I have just finished a fresh install of Debian 9 (Stretch) on my HP Pavilion dm3-1130us and I noticed an error message during boot up.
[ 18.670958] [drm:radeon_pci_probe [radeon]] *ERROR* radeon kernel modesetting for R600 or later requires firmware-amd-graphics.

# apt-cache search firmware-amd-graphics
firmware-amd-graphics - Binary firmware for AMD/ATI graphics chips

# apt-get install firmware-amd-graphics
Setting up firmware-amd-graphics (20161130-3) ...
After rebooting, no more ERROR message shows up.
