4*4882a593SmuzhiyunDescription:
5*4882a593Smuzhiyun		This group contains policies mandating Master/Channel allocation
6*4882a593Smuzhiyun		for software sources wishing to send trace data over an STM
7*4882a593Smuzhiyun		device.

12*4882a593SmuzhiyunDescription:
13*4882a593Smuzhiyun		This group is the root of a policy; its name is a concatenation
14*4882a593Smuzhiyun		of an stm device name to which this policy applies and an
15*4882a593Smuzhiyun		arbitrary string. If <device> part doesn't match an existing
16*4882a593Smuzhiyun		stm device, mkdir will fail with ENODEV; if that device already
17*4882a593Smuzhiyun		has a policy assigned to it, mkdir will fail with EBUSY.

22*4882a593SmuzhiyunDescription:
23*4882a593Smuzhiyun		STM device to which this policy applies, read only. Same as the
24*4882a593Smuzhiyun		<device> component of its parent directory.
25*4882a593Smuzhiyun

29*4882a593SmuzhiyunDescription:
30*4882a593Smuzhiyun		Policy node is a string identifier that software clients will
31*4882a593Smuzhiyun		use to request a master/channel to be allocated and assigned to
32*4882a593Smuzhiyun		them.

36*4882a593SmuzhiyunKernelVersion:	4.3
37*4882a593SmuzhiyunDescription:
38*4882a593Smuzhiyun		Range of masters from which to allocate for users of this node.
39*4882a593Smuzhiyun		Write two numbers: the first master and the last master number.

45*4882a593Smuzhiyun		Range of channels from which to allocate for users of this node.
46*4882a593Smuzhiyun		Write two numbers: the first channel and the last channel
47*4882a593Smuzhiyun		number.
