I'm going to buy a new system to speed up lfs builds. From what I read
the new AMD Ryzen 7 1700 would be a good choice for this job. Has anyone
tested this processor on lfs?
In early May I bought a new ASUS TUF motherboard, Intel 3770 processor,
and 32G of ram. LFS builds quickly on this new system. I would think
that the new AMD processor would be similar.
Thanks. My concern is not that much on speed, various benchmarks
I've seen show it's fast enough. What I have in mind is stability
and compatibility. Segmentation faults, software produced not running
on other machines and such.
For not running on other machines, my usual answer is to blame gmp.
Except from gmp, I thought that until gcc catch up with Ryzen,
such problems would arise.
If the problem was illegal instruction, I would agree with you, but it's
hard to see how the compiler that works with Intel and other AMD
processors would case segmentation faults.
In addition, the rather long thread I read indicated that the problem was
erratic. Users would repeatedly compile mesa (or other packages) in a
loop and it would fail at random iterations. That points to HW.
My best guess that the problem is some sort of complex timing problem
between the processor and it's support chips.
