Thermald 2.3-4 has been updated recently to 2.4.3-1ubuntu2 with some relevant upstream fixes. Do you mind verifying if this now addresses the issue. The updates contain the following fixes:
thermald (2.4.3-1ubuntu2) hirsute * Support Jasper Lake. (LP: #1940629) - 0014-Added-Jasper-Lake-CPU-model.patch thermald (2.4.3-1ubuntu1) hirsute * Pull in bug fixes between 2.4.3 and 2.4.6 (LP: #1931565) - Disable legacy rapl cdev when rapl-mmio is in use This will prevent PL1/PL2 power limit from MSR based rapl, which may not be the correct one. - Delete all trips from zones before psvt install Initially zones has all the trips from sysfs, which may have wrong settings. Instead of deleting only for matched psvt zones, delete or all zones. In this way only zones which are in PSVT will be present. - Check for alternate names for B0D4 device B0D4 can be named as TCPU or B0D4. So search for both names if failed to find one. - Fix error for condition names The current code caps the max name as the last condition name, which is "Power_Slider". So any condition more than 56 will be printing error, with "Power_Slider" as condition name. For example for condition = 57: Unsupported condition 57 (Power_slider) - Set a very high RAPL MSR PL1 with --adaptive After upgrading Dell Latitude 5420, again noticed performance degradation. The PPCC power limit for MSR RAPL PL1 is reduced to 15W. Even though we disable MSR RAPL with --adaptive option, it is not getting disabled. So MSR RAPL limits still playing role. To fix that set a very high MSR RAPL PL1 limit so that it never causes throttling. All throttling with --adaptive option is done using RAPL-MMIO. - Special case for default PSVT When there are no adaptive tables and only one default PSVT table is present with just one entry with MAX type. Add one additional entry as done for non default case. - Increase power limit for disabled RAPL-MMIO Increase 100W to 200W as some desktop platform already have limit more than 100W. - Use Adaptive PPCC limits for RAPL MMIO Set the correct device name as RAPL-MSR so that RAPL-MMIO can also set the correct default power limits. If this fixes the issue please let us know. ** Summary changed: - system slagish, thermal keep frequency at 400MHz + system sluggish, thermal keep frequency at 400MHz ** Changed in: thermald (Ubuntu) Importance: Undecided => Medium ** Changed in: thermald (Ubuntu) Status: New => Incomplete ** Changed in: thermald (Ubuntu) Assignee: (unassigned) => Colin Ian King (colin-king) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901266 Title: system sluggish, thermal keep frequency at 400MHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1901266/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
