ZRAM support for ARM versions #8901

Open ksokolowski opened 1 year ago

ksokolowski commented 1 year ago

Hello.

I'm playing around with Batocera on my Powkiddy A12 and it works nicely for many older systems. I use it mainly with MAME mostly fine. However, the RAM on Powkiddy and on other ARM SBCs is quite often very limited. There are 4 CPU cores so I hoped that I can somehow configure ZRAM to compress RAM. This would allow to run more games that are currently stutter - most probably swapping to sdcard. Unfortunately, there is not ZRAM support in Batocera at all. Do you think that you could enable it by default for ARM ports?

can you give me an example of game that currently doesnt work and that would work with zram ? with swap enable, games are well working now i see.

There are problems with Scummvm games e.g. Blade Runner or for Arcade titles e.g. Mortal Kombat 3. Perhaps I could get better sdcard, but there is swapping visible. [root@BATOCERA /userdata/system]# free total used free shared buff/cache available Mem: 234560 183812 11108 7988 39640 34692 Swap: 524284 90228 434056

I would prefer to avoid swapping to sdcard to keep it healthy as long as possible. This is why I was hoping that ZRAM could be enabled on Batocera.
