1 year ago There are two (types of) drivers for the RTL8821CE chip:
So the driver in the commit linked above is an alternative to rtw88. And it happens to be newer than the driver in this repo. That's why I linked to the rtw_version.h file, to show the date.
Why is the old style driver dumped into the rtw88 repo? That's something only Larry Finger knows.

1 year ago How can I choose which driver I use from rtw88? If I understand correctly, it contain two ones.

1 year ago Hi, I have experience with all 3 drivers (as a user) with a pci-e 8821ce chipset. I need to have AP + client working at the same time.
tomaspinho/rtl8821ce: stable, but sometimes the commmand "iw wlanX scan" locked forever. Didn't try if AP+client works.
lwfinger/rtw88: required configuration tweaks to make it stable (out of the box, it crashed my board sometimes even during boot time). I've tried to make AP+client work, as it should since it is based on mac80211. Author says it should work. but never been able to.
lwfinger/rtw88 "alt driver": stable, needs to be compiled with a flag to enable both wlan0 and wlan1. Configured as AP+client, it works. Still sometimes hangs during "iw wlanX scan", but worked around this using wpa_cli.

@bragma how to you build/make the driver from lwfingers rtw88/alt_rtl8821ce, you use e.g." -Wno-error=implicit-function-declaration" or such ... ? can you PLEASE clearing for me , i become errors during make, and i mean not distribution-specific-errors:
