An optimization scheme for frequently stuck kernel caused by Linux RT process
After checking the kernel RT implementation, it is found that the RT process has a related occupancy time setting /proc/sys/kernel/sched_rt_runtime_us, and the default value of sched_rt_runtime_us is 950000, which means that the RT process can occupy 95% of the CPU time slice, and the remaining 5% is used for Respond to other requests, and the strange thing here is why sched_rt_runtime_us clearly set the value of 950000, why does the surfaceflinger program still use the CPU to 100%?
After code analysis and community issues search, it is found that the culprit of this problem is the RT_RUNTIME_SHARE feature, which can make RT tasks occupy 100% of the CPU for a long time, so that related kernel tasks such as kworkers cannot obtain CPU resources, resulting in kernel card die. The kernel version used by the customer happens to be version 5.4.53, in which RT_RUNTIME_SHARE is set to true by default, and the latest kernel version 5.4 has disabled this feature by default.

[[reasoning]] novel recommendation.
You can’t think well without writing well, and you can’t write well without reading well. And I mean that last “well” in both senses. You have to be good at reading, and read good things.

Clara and the Sun, to quote the translator:
All of Clara’s qualities and emotions cannot be measured by the latitude of human beings, because it is precisely because of the coexistence of selfish desires and desires for sublimation that human hearts are full of contradictions, hesitation and pain; Gravity, all the lofty and upward human nature will lose its weight in vain. Selfishness is a heavy burden for human beings, but perhaps in the not-too-distant future, it will also be one of the most important anchors for human beings.
