Info directory

--------------



The 'info' directory contains information about the enabled

resources. Each resource has its own subdirectory. The subdirectory

names reflect the resource names. Each subdirectory contains the

following files:



"num_closids":  The number of CLOSIDs which are valid for this

	        resource. The kernel uses the smallest number of

		CLOSIDs of all enabled resources as limit.



"cbm_mask":     The bitmask which is valid for this resource. This

		mask is equivalent to 100%.



"min_cbm_bits": The minimum number of consecutive bits which must be

		set when writing a mask.





Resource groups

Resource groups are represented as directories in the resctrl file
