触摸版只能强制轮询模式？怎么办

gf0067 · 发表于 2023-6-1 16:32

机型是联想 Flex5-15
触摸板的硬件名称是 MSFT0001
自己学着 YOGA-C940 的机型打了补丁。在中断模式下，那个触摸板非常卡顿。移动指针，一卡一卡的

这个机子和 C940 几乎一样的配置，只是这个是 15.6 寸，当然了，BIOS 有很大区别，因为 C940 是 YOGA 系列的

目前的情况是
中断模式下触摸板很卡顿，触摸屏没有反应

加入启动参数 -vi2c-force-polling 强制使用轮询模式，那么触摸屏与触控板都能正常工作

但是轮询模式吗，貌似比较消耗 CPU 资源。有没有大佬探讨下呢

我贴一下 dsl 代码
