 |
|
Hi! I'm using Gentoo on a Laptop. However, after suspending, sometimes it wakes up unexpectedly. I found that closing and opening the lid seems to cause wakeups. My lid isn't recognized as a lid, so modifying systemd config didn't work:
| Code: |
➜ ~ cat /proc/acpi/wakeup
Device S-state Status Sysfs node
GP11 S4 *disabled
SWUS S4 *disabled
GP12 S4 *disabled
SWUS S4 *disabled
XHC0 S4 *enabled pci:0000:07:00.3
XHC1 S4 *enabled pci:0000:07:00.4
XHC2 S4 *disabled pci:0000:09:00.0
XHC3 S4 *enabled pci:0000:09:00.3
XHC4 S4 *enabled pci:0000:09:00.4

GPP6 S0 *enabled pci:0000:00:02.2
GPP0 S4 *enabled pci:0000:00:01.1

In dmesg, while I already have detailed logging enabled
| Code: |
➜ ~ cat /proc/cmdline
BOOT_IMAGE=/kernel-6.10.9-gentoo root=/dev/mapper/vg0-gentoo--rootvol ro root=UUID=778ffb43-269a-4ac3-8786-ccddcfbe8140 rd.luks.uuid=b02398b6-9c80-4ea2-a188-76d6c3fc2a3b rd.luks.uuid=188c0d5e-4344-42cd-9b99-b9a581fab427 rd.luks.options=discard,cache_keyring rd.lvm.vg=vg0 atkbd.reset iommu=pt amd_iommu=on pcie_acs_override=downstream,multifunction acpi.debug_layer=0x00200000 acpi.debug_level=0x02 loglevel=8

I only see some generic info, without detail of what event from what device triggered the wakeup:

How can I track down the issue? Thanks! |

Do you have kernel support for ACPI and related features?
For example, I can see this on my laptop: | Code: | $ grep . /sys/bus/acpi/drivers/button/*:00/input/input*/name
/sys/bus/acpi/drivers/button/LNXPWRBN:00/input/input2/name:Power Button
/sys/bus/acpi/drivers/button/PNP0C0D:00/input/input1/name:Lid Switch
/sys/bus/acpi/drivers/button/PNP0C0E:00/input/input0/name:Sleep Button |
Sleep states were also messed with at the hardware level some time ago. If I recall correctly, newer hardware only supports some sort of sleep state, not hibernation. I believe this keeps the management engines of the processor running, so there's a chance it might not be an event that you can block.

Yes, I do have ACPI support enabled.

I don't know what systemd does, but since Linux can see the hardware, it seems like it should be configurable. If I didn't misunderstand, systemd subsumed udev, so I wonder if a udev rule could be created. That is if it isn't something else causing the state change.

Yeah, I'm considering if I can confirm the event causing wakeup first before configuring. |

I think I've disabled all of them, however it is still not working. |

I presume you've tried searching for anything related to your specific laptop.
The only other thing that comes to mind would be something in the BIOS.

|
I didn't find much on that earlier other than there being no official Linux support. I wonder if there might be other parts of the system which are unsupported or at least not supported well.

I'm confused. In order for Linux to enter suspension, it needs to react to some kind of signal, which should be logged in any case. |

Right. So it's about finding out what that is. If it should be logged and isn't, what is responsible for that?
My question about the BIOS was whether or not it had any settings related to power management, ACPI, or the functionality of any related buttons, such as the lid or power button.
Related is that laptops are known to be "odd" with varying degrees of support available for them. The log you posted referenced two items (_SB.ACDC.RTAC and _SB.PEP._DSM) reporting errors, and at least one lacks (or lacked) in-kernel support. Might there be other parts of the laptop that are unsupported or poorly supported?
Given that the standard method of telling systemd to do something with the lid isn't working, that suggests either something lower level with systemd needs to be configured for this hardware, or that the lack of logging could be related to a lack of support / poor support.
So are there any reports of this laptop working well with Linux, or are there reports of things known to not work, .etc.
The Gentoo guide on Suspend and hibernate references a debugging document at kenrel.org, Debugging hibernation and suspend. Maybe that has something useful.
