Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit Dear Linux folks, I wonder what C-States I can expect, when connecting a USB-C adapter to a laptop, like Dell DA300 to my Intel Kaby Lake laptop Dell XPS 13 9360. My tests with Linux 6.10.0-rc4 show, that with $ echo 8 | sudo tee /sys/kernel/debug/pmc_core/ltr_ignore – otherwise only PC8 seems to be reached – I get: ### Dell DA300 connected (to only USB-C port on the left) with Ethernet cable connected PC6 is reached: ``` $ sudo turbostat --quiet --show CPU%c1,CPU%c6,CPU%c7,GFX%rc6,Pkg%pc2,Pkg%pc3,Pkg%pc6,Pkg%pc7,Pkg%pc8,Pkg%pc9,Pk%pc10,SYS%LPI rtcwake -m freeze -s 10 rtcwake: assuming RTC uses UTC ... rtcwake: wakeup from "freeze" using /dev/rtc0 at Thu Jun 20 20:06:54 2024 11.480088 sec CPU%c1 CPU%c6 CPU%c7 GFX%rc6 Pkg%pc2 Pkg%pc3 Pkg%pc6 Pkg%pc7 Pkg%pc8 Pkg%pc9Pk%pc10 SYS%LPI 1.54 1.00 95.57 18265.79 1.68 93.68 0.00 0.00 0.00 0.00 0.00 0.00 1.44 0.54 95.68 18266.07 1.68 93.68 0.00 0.00 0.00 0.00 0.00 0.00 2.20 1.55 1.46 95.45 0.97 ``` ### Unplugged Dell DA300 (no devices connected) PC9 is reached: ``` $ sudo turbostat --quiet --show CPU%c1,CPU%c6,CPU%c7,GFX%rc6,Pkg%pc2,Pkg%pc3,Pkg%pc6,Pkg%pc7,Pkg%pc8,Pkg%pc9,Pk%pc10,SYS%LPI rtcwake -m freeze -s 10 rtcwake: assuming RTC uses UTC ... rtcwake: wakeup from "freeze" using /dev/rtc0 at Thu Jun 20 20:07:15 2024 10.816703 sec CPU%c1 CPU%c6 CPU%c7 GFX%rc6 Pkg%pc2 Pkg%pc3 Pkg%pc6 Pkg%pc7 Pkg%pc8 Pkg%pc9Pk%pc10 SYS%LPI 1.44 0.77 95.66 19577.75 1.35 21.72 0.05 0.00 71.97 0.00 0.00 0.00 0.72 0.64 96.47 19577.79 1.35 21.72 0.05 0.00 71.97 0.00 0.00 0.00 1.30 2.60 0.91 94.85 1.14 ``` Sometimes I have reached PC10 already, but no idea if I had something connected before. ### Dell DA300 connected (to only USB-C port on the left) with nothing connected to the adapter PC6 is reached: ``` $ sudo turbostat --quiet --show CPU%c1,CPU%c6,CPU%c7,GFX%rc6,Pkg%pc2,Pkg%pc3,Pkg%pc6,Pkg%pc7,Pkg%pc8,Pkg%pc9,Pk%pc10,SYS%LPI rtcwake -m freeze -s 10 rtcwake: assuming RTC uses UTC ... rtcwake: wakeup from "freeze" using /dev/rtc0 at Thu Jun 20 20:07:39 2024 11.086315 sec CPU%c1 CPU%c6 CPU%c7 GFX%rc6 Pkg%pc2 Pkg%pc3 Pkg%pc6 Pkg%pc7 Pkg%pc8 Pkg%pc9Pk%pc10 SYS%LPI 1.56 0.71 95.96 19316.43 1.60 93.62 0.00 0.00 0.00 0.00 0.00 0.00 1.22 0.66 96.25 19316.93 1.60 93.62 0.00 0.00 0.00 0.00 0.00 0.00 1.57 1.85 0.75 95.66 1.62 ``` Does it depend on the adapter, or is it not possible to reach lower states than PC6 with something plugged in?
