The cursor plane also supports 180 degree rotation. Add a new "cursor-rotation" property on the crtc which controls this.
Unlike sprites, the cursor has a fixed size, so if you have a small cursor image with the rest of the bo filled by transparent pixels, simply flipping the rotation property will cause the visible part of the cursor to shift. This is something to keep in mind when using cursor rotation.
By flipping you meant setting 180 degree rotation?
Yes.
Don't we have to adjust the cursor base as well to the lower right corner apart from setting the control bit?
No, the hardware does that automagically. Hmm. Except on gen4 apparently. Looks like I need to test on gen4, and fix it if it's really the case.
