89 | * 's' string (accept optional quote) | |
90 | * 'S' it just appends the rest of the string (accept optional quote) | |
91 | * 'O' option string of the form NAME=VALUE,... | |
92 | * parsed according to QemuOptsList given by its name | |
93 | * Example: 'device:O' uses qemu_device_opts. | |
94 | * Restriction: only lists with empty desc are supported | |
95 | * TODO lift the restriction | |
96 | * 'i' 32 bit integer | |
97 | * 'l' target long (32 or 64 bit) | |
98 | * 'M' Non-negative target long (32 or 64 bit), in user mode the | |
99 | * value is multiplied by 2^20 (think Mebibyte) | |
100 | * 'o' octets (aka bytes) | |
101 | * user mode accepts an optional E, e, P, p, T, t, G, g, M, m, | |
102 | * K, k suffix, which multiplies the value by 2^60 for suffixes E | |
103 | * and e, 2^50 for suffixes P and p, 2^40 for suffixes T and t, | |
104 | * 2^30 for suffixes G and g, 2^20 for M and m, 2^10 for K and k | |
105 | * 'T' double | |
106 | * user mode accepts an optional ms, us, ns suffix, | |
107 | * which divides the value by 1e3, 1e6, 1e9, respectively | |
108 | * '/' optional gdb-like print format (like "/10x") | |
109 | * | |
110 | * '?' optional type (for all types, except '/') | |
111 | * '.' other form of optional type (for 'i' and 'l') | |
112 | * 'b' boolean | |
113 | * user mode accepts "on" or "off" | |
