Hi, This patch supports QMP dump-guest-memory in RISC-V. We tested this feature by using following command: dump-guest-memory guest.memory.
Then we used the gdb tool to debug guest.memory: gdb vmlinux guest.memory. The test result is as follow: 1. info registers ra 0xffffffe0008cb83c 0xffffffe0008cb83c <_raw_spin_lock_irqsave+28> sp 0xffffffe0012c3f70 0xffffffe0012c3f70 gp 0xffffffe0010d6048 0xffffffe0010d6048 <__compound_literal.109> tp 0xffffffe00127f200 0xffffffe00127f200 t0 0x1f8 504 t1 0x0 0 t2 0x3fd9bf5c3c 274236136508 fp 0xffffffe0012c3f80 0xffffffe0012c3f80 s1 0xffffffe0010d7228 -137421295064 a0 0x1 1 a1 0xffffffe00127f200 -137419558400 a2 0xffffffe00110a0b8 -137421086536 a3 0x3af32000 989011968 a4 0x35b2 13746 a5 0xffffffe03af6b880 -136449705856 a6 0x1c5d09af00 121820000000 a7 0x54494d45 1414090053 s2 0x1 1 s3 0xffffffe0010d73f0 -137421294608 s4 0x0 0 s5 0x0 0 s6 0x0 0 s7 0xc 12 s8 0x2000 8192 s9 0x80015708 2147571464 s10 0x0 0 s11 0x0 0 t3 0x2257d71 36011377 t4 0x0 0 t5 0x3ab0030 61538352 t6 0x3fffefb3a0 274876838816 pc 0xffffffe000201478 0xffffffe000201478 <arch_cpu_idle+10> 2. x/1024ux 0x80000000 0x80000000: 0x00050433 0x000584b3 0x00060933 0x62c000ef 0x80000010: 0x00050833 0x00040533 0x000485b3 0x00090633 0x80000020: 0x046358fd 0x1d630118 0x08171305 0x08130000 0x80000030: 0x48854868 0x0118282f 0x12081463 0x00000297 0x80000040: 0x48428293 0x00000317 0xfbc30313 0x0062b023 ...
