Hi,
I came across this code snippet at vmwgfx_kms.c:2000. The loop variable i is
never used and rects is checked again and again. Should it be something like
rects[i].x instead of rects->x? Thanks.
for (i = 0; i < arg->num_outputs; ++i) {
if (rects->x < 0 ||

We indeed have a non-trivial set of people interested in the same set of
problems and each of us has partial and maybe competing solution. I want

So I think we do have enough people interested in this and should be able
to cobble together something that does The Right Thing.

Virtual makes sense for a displaylink attached device though,
again if you were using a real driver you would just re-use whatever
output type it uses, though I'm not sure how well that w

are looking for. I recognize that it disrupts your current views/plans on
how this should be done, but I do want to work with you to find a suitable
middle ground that covers most of the possiblities.
In case you are looking at my code to follow the above-described
scenarios, please make sure y
