Subject: Re: [PATCH 0/6] drm: Add mouse cursor hotspot support to atomic KMS

Hi,
Please, read this thread:
https://lists.freedesktop.org/archives/dri-devel/2020-March/thread.html#259615
It has a lot of information about the pitfalls of cursor hotspot and
other things done by VM software.
In particular: since the driver will ignore the KMS cursor plane
position set by user-space, I don't think it's okay to just expose
without opt-in from user-space (e.g. with a DRM_CLIENT_CAP).
cc wayland-devel and Pekka for user-space feedback.

Can you elaborate? I'm not sure I understand what you mean here.
Thanks,
Simon
