Linux Kernel optimized configuration for emulation
Doozer:
Hi,
I am digging into the Linux latency inside the GroovyArcade (aka Arch Linux based) distribution. Why this? Because it is possible to spot hiccups (happening sporadically and not in a cyclic fashion) and I would like to trace this down. Investigations have already been performed but I am now looking at the Linux kernel configuration impact.
Would it be possible for Linux enthusiastic to provide their kernel configuration for analysis. I am looking for persons using their own kernel built with gaming/emulation optimizations.
Cheers,

I never experienced any hickups.
I've been using Lubuntu linux and the Wahcade (Mahcade) frontend from the beginning, some five years ago, always using the default kernel.
I recently switched to Linux Mint xfce, mainly because it was getting increasingly more difficult to get Daphne, the laserdisk emulator, to run on 64 bit Lubuntu.
It somehow works fine on Linux Mint 64 bit.
I tried Groovyarcade some time ago, but i prefer my own setup.

Hi General_Faliure,
Thank you for the feedback. In order to consolidate the answer, it would be kind of you if you could answer some questions.
1) Which version of mame/groovymame are you using?
2) Is your setup LCD or CRT (aka 15kHz/25kHz/31kHz) based?
3) Are you using the stock Lubuntu kernel and sysctl parameters?

Hello.
I use Mame 0.164 (Mess included), provided by Wallyweek http://sdlmame.wallyweek.org/, i just added the PPA.
I have a 19" TFT in my cab, just one i bought second hand.
I have always used the stock kernel in (L)ubuntu and now Mint 17.3 Xfce, i never changed any parameters.
I am now at my third mainboard in my cab, have a look at my pictures for the hardware i use / have used.
It's also possible to build a custom lightweight ubuntu, but i think the Xfce or Lxde based distro's are lightweight and fast enough for me.

Thank you for the shared information. I will take Lubuntu/Ubuntu reference kernel configuration inside the comparison.
