The resource control filesystem provides only a bitmask based cpus file for assigning CPUs to a resource group. That's cumbersome with large cpumasks and non-intuitive when modifying the file from the command line. Range based cpu lists are commonly used along with bitmask based cpu files in various subsystems throughout the kernel. Add 'cpus_list' file which is CPU range based. # cd /sys/fs/resctrl/ # echo 1-10 > krava/cpus_list # cat krava/cpus_list 1-10 # cat krava/cpus 0007fe # cat cpus fffff9 # cat cpus_list 0,3-23 [ tglx: Massaged changelog and replaced "bitmask lists" by "CPU ranges" ] Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Fenghua Yu <fenghua.yu@intel.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Shaohua Li <shli@fb.com> Link: http://lkml.kernel.org/r/20170410145232.GF25354@krava Signed-off-by: Thomas Gleixner <tglx@linutronix.de> |
