Description Anton Arapov 2013-11-18 10:45:16 UTC

Update example.conf: (this will enable user to see the current setup by tuned sysctl values by default in tuna)

This should have the higher maximum value:
kernel.sched_wakeup_granularity_ns=1000,20000000,

These sysctls should be included:
vm.dirty_background_ratio
kernel.sched_autogroup_enabled
kernel.sched_migration_cost_ns
kernel.sem
vm.max_map_count

Comment 1 Anton Arapov 2013-11-18 10:47:23 UTC

This is not functional change, and doesn't want QE at all. It is a matter of better user experience.

Comment 2 Jenny Severance 2013-11-18 18:00:30 UTC

Can I ask why the QA Contact is set to IDM QE LIST?  This means that the proper QE group will not get notified of bugs against "tuna" ..

Comment 3 Anton Arapov 2013-11-18 19:48:39 UTC

Jenny, feel free to re-assign to the proper QE group. And, perhaps, it will make sense to notify bugzilla-owner to change the default for the "tuna" component. IDM is what it has set when you report a bug against tuna.

anton: will be that rhel7 only specific?

Comment 6 Anton Arapov 2014-02-03 12:03:13 UTC

I'd like to see this change in Fedora/upstream as well. It will make the same sense as for RHEL7.

Comment 7 Petr Oros 2014-02-04 08:38:02 UTC

upstream patch: https://git.kernel.org/cgit/utils/tuna/tuna.git/commit/?id=029deca251faeea85b1fae64d79d9ba8af7dcec4

Comment 8 Anton Arapov 2014-02-04 09:09:22 UTC

John, please include the change linked in comment 3 into rhel7's tuna.

thanks!

Comment 9 John Kacur 2014-03-12 00:57:17 UTC

Fixed in 0.11.1-6 and up

Comment 10 John Kacur 2014-03-12 15:05:14 UTC

I didn't realize this needed the blocker flag set since I already had the rhel7.0+ flag, this is ready to go, please approve so I can build

Comment 11 John Kacur 2014-03-12 15:26:03 UTC

Changing to ASSIGNED until I get approval to build with this
