Hi,
Currently omapdrm supports TILER rotation only, which excludes omap3
and earlier SoCs. I have the hardware (N900/N950), time and will to
implement VRFB rotation support in omapdrm driver, however, I'll
appreciate some hints. Or, if there is already something ready, please
point me to it so I can take it from where it is.
Besides partially reverting 517a8a9564c0dea98e6d4e2c7f0fe4cbb9b8c9ba
and copying VRFB code from omapfb, is there anything else I shall take
in consideration? Or, VRFB driver should not be a part of omapdrm, but
a standalone one?
We already have DMM driver in the omapdrm module, and I think VRFB fits
along just fine. I don't think there ever has been any other users for
VRFB than DSS, and as it's such an old IP, I don't think there ever will.
I don't have any particular hints in mind.
Do you have omap4/5 so you can test that DMM still works after your changes?
