68 * 'O' option string of the form NAME=VALUE,...

70 * Example: 'device:O' uses qemu_device_opts.

76 * multiplied by 2^20 (think Mebibyte)
78 * user mode accepts an optional G, g, M, m, K, k suffix,
79 * which multiplies the value by 2^30 for suffixes G and
80 * g, 2^20 for M and m, 2^10 for K and k
82 * user mode accepts an optional ms, us, ns suffix,
83 * which divides the value by 1e3, 1e6, 1e9, respectively
84 * '/' optional gdb-like print format (like "/10x")
86 * '?' optional type (for all types, except '/')
87 * '.' other form of optional type (for 'i' and 'l')
89 * user mode accepts "on" or "off"
