Yeap it helps and it is quite clear. Still another remark. Sorry for going on with the digression here. If there is a more proper channel we can move there.

[Ubuntu-x-swat] [Bug 1768976] Re: Ubuntu 18.04 is overheating after upgrade from 16.04
Each CPU can have a different request into the PLL (phase locked loop), but the highest one wins, and their vote does not count if they are in an idle state deeper than C1. You can observe this manually by reading the pstate request and granted MSRs directly (requires msr-tools, and the msr module must already be loaded). Example (requested, granted, 100% load on CPU 3): root@s15:/home/doug/temp-git-git# rdmsr --bitfield 15:8 -d -a 0x199 16 16 16 38 16 16 16 16 root@s15:/home/doug/temp-git-git# rdmsr --bitfield 15:8 -d -a 0x198 36 35 36 36 36 36 36 36 Where 38 is the max and 16 in the min for my i7-2600K. Why only 36 granted? because actually I guess three cores are active at the time of the sample. From turbostat: cpu0: MSR_TURBO_RATIO_LIMIT: 0x23242526 35 * 100.0 = 3500.0 MHz max turbo 4 active cores 36 * 100.0 = 3600.0 MHz max turbo 3 active cores 37 * 100.0 = 3700.0 MHz max turbo 2 active cores 38 * 100.0 = 3800.0 MHz max turbo 1 active cores Note: I ran the above as root because there is a lot over overhead running it under "sudo", which tends to result in another CPU requesting a high pstate by the time the sample is actually taken. Now, the different reported CPU frequencies, for your example where there is no dominant load, is another story. While there is only one PLL, your mostly idle CPUs would be "awake" at different times, with the PLL ramping up and down based on which incoming votes and requests are being used.

I guess you mean "there is only one PPL in the CPU, all cores get the resulting clock".

There is only one PLL (Phase Locked Loop) in the processor, all CPUs get the resulting clock. When they go into deep idle states (deeper than C1, at least for my processor) then they give up their vote into the PLL as to what the frequency should be. Your single 100% task is dedicating the CPU frequency for all, for when they are active. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1768976 Title: Ubuntu 18.04 is overheating after upgrade from 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768976/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

@Doug Smythies: thanks for the reply. I'm sampling every second. Anyway, just to better understand. When my system is idle all cores spend in C0 less than 10% of the time and the frequency of each core reported by i7z is different and below 2.2GHz. When I run a single core (and single thread) task, there is just core "0" which is 100% of the time in C0 state (as it should) but I would have expected only such core to reach ~2.9GHz and the other to remain in below.

@Davide Sangalli: What you describe and show in your comment #80 is correct and exactly what should happen. Your processor is spending an extraordinary amount of time in C1 as opposed to deeper idle states. At what sampling frequency do you run i7z? I would suggest once every 15 seconds or so, so that you don't wake up CPUs just to ask them status stuff.

An update. After some digging the conclusion I is that the problem in my case is not linux but might be the Asus BIOS. Even just enetering the BIOS the CPU temperature is rising up to 70-80 degrees. I'v e also upgraded the BIOS, but without significant improvements. I have the impression the BIOS has problems in dealing with the intel turbo boost technology of my i7-8th generation.

Followed instructions from #67. Running 'cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver' to check for frequency scaling driver shows 'acpi-cpufreq' instead of 'intel_pstate', even *before* adding 'intel_pstate=disable' to /etc/default/grub. After adding 'intel_pstate=disable' to /etc/default/grub and rebooting, 'cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver' shows 'acpi- cpufreq' as frequency scaling driver, too. In my case, using kernel 4.15.0-45-generic, 'intel_pstate' frequency scaling driver has never been shown as active, yet the processor overheating continues.

I'll leave my hardware specs here, it could help pinning down the problem cause. I'm using NVidia driver 340.107.

Same symptoms here and no nvidia GPU, only "simple" Intel. Since this version, temp is very high.

Ubuntu offered me a security update. It was offering it for a long time and I didn't want to take it, because I didn't wanted to mess it up. But installed all, and it messed it up with kernel 4.15: it couldn't install the 340 nvidia driver I need into the new kernel. It became an endless loop when ran the new kernel version (4.15). I read somewhere that this might be because of video driver. I started the last working linux kernel and activated nouveau. 4.15 kernel started this way, but overheated in a minute and shutted down. What I did is: started linux in command line mode and blacklisted nouveau, downloaded 340 nvidia from nvidia website and installed it manually (without DKMS, because it didn't work). Now there is no overheat. Nouveau is the one to blame imo. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1768976 Title: Ubuntu 18.04 is overheating after upgrade from 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768976/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

A small detail - I actually have a 2500K but there was a regression in the xserver with 18.04 (16.04 worked fine but 18.04 cause a bug that existed in 14.04 (I think - i had this problem after 12.04 I think but it was a long time ago) to reoccur and the intel graphic would cause crashes) so I purchased a R72402364P - anyway an strace shows this small tidbit with the xserver spinning): (I filtered out other stuff the xserver is doing but as you can see from the timing it is spinning on ioctl calls): -- 1540153775.186129 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3f50) = 0 1540153775.186613 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.186650 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.186690 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.186723 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.186757 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.186788 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.186818 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.186849 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.186993 ioctl(16, DRM_IOCTL_RADEON_GEM_WAIT_IDLE, 0x7ffd14ed46e0) = 0 1540153775.187389 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.187425 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.187460 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.187492 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.187611 ioctl(16, DRM_IOCTL_RADEON_GEM_WAIT_IDLE, 0x7ffd14ed46e0) = 0 1540153775.188095 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.188130 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.188264 ioctl(16, DRM_IOCTL_RADEON_GEM_WAIT_IDLE, 0x7ffd14ed46e0) = 0 1540153775.188579 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188605 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188628 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188652 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188675 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188698 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188721 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188744 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188768 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188793 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188816 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188840 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188863 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188904 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188930 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188953 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188977 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189000 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189024 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189047 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189071 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189094 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189118 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189323 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed4150) = 0 1540153775.189363 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed40f0) = 0 1540153775.189417 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.189451 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.189487 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.189518 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1768976 Title: Ubuntu 18.04 is overheating after upgrade from 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768976/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[Ubuntu-x-swat] [Bug 1768976] Re: Ubuntu 18.04 is overheating after upgrade from 16.04
apport information ** Tags added: apport-collected ubuntu ** Description changed: Ubuntu is overheating at my laptop. Opening youtube on firefox is enough for critical temperature shutdown. Using lm-sensors for monitoring on 18.04 the temp varies between 70 and 85°C with only firefox or chrome open and doing nothing. On my old 16.04 with same using, the temp varies between 55 and 70°C. First thought was the driver nouveau is the problem, and finally I was able to install by add "nouveau.modeset=0" at livecd boot options, without temp shutdown. After install I disable the nouveau at modprobe blacklist, but the system continues overheating and shutdown with basic usage. I have no idea what's happening with the bionic at my laptop. My laptop is a Samsung RF411 i5 2nd Generation and Geforce 540M.

I had a similar problem. turns out it was actual high load that forced the cpu clock speed to always be more than 3GHz on all (!) cores. namely the xorg (>100%), systemd-journald (>50%) and rsyslogd(>30%) were consuming a lot cpu power. in the journal i could see the following line over and over again: SynPS/2 Synaptics TouchPad: Read error 9 After a bit of digging I found that the synaptics driver should be replaced with the xserver-xorg-input-libinput. (which I had already installed, maybe that was the problem) see: https://wiki.ubuntuusers.de/Touchpad/ So after removing the package xserver-xorg-input-synaptics the cpu load went down significantly and so did the cpu-clock and heat. problem solved for me -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1768976 Title: Ubuntu 18.04 is overheating after upgrade from 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768976/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I have the same heating issue after a clean install of Ubuntu 18.04. Before that I was using Ubuntu 16.04, without this problem. Fans are more active than before and the laptop is constantly overheated, with 70-80 degrees doing nothing but only Chrome or even with the shell opened. Nvidia drivers has been removed (I can live with the integrated Intel). Kworker issue (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793) already fixed.
