On all three platforms supported by vmm, we have mostly duplicated code to manage guest physical memory regions. Deduplicate much of this code and move it into sys/dev/vmm/vmm_mem.c. To avoid exporting struct vm outside of machdep vmm.c, add a new struct vm_mem to contain the memory segment descriptors, and add a vm_mem() accessor, akin to vm_vmspace(). This way vmm_mem.c can implement its routines without needing to see the layout of struct vm. The handling of the per-VM vmspace is also duplicated but will be moved to vmm_mem.c in a follow-up patch. On amd64, move the ppt_is_mmio() check out of vm_mem_allocated() to keep the code MI, as PPT is only implemented on amd64. There are only a couple of callers, so this is not unreasonable. No functional change intended. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D48270 |
