is there any way to add gfx804 kernel for sapphire pulse rx 550?
Unfortunately no. Because of toolchain restrictions, this will be hard to maintain. Maybe someday in future.
Hi, master!
How about deeponion (x13), lux(phi2) into todo list?
Thanks in advance))
X11, X13, X14 and X15 are ASIC minable, so I don't see any reason to add it into miner

What about phi2 - no plans for it right now, need some time to learn Lyra2 family algo's and difference between them.
