I think you also want to check that the x,y src are at (0, 0).

Hm, I was thinking that is handled by CAN_POSITION, but that really is all about src vs. dst in plane coordinates.

I guess at that point its almost nicer to create a drm_rect for fb and use drm_rect_equals.

Plus needs kerneldoc.

But aside from the details, I like.

To improve readability and make it easier to add further optional checks replace the boolean parameters with a single flag bitfield as parameter of drm_atomic_helper_check_plane_state.

The regular call sites have been converted using a simple coccinelle patch.

virtual patch

Looks reasonable, but needs kerneldoc. For that either do a list in the kerneldoc for drm_atomic_helper_check_plane_state, or make the flags an enum (still setting the value for each explicitly), and then kerneldoc that with a link from the function to that.

The kerneldoc updates for drm_atomic_helper_check_plane_state() should cover it mostly. I did miss update it in patch 2, so will fix that.

I thought to keep it similar to drm_atomic_helper_commit_planes() and use #defines as well as describing the flags in the function kerneldoc. Should I make it a list instead?

A kerneldoc/rst list within the function should work well too and look pretty. Whatever you prefer, just make sure the html output isn't broken somehow. -Daniel

This implements what has been discussed in the thread of the patch "drm: mxsfb: check framebuffer pitch": https://lkml.org/lkml/2020/9/8/1342

Before sending it out to all maintainers I wanted to get conformation if the general approach is fine.

I think in some places there should be another linebreak for the flags, but this is what coccinelle gives me. Not sure if I should manually fix those places...
