Plugin scheduler now can do cores isolation on its own, Tuna is not needed for it, e.g.: [scheduler] isolated_cores=2-4 ps_blacklist=.*pmd.*;.*PMD.*;^DPDK;.*qemu-kvm.* It will isolate cores 2-4, it will ignore processes which matched ps_blacklist regexes. Multiple regexes can be separated by ';'. Quoted semicolon, i.e. '\;' is taken literally. It also supports 'ps_whitelist' which is by default set to '.*'. It takes all processes which matches ps_whitelist than it removes those which matches ps_blacklist and move them out of the isolated_cores. When the profile is unloaded it allows all matching processes to run on all cores. It changes processes affinities, threads affinities, IRQs affinities and it sets default_smp_affinity for IRQs. Also cpu-partitioning profile has been switched from Tuna to this mechanism. Resolves: rhbz#1403309 Signed-off-by: Jaroslav Škarvada <jskarvad@redhat.com>
