I knew it! Could you tell engineers at AMD that we need GDS both on Windows and Linux?
This is such a waste of time and energy...
Not at all...your implementation will work just fine under linux, and im pretty sure the majority of miners (at least people with more than 1 or 2 cards) are on linux anyways.
I mine on Windows 10, 7 rigs. Me and 3 friends over 100 cards. Easier to switch coins, the RX cards don't support undervolting and such under Linux, or BIOS flashing, so Linux is less profitable by ~15%. Driver setup is a lot easier. I dual mining Eth/Dcr right now, ZEC less profit unless you have Nvidia cards. I can get $30/month/card (after power costs), or $20/month/card for ZEC. Zec mining was fun until good Nvidia miners were made, now I only mine with a few 1060s.
Bios flashing is supported under Linux, including Polaris cards. The atiflash variant that supports this was leaked quite some time ago. :-)
