Hi,
With Kernel v5.15 -> v6.1 upgradation, I have noticed that, now consecutive Plane IDs values are incremented by 2 each time. i.e. 34,36,38. In kernel v5.15, it was incremented by 1. i.e. 34,35,36...
I attached modetest log with kernel v6.1.
Is this change expected with new Kernel v6.1 ? If Yes, can you please elaborate the requirement/change.
Best regards,
Sunil Vaghela

This kind of header may deter some people from replying on mailing

As far as I understand, DRM object IDs are not part of the DRM ABI and
can thus change at any time, between releases or even between boots.
Userspace should not rely on any object having a specific ID.
As for why the IDs are not contiguous anymore, I believe that because of
the blob create by the call to create_in_format_blob() at the end of the
__drm_universal_plane_init() function. Blobs are DRM objects, so they're
assigned an ID.
