ath10k driver problems with Mikrotik R11e-5HacT

Autonomous Machines Jetson & Embedded Systems Jetson TX2
1

Hi,

I have a Jetson tx2 (JetPack 3.3.1, L4T28.3.1, kernel 4.4.159-tegra) with a custom carrier board and I am having problems getting the ath10k driver to work reliably - sometimes it works.

The card (MikroTik Routers and Wireless - Products: R11e-5HacT) uses QCA9880 which is well supported with ath10k.

I have tried disabling the SMMU (verified that it is actually disabled, no smmu errors shown) but that didn’t seem to fix anything.

Also when it actually loads and doing a soft-reboot (sudo reboot) the cpu will get stuck and the watchdog will say there is a cpu stall for 22s.

It seems to be similar to this:
https://devtalk.nvidia.com/default/topic/1032074/jetson-tx1/ath10k-driver-failing-with-wireless-pcie-card-on-tx1/

I think there is a general problem with PCIe drivers and the way the Jetson DMA/SMMU is configured.

Some information

Using latest firmware (firmware-5.bin_10.2.4-1.0-00047) from kvalo’s ath10k repo: https://github.com/kvalo/ath10k-firmware

Can you please try with the latest Jetpack release?
Also, the driver being used here is an upstreamed driver or a custom-built one? If it is a custom-built one, can you please also try with the upstream (i.e. that comes with the kernel source code) driver?

Hi vidyas,

I will try to run it with the latest JetPack (need to check that my dtb still works) but from what I see in the forum the issue wasn’t fixed in the latest jetpack - do you believe there is a fix in the latest JetPack?

Regarding the driver, I am using the driver from the kernel sources published by nvidia in l4t28.3.1, I tried to use a newer driver via backports and saw the same issue.

Hi vidays,

Seems like in JetPack 4.3 not only that it works but ath10k is compiled in the default kernel :)

The only issue that I have now is that after soft-reboot (sudo reboot) the card is not detected, i.e. lspci returns empty.

If i restart the Jetson using its RESET pin then it comes back but I think this might be because I use a non-standard pin for the reset pin of the Jetson.

One issue that now I see from time to time (seems to be from the nvidia pcie port device):

Can you please give the full output of ‘sudo lspci -vv’ ??
I’m wondering if it has ASPM states enabled. Also, try executing the below command as sudo and see if that makes any difference
echo performance > /sys/module/pcie_aspm/parameters/policy

Regarding ASPM it seems to be in powersave, am I correct:

nvidia@nvidia-desktop:~$ cat /sys/module/pcie_aspm/parameters/policy
default performance [powersave]

lspci:
