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