If I add #include "pci.h" at the top of the file, change TARGET_PAGE_SIZE to 4096 (generic device code is not supposed to be target-dependent), and throw foo.o into Makefile.objs it builds here. It launches successfully with -enable-kvm and I can see the device inside a VM. My qemu.git/HEAD is 1ce9ce6a6184f0192015ba9adf1123d89cd47a7b. I only had a few minutes and couldn't test reading from BAR0, but you might want to get 32-bit reads working first before trying 64-bit. Stefan
