* Supported types:
|
64 |
*
|
65 |
* 'F' filename
|
66 |
* 'B' block device name
|
67 |
* 's' string (accept optional quote)
|
68 |
* 'O' option string of the form NAME=VALUE,...
|
69 |
* parsed according to QemuOptsList given by its name
|
70 |
* Example: 'device:O' uses qemu_device_opts.
|
71 |
* Restriction: only lists with empty desc are supported
|
72 |
* TODO lift the restriction
|
73 |
* 'i' 32 bit integer
|
74 |
* 'l' target long (32 or 64 bit)
|
75 |
* 'M' just like 'l', except in user mode the value is
|
76 |
* multiplied by 2^20 (think Mebibyte)
|
77 |
* 'f' double
|
78 |
* user mode accepts an optional G, g, M, m, K, k suffix,
|
79 |
* which multiplies the value by 2^30 for suffixes G and
|
80 |
* g, 2^20 for M and m, 2^10 for K and k
|
81 |
* 'T' double
|
82 |
* user mode accepts an optional ms, us, ns suffix,
|
83 |
* which divides the value by 1e3, 1e6, 1e9, respectively
|
84 |
* '/' optional gdb-like print format (like "/10x")
|
85 |
*
|
86 |
* '?' optional type (for all types, except '/')
|
87 |
* '.' other form of optional type (for 'i' and 'l')
|
88 |
* 'b' boolean
|
89 |
* user mode accepts "on" or "off"
|
90 |
* '-' optional parameter (eg. '-f')
