[WINE-CE] Wine-CE Can Run Cross Instruction Architecture Windows App

Wine-CE (Chimera Edition) is a compatibility layer capable of running Windows applications on Cross-architecture paltform of Linux. It is base on Wine Project and Qemu Project.

Hi,

I'm a co-author of https://github.com/andrerh/hangover , which had similar goals.

I haven't tried to build your code yet. Sadly gitee doesn't let me look at anything without creating an account, although I could do an actual checkout of your Wine modifications. qemu is still making its way through my slow internet conenction.

From your description it sounds like you are using Wine's under-development windows-style multilib support to run parts of Wine as arm-native code and the rest as x86. You might be interested to know that we have similar plans. The idea is to handle this the same way windows on arm handles this by having an xtajit.dll instead of wow64cpu.dll that does the emulation entry/exit at the wine fake syscall level.

André started looking into this and had some success. I don't know if he published his code yet. Upstreaming something for that goal will likely happen after Wine 8.0 is released.

The big challenge is emulation speed. Games are a somewhat special case because a lot of CPU time is spent in drivers, which remain ARM native in Wine's hybrid approach or hangover (but not if you use qemu-linux-user). qemu is terribly slow, too slow to run most applications at acceptable speed. Other than d3d and maybe sound mixing, the windows DLLs do relatively little work and all CPU time is spent in the application's code, which remains x86 code and needs to be emulated.
