Resuming from suspend takes 12-14 seconds

Hi there!

I have installed OpenBSD 6.9 on my ThinkPad E495, and I have run
syspatch and fw_update to install all the necessary patches and
firmwares. I have been running it for a few weeks now, and I absolutely
love it!

Except, there is one very annoying issue.
Resuming from suspend _always_ takes 12-14 seconds at least.

Say, I press the sleep button. Within two seconds, the PC goes into
sleep. Then, I press any button on the keyboard to wake up the PC. As
soon as I press the button, the POWER LED lights up, indicating that the
hardware is up and running. But, the screen stays OFF for the next 11-13
seconds. Then, the display turns on and shows ttyC0, and after a second,
automatically switches to Xenocara.

Any idea what's causing the 11-13 second delay in the screen turning on?
How do I go about diagnosing the problem?

Also, in case it is relevant, I have noticed that these lines appear in
dmesg when I suspend and resume -

uhub0 detached
video0 detached
uvideo0 detached
uhub1 detached
iwm0: acquiring device failed
uhub0 at usb0 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1
uhub1 at usb1 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1
uvideo0 at uhub1 port 2 configuration 1 interface 0 "SunplusIT Inc
Integrated Camera" rev 2.01/54.22 addr 2
video0 at uvideo0

I presume that the first four lines are from suspending? And that the
remaining lines are from resuming?

I wondered if it could be that the delay is being caused by the failure to
acquire iwm0? (iwm0 is my Intel WiFi card)
So, I disabled my WiFi in BIOS. I also disabled USB, Camera, Microphone,
Ethernet, and the Memory Card slot. But the problem is still there!

Now, these lines appear on dmesg on suspend-resume (I don't know what
uhub0 and uhub1 are) -

uhub0 detached
uhub1 detached
uhub0 at usb0 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1
uhub1 at usb1 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1

I have no idea what is causing the delay. Any help to identify the
problem is appreciated.

Please pardon me if this is a simple mistake in my part... I am new to
OpenBSD :)

The full dmesg (with everything except Bluetooth enabled) follows -

amdgpu startup is slow.

not our fault.

Post by Subhaditya Nath
Hi there!
I have installed OpenBSD 6.9 on my ThinkPad E495, and I have run
syspatch and fw_update to install all the necessary patches and
firmwares. I have been running it for a few weeks now, and I absolutely
love it!
Except, there is one very annoying issue.
Resuming from suspend _always_ takes 12-14 seconds at least.
Say, I press the sleep button. Within two seconds, the PC goes into
sleep. Then, I press any button on the keyboard to wake up the PC. As
soon as I press the button, the POWER LED lights up, indicating that the
hardware is up and running. But, the screen stays OFF for the next 11-13
seconds. Then, the display turns on and shows ttyC0, and after a second,
automatically switches to Xenocara.
Any idea what's causing the 11-13 second delay in the screen turning on?
How do I go about diagnosing the problem?
Also, in case it is relevant, I have noticed that these lines appear in
dmesg when I suspend and resume -
uhub0 detached
video0 detached
uvideo0 detached
uhub1 detached
iwm0: acquiring device failed
uhub0 at usb0 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1
uhub1 at usb1 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1
uvideo0 at uhub1 port 2 configuration 1 interface 0 "SunplusIT Inc
Integrated Camera" rev 2.01/54.22 addr 2
video0 at uvideo0
I presume that the first four lines are from suspending? And that the
remaining lines are from resuming?
I wondered if it could be that the delay is being caused by the failure to
acquire iwm0? (iwm0 is my Intel WiFi card)
So, I disabled my WiFi in BIOS. I also disabled USB, Camera, Microphone,
Ethernet, and the Memory Card slot. But the problem is still there!
Now, these lines appear on dmesg on suspend-resume (I don't know what
uhub0 and uhub1 are) -
uhub0 detached
uhub1 detached
uhub0 at usb0 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1
uhub1 at usb1 configuration 1 interface 0 "AMD xHCI root hub" rev
3.00/1.00 addr 1
I have no idea what is causing the delay. Any help to identify the
problem is appreciated.
Please pardon me if this is a simple mistake in my part... I am new to
OpenBSD :)
The full dmesg (with everything except Bluetooth enabled) follows -

amdgpu startup is slow.
not our fault.

Oh.
You mean amdgpu(4), right?

But resuming from suspend is instantaneous in Linux...
Why is it so slow on OpenBSD?

I am sorry, but I am new to OpenBSD, and I am genuinely curious about
what might cause amdgpu startup to be so slow on OpenBSD compared to
Linux.

Oh.
You mean amdgpu(4), right?
But resuming from suspend is instantaneous in Linux...
Why is it so slow on OpenBSD?

different code.

I am sorry, but I am new to OpenBSD, and I am genuinely curious about
what might cause amdgpu startup to be so slow on OpenBSD compared to
Linux.

Oh.

So you mean that amdgpu on Linux is different than amdgpu on OpenBSD?
(ie. different code in amdgpu-linux and amdgpu-openbsd)

Or do you mean that the underlying syscalls made by amdgpu are handled
differently on Linux and OpenBSD? (ie. same code of amdgpu)

I'm just curious...

In other words, you are probably better off asking on the amdgpu(4)
mailing list:
https://lists.freedesktop.org/mailman/listinfo/amd-gfx

The link above, in fact, was copied from amdgpu(4). Other relevant
links can also be found there alongside it.

Now I understand it.

amdgpu(4) is written by the devs at freedesktop.org, and OpenBSD devs
are not involved in it. amdgpu(4) is distributed by freedesktop.org,
and OpenBSD merely includes it in the OS. So, any issues regarding
amdgpu(4) belong to the freedesktop mailing lists.

Thanks for clarifying!
