Backport to 4.14 #14

Closed jowoeber closed 4 years ago

jowoeber commented 4 years ago

Hi, thanks for your great work. I have a device running Kernel 4.14 (with upgrades not really an option ) where I would like to use this version of the ATH10K-SDIO driver (the version in Mainline 4.14 does not seem to work). I tried backporting it as described by the ATH10k drivers page but the backport Script did not work and copying the described files by hand lead to a lot of compile errors I was not able to fix correctly.

Is there some Backport to 4.14 of this driver version somewhere or maybe a backport to a driver version that is at least closer to 4.14 so backporting would be easier?

Hi, I won't give you exact howto but guidelines I used to get ath10k working on 4.14. Steps:

BR, Primoz

JohannesWoeber commented 4 years ago

Thanks. I will try that.

jowoeber commented 4 years ago

Hi, thanks for the tip. It kind of worked. I actually created the backports directly from the repo and didnt apply them to a pre packaged backport. They also seem to load fine.

But when I activate, deactivate and then reactivate the interface an error is thrown. Could this be due to the backporting?

Hi @jowoeber

looks like you're running into the same issues as I did :) Check out this issue reported by me: Issue 13 Report if it helps? BR, Primoz

Thanks. I can reenable the interface now.

You did not try to create an AP by chance as well.

This seems to be related with the fact that I cant set the Mode.

@jowoeber I did also encounter this error when I tried to enable hostapd.

Here is my patch:

Hope it helps, BR, Primoz

Hi @pfiser, Thanks again. Yes it worked. I can create an AP now.

jowoeber commented 4 years ago

Did you by chance also see the behaviour, that the AP is only maintained for a couple seconds before collapsing without a dmesg or anything. Sry for that vague description, I am trying to narrow it down currently but did you maybe see something similar?

The AP works, I can connect with other devices to it and ping in all directions but at some point it just stops. There is no error code or debug message thrown and the ifconfig command still shows the if as up but there is nothing visible when scanning with wifi analyzer.

pfiser commented 4 years ago

Hi @jowoeber, no I haven't encountered this behaviour before. But I haven't really used AP function much. I did it just for testing purposes. Our primary usecase is client mode only. Sorry, but this time you are on your own :)

Couple of hints:

jowoeber commented 4 years ago

Thanks, my luck was bound to run out at some point. Will try your tips and report back.

jowoeber commented 4 years ago

Hi, the solution to my problems seemed to be use the ath-201810230921-ath10k-high-latency-tx-bundling branch with your two patches. Thanks.

With that it was possible to create an AP without it collapsing pretty much immediatly and to transfer data over it.

Hi Joannes, I am glad you got it working. Also thanks for providing information about the solution (workaround). BR, Primoz
