This feature is to design/implement a mechanism to display the precise raw event codes for the generic events in a suitable file in sysfs. Following is a posting of the small patch set to the community https://lkml.org/lkml/2016/1/11/982 == Comment: #3 - Diane Brent <[email protected]> - 2016-03-01 13:59:30 == Any new news from maintainer? When is deemed too late to try to get this in 16.04? Feature freeze is passed. Kernel freeze is 4/07. Will this target 16.04.1/16.10? == Comment: #5 - Sukadev Bhattiprolu <[email protected]> - 2016-03-23 20:44:20 == The patches were merged into mainline recently: commit d4969e2 Author: Sukadev Bhattiprolu <[email protected]> Date: Mon Jan 11 14:55:25 2016 -0800 powerpc/perf: Remove PME_ prefix for power7 events commit e0728b5 Author: Sukadev Bhattiprolu <[email protected]> Date: Mon Jan 11 14:55:26 2016 -0800 powerpc/perf: Export Power8 generic and cache events to sysfs http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/powerpc/perf/power7-pmu.c?id=d4969e2459c6e852a6862256cf8e869aaa3e8adf http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/powerpc/perf/power8-pmu.c?id=e0728b50d480da6be228dd160a43b37e4c0b1636 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1578211/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
