88 * Supported types:

91 * 'B' block device name
92 * 's' string (accept optional quote)
93 * 'S' it just appends the rest of the string (accept optional quote)
94 * 'O' option string of the form NAME=VALUE,...
95 * parsed according to QemuOptsList given by its name
96 * Example: 'device:O' uses qemu_device_opts.
97 * Restriction: only lists with empty desc are supported
98 * TODO lift the restriction
99 * 'i' 32 bit integer
100 * 'l' target long (32 or 64 bit)
101 * 'M' Non-negative target long (32 or 64 bit), in user mode the
102 * value is multiplied by 2^20 (think Mebibyte)
103 * 'o' octets (aka bytes)
104 * user mode accepts an optional E, e, P, p, T, t, G, g, M, m,
105 * K, k suffix, which multiplies the value by 2^60 for suffixes E
106 * and e, 2^50 for suffixes P and p, 2^40 for suffixes T and t,
107 * 2^30 for suffixes G and g, 2^20 for M and m, 2^10 for K and k
108 * 'T' double
109 * user mode accepts an optional ms, us, ns suffix,
110 * which divides the value by 1e3, 1e6, 1e9, respectively
111 * '/' optional gdb-like print format (like "/10x")
113 * '?' optional type (for all types, except '/')
114 * '.' other form of optional type (for 'i' and 'l')
115 * 'b' boolean
116 * user mode accepts "on" or "off"
117 * '-' optional parameter (eg. '-f')
