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

Hello Zhang,

I’ve test-booted a VIM1 using my current amlogic-6.1.y branch (based on rc8) and I don’t see an issue with WiFi:

http://ix.io/4i7M

Here’s the kernel source and defconfig:

https://github.com/chewitt/linux/commits/amlogic-6.1.y
https://github.com/chewitt/LibreELEC.tv/blob/amlogic/projects/Amlogic/linux/linux.aarch64.conf

In the LE image I have wlan0 and connman is listing services:

VIM1:~ # ifconfig

*A  CIRCOLOCO            wifi_ccb8a8b59f86_434952434f4c4f434f_managed_psk

I’ve pushed an updated VIM1 image with that kernel here:

https://chewitt.libreelec.tv/testing/LibreELEC-AMLGX.arm-10.85.0-khadas-vim.img.gz

There are a couple of patches that tweak SDIO speeds in my tree, but none of them are new.

As it looks like you have some of my patches already; perhaps bisect my full patchset against default 6.1-rc8 to see if there’s a ‘fixing’ change?

I native build kernel from debian's kernel repo: https://salsa.debian.org/kernel-team/linux/
with some Amlogic patches: https://salsa.debian.org/zhangn1985/linux/-/tree/master/debian/patches/features/arm64/meson
all follow debian's kernel config.

I'm happy to see WIFI works.

WIFI on my VIM1, it can connect to AP and get IP address.
but after a while, 1sec~5min, ssh thru wifi is stucked, timeout logs
print to uart console.

could you try to connect to AP and use wifi?

On the 6.1-rc8 image I was using it connected once, then on a reboot I had no wlan0
interface and this was logged:

[   13.789321] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout

I’ve since updated to an image using 6.1 final and got the interface back. I’m not
sure I can explain the disappearance but it’s been fine since and I’ve had a movie
playing now for ~20 mins. Normally if I’m going to see a WiFi issue things fail to
play or connect.

I occasionally see this logged, but I assume this is normal/not-harmful:

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.

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.
