NAME
       hwlocality_linux - Linux-specific helpers

   Functions
       int hwloc_linux_parse_cpumap_file (FILE *file, hwloc_cpuset_t set)
       int hwloc_linux_set_tid_cpubind (hwloc_topology_t topology, pid_t tid,
           hwloc_const_cpuset_t set)
       int hwloc_linux_get_tid_cpubind (hwloc_topology_t topology, pid_t tid,
           hwloc_cpuset_t set)
       int hwloc_linux_get_tid_last_cpu_location (hwloc_topology_t topology,
           pid_t tid, hwloc_bitmap_t set)

Detailed Description
       This includes helpers for manipulating Linux kernel cpumap files, and
       hwloc equivalents of the Linux sched_setaffinity and sched_getaffinity
       system calls.

Function Documentation
   int hwloc_linux_get_tid_cpubind (hwloc_topology_t topology, pid_t tid,
       hwloc_cpuset_t set)
       Get the current binding of thread tid. The behavior is exactly the same
       as the Linux sched_getaffinity system call, but uses a hwloc cpuset.

       Note:
           This is equivalent to calling hwloc_get_proc_cpubind() with
           HWLOC_CPUBIND_THREAD as flags.

   int hwloc_linux_get_tid_last_cpu_location (hwloc_topology_t topology, pid_t
       tid, hwloc_bitmap_t set)
       Get the last physical CPU where thread tid ran.

       Note:
           This is equivalent to calling hwloc_get_proc_last_cpu_location()
           with HWLOC_CPUBIND_THREAD as flags.

   int hwloc_linux_parse_cpumap_file (FILE * file, hwloc_cpuset_t set)
       Convert a linux kernel cpumap file file into hwloc CPU set. Might be
       used when reading CPU set from sysfs attributes such as topology and
       caches for processors, or local_cpus for devices.

   int hwloc_linux_set_tid_cpubind (hwloc_topology_t topology, pid_t tid,
       hwloc_const_cpuset_t set)
       Bind a thread tid on cpus given in cpuset set. The behavior is exactly
       the same as the Linux sched_setaffinity system call, but uses a hwloc
       cpuset.

       Note:
           This is equivalent to calling hwloc_set_proc_cpubind() with
           HWLOC_CPUBIND_THREAD as flags.
