Hi everyone, I ran the following program which simply reads the value of MiscReg (mhartid, mstatus, ...), https://pastebin.com/t5XBBWEz. (remove line 31-32)
The compilation command I used is, riscv64-unknown-elf-gcc -static hello1.c -o hello1. I ran it with SE script, gem5.opt se.py -c hello1 And this is the error I got, panic: Illegal instruction 0xf14027f3 at pc (0x101b8=>0x101bc).(0=>1): mhartid is not accessible in 0. I believe the "0" stands for the value of PrivilegeMode PRV_U right? So my question is how do I change from PRV_U to PRV_M in order to access MiscReg? Also, I have found an element of array MiscRegNames in isa.cc, which is [MISCREG_PRV] = "PRV", does this element control which PrivilegeMode that i'm in? Any help would be appreciated! Thanks Regards, Jerry
