73 * 'O' option string of the form NAME=VALUE,...
74 * parsed according to QemuOptsList given by its name
75 * Example: 'device:O' uses qemu_device_opts.
76 * Restriction: only lists with empty desc are supported
77 * TODO lift the restriction
79 * 'l' target long (32 or 64 bit)
80 * 'M' just like 'l', except in user mode the value is
81 * multiplied by 2^20 (think Mebibyte)
83 * user mode accepts an optional G, g, M, m, K, k suffix,
84 * which multiplies the value by 2^30 for suffixes G and
85 * g, 2^20 for M and m, 2^10 for K and k
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")
91 * '?' optional type (for all types, except '/')
92 * '.' other form of optional type (for 'i' and 'l')
94 * user mode accepts "on" or "off"
95 * '-' optional parameter (eg. '-f')
