Re: Moving Linux kernel to 4.19

Lack of cgroups is the case. "Edit your command line boot file to enable and mount memory cgroups. This allows AWS IoT Greengrass to set the memory limit for Lambda functions. Without this, the Greengrass daemon is unable to run." - Source: https://docs.aws.amazon.com/greengrass/latest/developergui...

Seems to work fine now. The rsnapshot/rsync command that failed previously completed succesfully now running the latest rpi-kernel update (4.19.30; 00bb2894c0a4349464c19ba62f62b8d9e17a1a9e).
Thanks for confirming.

For AWS Greengrass 4.19 is a no go. No way to setup max memory for local Lambda functions?
I think you'll have to explain more precisely. Are you referring to the lack of cgroups, the slab/inode leak or some other change in 4.19.

Re: Moving Linux kernel to 4.19

Mostly a scheme for isolating resource usage for collections of processes.
Mostly used for virtualisation, or containerisation (like docker).

I don't think 99% of users will notice its absence, but this is what the test builds are for.
If things stop working due to its absence, then report it here.

Re: Moving Linux kernel to 4.19

Potential workaround for the inode slab leak is now available in rpi-update kernel.
Affected users, please update and report back.

The workaround disables memory and IO cgroups which appears to be the cause of the leaks.

Possibly this issue: https://github.com/raspberrypi/linux/issues/2829
It's an upstream issue and solutions are being discussed there.
We'll pick up any fixes when they are decided on.

Since this won't be fixed in mainline, we have two options:
1) update hostapd to a more recent version (e.g. from Buster)
2) revert the mentioned commit
hostapd in raspbian has been updated to version from buster. Hopefully this resolved the issue.

Re: Moving Linux kernel to 4.19

If it helps the hostapd diagnostics, it appears the issue is broader than 4.19. This link shows the same nl80211: Register frame command failed (type=208): ret=-22 (Invalid argument) occurred a few weeks back in 4.14.90-v7+ as well. https://raspberrypi.stackexchange.com/questions/92165/raspberry-pi...

Does it work when gpu_mem=16 is set in config.txt which gives the arm a bit more memory?

one has to remember to uncomment the fake driver with #dtoverlay=vc4-fkms-v3d in /boot/config.txt to avoid the hang
Latest rpi-update kernel should fix the hang when vc4-fkms is enabled. Fix from here.

Re: Moving Linux kernel to 4.19

He's correct since at least yesterday. Not everything is up to 4.19.23. There are many things at (https://github.com/Hexxeh/rpi-firmware) still showing level at 4.14.94 or .98. The kernel update doesn't directly affect firmware or opt/vc libs. So those files will show the last update commit of when...

The first post says that moving to 4.19 for raspian sdcard images and apt upgrades is the final goal. Currently we're still testing with users on rpi-update kernels. A...

Not really sure what you are saying. That shows the kernel and modules are at 4.19.23.
If you want to test it follow instructions in first post of this thread or you can wait until it reaches apt/raspbian later.

Have you run rpi-update? What did it output? Have you rebooted? What does uname -a report?

Of course. Using the Pi as a media player is a very common use.
There's more than a million active users of kodi (mostly OSMC and LibreELEC) on Pi.
It's very straightforward to install.
