I have ubuntu 20.04 64bits. and have this file hmp-sss.h and code:
..... {.name = "memsave",.args_type = "val:l,size:i,filename:s",.params = "addr size file",.help = "save to disk virtual memory dump starting at 'addr' of size 'size'",.cmd = hmp_memsave,},{.name = "pmemsave",.args_type = "val:l,size:i,filename:s",.params = "addr size file",.help = "save to disk physical memory dump starting at 'addr' of size 'size'",.cmd = hmp_pmemsave,},{.name = "pmemaccess",.args_type = "path:s",.params = "path",.help = "mount guest physical memory image at 'path'",.user_print = monitor_user_noop,.cmd = do_physical_memory_access,},{.name = "boot_set",.args_type = "bootdevice:s",.params = "bootdevice",.help = "define new values for the boot device list",.cmd = hmp_boot_set,},....And the function in file monitor.c:
