From afb05b05939c4459eb10fdd51d0ba8148cea217d Mon Sep 17 00:00:00 2001 From: Mike Petersen Date: Fri, 15 Sep 2023 13:30:46 -0500 Subject: [PATCH] linux-nilrt-nohz: Downgrade to 5.15 kernel Some NI driver teams have noticed increased jitter on the 6.1 NO_HZ kernel, which has not yet been addressed. Since this issue was not present in the 5.15 kernel, we can downgrade this recipe to 5.15 to avoid performance regressions in the 2023Q4 release.
