    clover commit #3906 says it fixed the polaris booting problem,but it still hanged on my system,can someone confirm my testing?

    did you actually read the guide?it is indeed for 12.1 no,just using igpu booting into clover interface, then unplugged it and plugged the into 480's port,hit enter to booting the system,there's no any display output until login screen you needs do this every time when booting

    guide here: https://www.theitsage.com/install-radeon-rx-480-gpu-macos-sierra/ keeping in mind doing this on non-mac will results in hang during booting the only way getting polaris accelerated on non mac was booting with igpu, you could switch to your 480 later

    i though it have nothing to do with opengl performance,its just provide a channel for IGP video output indeed its possible to collaborate the IGP and discrete GPU, but it required to be supported by both GPU, like AMD's hybrid graphics

    no,there are indeed something wrong in device list,check out the string for 280 { 0x6798, 0x00000000, CHIP_FAMILY_TAHITI, "AMD Radeon HD 7970X/8970/R9 280X", kFutomaki }, and here for 480: { 0x67DF, 0x00000000, CHIP_FAMILY_ELLESMERE, "AMD Radeon RX480", kNull }, 280 string was right which framebuffer for tahiti chips is futomaki, where all framebuffer setting for polaris chips are "Null" @Gigamaxx i believe we define working as the system could be booted with discrete gpu alone without the igpu, no needing for edit kext files,basic functions like Quartz and opengl could be rendered with hard acceleration,booting with igpu definitely give you a partially accelerated system,but first two requirements are not satisfied currently,don't forget many people using Xeon E5 or X99 mobo and even you got a accelerated system, the drivers tend to crash when under high load or complex operations,just trying enable opencl in FCPX

    taking some time checking the source code of clover, all code regard AMD gpu initializing resident in the file ati.h and ati.c,i have found out theres some problem maybe the reason why polaris failed to initialize during booting 1. Framebuffer list did not include polaris framebuffers 2. in device list,the framebuffer setting for rx 480 is "ELLESMERE",which did not exist in macos driver 3.no mention about rx 470 at all i know nothing about C language,if someone could provide more insight into these two files, we would great appreciated

    strictly says 470/480 aren't working, you would got a bootable system without any acceleration or kernel panic when trying add device id into kexts
