[PATCH] gpiolib: acpi: Add ignore_wake quirk for ASUS ZenBook UX425UA_UM425UA
Posted by Kivan 1 month, 1 week ago 
The ASUS ZenBook UX425UA_UM425UA (with AMD Ryzen 7 5700U SoC) fails
to stay suspended in s2idle (Modern Standby), prematurely waking
after 1-3 seconds with 0% hardware sleep achieved.

In the laptop's ACPI SSDT tables (SSDT15), GPIO Pin 24 (hex 0x18) is
defined in _AEI as ExclusiveAndWake targeting the PCIe bridge device
\_SB.PCI0.GPP3:

    GpioInt (Edge, ActiveLow, ExclusiveAndWake, PullNone, 0x0000,
             "\\_SB.GPIO", ...) { 0x0018 }

When the SoC powers down PCIe root ports into low-power states during
s2idle, an electrical edge transition triggers a spurious wake interrupt
on GPIO Pin 24. This signals the AMD GPIO controller (AMDI0030:00 / IRQ 7
via pinctrl_amd), aborting sleep across the system.

Booting with kernel parameter "gpiolib_acpi.ignore_wake=AMDI0030:00@24"
completely resolves the issue: amd_gpio reports ignoring the wakeup on
pin 24, and interrupt counts in /proc/interrupts remain at 0 during sleep
cycles, allowing uninterrupted s2idle until intentionally woken by the
user.

Add a DMI quirk entry to ignore wake events on AMDI0030:00@24 for this
system.

I thought I am going to pick this up via my tree...
But okay, not a big deal, I don't expect any conflict in that area.

Oops, sorry. If any conflict does occur let me know, I can revert it or we can
fix it in tree.

Regardless of who's tree this goes through I would like to point out
that a quirk like this really should go through a fixes branch
for the current cycle (no idea if it already is on a fixes branch,
the "applied" message does not make that clear).

It's queued for v7.4 alright.

What is connected to this GPP3?

Can you please share your acpidump somewhere?

Re: [PATCH] gpiolib: acpi: Add ignore_wake quirk for ASUS ZenBook UX425UA_UM425UA

Hi Mario,

Nothing is physically connected to GPP3. The bridge (00:02.1 /
\_SB.PCI0.GPP3) is unpopulated on this board (the ZenBook UX425UA has
no Ethernet or secondary PCIe devices there).

The DSDT seems to have leftover definitions for RTL8/RUSB on GPP3 from
a shared BIOS base, and routes GPIO pin 24 to it in _EVT, causing
phantom wake events during s2idle.

Here is the acpidump:
https://gist.github.com/vaknin/142f5cbad15958e9025cd81960114f6e

Thanks,
Kivan

Thanks.  The dump agrees with your assessment.
