Is this something you can look at @nerdralph?
This would be helpful to have. I've used the --opencl-devices option for testing individual GPUs, but per-GPU hashrate display would be better. I've only just got comfortable with the stratum code, so it might take me a while to figure out how the hashrate calculation works. Will give it a shot though.
Didn't turn out to be that hard to do; just pushed the changes.
ethminer 28626 15099 15099 20761 15099 21076 = 115762Khs [A54+0:R0+0:F0]
I went with Khs instead of Mhs because:
Great! I still prefer MH/s though, because that's what most people use. Imo the extra digit is less significant than the amount of questions you have to answer to people than can't divide by 1000 ;-)
still went with MH/s, but thanks for the work!
