Changes
- Added support to mine Conflux (-a OCTOPUS) on AMD GPUs (Vega and newer). Fee is 2%. See tuning notes below
Fixes
- Fixed power readings of older AMD GPUs in Linux
Tuning hints for Octopus algorithm on AMD GPUs
Octopus is a very demanding algorithm - in fact we are the first implementation that allows mining it on AMD RX 6000 and 7000 cards close to their memory bandwidth. That said: start with clocks usually used for dual mining or KawPow and evolve from there or alternatively go for maximum possible core clock speed and lower it step by step until the desired efficiency is reached or performance drops too much.

Notes
- The above code is optimized for RDNA 2 & 3. RDNA 1 speeds are also reasonably good, but the cards suffer more from their low compute core count. Vega and Radeon Instinct support is experimental.
- We observed a slightly better performance on the newer Amd drivers from the last two years. We do not recommend to run this code on old drivers.
- Nvidia support for Octopus will be added next version.
