config_preempt是Linux内核的一个行为配置选项,主要用于控制内核的抢占式调度(preemptive scheduling)功能。在计算机系统中,抢占式调度是指操作系统能够在任意时刻中断当前任务,切换到其他任务执行的能力。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,conf...
按照默认的配置文件arch/i386/defconfig对内核进行配置,生成.config可以用作初始化配置,然后再使用make menuconfig进行定制化配置 7.make allyesconfig 尽量多地使用“y”设置内核选项值,生成的配置中包含了全部的内核特性 make allnoconfig :除必须的选项外,其它选项一律不选. (常用于嵌入式系统). 8.make allmodconfi...

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...
Hello everyone, 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 wh...
