It seems this might be intentional? @jerpelea could you provide some context? Is msm-irqbalance working fine without rq-stats? |
|
If I remember correctly it was WIP from @kholk |
|
I see, thanks :) let's see if @kholk has time to chime in and provide some input 💪 |

Same issue on Xperia 1 either on Android 10 or 11. |
After enabling this one for Kumano it works on A10. |

This reverts commit fa80a1a. CONFIG_QCOM_RUN_QUEUE_STATS is needed for MSM-irqbalance to work. Re: sonyxperiadev/bug_tracker#760

Description
It appears the IRQ balancer is not able to find some of its dependencies.
