Hi there. I played around with the newer commits of the upstream QEMU version, but they have changed quite a bit with the tcg module (tiny code generator) and added a lot of flags to gcc, such that warnings are treated as errors and such. With the tcg for ARM being full of warnings it was too much a hassle to make it compile, so I eventually gave up and sticked with the version we have. However, by adding a single line to kvm-all.c in QEMU the KVMARM_NOT_IMPLEMENTED macro now exits cleanly from the kernel back to QEMU and makes QEMU shut down the VM cleanly. It makes for a nice way to trace through the workings of our code. RIght now it depends on a long path of return values, which I intent to change next time I'm on a bus or plane or something... A problem that I have to look at before going further with the memory stuff is that the way I pre-allcoate memory doesn't cause the memory to be freed even when the process is killed - taking some 80 MB of memory on each run of ./qemu-system-arm :) Of course, we can re-boot the emulator, but... Finally, the thing about swapping, apparently it's not a problem. ARM linux doesn't seem to implement swapping at all so lets not worry about it for now.
