IOCTLs can be -converted too. +System calls are the principle interface between user-space and the +kernel. Generally the same system calls exist on all versions of the +kernel so QEMU includes a generic system call translator. The +translator takes care of adjusting endianess, 32/64 bit parameter size +and then calling the equivalent host system call. + +QEMU can also adjust device specific ``ioctl()`` calls in a similar +fashion.
