83 | * 'F' filename | |
84 | * 'B' block device name | |
85 | * 's' string (accept optional quote) | |
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 | |
91 | * 'i' 32 bit integer | |
92 | * 'l' target long (32 or 64 bit) | |
93 | * 'M' Non-negative target long (32 or 64 bit), in user mode the | |
94 | * value is multiplied by 2^20 (think Mebibyte) | |
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 | |
100 | * 'T' double | |
101 | * user mode accepts an optional ms, us, ns suffix, | |
102 | * which divides the value by 1e3, 1e6, 1e9, respectively | |
103 | * '/' optional gdb-like print format (like "/10x") | |
104 | * | |
105 | * '?' optional type (for all types, except '/') | |
106 | * '.' other form of optional type (for 'i' and 'l') | |
107 | * 'b' boolean | |
108 | * user mode accepts "on" or "off" | |
109 | * '-' optional parameter (eg. '-f') | |
