Kernel page fault after loading if_athp
bradleythughes opened this issue · comments
I'm creating this issue as advised in #freebsd-wifi on EFNet.
I have a Dell XPS 13 9370 with a Killer Wireless-AC 1435 NIC, which seems to be based on the QCA6174.
I installed a 12.0-CURRENT snapshot[1] and then built this module to see what happens. After loading the module, I get a Kernel Page Fault panic:
Reading symbols from /boot/kernel/if_athp.ko...done.

I put the full crash dump details in Gist[2].
I'll look in to this.
I got a mail notification that you were wondering if I could try again. I downloaded and install 12.0-ALPHA8 and rebuilt the module. I get the same crash as before (backtrace below, this time with debugging symbols):

Hey bradleythughes, I may have ran in to your issue myself, if you would like to checkout my local branch which is https://github.com/Geramy/athp/tree/mtx_lock_null
Give it a shot and let me know, I found a few issues and have submitted a pull request for this issue.
I hope I can get yours working as well, at least partially, we want as much test cases as we can get so that we can test and test more and more 👍
Howdy! I will give it a try later this evening. :)
Hey, sorry there has been bugs in my branch, but give my new branch a checkout and i'm going to merge it in to a single branch then do a pr soon. checkout the branch athp_parent_dma_allocate
I will give that a try. I got the same crash with your mtx_lock_null branch, but I will happily try whatever you need me to :)
Cool, let me know how that goes and submit a log for me, I been working on dma stuff maybe if effected you maybe not, i'll look in to that file tonight and work on your bug specifically if it isn't already fixed because of any change i might have done. It might just be a little hard for me because I dont have your wifi card but i'll give it a shot in the dark! :)
No go, unfortunately, same crash/stack trace as before: https://gist.github.com/bradleythughes/3954a110d43d805b034f9c5047b4a7f8#file-core-txt-1
As I said before, I am happy to try whatever you need. I am not afraid to help dig into the code, either. I know C well, but have very little knowledge about drivers and the kernel interfaces they use (but I'm a fast learner). In other words, I can hack on the code if you need me to; I will just need some guidance and help along the way. :)
Thanks for looking into this! I would love to run FreeBSD on this machine at some point :D
It seems that the issue is because ath10k_wmi_tx_beacons_nowait is holding the conf lock, a non-sleepable lock while, ath10k_htt_rx_ring_refill is trying to lock on a non-sleepable rx lock. The thing about dma buffers is you cant make them while being locked on another lock, or so far thats how i'm seeing it the "freebsd" way. lol
Hey I submitted some changes I worked on to my repository under this branch, it compiles and I believe it solves your issue, please let me know.
https://github.com/Geramy/athp/tree/athp_parent_dma_allocate
I am new at this and maybe I thought I solved your issue butttttt it looks promising to what i did and what your bug was and I was able to easily find what the crash log said due to my recent discovery of the lock issues that happen 👍
Howdy! I tried the updated athp_parent_dma_allocate branch, and good news! No panic on driver load :)
It seems to get stuck in a loop after loading it though. It also panicked when I tried to unload the driver, but based on the output that's not surprising. Crash info is here: https://gist.github.com/bradleythughes/3954a110d43d805b034f9c5047b4a7f8#file-core-txt-2
The dmesg output from the driver is in the dump, which I've copied below:

You might be missing the firmware files in /boot/firmware
idk about the directory "athp_QCA6174_hw3.0/firmware-5.bin"
As requested, here is PCI info about the device, from pciconf -lv:
none8@pci0:2:0:0: class=0x028000 card=0x143a1a56 chip=0x003e168c rev=0x32 hdr=0x00
vendor = 'Qualcomm Atheros'
device = 'QCA6174 802.11ac Wireless Network Adapter'
class = network
Hey, I tihnk part of the problem is we don't have the right revision setup for this chip.
we have 0x30 0x20 0x10 but not 0x32. let me know if you see that too
Thats not the problem.
Just to verify the two files names you should have are, athp_QCA6174_hw3.0_firmware.bin and athp_QCA6174_hw3.0_board.bin under the firmwares folder.
You may want to try a different firmware file.
https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0
and read the following:
https://askubuntu.com/questions/1063679/ath10k-and-qca6174-causing-pcie-errors-firmware-crashes-and-connection-drops
Is there a firmware version 6
Please try my new branch, I think I may have made a bad change as in I tested it but for some reason it didnt fully rebuild or something so when I tested it, I thought the change worked, I just retested it and found it it was having issues with the changes I made, so I made a small bug fix which should have fixed the bug I had made. It did not undo my dma changes, it just fixed the bug that stopped the firmwares from loading. now it loads. https://github.com/Geramy/athp/tree/tx_power_change
When you are done trying that I have a new branch i've jsut tested and it seems to be amazing :) https://github.com/Geramy/athp/tree/NEW_ATHP_ARVIF_LOCK
It starts so quick after the locking changes I have made, its great. LMK what happens thanks!

I'm using the ARVIF_LOCK brach;
root@Radagast:/home/lbalbi/Src/athp/athp # git branch
- NEW_ATHP_ARVIF_LOCK
And tried all firmwares from : https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0
Do I'm making something wrong, or missing something?
I can test any code you wish, if this help.
I've put the core.txt at https://drive.google.com/drive/folders/12m3JDlMCeK-YYgNQeaJTK6dp2D_ytMgQ?usp=sharing.
Thank's in advanced
