--- Begin Message ---Package: src:linux Version: 6.0.3-1 Severity: important Hello, starting with 5.18.0-3-amd64 I experience significant performance loss (clock speed slows down to 400 MHz) on higher CPU usage. After checking for differences I figured out that the long-term intel rapl mmio power limit now defaults to 5W (AC mode) / 10W (battery mode) compared to 25W with 5.18.0-2-amd64: AC mode: $ uname -a Linux sulfur 6.0.0-2-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.0.3-1 (2022-10-21) x86_64 GNU/Linux $ cat /sys/class/power_supply/AC/online 1 $ cat /sys/class/powercap/intel-rapl-mmio/intel-rapl-mmio\:0/constraint_0_power_limit_uw 5000000 Battery mode: $ uname -a Linux sulfur 6.0.0-2-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.0.3-1 (2022-10-21) x86_64 GNU/Linux $ cat /sys/class/power_supply/AC/online 0 $ cat /sys/class/powercap/intel-rapl-mmio/intel-rapl-mmio\:0/constraint_0_power_limit_uw 10000000 Note that the limit in battery mode is actually higher than in AC mode. Booting into 5.18.0-2-amd64 the default power limit is 25W: AC mode: $ uname -a Linux sulfur 5.18.0-2-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1 (2022-06-16) x86_64 GNU/Linux $ cat /sys/class/power_supply/AC/online 1 $ cat /sys/class/powercap/intel-rapl-mmio/intel-rapl-mmio\:0/constraint_0_power_limit_uw 25000000 Battery mode: $ uname -a Linux sulfur 5.18.0-2-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1 (2022-06-16) x86_64 GNU/Linux $ cat /sys/class/power_supply/AC/online 0 $ cat /sys/class/powercap/intel-rapl-mmio/intel-rapl-mmio\:0/constraint_0_power_limit_uw 25000000 I can manually set the power limit to 25000000 (fixing the performance issues), but the embedded controller changes it back to 5000000 after some time. Please let me know if I can provide any further information.
