|
|
Sometime soon I'm upgrading my cpu to a 4790k or 4770k from a 4460.
My main boot drive is all XFS other than my kernel and grub, they're etx4
and my make.conf
Code: | CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=haswell -O2 -pipe"
CXXFLAGS="${CFLAGS}" |
I've heard that XFS doesn't work with CPUs with more or less cores. Both the 4790k and 4460 have 4, but the 4790k has 8 threads and hyperthreading
while the 4460 has only 4 cores and 4 threads. |

I don't know about the XFS core limitations, but I can tell you that you should be ok with changing out the cpu without having to recompile everything.
4790k
4460
Both of these cpus are 64bit, with the same extended instruction set.
Code: | Intel® SSE4.1, Intel® SSE4.2, Intel® AVX2 |
If you wanted to be ultra sure that everything will be ok, you can recompile everything for a generic x86_64 instruction set beforehand, and then change it back to the cpu specific set once you make the switch.
Update your /etc/portage/make.conf to use this.
Code: | -mtune=generic -march=x86-64 |
Then, recompile everything.
Then change it back once you switch out, and rebuild @world again. _________________ ---FourChannel---
