My kernel is 4.9.88 and demo board is IMX8MQ evk and Terasic C5P, they are connected thru a M.2 to pcie adaptor. The failure was reported when calling request_irq(), and return -22, which is EINVAL. Then I digged into the kernel and found failure was happened in irq_settings_can...
经过调查发现,原始是在open设备时,request gpio中断时,内核判断该gpio是 output属性,导致request gpio irq 失败。 但是很奇怪,不知道是哪里将该gpio设置成了output属性了。我们在probe函数里是明确初始化成input属性的。dts里也没有设置。 我们想了个规避方案,就是在open函数后,request irq之前,再次设置成一次input属...
