AceLan Kao, In summary, I did not see any improvement, but perhaps some of the extended debugging is helpful. I did the following steps over the course of my work day, so I might have missed a step, but here is the order of what I did:
I added the ubuntu kernel repo: $ sudo add-apt-repository ppa:canonical-kernel-team/ppa I added deb-src: $ sudo sed -i 's/^Types:.*$/& deb-src/' /etc/apt/sources.list.d/canonical-kernel-team-ubuntu-ppa-noble.sources $ sudo apt update I then downloaded the kernel source: $ sudo apt install build-essential $ sudo apt source linux-image-unsigned-$(uname -r) I extracted the source and patched it. $ gunzip linux_6.8.0-43.43.diff.gz $ tar -zxvf linux_6.8.0.orig.tar.gz $ cd ~/linux-6.8 $ patch -p1 < ~/linux_6.8.0-43.43.diff I applied your 2 patch files: $ git apply ~/0001-usb-typec-ucsi_acpi-Add-LG-Gram-quirk.patch $ git apply ~/0002-usb-typec-ucsi_acpi-Add-Victus-by-HP-Gaming-Laptop-1.patch I also hand edited ucsi.c and ucsi_acpi.c, adding in the printk statements from the kernel.org bug 217076: https://bugzilla.kernel.org/attachment.cgi?id=306314&action=diff#a/drivers/usb/typec/ucsi/ucsi_acpi.c_sec1 Finally, I ran make: $ make -C /lib/modules/`uname -r`/build M=$PWD/drivers/usb/typec/ucsi/ next I ran the following series of commands to remove the running kernel modules and insert the new debug ones. $ logger -t DEBUG "rmmod ucsi_acpi.ko"; sudo rmmod ucsi_acpi $ logger -t DEBUG "rmmod typec_ucsi"; sudo rmmod typec_ucsi $ logger -t DEBUG "insmod drivers/usb/typec/ucsi/typec_ucsi.ko"; sudo insmod drivers/usb/typec/ucsi/typec_ucsi.ko $ logger -t DEBUG "echo 'file ucsi.c +p' > /proc/dynamic_debug/control"; sudo sh -c 'echo "file ucsi.c +p" > /proc/dynamic_debug/control' $ logger -t DEBUG "insmod drivers/usb/typec/ucsi/ucsi_acpi.ko"; sudo insmod drivers/usb/typec/ucsi/ucsi_acpi.ko I then plugged in a usb-c plantronics headset, hoping to trigger anything usb-c The CPU is still through the roof! I then removed the kernel modules $ logger -t DEBUG "rmmod ucsi_acpi.ko"; sudo rmmod ucsi_acpi $ logger -t DEBUG "rmmod typec_ucsi"; sudo rmmod typec_ucsi Following this update I will attach a syslog which shows this event. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2073538 Title: kacpi_notify high cpu on interrupt gpe17 Status in linux package in Ubuntu: Incomplete Bug description: Picked up a HP laptop during July sales, and found the CPU soars to 80+ with kacpi_notify hitting GPE17. I would like some help finding the cause. Google searches were vague about masking the interrupt which did NOT help. If we can find what is calling the interrupts maybe we can better document a solution. top - 20:00:05 up 10 min, 1 user, load average: 86.24, 76.27, 42.44 Tasks: 453 total, 2 running, 451 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.1 us, 8.5 sy, 0.0 ni, 91.4 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 62040.5 total, 51595.7 free, 3166.0 used, 8146.3 buff/cache MiB Swap: 0.0 total, 0.0 free, 0.0 used. 58874.4 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 127 root 20 0 0 0 0 D 1.3 0.0 0:03.71 [kworker/11:1+kacpi_notify] 280 root 20 0 0 0 0 D 1.3 0.0 0:06.63 [kworker/5:5+kacpi_notify] 314 root 20 0 0 0 0 D 1.3 0.0 0:06.68 [kworker/5:12+kacpi_notify] ubuntu@ubuntu:~$ grep . -r /sys/firmware/acpi/interrupts/ | awk '$2 > 0' /sys/firmware/acpi/interrupts/sci: 1907 /sys/firmware/acpi/interrupts/gpe_all: 1907 /sys/firmware/acpi/interrupts/gpe17: 1907 EN enabled unmasked ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: linux-image-6.8.0-31-generic 6.8.0-31.31 ProcVersionSignature: Ubuntu 6.8.0-31.31-generic 6.8.1 Uname: Linux 6.8.0-31-generic x86_64 NonfreeKernelModules: zfs ApportVersion: 2.28.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/seq: ubuntu 2813 F.... pipewire /dev/snd/controlC1: ubuntu 2815 F.... wireplumber /dev/snd/controlC0: ubuntu 2815 F.... wireplumber /dev/snd/controlC2: ubuntu 2815 F.... wireplumber CRDA: N/A CasperMD5CheckResult: unknown CasperVersion: 1.498 CloudArchitecture: x86_64 CloudID: nocloud CloudName: unknown CloudPlatform: nocloud CloudSubPlatform: seed-dir (/var/lib/cloud/seed/nocloud) CurrentDesktop: ubuntu:GNOME Date: Thu Jul 18 19:52:46 2024 LiveMediaBuild: Ubuntu 24.04 LTS "Noble Numbat" - Release amd64 (20240424) MachineType: HP Victus by HP Gaming Laptop 15-fb2xxx ProcEnviron: LANG=C.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcFB: 0 amdgpudrmfb ProcKernelCmdLine: BOOT_IMAGE=/casper/vmlinuz --- quiet splash RelatedPackageVersions: linux-restricted-modules-6.8.0-31-generic N/A linux-backports-modules-6.8.0-31-generic N/A linux-firmware 20240318.git3b128b60-0ubuntu2 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 05/20/2024 dmi.bios.release: 15.3 dmi.bios.vendor: AMI dmi.bios.version: F.03 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 8C2F dmi.board.vendor: HP dmi.board.version: 04.14 dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.chassis.version: Chassis Version dmi.ec.firmware.release: 4.14 dmi.modalias: dmi:bvnAMI:bvrF.03:bd05/20/2024:br15.3:efr4.14:svnHP:pnVictusbyHPGamingLaptop15-fb2xxx:pvr:rvnHP:rn8C2F:rvr04.14:cvnHP:ct10:cvrChassisVersion:skuA14MNUA#ABA: dmi.product.family: 103C_5335M7 HP Victus dmi.product.name: Victus by HP Gaming Laptop 15-fb2xxx dmi.product.sku: A14MNUA#ABA dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2073538/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
