81d0912d 84 * 'B' block device name
9307c4c1 85 * 's' string (accept optional quote)
361127df
MA		 86 * 'O' option string of the form NAME=VALUE,...
87 * parsed according to QemuOptsList given by its name
88 * Example: 'device:O' uses qemu_device_opts.
89 * Restriction: only lists with empty desc are supported
90 * TODO lift the restriction

FB		 91 * 'i' 32 bit integer
92 * 'l' target long (32 or 64 bit)
91162849
LC		 93 * 'M' Non-negative target long (32 or 64 bit), in user mode the
94 * value is multiplied by 2^20 (think Mebibyte)
dbc0c67f
JS		 95 * 'o' octets (aka bytes)
96 * user mode accepts an optional T, t, G, g, M, m, K, k
97 * suffix, which multiplies the value by 2^40 for
98 * suffixes T and t, 2^30 for suffixes G and g, 2^20 for
99 * M and m, 2^10 for K and k
fccfb11e
MA		 100 * 'T' double
101 * user mode accepts an optional ms, us, ns suffix,
102 * which divides the value by 1e3, 1e6, 1e9, respectively
9307c4c1
FB		 103 * '/' optional gdb-like print format (like "/10x")
104 *
fb46660e
LC		 105 * '?' optional type (for all types, except '/')
106 * '.' other form of optional type (for 'i' and 'l')
942cd1f2
MA		 107 * 'b' boolean
108 * user mode accepts "on" or "off"
fb46660e 109 * '-' optional parameter (eg. '-f')
