[Bug 217076] Charging causes high CPU usage on LG Gram laptops series Z90Q
https://bugzilla.kernel.org/show_bug.cgi?id=217076 --- Comment #59 from Diogo Ivo (diogo@tecnico.ulisboa.pt) --- Hi Ralph, Thank you for trying the instructions. You can safely ignore the BTF related stuff, don't worry about it :). Do you have any newer kernels pre-built that you can try running on your system? -- You may reply to this email to add a comment.

https://bugzilla.kernel.org/show_bug.cgi?id=217076 --- Comment #58 from Ralph Martin (ra...@cs.cf.ac.uk) --- Hi Diogo When I try to compile the modules following your instructions, I got Skipping BTF generation for /home/ralph/Downloads/linux-6.9.1/drivers/usb/typec/ucsi/ucsi_acpi.ko due to unavailability of vmlinux It was not clear if that was essential or not. I tried to fix this up, but after copying `/sys/kernel/btf/vmlinux` to corresponding position and with `dwarves` installed, building the kernel module throws an error: `/bin/sh: 1: ./tools/bpf/resolve_btfids/resolve_btfids: not found`. I see Bug#1027306: mentions this issue. I am getting further from trying out your fix it seems, rather than closer... -- You may reply to this email to add a comment.

https://bugzilla.kernel.org/show_bug.cgi?id=217076 --- Comment #57 from Ralph Martin (ra...@cs.cf.ac.uk) --- Hi Diogo I followed your instructions (I am using the current testing kernel 6.7.12), building the module with the 6.9.1 sources, disabling safe boot, and got insmod: ERROR: could not insert module drivers/usb/typec/ucsi/typec_ucsi.ko: Unknown symbol in module insmod: ERROR: could not insert module drivers/usb/typec/ucsi/ucsi_acpi.ko: Unknown symbol in module when trying to insert the compiled modules. (ucsi_acpi is blacklisted at boot, but that does not sound like it is the problem so it was not unexpected that I got the following when trying to unload the existing modules rmmod: ERROR: Module ucsi_acpi is not currently loaded rmmod: ERROR: Module typec_ucsi is not currently loaded Happy to try again if there is something else I can do. Perhaps I really need to build a new kernel - time I learnt how to do that? -- You may reply to this email to add a comment.
