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