Re: Moving Linux kernel to 4.19

Hi, I recently updated kernel to 4.19.34-v7+ #1211, and memory cgroups does not work anymore. It is important to bring my kubernetes cluster back to life. Do you have any workaround? Thank you! Not as of yet. I know there was some cgroup work done in the 4.19.34 kernel so it obviously had a negativ...

Re: Moving Linux kernel to 4.19

I was just poking around 4.19.34 and there is some cgroup work present. Could it be? At long last....something [1]?

Re: Moving Linux kernel to 4.19

I've tried that last patch and it didn't fix the problem. A lot of the other proposed patches floating around on the mailing list have either already applied. One of them was applied upstream, then churned a bit and then reverted. If anybody could link me to some other patches or commits, I could g...

Re: Moving Linux kernel to 4.19

Still not fixed in 4.19.29. Memory leak in caches always kills the system. Memory leaks during file operations so it happens faster when user performs some heavy file system jobs like people mentioned earlier on this forum. From what I can see in 4.19.30 relnotes, no ext4 fixes went in that might f...

Re: Moving Linux kernel to 4.19

Did I not read somewhere that the 4.18 kernel is where *full* and *complete* Pi 3/3+ support came about? I would have surmised that it would have made more than some difference in performance. Iff you run the mainline kernel then this would be important. The majority of people don't, therefore it m...

Re: Moving Linux kernel to 4.19

Phoronix did a benchmark of 4.14 against 4.19 (https://www.phoronix.com/scan.php?page=article&item=raspberrypi-linux-419&num=1). Surprisingly, 4.19 is not substantially more performant. :cry: Too bad. Here's hoping later 4.19.x kernels and a final Buster can regain *some* performance in the future....

I just saw that buster got bumped to 18.3.4 which should help even more.
Tried it on Friday, and yes x is working again with buster and 18.3.4. Onwards and upwards.

And if they manage to squeeze 1.20.4 in under the wire, we'll be better off as well I would surmise.

What issues are you seeing with fkms? I thought I'd got to the bottom of the issue on fkms and it is working fine for me. Buster appears to have a broken Mesa at the moment though, so x is giving me issues. Just another thing to investigate. Hoping Buster will be updated to Mesa 18.3.4. I saw a cou...

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...

Re: Moving Linux kernel to 4.19

don't know does it call firmware or not? but saw it in github 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. He's correct since at lea...

We have now bumped the master branch of rpi-update to 4.19 kernel for wider testing.
This is great news. Should bring a lot more performance and possibilities to all the Pis out there. Thanks Devs!

Re: 4.19 kernel 64 bit support - please report issues here

There's a new Debian version (9.8) to be minted on the 16th so I imagine that a new Raspbian will follow some time shortly thereafter. The 4.19.21 kernel was just released yesterday so I would guess the update for Pi will come in a weeks time or less. Quite a few fixes in the .21 release. I just sa...

Don't know how much it'll help but the 4.19.19 update was pushed the other day. From what I can see, the BCM2708, 2709 and 2710 drivers were updated against 4.19.19 as well. They were at 4.19.4 or 5 last I checked. So, might have improved things a tad. Care to test and report back? I tried upgradin...

Are you using the latest mesa? I noticed Eric and Rasterman have fixed few VC4 issues in 18.3.3 https://mesa3d.org/relnotes/18.3.3.html. But unless I am mistaken, that would only work / help against the DRM driver from Eric, right? Haven't heard too much positive news about 18.3, especially for AMD...
