Date: Tue Apr 10 01:18:25 2018 -0700
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):
1. commit 0014868b9c3c1dda1de6711cf58c3486fb422d07
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Fri Nov 2 16:12:09 2018 +0000
drm/i915: Mark pin flags as u64
2. commit 085603287452fc96376ed4888bf29f8c095d2b40
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Thu Oct 25 10:18:23 2018 +0100
drm/i915: Compare user's 64b GTT offset even on 32b
3. commit c58281056a8b26d5d9dc15c19859a7880835ef44
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Thu Oct 25 10:18:22 2018 +0100
drm/i915: Mark up GTT sizes as u64
4. commit 83b466b1dc5f0b4d33f0a901e8b00197a8f3582d
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Fri Nov 2 16:12:09 2018 +0000
drm/i915: Mark pin flags as u64
5. commit 6fc4e48f9ed46e9adff236a0c350074aafa3b7fa
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Thu Oct 25 10:18:23 2018 +0100
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.</pre>
