67 * Supported types:
68 *
69 * 'F' filename
70 * 'B' block device name
71 * 's' string (accept optional quote)
72 * 'O' option string of the form NAME=VALUE,...
73 * parsed according to QemuOptsList given by its name
74 * Example: 'device:O' uses qemu_device_opts.
75 * Restriction: only lists with empty desc are supported
76 * TODO lift the restriction
77 * 'i' 32 bit integer
78 * 'l' target long (32 or 64 bit)
79 * 'M' just like 'l', except in user mode the value is
80 * multiplied by 2^20 (think Mebibyte)
81 * 'o' octets (aka bytes)
82 * user mode accepts an optional T, t, G, g, M, m, K, k
83 * suffix, which multiplies the value by 2^40 for
84 * suffixes T and t, 2^30 for suffixes G and g, 2^20 for
85 * M and m, 2^10 for K and k
86 * 'T' double
87 * user mode accepts an optional ms, us, ns suffix,
88 * which divides the value by 1e3, 1e6, 1e9, respectively
89 * '/' optional gdb-like print format (like "/10x")
90 *
91 * '?' optional type (for all types, except '/')
92 * '.' other form of optional type (for 'i' and 'l')
93 * 'b' boolean
94 * user mode accepts "on" or "off"
95 * '-' optional parameter (eg. '-f')
