CONFIG_DEBUG_PREEMPT was accidentally enabled on jammy last year as part of 5.15.0-1040.45 and was also copied into the noble realtime kernel. This should be disabled on both jammy and noble since it can introduce additional latency. |
SRU Justification:
[Impact]
CONFIG_DEBUG_PREEMPT was accidentally enabled on jammy last year as part of 5.15.0-1040.45 when we migrated to annotations for kernel configs. It was also copied into the noble realtime kernel. This config can introduce additional latency. More info on this config is at https://cateee.net/lkddb/web-lkddb/DEBUG_PREEMPT.html
[Fix]
CONFIG_DEBUG_PREEMPT should be disabled on both jammy and noble.
[Test Plan]
We will use our kernel regression testing to confirm this doesn't cause any regressions.
[Where problems could occur]
This change is limited. If code elsewhere inadvertently depends on this additional latency, it could cause a problem. |
