92 * 'S' it just appends the rest of the string (accept optional quote)
93 * 'O' option string of the form NAME=VALUE,...
94 * parsed according to QemuOptsList given by its name
95 * Example: 'device:O' uses qemu_device_opts.
96 * Restriction: only lists with empty desc are supported

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