AMD yayamba kale ntchito pa madalaivala ake amtsogolo a Navi-based video makadi a Linux-based operating systems. Chida chodziwika bwino Phoronix adapeza zambiri m'mizere yatsopano ya madalaivala a AMD omwe Navi GPUs adzagwiritsabe ntchito zomangamanga zakale za GCN.
Codename "GFX1010" idapezeka kumbuyo kwa AMDGPU LLVM. Ili ndi dzina la codename la Navi GPUs, monga ma Vega GPU apano amatchedwa "GFX900". Ndipo kugwiritsa ntchito kamangidwe ka GCN kumawonetsedwa ndi mizere iyi:
- EF_AMDGPU_MACH_AMDGCN_LAST =
- EF_AMDGPU_MACH_AMDGCN_GFX1010
Monga taonera Phoronix, kuthandizira kwathunthu kwa Navi sikutheka kukhazikitsidwa mu Linux 5.2 kernel yotsatira, ndipo mwina kuchedwa mpaka kutulutsidwa kwa Linux 5.3 kernel. Pakadali pano, kutulutsidwa kwa Linux kernel 5.3 yokhazikika kukukonzekera Seputembala. Mpaka nthawiyo, ogwiritsa ntchito a Linux angafunike kugwiritsa ntchito ma hacks ndi zidule kuti ma Navi GPU atsopano agwire bwino ntchito. Ngati, zowonadi, makhadi amakanema ozikidwa pa Navi atulukadi chilimwe chino, monga momwe amayembekezera kale.
Chosangalatsa ndichakuti magwero osiyanasiyana adawonetsa kale kuti Navi ikhala mawonekedwe atsopano, osati mtundu wina wa GCN. Izi zitha kutanthauza kuti ma GPU atsopano amatha kudutsa ma processor a 4096 pa malire a kufa omwe amapangidwa mu GCN. Komabe, monga mukuonera, izi siziri choncho. Tikumbukire kuti mtundu woyamba wa zomangamanga za GCN udapangidwa kale m'masiku a 28-nm AMD graphics processors mu makadi a kanema a Radeon 7000. Chifukwa chake, sizoyenera kwambiri tchipisi 7-nm, osati chifukwa cha kuchepetsa kuchuluka kwa ma processor stream.
