[Bug ?] Radeon driver won't load with mobility HD 3450 (RV620/M82)

YosheE · 1 September 2017 16:12

Hi there !

I’ve got a problem with my eeeBox B206 (Atom N270 1.6, 2Gb, mobility HD3450 RV620/M82). I post here before opening an issue on GitHub.

When I launch the live ditrib, I get a black screen, no flower.

What I did :

live nosplash tty retroarch=0 and switched to console
launch manually retroarch -v : KMS says “couldn’t find a suitable DRM device”
lspci -nnk shows the ATI HD3450 but no kernel module loaded (“radeon” should be loaded I suppose ?)

I tried with 2.0 and 2.1 RC4, i686 of course.

According to the arch linux wiki, this old chip should work with the open source ATI driver.

I hope I gave all needed information

Hi,

Please provide the complete log of Lakka system and graphic card logs and the output of

for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done

Strange it doesn’t find drm device…

Thank you.

Indeed it seems that drm device is not there.

Is it possible to boot with in the boot prompt

live drm.debug=0x1e log_buf_len=1M

then get the output of dmesg ?

Thank you.

I can provide the full dmesg output if you like, but not sure that it will be helpful

Note that I just tried to boot a Mint Xfce without problem, dmesg log is the same but firmware loads correctly and drm finds outputs etc, graphical mode works well. Hope this helps

gouchi · 1 September 2017 22:52

It seems we didn’t enable the firmware for i386 as it doesn’t find R600_rlc.bin.

We will have to enable it.
