Ce Sun ff2c7994e8 drm/amdgpu: Effective health check before reset 
[ Upstream commit da46735229 ]

Move amdgpu_device_health_check into amdgpu_device_gpu_recover to
ensure that if the device is present can be checked before reset

The reason is:
1.During the dpc event, the device where the dpc event occurs is not
present on the bus
2.When both dpc event and ATHUB event occur simultaneously,the dpc thread
holds the reset domain lock when detecting error,and the gpu recover thread
acquires the hive lock.The device is simultaneously in the states of
amdgpu_ras_in_recovery and occurs_dpc,so gpu recover thread will not go to
amdgpu_device_health_check.It waits for the reset domain lock held by the
dpc thread, but dpc thread has not released the reset domain lock.In the dpc
callback slot_reset,to obtain the hive lock, the hive lock is held by the
gpu recover thread at this time.So a deadlock occurred

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
