From d8ee89c6393d78b52b42fe0f188fe382fa8fc162 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 7 Oct 2015 17:07:01 -0400 Subject: [PATCH] drm/amdgpu/dce11: Use cursor_set2 hook for enabling / disabling the HW cursor MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The cursor_set2 hook provides the cursor hotspot position within the cursor image. When the hotspot position changes, we can adjust the cursor position such that the hotspot doesn't move on the screen. This prevents the cursor from appearing to intermittently jump around on the screen when the position of the hotspot within the cursor image changes.
