Re: [PATCH] drm/omap: gem: Fix tearing with BO_TILED

* Tony Lindgren tony@atomide.com [191220 16:57]:

Looking around what might affect BO_TILED, I noticed Matthijs had this change in his earlier pyra tiler patches. The earlier patch "XXX omapdrm: force tiled buffers to be pinned and page-aligned" has no commit log though, so I'm not sure what other issues this might fix.

..

Matthijs, do you have some more info to add to the description?

Also, I'm wondering if this change makes sense alone without the pinning changes for a fix, or if also the pinning changes are needed.

For reference, the original related patch(es) are available at [0] below.

Regards,

Tony
