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
