* Supported types:
|
82 |
*
|
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')
