drm/amdgpu: revert "Add autodump debugfs node for gpu reset v8"

2021-11-06T13:11:29+00:00

commit c8365dbda056578eebe164bf110816b1a39b4b7f upstream.

This reverts commit 728e7e0cd61899208e924472b9e641dbeb0775c4.

Further discussion reveals that this feature is severely broken
and needs to be reverted ASAP.

GPU reset can never be delayed by userspace even for debugging or
otherwise we can run into in kernel deadlocks.

drm/amdgpu: handle the case of pci_channel_io_frozen only in amdgpu_pci_resume

2021-10-13T07:41:58+00:00

[ Upstream commit 248b061689a40f4fed05252ee2c89f87cf26d7d8 ]

In current code, when a PCI error state pci_channel_io_normal is detectd,
it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI
driver will continue the execution of PCI resume callback report_resume by
pci_walk_bridge, and the callback will go into amdgpu_pci_resume
finally, where write lock is releasd unconditionally without acquiring
such lock first. In this case, a deadlock will happen when other threads
start to acquire the read lock.

To fix this, add a member in amdgpu_device strucutre to cache
pci_channel_state, and only continue the execution in amdgpu_pci_resume
when it's pci_channel_io_frozen.

They are global ACPI methods, so maybe the structures
