Finally i was able to upgrade kernel without losing performance..
I moved form 4.4.39 to 4.4.126 without losing performance..Testing it for four days, i feel a good performance.

Still using the highest available LTS kernels in both distros...

Same Devuan install since the first beta... :mrgreen:

Linux 4.9.0-0.bpo.6-amd64 #1 SMP Debian 4.9.82-1+deb9u3~bpo8+1 (2018-03-22) x86_64 GNU/Linux
I keep PCLOS around (on a separate SSD) for multimedia and such...although, the last round of updates broke FF Multi Converter (won't even open and I'm too lazy to fix it :P )...

Code: Select all

Here's a little tip for you PCLOS users, new kernel install(s) may bork your sensors config, just run sensors-detect as root (assuming you have lm_sensors and hddtemp installed already), then re-config gKrellm or whatever your fave sensor app is.

Found a workaround for FF Multi Converter in PCLOS (it still wouldn't launch after the latest upgrade), I changed the Desktop launcher command to

Code: Select all

gksu ffmulticonverter
and run it as root, then change the files' permissions to users-read/write in Thunar as root. I have to down-covert TV shows to old .mpg(2), that's the only way my old/cheap DVD player's USB port will play them from a stick. Problem solved.

I went back to 4.4.39, I wont search for another kernel anymore. From that version on, my laptop come into cpu's obsolescence gap; my system (Extensa5230) works perfect with that version's kernel. Being In linux for several years and upon my own experience, I dont worry anymore about security threads, I'll priorize performance. I prefer to keep hold some apps and libraries in order to maximize performance and behavior if possible.

I compiled the upstream kernel from source and installed firmware, including wl module from stretch-backports. Disabling debugging by using

Code: Select all

scripts/config --disable DEBUG_INFO
saved a lot of compile time, so it compiled in about 1h and 25 min.
I wanted to try out new power-saving feature.
My CPU is fluctuating between 0 and 55% for no apparent reason, and my hard drive is being active while doing nothing. As a result, battery is draining, fast. Surprisingly, Broadcom wi-fi card is working.
In short, try not to do this at home and stick to the Debian's kernel :D
I will try to remove intel-microcode, see if that helps.

Update: It seems to have been stable after installing stretch's microcode, not the one from backports. HDD activity is normal.
Update2: Removing microcode again, CPU seems to be at 100% sometimes when playing 720p+ videos on Youtube. This benchmarking is troublesome indeed.
And what-do-you-know, it worked.

You can also install ubuntu's kernel in 5 minits and avoid problems.., I would do so.. :twisted:, Im using ubuntu's kernel for tree year now Im too old to complicate my life.

By the way, Im now gonna install and test 4.17.1 now from ubuntu's ftp.

^Ok, report on how it goes on your end.
I compiled it because that's the best way to experience upstream stable kernel without extra patches from dowstream. Time spent on it didn't affect me since I wasn't doing anything special at the moment that required my laptop.

I removed intel-microcode, it works even better now than before. Plus I got rid of some non-free stuff, so there's that :)

Don't guess---install spectre-meltdown-checker to see for sure. Use the latest script from git to get the bad news about newer Spectre variants...not that there's any mitigation for those yet. :(

Thanks Steve,
I installed it... but I already went back to 4.4.39, I can live with Meltdown and company..they wont hurt me.

I built the latest LTS kernel. Only thing I needed to do is build broadcom-sta-source from backports. It's easy with module-assistant.

Doesn't it work with broadcom-sta-dkms from backports to automate the builds?

For what it's worth, I'm also backporting the upstream Debian kernels to Stretch in an OBS repo:

https://build.opensuse.org/package/show ... linux-4.17

Works fine on my machine, even with the new 20180703.2 firmware backported. But YMMV.

Instructions (don't install the linux-source-4.17 package, that's just a common package between the builds needed to access the automatically-generated instruction page on the OBS. Just install the new linux-image and linux-headers after adding the repo and its key.)

It should work, but I decided against it.
Don't know why, maybe this way was more "fun", or at least more involving. I will be upgrading kernels manually...I have the LAN cable at the ready if it's needed.
I also copied firmware from upstream git for my AMD R5 330m card to /lib/firmware/radeon. Naturally, firmware-adm-graphics package was uninstalled, as it's no longer needed.

EDIT: Linux 4.14.53 is running here without any issues.
EDIT2: Video playback on X in Totem skips and micro-freezes. Audio also grinds on some programs. Cue Wayland, and everything works great. Weird.

Today I'm running a few vms on VirtualBox, so booted from the 4.14 kernel.

Code: Select all

cat /proc/version 
Linux version 4.14.0-0.bpo.3-amd64 (debian-kernel@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18)) #1 SMP Debian 4.14.13-1~bpo9+1 (2018-01-14)
Other days, I'll use one of the other backport kernels; 4.15, 4.16, 4.17.
