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