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