 |
|
Hello,
I have an ASUS VivoBook M1605 laptop (https://www.telia.lt/prekes/kompiuterine-iranga/nesiojami-kompiuteriai/asus/asus-vivobook-m1605-16-ryz5-8gb-512gb) and this laptop has a keyboard backlight that works on the dist kernel, but not my custom one. Currently, I am working on my custom kernel config after running the dist one as I had some free time and I'm stuck on the backlight part and am unsure what to do about it. I've looked up what could it be and it feels like I've tried everything out, but yet - no luck :/
The backlight is located at `/sys/class/leds/asus::kbd_backlight/` on the dist kernel if that helps, but generally it seems weird. I've enabled WMI, ASUS laptop extras, compiled stuff as modules, etc and I can't find the combination of configurations that work. sadly, so I thought I'd ask all of you if y'all know anything about it.
My current kernel config: https://0x0.st/XZdZ.txt (Sorry, kind of a mess at this moment, it's a draft right now. I just yesterday switched back to Gentoo for the second time this year).
I hope we can figure something out :) & thanks for answers in advance!

I also need the output of dmesg (after a system start).
Perhaps you would like to read this in the meantime:
https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_Configuring_Kernel_Version_6.6
| Code: | 1.
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
2.
CONFIG_X86_INTEL_PSTATE=y
# CONFIG_X86_PCC_CPUFREQ is not set
# CONFIG_X86_AMD_PSTATE is not set
# CONFIG_X86_AMD_PSTATE_UT is not set
# CONFIG_X86_ACPI_CPUFREQ is not set
3.
# CONFIG_IOMMU_SUPPORT is not set |
1. Not related to your problem, but a performance problem; please see PART3 of my tutorial
2. You really should have at least ACPI_CPUFREQ; for a newer AMD machine of course AMD_PSTATE is better (enable them all)
3. Maybe related to your problem; you really should have enabled it in any case; please see PART2 of my tutorial
--------------------------
(Own notes for later
CONFIG_NR_CPUS=12
CONFIG_AMD_SFH_HID is not set
# CONFIG_SPI is not set
-> ?? CONFIG_SPI_DESIGNWARE )

Hi!! Sorry for the late response.
Dmesg output (trimmed): https://0x0.st/XZ50.txt
I'll fix up the config when I'm back home
and uh
- CONFIG_NR_CPUS: AMD Ryzen 5 7530U (12) @ 4.366GHz - I just set it to the minimum possible
- CONFIG_SPI_DESIGNWARE is for my touchpad: https://forums.gentoo.org/viewtopic-t-1167132-highlight-.html

I also asked about your dmesg because I already suspected this:
| Code: | [ 0.024605] smpboot: 16 Processors exceeds NR_CPUS limit of 12
[ 0.024606] smpboot: Allowing 12 CPUs, 0 hotplug CPUs |
I've had this happen before with AMD CPUs (and I don't know why they're so weird) and it's always caused strange problems. So, change it to 16. (See also in PART 4 of my tutorial)
No, you do NOT have SPI enabled. I made the question mark at SPI_DESIGNWARE because I saw that you have it enabled ... for the touchpad: CONFIG_I2C_DESIGNWARE_CORE=y. But you have not activated the PCI controller itself:
| Code: | # CONFIG_PCIE_DW_PLAT_HOST is not set
# end of DesignWare-based PCIe controllers |
So I would ask you to check if you really have it. If so, please enable the controller AND then SPI with SPI_DESIGNWARE.
The next question I have is: Have you ever booted with our GentooLiveCD (or UbuntuCD) and checked with "lsmod" which modules are loaded? This is usually very informative.
Please change your configuration as described and if it still does not work, I need the new .config and the - complete - dmesg again.
