The versatile board also uses an Arm926 core (as well as sharing much of the device emulation). > Is everythink platform specific implemented in ./hw/integratorcp.c ? Yes. There's actually very little board specific code. Almost everything (including interrupt controllers) are implemented as independent devices, the board specific code just instantiates those devices. > If my software works on qemu, does it work on a real Integrator board, too? > Or are there some differences? There are several bits of of hardware emulation missing (notably flash, MMC and AACI). Partly as a side-effect of this there's no significant bootloaded on the emulated board. It knows how to load linux kernels (or I guess and PIC binary image), but that's about it. Also note that qemu isn't even vaguely cycle accurate, and doesn't accurately model TLB or cache. It should be sufficient for most applications, but code that does sneaky hardware specific things (like assuming a particular TLB size or relying on cache/TLB lockdown for correct behavior) will break. Other than that it should work just like real hardware. I'm sure there are bugs if you look hard enough, but that's a somewhat different issue.
