Hi all, Since I connected my Dell display on my Radeon R5 240 (Oland) card over DisplayPort instead of VGA, I get the following error messages logged at every boot: [drm:dce_v6_0_encoder_mode_set [amdgpu]] *ERROR* Couldn't read Speaker Allocation Data Block: -2 [drm:dce_v6_0_encoder_mode_set [amdgpu]] *ERROR* Couldn't read SADs: -2 I also see them each time the display wakes up and also on VT change. This is with kernel 5.2.9. This was also reported as bug #107825 by Paul Menzel: https://bugs.freedesktop.org/show_bug.cgi?id=107825 Error -2 is ENOENT (No such file or directory). The driver queries the display for audio-related information, while my display does not have speakers nor headset connector. I suspect that the "error" is pretty much expected in this case and the driver is being too verbose about it. Either the calling code should consider -ENOENT as a non-error (11 calling sites to fix), or the helper functions should simply return 0 when no audio-related data is available from the display (2 functions to fix, calling sites may have to be inspected too as some treat 0 as an error too, which seems incorrect to me). Option 1 seems cleaner to me, but I don't know if there could be legitimate reasons to distinguish between no audio information block from display and empty audio information from display in the future. What do you think?
