No one should be using 4.9.y on a desktop anymore, it's over 2 years old, why would they expect any "new" hardware support to work for them? Why can't they just use 4.14.y or better yet. 4.17.y? Desktops should NOT be using a 2 year old kernel. Heck, servers shouldn't either, but that's a totally different rant. However, for hardware that is newer than the base kernel version release, I have no sympathy. Just use a newer kernel, right? What distro relies on a 4.9 kernel for brand new hardware that does not already support a newer kernel release for such hardware? > root@skl:~# uname -a > Linux skl 4.9.112+ #2 SMP Mon Jul 16 17:35:25 CST 2018 x86_64 x86_64 x86_64 > GNU/Linux > > root@skl:~# perf list | grep unc_ > unc_arb_coh_trk_requests.all > unc_arb_trk_occupancy.all > unc_arb_trk_occupancy.cycles_with_any_request > unc_arb_trk_requests.all > unc_arb_trk_requests.drd_direct > unc_arb_trk_requests.writes > unc_cbo_cache_lookup.any_es > unc_cbo_cache_lookup.any_i > unc_cbo_cache_lookup.any_m > unc_cbo_cache_lookup.any_mesi > unc_cbo_cache_lookup.read_es > unc_cbo_cache_lookup.read_i > unc_cbo_cache_lookup.read_mesi > unc_cbo_cache_lookup.write_es > unc_cbo_cache_lookup.write_m > unc_cbo_cache_lookup.write_mesi > unc_cbo_xsnp_response.hit_xcore > unc_cbo_xsnp_response.hitm_xcore > unc_cbo_xsnp_response.miss_eviction > unc_cbo_xsnp_response.miss_xcore > > root@skl:~# perf stat -a -e unc_cbo_cache_lookup.any_es sleep 1 > > Performance counter stats for 'system wide': > > 147,229 unc_cbo_cache_lookup.any_es > > 1.001204726 seconds time elapsed > > These patches are divided into 2 parts, perf core part and perf tool part. > (Please apply the patches from top to bottom in following lists, otherwise > conflicts will happen) > > 1.
