P.S. Sorry for second pull request, first time selected wrong branch

[tupieurods]

Can i get a list of required fixes in my commits? As i understand first thing: return WATCHDOG_SICK_TIME to 120.

[tupieurods]

What should i fix next?

[mrbrdo]

It looks much better now.
I don't understand the use case of the exit frequencies ("idle"). Why is this useful, do you expect long periods of time where the GPUs are idling? I don't see why this would happen.

[tupieurods]

Internet crash, for example. Or user configured just one/two pools for mining and it's offline.

[mrbrdo]

And the point is just to save power?

[tupieurods]

Yes. Actually, i don't care about electricity, because i pay 0.04$ per kW/h. But someone pays more, a lot of more.

[mrbrdo]

I don't think this is the right approach to this. We can simply disable all devices. Perhaps it's also necessary to shutdown threads, but I don't think so. Is this even an actual problem, do the devices actually work on anything if there is no new work from pool? They don't just idle?

[tupieurods]

No, they don't work. Tried to unplug internet connection: clocks dropped, gpu usage: 0.

[mrbrdo]

so then there is no need for that change?

[tupieurods]

I'm using sgminer version with this fix. I will try to run version without.

[tupieurods]

Same behavior. Maybe depends from driver, looks like we don't need it. Should i remove it or you will remove it in merger process?
Also i have question about git usage. Currently my fork isn't updated to this repo(x13mod added), should i do merge in my fork or rebase?

[mrbrdo]

I'll take care of it in the evening.

Normally you would do a rebase yeah, and force push that. Similarly you could rebase and update existing commits if needed, instead of adding new commits.

[tupieurods]

Sorry, did some experiments with my git and as result i lost all your comments in commits. I'm so sorry.
Restored some of them(i lost only my answers, because github didn't mail them to me):
_[sgminer] show-coindiff option added_
mrbrdo: you are hardcoding values that are not hardcoded anymore. that's the whole point of this branch
mrbrdo:man.. there is numerator in algorithm struct... see for example https://github.com/tupieurods/sgminer/blob/v5_0/sgminer.c#L4136
Also, please rename this new function to get_work_blockdiff and use it in set_blockdiff instead of having the same code 2 times.
_[sgminer] Extend time to sick state_
mrbrdo:How does this affect Scrypt and other coins? Why is this necessary in the first place?
mrbrdo:It could indicate some other issue. Also some user is talking about stratum issues with nicehash but this has been fixed in this build. Also just because this was a problem with the original build doesn't mean it's necessarily a problem with this one. Unless we are sure what is going on I am not happy with choosing arbitrary values to fix something.
mrbrdo:good catch, it seems it should be 120 and say 2 minutes.

[mrbrdo]

Yeah no worries, this is normal if you rebase and force push...

[mrbrdo]

I will merge all except GPU idle thing. Also next time please base your stuff on v5_0 branch instead of master.
