We don't implement a Cortex-A7 in QEMU, because we have no board models that need it. >> b) Can we use the CPU definitions of Cortex-A15 for Cortex-A7? Typically guest code doesn't care about the exact CPU type between the A15 and the A7. If you wanted to add A7 support then starting with the A15 would be a good start. >> c) What would be the diff of Cortex-A7 definitions compared to Cortex-A15? You need to look at the Technical Reference Manual for the two CPUs to determine the difference. As far as QEMU is concerned the things to look at are: * ID register values * supported CPU features * any implementation-specific coprocessor registers ...in other words, all the things we set in the cortex_a15_initfn(). thanks -- PMM
