2014-08-07Fixed README to match the riscv-tools build script install location.Christopher Celio1-1/+1
2014-08-06readmeYunsup Lee2-37/+20
2014-06-25Let timer interrupt stay set on pk start (IP[7]).Christopher Celio1-3/+0
Otherwise, the HW will trip the timer interrupt 4B cycles later and thus not match spike.
2014-06-13Changes to allow spike & RTL behavior to better match each other.Christopher Celio4-3/+10
- EI turned off on sys_exit. - IM/IP cleared on start. - badvaddr only saved to tf on page faults.
2014-06-12Handle options before vm_init is calledAndrew Waterman1-15/+29
This prevents ptbr etc. from being accessed when -p is passed.
