V1.8.8
- Reduced CPU usage up to ~50%, can be noticed on algos with small scratchpad
- User is now informed about tweaking status on the screen too, not just in log
- No more --gpureorder, device ordering by bus id is now the default/only display mode
- Added parameter --watchdogrounds , which controls after how many rounds will watchdog trigger
- min_rig_speed_duration default is 1 minute now, because of the new --watchdogrounds parameter
- Fixed a few cosmetical things on web stats


+ If not using 'old_mode', on weak CPU's the cpu usage could go boom on algos with small scratchpad (UPX2, Turtle). In this version i managed to lower the cpu usage up to ~50%.
This also brings a small hashrate increase for RX cards on UPX2 as a side effect Smiley

+ The default (and only) device ordering mode from now on is ascending by bus id, as it is in OverdriveNTool. Parameter --gpureorder is removed.

+ Because of some trouble with gpu/min_rig_speed watchdog and kernel precompilation on CN/R (V4), a new parameter --watchdogrounds was added, so you can control after how many check-rounds will the watchdog trigger.
The GPU crash watchdog has a fixed interval of 30 seconds = 1 round. That means it will trigger miner restart only after --watchdogrounds * 30 sec (default number of rounds is 5).
5 * 30 = 150 sec ~ 2.5 minutes. If gpu crashes and can't recover for 2.5 minutes, the miner will trigger the restart action.

min_rig_speed parameter is also affected by --watchdogrounds from now on. The 'min_rig_speed_duration' parameter default value is now 60 sec, this is the value as the above for the gpu crash watchdog, except that you can change the value of this to anything >= 30 sec.
Taking the default value of 60 seconds and 5 rounds, it is 5 * 60 = 300 sec = 5 minute, that means if for 5 minutes the 'min_rig_speed' < total hashing speed, then it will trigger miner restart.


I have an issue, my computer cashes because now SRB tries to use the Vega cores inside the Ryzen 2400G to mine, how could I disable the APU in your miner ?

Thanks
