CSR registers is import system control registers, it had better dump all CSR registers when VM is running in system mode. Here is dump output example of CSR registers: CSR000: CRMD b4 PRMD 4 EUEN 0 MISC 0 CSR004: ECFG 71c1c ESTAT 0 ERA 9000000002c31300 BADV 12022c0e0 CSR008: BADI 2b0000 CSR012: EENTRY 90000000046b0000 CSR016: TLBIDX ffffffff8e000228 TLBEHI 120228000 TLBELO0 400000016f19001f TLBELO1 400000016f1a401f CSR024: ASID a0004 PGDL 90000001016f0000 PGDH 9000000004680000 PGD 0 CSR028: PWCL 5e56e PWCH 2e4 STLBPS e RVACFG 0 CSR032: CPUID 0 PRCFG1 72f8 PRCFG2 3ffff000 PRCFG3 8073f2 CSR048: SAVE0 0 SAVE1 af9c SAVE2 12010d6a8 SAVE3 8300000 CSR052: SAVE4 0 SAVE5 0 SAVE6 0 SAVE7 0 CSR064: TID 0 TCFG 8f0ca15 TVAL 4cefd8b CNTC fffffffffe688aaa CSR068: TICLR 0 CSR096: LLBCTL 1 CSR136: TLBRENTRY 46ba000 TLBRBADV ffff8000130d81e2 TLBRERA 9000000003585cb8 TLBRSAVE ffff8000130d81e0 CSR140: TLBRELO0 1fe00043 TLBRELO1 40 TLBREHI ffff8000130d800e TLBRPRMD 0 CSR384: DMW0 8000000000000001 DMW1 9000000000000011 DMW2 0 DMW3 0 Signed-off-by: Bibo Mao <maobibo@loongson.cn>
