DOS Emulator / Limiting the CPU? - Raspberry Pi Forums
hey,
using mips checked how many cycles 1 need set emulate compaq 386 on rpi in dosbox. result 2068. however, leads 100% cpu load , reducing cycles makes of old dos games pretty slow. i'm wondering if high cpu load because of sdl, though disabled scaling stuff in dosbox already. settings guys using? read people try make opengl es on rpi working in sdl - maybe , put calculation gpu instead of cpu? way, overclocking 1 ghz not change cycles - it's still 2068 assume guides state people should use around 1000 cycles (i've seen those) wrong (or well, not wrong, they're emulating box worse compaq 386).
wondering if there's other emulator dosbox works on rpi. if remember correct pages reported arm port of dosemu, though couldn't find anywhere. tried running freedos in qemu. know cpu load of 100% wouldn't harm box i'd stay below that.
tried cpulimit limit cpu - both qemu , dosbox, doesn't seem want. here tried cgroups , give me example on how that?

dos box nice , fast on windows because emulates same processor host machine , can execute blocks of machine code natively.
unfortunately pi arm based means dos box must emulate entire intel instruction set without it's cheap tricks speed code execution.
time consuming why 486 machine behaves more underclocked 80186.
other emulator support arm qemu slow same reasons dos box, required operating system stored in image file not files.
qemu can run windows 95, xp, nt4 on pi (as demonstrated) if you're prepared wait 10 minutes them boot up.
