Revision bd13b2b874eceb4677cd26eebdc5f45cc52fa400 authored by Nicholas Kazlauskas on 01 February 2019, 14:36:59 UTC, committed by Alex Deucher on 08 April 2019, 15:33:40 UTC
[Why] If the cursor pos passed from DM is less than the plane_state->dst_rect top left corner then the unsigned cursor pos wraps around to a large positive number since cursor pos is a u32. There was an attempt to guard against this in hubp1_cursor_set_position by checking the src_x_offset and src_y_offset and offseting the cursor hotspot within hubp1_cursor_set_position. However, the cursor position itself is still being programmed incorrectly as a large value. This manifests itself visually as the cursor disappearing or containing strange artifacts near the middle of the screen on raven. [How] Don't subtract the destination rect top left corner from the pos but add it to the hotspot instead. This happens before the pos gets passed into hubp1_cursor_set_position. This achieves the same result but avoids the subtraction wrap around. With this fix the original cursor programming logic can be used again. v2: add hunk that got dropped accidently when this patch was originally committed.
