[Qemu-devel] IPC syscall emulation and glibc 2.3.x fix

[Derrik Pates]

I'm working on adding emulation of the ipc syscall to qemu. I've managed 
to get SHM (mostly) working - at least, to the point that some X apps 
like it alright. I've run xwf (a simple GTK+-based file manager) and I 
managed to (with a lot of debug options) get Loki's port of SimCity 3000 
started (though it hangs if you try to launch a game - it appears to get 
a SIGRTMIN and become confused by that, also the colors are obviously 
ordered wrong in the image, but the speed in the menu is pretty good). I 
intend to add support for semaphores and message queues as well, once I 
get the shmctl() stuff finished - still working on a few issues with 
getting stats on SHM segments.

Also, I've found a solution to some glibc changes that caused a build 
error on line 536 of cpu-exec.c (at least on PPC). However, to 
successfully #ifdef that so that it can still work with older glibc 
versions, I need to be able to fix the original configure.in that the 
configure script is generated from. Can that be added to CVS, so that it 
can be fixed as well?

Once I have this stuff ready (as well as possibly wrapping the _sysctl 
syscall), I'll submit a patch with all my changes.
