VIM1's wifi doesn't work after update to Linux 6.1

Hi,

After update khadas VIM1's kernel to 6.1-rc7, WIFI stop working, with
below log:

I searched linux-wireless and linux-amlogic maillist no similar issue
reported.

I applied "WIP-arm64-dts-meson-set-p212-p23x-q20x-SDIO-to-100MH.patch"
to VIM1's kernel 6.1.0-rc7, is it related?

thanks.
Ning.

Hello Ning,

That's unfortunate. Have you tried reverting commit 066ecde6d826b4
"mmc: meson-gx: add SDIO interrupt support"? I'm not saying that
reverting that patch is the correct way to fix this issue. It's one of
the few recent driver changes though, so at least it's a starting
point.

Have you tried without that patch as well?


Best regards,
Martin

I have tried revert 066ecde6d826b4, and remove SDIO-to-100MH.patch,
rebuild meson_gx_mmc and dtb, replace original, this issue still
happens.

Re: VIM1's wifi doesn't work after update to Linux 6.1

[Zhang Ning]

I find a issue in linux-wireless:
https://www.spinics.net/lists/linux-wireless/msg229742.html
same timeout, but it says brcm firmware crash.

but I don't see any firmware crash log, (I don't know whether crash log
would goto linux console)

@Nick, do you have time to try this issue in your side, and is it
possible to ask your supplier for newer firmware?

BR.
Ning.

Update: Re: VIM1's wifi doesn't work after update to Linux 6.1

[Zhang Ning]

Hi, All

In previous emails, I heard WIFI works fine.

I asked Nick for their tree for linux-6.1.
(due to their tree have some package patches, which make fail to build
deb, I picked other patches)
here is my tree: https://github.com/zhangn1985/linux-stable.git

I build it in an arm64 chroot env (faster than real arm64 board), with below commands:
```
make kvims_defconfig
make bindeb-pkg -j`nproc`
```

install to my VIM1, connect it to WIFI router and run:
```
while true; do curl www.baidu.com; done
```

it stucks after 3mins, same logs shown in previous email.

here is my brcm firmware md5:
501ca4e8307ad8e71c32f0d24369bada  brcmfmac43455-sdio.bin
d3ad92472ef030c3897062ff809a9083  brcmfmac43455-sdio.txt

BR.
Ning.

bisected: "mmc: meson-gx: add SDIO interrupt support", which is pointed
out by Martin, I don't know why I'm wrong in first try.
