通过启用config_preempt,Linux内核可以具备抢占式调度的功能,提高系统的响应速度和并发性能。 在Linux内核编译配置中,config_preempt有几种不同的选项可供选择,包括NO_HZ、FULL_PREEMPT等。其中,NO_HZ是一种用于改进系统节能性能的选项,通过消除系统空闲时的定时中断,降低系统的功耗。而FULL_PREEMPT则是一种完全抢占式...
I have been experimenting with the CONFIG_PREEMPT_RT patch for a fewmonths. Specifically kernel 2.6.20.7-rt8. http://rt.wiki.kernel.org/index.php/Main_Page I've been running into some unexpected problems, so I wanted to askthose who have some experience with this patch what they thought....
Re: CONFIG_PREEMPT_RT on Raspberry Pi Sun Jun 30, 2013 7:50 am As already emailed to tom here is my finding: I used kernel 3.8.13 from branch rpi-3.8.y and patched with 3.8.13-rt12. Used the config from 3.6.11 and selected full preempt. I got the usual dead lock on booting....
Using the v5.6.4.2 driver, the following behavior was observed when CONFIG_PREEMPT_RT was enabled for the Linux kernel supporting the RT patch. The kernel version is 5.10.186-rt91 und rt patch applyed for 5.10.186. ■operation #!/bin/sh c...
