hardware details for Xiaomi Redmibook 14 II

hi guys, I wonder if there is some plan to add the drivers for this wifi card, or if I can help somehow I may need directions. I attached the hardware information using pciconf -lv. Thank you.

I have a part-done driver based on the Intel wireless work I am doing using the linuxkpi framework.

I would hope that once the Intel work is done most infrastructure is implemented and it'll be at most a few days to have rtw88 work well as well.

Currently PCI attach and firmware loading works and then it panics due to some unimplemented memory bit.  I only spent less than a day on it so far to get to this.

So yes, there is a plan.  It'll be a while however before anything real materialises.

@Bjoern Possible to get the WIP code up in a public place somewhere?

Might encourage potential contributors to play with it and get involved.

Also, will/does/might your WIP work cover RTL8821CE (bug 247495) ?

(In reply to Kubilay Kocak from comment #2)

I'll share code as soon as it makes sense for people to test something.
As I stated it does depend on other work being done/finished first.

Hi. Is there any progress on the driver?
Comment 5 Daniel Pérez 2021-06-14 10:23:13 UTC
I am also looking forward to progress on this driver.

Please keep an eye on freebsd-wireless in the next week or so.

My computer also uses this card, hope it'll work soon :D

Hello everyone,

if you feel like giving things an early try this includes the first snapshot of the driver:


I am currently mostly AFK for the next 10 days to 2 weeks but will welcome feedback anyway and it'll help to focus once I am back.
