This will either create a new AS or return a pointer to an already existing equivalent one, if we have already created an AS for the specified root memory region. The motivation is to reuse address spaces as much as possible. It's going to be quite common that bus masters out in device land have pointers to the same memory region for their mastering yet each will need to create its own address space. Let the memory API implement sharing for them. Aside from the perf optimisations, this should reduce the amount of redundant output on info mtree as well. Thee returned value will be malloced, but the malloc will be automatically freed when the AS runs out of refs. Backports commit f0c02d15b57da6f5463e3768aa0cfeedccf4b8f4 from qemu |
