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

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

96 * 'i' 32 bit integer
97 * 'l' target long (32 or 64 bit)
98 * 'M' Non-negative target long (32 or 64 bit), in user mode the
99 * value is multiplied by 2^20 (think Mebibyte)
100 * 'o' octets (aka bytes)
101 * user mode accepts an optional E, e, P, p, T, t, G, g, M, m,
102 * K, k suffix, which multiplies the value by 2^60 for suffixes E
103 * and e, 2^50 for suffixes P and p, 2^40 for suffixes T and t,
104 * 2^30 for suffixes G and g, 2^20 for M and m, 2^10 for K and k
105 * 'T' double
106 * user mode accepts an optional ms, us, ns suffix,
107 * which divides the value by 1e3, 1e6, 1e9, respectively
108 * '/' optional gdb-like print format (like "/10x")
109 *
110 * '?' optional type (for all types, except '/')
111 * '.' other form of optional type (for 'i' and 'l')
112 * 'b' boolean
113 * user mode accepts "on" or "off"
