6.对齐注意 Any level of PTE may be a leaf PTE, so in addition to 4 KiB pages, Sv39 supports 2 MiB megapages and 1 GiB gigapages, each of which must be virtually and physically aligned to a boundary equal to its size. A page-fault exception is raised if the physical address is in...
a supervisor call or a timer interrupt) forces a switch to a trap handler, which usually runs in a more privileged mode. The hart will then execute the trap handler, which will eventually resume execution at or after the original trapped instruction in U-mode. Traps that increase privilege l...
