Resolves #216 | |||||
2021-03-29 | pk: remove vestigial trapframe_t::insn field | Andrew Waterman | 1 | -7/+0 | |
This assumes that stval is populated with the opcode on illegal instruction exceptions. But since we're only using the opcode for error reporting, it's OK if this assumption is violated. | |||||
2021-03-25 | pk: support >2 GiB of user memory for RV64 | Andrew Waterman | 1 | -1/+3 | |
Previously, the pk would always run from virtual address MEM_START. Instead, remap it into the negative virtual addresses, allowing user processes to expand beyond MEM_START. | |||||
