Install appropriate kernel / Processor Family for kernel configuration

el_angeliux · 2020-04-23 17:27:08

Hi to everyone

I'm about to install a new Arch kernel on my machine, As this machine is a low profile PC i need to take full advantage of it. So, when it comes to select the right kernel configuration, i doubt which one is the best. In the "Processor Family" submenu that comes after navigate "make menuconfig" i can see the next options:

Opteron-Athlon64-Hammer-K8
Intel P4 - Older Netburst based Xeon
Core 2 - newer Xeon
Intel Atom
Generic-x86-64

My lscpu output:

I already know i should not select "Opteron/Athlon64/Hammer/K8" but after that I do not know, I did navigate to https://ark.intel.com/content/www/us/en … 8-ghz.html but i get even more confused. I hope someone would know which selection is the best, because i do not feel the "( )Generic-x86-64" option it is

Thanks in advance

Hey,

Regarding the intel link you already linked it says " Code Name: Products formerly Bay Trail".
So if you google Bay Trail you might find wikipedia page about Intel Atom CPU's so that's what i'd give a try.

Furthermore in your link if you scroll down a bit it says "Processor Graphics Intel® HD Graphics for Intel Atom® Processor Z3700 Series", Another reason i'd try Intel Atom

I also found this: https://en.wikipedia.org/wiki/Silvermon … y_Trail-M)
There your Processor is listet for Bay Trail-M (a bit more accurate)

This site also contains some information which is propably pretty relevant for you

Bay Trail issues on Linux: It has been widely reported that Bay Trail cpus (and possibly their derivatives including Airmont/Braswell/Cherry Trail) experience random freezes / lock-ups on various Linux kernels. Reference linux bug report 109051 on Kernel.org Bugzilla, first reported Dec-2015. Workaround seems to be setting the linux kernel flag intel_idle.max_cstate=1, which while eliminating the system freezes/lock-ups, results in increased cpu power/battery usage by preventing the cpu from entering higher power-saving C-states. Systems running Windows-OSes apparently do not experience this lockup/freeze issues.

Greetings

Thanks to everyone,

I finally compiled and installed the appropriate kernel for my machine:

As this shows, Celeron was the right option:

Performance Events: PEBS fmt2+, 8-deep LBR, Silvermont events, 8-deep LBR, full-width counters, Intel PMU driver.

Let gcc tell you, what does the following report?

gcc -c -Q -march=native --help=target | grep march

el_angeliux wrote:

Opteron-Athlon64-Hammer-K8
Intel P4 - Older Netburst based Xeon
Core 2 - newer Xeon
Intel Atom
Generic-x86-64

You have other options as well, see: https://github.com/graysky2/kernel_gcc_patch

el_angeliux · 2020-10-27 03:36:44

The output of:

gcc -c -Q -march=native --help=target | grep march

is:

[root@acer maricela]# gcc -c -Q -march=native --help=target | grep march
  -march=                     		silvermont
  Argumentos válidos conocidos para la opción -march=:
[root@acer maricela]#

Tkanks guys for the feedback.

If you apply the patch I linked above you will get the most bang out of the silvermont option therein.
