129be006 87 * 'S' it just appends the rest of the string (accept optional quote)
361127df
MA
88 * 'O' option string of the form NAME=VALUE,...
89 * parsed according to QemuOptsList given by its name
90 * Example: 'device:O' uses qemu_device_opts.
91 * Restriction: only lists with empty desc are supported
92 * TODO lift the restriction

96 * value is multiplied by 2^20 (think Mebibyte)
dbc0c67f 97 * 'o' octets (aka bytes)
5e00984a
KW
98 * user mode accepts an optional E, e, P, p, T, t, G, g, M, m,

104 * which divides the value by 1e3, 1e6, 1e9, respectively
9307c4c1
FB
105 * '/' optional gdb-like print format (like "/10x")
106 *
fb46660e
LC
107 * '?' optional type (for all types, except '/')
108 * '.' other form of optional type (for 'i' and 'l')
