to do uncached memory access during VM operations (which can be quite expensive on some CPUs). We currently write-back PTEs as soon as they're modified; there is some room for optimization (to write them back in larger chunks). For PTEs in the APTE space (i.e. PTEs for pmaps that describe another process's address space), PTEs must also be evicted from the cache complete (PTEs in PTE space will be evicted durint a context switch). |
