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