11Description:	(RW) Configure MSC operating mode:
12
13		  - "single", for contiguous buffer mode (high-order alloc);
14		  - "multi", for multiblock mode;
15		  - "ExI", for DCI handler mode;
16		  - "debug", for debug mode;
17		  - any of the currently loaded buffer sinks.
18
19		If operating mode changes, existing buffer is deallocated,
20		provided there are no active users and tracing is not enabled,
21		otherwise the write will fail.

27Description:	(RW) Configure MSC buffer size for "single" or "multi" modes.
28
29		In single mode, this is a single number of pages, has to be
30		power of 2. In multiblock mode, this is a comma-separated list
31		of numbers of pages for each window to be allocated. Number of
32		windows is not limited.
33
34		Writing to this file deallocates existing buffer (provided
35		there are no active users and tracing is not enabled) and then
36		allocates a new one.

44		triggering a window switch for the buffer. Returns an error in any
45		other operating mode or attempts to write something other than "1".
