Is RTL8822CE compatible with Kernel 6.1 #183

Open dannyshare opened 5 months ago

dannyshare commented 5 months ago

I have successfully run the RTL8822CE module in Linux kernel 5.4 with the driver codes in this repo. But it doesn't work in Kernel 6.1 though i have put many efforts to this issue. So, i'd like to check with you whether this RTL8822CE driver in this repo is compatible with Linux Kernel 6.1?

My usage is as below: (1) imx6 board (2) build RTL8822CE as M in kernel 6.1 menuconfig (3) Each time after the board startup, four commands will be executed insmod rtw88_core.ko insmod rtw88_pci.ko insmod rtw88_8822c.ko insmod rtw88_8822ce.ko

  1. When run insmod rtw88_8822ce.ko, in most cases, the error will show as below. (few times can work) Detail error log is attached.

    Same step (1) -(4) works very well with kernel 5.4 in same hadrware platform.

It is compatible with kernel 6.1.

If you still have this problem, report it to the linux-wireless@vger.kernel.org mailing list.
