| Summary | 0001239: kernel-ml do not have CONFIG_PSI enabled | ||||
| Description | Could we have CONFIG_PSI enabled on kernel-ml builds, modern cgroupv2 is able to expose pressure stall information about cpu/memory/io which allow applications on userland to the do load shedding based on it. Also tools like below from facebook rely on it to get more information about what the system is doing. https://github.com/facebookincubator/below https://facebookmicrosites.github.io/cgroup2/docs/pressure-metrics.html | ||||

Acknowledged. |

After further checking, I see that the options CONFIG_PSI_DEFAULT_DISABLED=y and CONFIG_PSI=y are currently set for kernel-lt & kernel-ml, for el7. They are currently _not_ set for kernel-lt & kernel-ml, for el8. Hence there is a configuration regression, when migrating from el7 to el8, which need to be addressed. Hence I have now queued the addition of both configuration options for the next builds of kernel-lt & kernel-ml, for el8. |

How often do you build new kernels, so when I can know when to try again ? |
|
|
Upstream (kernel.org) release new code regularly - sometimes twice a week - and we then build the relevant kernel package set. Please review the Users' Mailing list archive [1]. It might be worthwhile for you to subscribe to that list. [2] [1] https://lists.elrepo.org/pipermail/elrepo/ [2] https://lists.elrepo.org/mailman/listinfo/elrepo/ |

With the release of the kernel-lt-5.4.201-1.el8.elrepo [1] and the kernel-ml-5.18.7-1.el8.elrepo [2] package sets this request has been fulfilled. Now closing as "resolved/fixed".
