The main issue is that while the init is called by the display side, shared by i915 and xe, the cleanup is called by a non-shared code path. Fixing that will be done as a separate commit.

The construct allocating only parts of the vma structure when the userptr part is not needed is very fragile. A developer could add additional fields below the userptr part, and the code could easily attempt to access the userptr part even if its not persent. So introduce xe_userptr_vma which subclasses struct xe_vma the proper way, and accordingly modify a couple of interfaces. This should also help if adding userptr helpers to drm_gpuvm. v2: - Fix documentation of to_userptr_vma() (Matthew Brost) - Fix allocation and freeing of vmas to clearer distinguish between the types.

xe_assert() is intended to be used only for "impossible" situations that should never be hit (and if they are hit it means there's a driver bug somewhere); assertions are only compiled into debug builds. Although we expect jobs submitted by the kernel to be well-behaved and run without error, timeouts are a legitimate possibility for reasons beyond our control (bad firmware, flaky hardware, etc.). We should use a real WARN if we encounter these, even for non-debug builds, to ensure the issue is being properly highlighted in bug reports and such. Also give the WARNs more human-readable messages and move them below the general notice-level message that gets printed for any kind of timeout to make the errors a bit more understandable. v2: - Convert the VM / exec_queue_killed assertion as well.
