Miscellaneous framework, LED framework, UIO framework, Input framework and the IIO industrial framework. This second edition has been updated to the v4.9 LTS kernel. Nettet有的led可能是接在gpio管脚上,不同的led有不同的gpio来控制; 有的led可能由其他的芯片来控制(节约cpu的pin,或者为了控制led的电流等) 可以设置亮度; 可以闪烁所以 Linux 中 led 子系统驱动框架把把所有 led 的共性给实现了,把不同的地方留给驱动工程师去做。 NettetLinux support should come from the Distro. Framework has given several Distros the tools needed for this. I can see asking for support from a specifically Linux Builder/SI, but wouldn't expect it anywhere else. That said, EndeavourOS now works perfectly on Framework for me. collections milton graham
