[Bug 1944389] Re: Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz
I've performed measurements with turbostat (kernel 5.13)
With new thermald ("bad" game performance):
GFXAMHz: 400, PgkWatt: 16.56, CorWatt: 7.34, GFXWatt: 3.88
With old thermald (good performance):
GFXAMhz: 650, PkgWatt: 14.86 CorWatt: 3.81, GFXWatt: 4.45
About game mode daemon: I have gamemode installed but I'm not sure
whether it is actually used. I remind that have it installed just in
case, but I heard about this program (it is useful for AMD CPUs with
discrete GPUs to set "performance" CPU governor during playing)
It could be a good idea to utilize it, however I have a concern that
most of "typical users" who want to play on their laptops don't know
about this program.

I also checked with GTA IV game -- with the new thermald performance also decreased. Average FPS for in-game benchmark drop from 53 to 42 (I run only one attempt for each thermald version) (and game became unplayable as minimum FPS in complex scenes became less than 30). GTA IV has a different CPU load pattern: while STALKER loads only one CPU core but to 100%, GTA IV looks to be multi-threaded -- it utilizes all cores but all of them partially (no one was > 50%). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944389 Title: Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1944389/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you, Srinivas! I'll try to perform the tests with the proposed
configuration on the weekend.
Game: https://store.steampowered.com/app/20510/STALKER_Clear_Sky/ it costs 9.99
EUR but I'll be happy to buy it for your for the test purposes.
To run it with Steam on Linux one should enable "Steam Play" in Steam settings
("For selected titles" and "For all other titles" (I selected as compatibility
tool Proton 5.0-10, but it also runs fine with the other versions)
The game graphics configuration (steamapps/common/STALKER Clear
Sky/_appdata_/user.ltx) is attached. I run it on external 2560x1440 144 Hz
display (USB-C=>HDMI cable)

Srinvas, thank you for the explanation. But could you also explain what do you mean by > It only reduced total power Are these 15 Watts limit (after reaching 53 degrees) for the whole Core i7 chip (CPU+GPU+..) or for GPU chiplet only? If this limit is for the whole chip than something is wrong with thermald, because overall power consumption with new thermald is significantly bigger (because of higher temperature / fan RPM) and the CPU frequency is almost two times higher (2.4 vs 1.3 GHz).

[Bug 1944389] Re: Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz
I just checked old and new behavior again. First of all it's not clear for me from where this value of 53 is taken, according to the data in /sys/class/thermal/thermal_zone5 (THP) trip_point_0_hyst:4000 trip_point_0_temp:-274000 trip_point_0_type:passive trip_point_1_hyst:4000 trip_point_1_temp:-274000 trip_point_1_type:passive trip_point_2_hyst:4000 trip_point_2_temp:80050 trip_point_2_type:critical trip_point_3_hyst:4000 trip_point_3_temp:75050 trip_point_3_type:hot trip_point_4_hyst:4000 trip_point_4_temp:65050 trip_point_4_type:passive and the same values are shown for THP by old thermald (via ThermalMonitor): THP: 65 Passive 75 Max 80 Critical 58 Polling For new thermald with --adaptive THP values (via ThermalMonitor) are the following: 52 Passive 46 Polling and doesn't comply with data from /sys/class/thermal/thermal_zone5/ I'll be grateful if you could explain me what I missed, but I believe that it could be so -- at least it looks like thermald tries to maintain 53 degree value. But regarding my issue I can tell you some measurements: With old thermald zone5 (THP) temperature is kept 53-56 during the load, CPU temperature 60-64, CPU frequency 1.3-1.4 with new thermald zone5 (THP) temperature is also kept 53-56 during the load, CPU temperature 70-74 CPU frequency 2.4 (up to 2.7) and amount of noise is bigger. So it looks like thermald tries to keep THP temperature within limits by decreasing the GPU frequency, but as far as GPU chip is on the same die with CPU and shares the cooling fan, thermald is not succeed -- because the CPU heats the GPU chip. So my biggest concern and suspicion here is that new thermald (with --adaptive) sacrifices GPU by CPU -- it makes GPU run on lower frequencies in favor of allowing CPU run on higher ones. Maybe it is reasonable for some loads (I can hardly imagine for which ones?) but not for end-user laptop and especially for gaming/3D or 4K accelerated video from Youtube -- if there is a high demand for GPU it means that it would mostly affect performance, latency and overall end-user experience. Tigerlake laptops have more than enough CPU performance for end-user but a very weak GPU and even this GPU is throttled in case of serious load. I understand that it would be better to have some option, what to prioritize GPU or CPU, but for majority of end-users (and this Tigerlake is not a tool for ones who want to run a heavy computing tasks) the GPU prioritization would be more desired and expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944389 Title: Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1944389/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1944389] Re: Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz
I've checked with the latest git version -- it has the same problem. New behavior (git thermald, as well as latest Ubuntu version with backports): thermald keeps the GPU frequency at 400 Hz after reaching 85 degrees, even if temperature decreases to 74. After the thermal regime stabilizes there are following measurements: GPU freq 400MHz CPU freq 2.4GHz Package temperature: 74 degrees FPS is 25-35 -- it's impossible to play the game intel_gpu_top displays that "Render/3D/0" engine is busy up to 100%, usually 97-99 Old behavior: thermald starts throttling after reaching 70 degrees but allows GPU to run on 660 MHz After the thermal regime stabilizes there are following measurements: GPU freq 660MHz CPU freq 1.3GHz Package temperature: 64 degrees FPS is 45-53 -- game is playable intel_gpu_top displays that "Render/3D/0" engine is almost always busy at 100% So new thermald ignores GPU demand and sacrifices the GPU performance in favor of CPU and at the same time keeps the higher temperature. I also have found a workaround -- to disable the new behavior one needs to remove the "--adaptive" switch. W/o it the new version works as the old one with that switch. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944389 Title: Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1944389/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1944389] [NEW] Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz
Public bug reported: After update to 1.9.1-1ubuntu0.6 from 1.9.1-1ubuntu0.4 thermald keeps Tigerlake Iris Xe GPU frequency on 400 MHz after reaching some high temperature value. It became impossible to play video games on the laptop. System: Ubuntu 20.04.3 LTS Kernel: 5.10.0-1045-oem Laptop: Dell XPS 9310, CPU: Intel Core i7-1165G7 (Tigerlake), Integrated GPU Iris Xe. BIOS 2.1.1 03/25/2021 Display: 2560x1440 144Hz HDMI USB-C connection Room temperature is 23.5-25.4 degrees Game: Stalker Clear Sky (Wine/Proton Steam) Note: The game itself is very old and loads 100% of one CPU core disregarding of frequency. GPU frequency is monitored by intel-gpu-top GPU frequencies (according to /sys/class/drm/card0/) min/max/boost/efficiency: 100/1300/1300/400 Previous behavior (1.9.1-1ubuntu0.4) After starting the game at first GPU reaches the boost value of 1300 MHz and CPU/package temperatures continuously increase. At this point game renders at ~80FPS. After some time when threshold temperature value (~78 degrees) is reached the GPU frequency decreases to ~660 MHz and FPS to 40-48 FPS. Package temperature decreases to 66-68 degrees. It's possible to play for indefinite amount of time. New behavior (1.9.1-1ubuntu0.4) After starting the game at first GPU reaches the boost value of 1300 MHz and CPU/package temperatures continuously increase. At this point game renders at ~80FPS. But after reaching the threshold temperature (about 81 degrees) GPU frequency decreases to 400 MHz (gt_RP1_freq_mhz -- "efficiency" temperature for the GPU) and stays on this value for the indefinite amount of time. The temperature is maintained on 70-74 degrees. FPS is about 25-30 FPS, it is not possible to play the game anymore. The only way to return the good FPS and frequency is to fold the game window, wait some time and open it again. Also there is a workaround -- limit the CPU frequency to 2001 MHz and disable Intel turbo boost. With such approach package temperature never reaches 80 degrees and it is possible to play game with 500 MHz and 35-40 FPS. Better than nothing. If it is needed I can perform any additional checks, provide CPU frequencies and so on. Most probably regression happened with 1.9.1-1ubuntu0.5, but I tried only versions 0.4 and 0.6 ** Affects: thermald (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944389 Title: Thermald 1.9.1-1ubuntu0.6 keeps Tigerlake GPU frequency on 400 MHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1944389/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
