PTW, RVH: fix the bug that the last second stage translation continues after the first stage translation raises af #3096

Closed pxk27 closed 3 months ago

pxk27 commented 3 months ago
  1. ppn_af will check ppn_high because the paddrbits is 36. But when s2xlate is enabled, stage 1 ppn is 41 bits because stage 2 is sv39x4. ppn_af should not check ppn_high when s2xlate is enabled.
  2. when accessfault happens in stage 1 translation, PTW should resp rather than entering the last stage 2 translation.
