Hi, 1, You can try 3.16 from master branch here: http://dev.lemote.com/cgit/linux-official.git/ 2, Since 3.14, radeon cannot support non-firmware display. This is confirmed by drm maintainers.

I met 2 major problems: 1. On the Lemote 6100 and Yeeloong 8133, load command hangs PMON> load (wd0,0)/vmlinux-3.16-3-loongson-3 Loading file: (wd0,0)/vmlinux-3.16-3-loongson-3 (elf64) 0x80200000/9171584 + 0x80abf280/34201152(z) It also hangs on the dev board from Lemote. While it can boot on dev boards from Loongson. 3.15 kernel works fine on both boards. 2. If without radeon non-free firmware in initrd/vmlinux, the screen can display nothing. It makes us difficult to patch debian-install to support Loongson 3. A automatic fallback may be needed when nonfree firmware is not available. -- YunQiang Su
