Comment 21 for bug 1815172

Most likely mesa were broken with commit:

    i965: Allocate VMA in userspace for full-PPGTT systems.

In the kernel (especially 32-bit) it requires such commits (all of them are present from kernel 4.19.3):

    drm/i915: Mark pin flags as u64

2. commit 085603287452fc96376ed4888bf29f8c095d2b40
Author: Chris Wilson <email address hidden>

5. commit 6fc4e48f9ed46e9adff236a0c350074aafa3b7fa

    drm/i915: Compare user's 64b GTT offset even on 32b

So its question to Chris if he could propagate such commits into kernel. Because looks like even 4.15 is commonly used still.
