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