[PATCH] ath10k: qmi: Skip host capability request for Xiaomi Poco F1

[Amit Pundir]

Workaround to get WiFi working on Xiaomi Poco F1 (sdm845)
phone. We get a non-fatal QMI_ERR_MALFORMED_MSG_V01 error
message in ath10k_qmi_host_cap_send_sync(), but we can still
bring up WiFi services successfully on AOSP if we ignore it.

We suspect either the host cap is not implemented or there
may be firmware specific issues. Firmware version is
QC_IMAGE_VERSION_STRING=WLAN.HL.2.0.c3-00257-QCAHLSWMTPLZ-1

qcom,snoc-host-cap-8bit-quirk didn't help. If I use this
quirk, then the host capability request does get accepted,
but we run into fatal "msa info req rejected" error and
WiFi interface doesn't come up.

Attempts are being made to debug the failure reasons but no
luck so far. Hence this device specific workaround instead
of checking for QMI_ERR_MALFORMED_MSG_V01 error message.
Tried ath10k/WCN3990/hw1.0/wlanmdsp.mbn from the upstream
linux-firmware project but it didn't help and neither did
building board-2.bin file from stock bdwlan* files.

This workaround will be removed once we have a viable fix.
Thanks to postmarketOS guys for catching this.

What happens if you skip sending the host-cap message? I had one
firmware version for which I implemented a
"qcom,snoc-host-cap-skip-quirk".

But testing showed that the link was pretty unusable - pushing any real
amount of data would cause it to silently stop working - and I realized
that I could use the linux-firmware wlanmdsp.mbn instead, which works
great on all my devices...

"Didn't work" as in the wlanmdsp.mbn from linux-firmware failed to load
or some laer problem?

I skipped the ath10k_qmi_host_cap_send_sync block altogether
(if that is what you meant by qcom,snoc-host-cap-skip-quirk) and
so far did not run into any issues with youtube auto-playback loop
(3+ hours and counting). Does that count as a valid use case?
Otherwise let me know how could I reproduce a reasonable test
setup?

While using the wlanmdsp.mbn from linux-firmware, I run into
the following crash 4 times before tqftpserv service gets killed
eventually:

ath10k-check complained about a too long line, so in the pending branch
I moved the comment before the if statement.

Iirc I was able to get an IP but browsing the web would be enough
traffic to stop (without any visible faults from the driver).

So your test sounds good I would like to see a host-cap-skip quirk,
rather than a conditional on the machine compatible.

It loaded, but doesn't seem to come up properly. We can try to debug
this further, but I think getting the quirk in will be useful - as there
seems to be a generation of firmware that has this particular behavior.

As I wrote in the answer to Amit I think we should introduce a generic
quirk to skip host_cap instead.

So if you pick this up (which is an ok short term workaround) I think we
should revert it once we have a generic mechanism.

Hi Bjorn, just sent out a generic skip quirk for review.
