Bug ID: 214921
Summary: amdgpu hangs HP Laptop on shutdown
Product: Drivers
Version: 2.5
Kernel Version: 5.15
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: spasswolf@web.de
Regression: No
Commit bf756fb833cbe8c6881c964f09db718bade6e591 leads to an improper shutdown,
i.e. the System does not switch off and has to be powered off by pressing the
power button for a long time. The problem seems to occur relatively late in the
shutdown as it leaves no trace in logfiles.
It also does not fix hangs on suspension on this Laptop.
Reverting this commit in 5.15 leads to working shutdown again while
resuming from suspension still does not work.

It turns out that ressuming from suspend has been broken a long time on the
above hardware. The last Kernel where it works is 5.12.
The first commit where resuming from suspend leads to screen corruption is

Spasswolf's comment doesn't seem in any way related to this bug report. I
presume it was filed against the wrong bug!
I can confirm on my setup, HP laptop with an AMD "Stoney" chipset, on kernel
5.15.0 the system doesn't shutdown when you use KDE power menu "shutdown", nor
if you issue the "halt" or "poweroff" commands, nor "shutdown -P now".
The keyboard is dead, so Ctl-Alt-Del doesn't reboot, all that's left is holding
the power button down.
Behaviour was correct on kernel 5.14 (at least, up to 5.14.14).

Shutdown still hangs with linux-5.15.1.
This fixes the shutdown issue for me:

--- Comment #4 from spasswolf@web.de ---
This still bug is still present in the 5.15.0-next-20211112 where it breaks
suspend:
static int uvd_v6_0_suspend(void *handle)
{
int r;
struct amdgpu_device *adev = (struct amdgpu_device *)handle;
/*
* Proper cleanups before halting the HW engine:
* - cancel the delayed idle work
* - enable powergating
* - enable clockgating
* - disable dpm
*
* TODO: to align with the VCN implementation, move the
* jobs for clockgating/powergating/dpm setting to
* ->set_powergating_state().
*/
#if 0
cancel_delayed_work_sync(&adev->uvd.idle_work);
if (adev->pm.dpm_enabled) {
amdgpu_dpm_enable_uvd(adev, false);
} else {
amdgpu_asic_set_uvd_clocks(adev, 0, 0);
/* shutdown the UVD block */
amdgpu_device_ip_set_powergating_state(adev,
AMD_IP_BLOCK_TYPE_UVD,
AMD_PG_STATE_GATE);
amdgpu_device_ip_set_clockgating_state(adev,
AMD_IP_BLOCK_TYPE_UVD,
AMD_CG_STATE_GATE);
}
#endif
r = uvd_v6_0_hw_fini(adev);
if (r)
return r;
return amdgpu_uvd_suspend(adev);
}
This makes suspend work again.

Tested the patch with linux-5.15.2, linux-next-20211115 and linux-5.16-rc1. It
solves the hang on suspend (or shutdown) problem in all cases but resuming from
suspend is still broken on linux-5.15.2 when the IOMMU is missing:

Kernel 5.15.5 (which IIUC contains the patch or equivalent) works for me.
