For sdma v4, there is bug caused by commit d4e869b6b5d6 ("drm/amdgpu: add ring test for page queue")' local variable ring is reused and changed, so amdgpu_ttm_set_buffer_funcs_status(adev, true) is skipped accidently. As a result, amdgpu_fill_buffer() will fail, kernel message: [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off. [ 25.260444] [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off. [ 25.260627] [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off.

README
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 Restructured Text 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.
