dalao考虑屏蔽一下触摸屏吗？

[OldDream]

屏蔽之后kernel_task的占用率能进一步下降到待机时2%~3%这样，省电。。。

额，考虑到有人要用触摸屏，所以没屏蔽。

我是在 BIOS 里屏蔽了，我有空加个 README 吧。

昨晚我试了一下。。很奇怪，bios屏蔽之后kernel_task的占用率最低还是10%+

log show --last boot | grep -i i2c 给我看看

VoodooI2CHIDDevice::WCOM488E Warning: Could not get interrupt event source, using polling instead

emmmmmm 好像这就是问题所在？

是的，bios 屏蔽后还是没效么？有人反馈如果用 GPIO 的话，睡醒后会触摸屏会失效。

用这个，试一下 bios 里打开触摸屏，试试 macos 下还能不能用： SSDT-TPDX.aml.zip

我的触摸屏可能因为是 9550/9560 的，就不走 I2C

好了！屏蔽成功！kernel_task占用率也掉下来了。

@OldDream 用这个后，触摸屏还能用吗

用了这个SSDT，用200130的OC release，修改了下升级到OC 0.5.6，log show --last boot | grep -i i2c 出来这么一堆错误,BIOS没有屏蔽触屏，kernel_task的占用率最低还是10%+，要怎么搞？

VoodooI2C 2.4.3 的触摸屏闲置占用很低，不用屏蔽了。
