Redpine: BLE radio lost issue

[Amitkumar Karwar]

SRU Justification

Impact: Radio stops capturing advertisements after several hours.

Fix: Updated firmware.

Test Case: See below.

Regression Potential: Limited to specific hardware.

---

Below are the steps to replicate the issue

We are doing continuous BLE scanning and monitoring the advertisements from reference device. After long periods of capture (several hours), the radio stops capturing advertisements and won't start again until we power cycle the box or manually unload/load the module via modprobe

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1757443

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

[Shrirang Bagul (shrirang-bagul)]

Required for both Xenial as well as Bionic.

[Seth Forshee (sforshee)]

Applied for xenial. The patch sent to the list cannot be applied for bionic becuase the firmware does not exist there yet. If the firmware is needed for bionic someone will need to submit a pull request to add it.

[Seth Forshee (sforshee)]

Oh and the bionic kernel is also missing the driver for the kernel patch.

[Shrirang Bagul (shrirang-bagul)]

The Bionic kernel will switch to the existing driver in the kernel (http://kernel.ubuntu.com/git/ubuntu/ubuntu-bionic.git/tree/drivers/net/wireless/rsi) to support RS9113 WiFi+BT combo module on Dell Edge 300X IoT gateways.

HWE is working with Redpine to fix issues in this driver to for 18.04 server support.

[Seth Forshee (sforshee)]

In that case I'd suggest someone send a pull request for adding the firmware from bionic. However if the driver that needs the firmware is upstream then it would also make sense to get the firmware into upstream linux-firmware.

[Shrirang Bagul (shrirang-bagul)]

Yes, for Bionic, Redpine will push their FW into upstream linux-firmware.

[Shrirang Bagul (shrirang-bagul)]

For Xenial, when can we expect the Ubuntu-1.157.18 release?

[Amitkumar Karwar (amitkarwar)]

Reply C#7,

Latest Redpine firmware(1.6.1) is already available in upstream linux-firmware.git
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/rsi

[Seth Forshee (sforshee)]

I uploaded 1.157.18 last week, it's still sitting in the unapproved queue though.

[Łukasz Zemczak (sil2100)]

Accepting this for xenial. Normally we'd block until the fix is in the devel release, but in this case the required firmware is not present in that release (so we're not regressing with the upgrade path). But please SRU the fixes with the firmware itself to bionic if ready.

[Łukasz Zemczak (sil2100)]

Hello Amitkumar, or anyone else affected,

Accepted linux-firmware into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/1.157.18 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Seth Forshee (sforshee)]

@Amitkumar, just to confirm if I update bionic's linux-firmware with the latest upstream driver it will have all needed fixes?

[Amitkumar Karwar (amitkarwar)]

Yes. Upstream linux-firmware.git has all the fixes

[Seth Forshee (sforshee)]

Thanks, I've updated the firmware in git for bionic. Will upload that once I finish with another update.

Also, please note that the update for xenial is in -proposed and needs verification.

[Brian Murray (brian-murray)]

Could you please provide some information about how you verified the fix for xenial?
