Removing an amdgpu device that still has user space references allocated
to it causes undefined behaviour. So, implement amdgpu_pci_can_remove()

Wire up the can_remove() callback, such that pci drivers can implement
their own version of it.

Currently, drivers have no mechanism to block requests to unbind
devices. However, this can cause resource leaks and leave the device in
an inconsistent state, such that rebinding the device may cause a hang
or otherwise prevent the device from being rebound. So, introduce

[Why]
While in IPS2 an access to dcn registers is not allowed.
If interrupt results in dc call, we should disable IPS.
[How]
Safeguard register access in IPS2 by disabling idle optimization
before calling dc interrupt

The issue arises when the array 'adev->vcn.vcn_config' is accessed
before checking if the index 'adev->vcn.num_vcn_inst' is within the
bounds of the array.
The fix involves moving the bounds check before the array access. This
ensures that 'adev->vcn.num_vcn_inst' is within the bounds of the

Hi Joshie,
the first patch is already on the way upstream since that is a clear bug
fix.
Sunil has setup a test system and contacted up with Friedrich to get his
hands on the test application and reproduced the problem. It looks like
that the OVERFLOW_CLEAR bit is only the tip of the

Hello Christian,
Any update on finding an upstreamable solution for this problem?
Having working hang recovery is really important for us on Steam Deck,
and it would be nice to have an upstream solution, and not carry a bunch
of patches you disagree with. :P
Thanks
