for those CPUs in Fedora for a 
long time before that change happened.


There have also been some CPU relevant changes in software graphics 
support used as a fallback in gnome. Not all 686 machines support 
the exact same instruction set and I saw some issues on an AMD CPU 
(an Athlon MP). However, with CPUs that old, the software graphics 
fallback for gnome is not very usable and you'll want to use another 
desktop.


Probably the next change to kernels to look for, would be the end of 
non-PAE kernel builds. I haven't heard any serious discussions about 
doing this, but that will affect some machines. I have a laptop that 
can't run PAE kernels (with a Pentium M CPU).

Just don't take too seriously what's written on 'fedora/wiki'. ;)

Bruno, are you serious? :)

Yes.

Gnome shell is not usable (for my defintion of usable, others may be 
more tolerant) using the llvm softpipe software driver fallback on 
a pair of Athlon MP CPUs.

Good, cause a whole stuff about softpipe is so bloody lame!
