72 * Supported types:

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