Performance of WCN7850

Performance of WCN7850

[Jun Nie]

Hi,

I am trying to maximize the bandwidth of WCN7850. Does anyone know the
performance status of WCN7850 in mainline? It's about 160Mbps in 6GHz
band and ~600Mbps in 5GHz band on sm8650 platform in my test. The
firmware is from below links:
https://github.com/kvalo/ath11k-firmware/raw/master/ath12k-testing/WCN7850/hw2.0/board.bin
https://github.com/kvalo/ath11k-firmware/raw/master/ath12k-testing/WCN7850/hw2.0/regdb.bin

While it is ~940Mbps in both 5GHz and 6GHz band with
Android/linux6.1.25, . But the firmware names are different per log,
amss20.bin on Android. Not sure whether the driver is totally
different for Android/linux6.1.25 and mainline.

Do you have any idea that the low performance on mainline is due to
driver difference or TX/RX power configuration, or firmware version?

Thanks for your input!
Jun

The drivers are different. Android uses the out-of-tree qcacld-3.0 driver.

My expectation is that the upstream mac80211 datapath will never achieve
the same throughput as a custom datapath. That said, the ath12k driver
is still under very active development, and performance tuning will
occur in the future.

Hi Jeff,

Thanks for your input! Do you know where I can find a tool to tune the power
level of 6GHz? Seems that below patch supports it. But I am not familiar with
WiFi software actually.
342527f35338 wifi: ath12k: Add support to parse new WMI event for 6
GHz regulatory

I suppose performance of 5GHz can be aligned with 6GHz, even they are worse
than custom datapath in Android. Is this the right expectation?

Thanks!

That is my expectation. I've made the development team aware of the
discrepancy you are seeing.

Note that in theory you should be able to achieve higher throughput in 6
GHz due to the availability of 320 MHz bandwidth. But when using the
same bandwidth, the performance should be similar.

To debug this issue the development team has asked:
#1) Please change ath12k debug_mask to 0xffffffff
#2) trigger association to 5G AP
#3) reproduce throughput low issue with 5G AP
#4) trigger association to 6G AP
#5) reproduce throughput low issue with 6G AP

Then share the logs with me (redacting anything personal) and I'll pass
them on to the developers.

Thanks

6GHz AP association failure on WCN7850

[Jun Nie]

Hi,

I see there is association failure many times when I try to connect my
6GHz AP with latest mainline Linux. Does anyone also observe it too?
Any newer firmware than WLAN.HMT.2.0-01734 is available? Or we
recommend any specific version firmware?

The issue only happens with this version firmware:
  [    9.441624] ath12k_pci 0000:01:00.0: Hardware name: wcn7850 hw2.0

Wrong firmware.

We use WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 and 
WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4,

That's it, i recommend you to use 
WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3. It's new one.

Can you check if you completely replaces our upstream version?

It is best not to mix it with other versions
(board.bin/board.bin/regdb.bin/amss.bin/m3.bin).

Mixed use may also have an impact on throughput.

If problem still exist, please revert these patches and check again.

Yeah, tried to replace all binaries from below path, but no help.

What's your test platform? I use sm8650-hdk. Not sure whether there is something
platform dependent.
These binary was tested OK with Linux mainline on some QCOM platform, right?

So, both WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4. and 
WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 have this problem? 
Their log is the same?

Our test platform is x86 devices(normal x86 PC or x86 board).

These binary can only be uploaded after detailed testing on x86 platform.

Your platform is arm. Actually, we never test whether upstream firmware 
of ath12k can work well on other platforms. Any errors could happen.



Did you download this firmware by git clone? Or just download manually.

Please retry with git clone if you download manually.

You are right. It is downloading issue. binaries from git clone works well.
But 5GHz performance of version WLAN.HMT.1.0.c5-00481 is worse than
the 600Mbps on version WLAN.HMT.1.0-03427. The 6GHz performance
is similar, ~160Mbps. Do you what's the improvement of new firmware?

Hi Jeff,
The latest finding is that 6GHz TX performance of wcn7850 is as we talked about.
But the RX performance wcn7850 is better than 5GHz case. So the direction
impacts a lot. Not sure whether the bottoleneck is in scheduling side, or any
configuration on TX power.

There is at least one 6 GHz patch in the pipeline that should be posted this week.

Hi Jeff,
What's the performance data with the patch in the pipeline? Is it
possible to have a
early test with my hardware?
