Hi Noralf,

since you're here, I'll just hijack the discussion to ask something only 
semi-related.

IIRC the gud driver doesn't update the display immediately during atomic 
commits. Instead, it instructs a helper thread to do the update. What's 
the rational behind this design? Is that something we should adopt for 
other drivers that operate over slow buses (USB, I2C, etc)? Would this 
be relevant for the ssd1307 driver?

Best regards
Thomas
