x86/intel_rdt: Introduce "bit_usage" to display cache allocations details With cache regions now explicitly marked as "shareable" or "exclusive" we would like to communicate to the user how portions of the cache are used. Introduce "bit_usage" that indicates for each resource how portions of the cache are configured to be used. To assist the user to distinguish whether the sharing is from software or hardware we add the following annotation: 0 - currently unused X - currently available for sharing and used by software and hardware H - currently used by hardware only but available for software use S - currently used and shareable by software only E - currently used exclusively by one resource group Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: fenghua.yu@intel.com Cc: tony.luck@intel.com Cc: vikas.shivappa@linux.intel.com Cc: gavin.hindman@intel.com Cc: jithu.joseph@intel.com Cc: dave.hansen@intel.com Cc: hpa@zytor.com Link: https://lkml.kernel.org/r/105d44c40e582c2b7e2dccf0ae247e5e61137d4b.1529706536.git.reinette.chatre@intel.com
