From cf388c0da8e978ed766b975ceccbf699e98bd476 Mon Sep 17 00:00:00 2001 From: Arindam Nath Date: Mon, 9 Jan 2017 11:50:27 +0530 Subject: [PATCH] drm/amd/display: fix cursor disappearing after resume Since during suspend, the cursor registers are cleared, once the system resumes back, the cursor remains disabled. cursor_set_attributes() only sets the cursor attributes along with cursor size and surface address, but does not enable the cursor back on. We need to save the current cursor location so that we can resume back to the same location. This is done in dm_crtc_cursor_move(), where we save the current cursor location into cursor_x and cursor_y. Later during resume we use these same values to set the cursor position along with cursor attributes.
