2. the installation comes from https://wiki.debian.org/AtiHowTo
Installation
The following procedure will install the open source display driver
packages, DRI modules (for 3D acceleration) and driver firmware/microcode:
1)Add "contrib" and "non-free" components to /etc/apt/sources.list,
for example:
# Debian 8 "Jessie"
deb http://http.debian.net/debian/ jessie main contrib non-free
2)Update the list of available packages:
# apt-get update
3)Install the firmware-linux-nonfree, libgl1-mesa-dri and
xserver-xorg-video-ati packages:
# apt-get install firmware-linux-nonfree libgl1-mesa-dri
xserver-xorg-video-ati
4)Restart your system to load GPU device firmware.
3. check the output, it successes!

glxinfo | grep rendering
direct rendering: Yes
5. I use "glxgears -info" to test the performance. However ,the
performance is so bad ! It seems no ati driver at all!
375 frames in 5.0 seconds = 74.986 FPS
300 frames in 5.0 seconds = 59.857 FPS
300 frames in 5.0 seconds = 59.855 FPS
300 frames in 5.0 seconds = 59.854 FPS
6. besides, I found some output I don't understand!
"dmesg | grep VGA" show a Firmware Bug , what's meaning of this output?
