AMD yakatotanga basa kune vatyairi kune ramangwana reNavi-based vhidhiyo makadhi eLinux-based masisitimu anoshanda. Iyo inozivikanwa sosi Phoronix yakawana ruzivo mumitsara mitsva ye AMD driver kodhi iyo Navi GPUs icharamba ichishandisa yakanaka yekare GCN yekuvaka.
Iyo codename "GFX1010" yakawanikwa mu AMDGPU LLVM backend. Izvi zviri pachena kuti icodename yeNavi GPUs, sezvo ikozvino Vega GPUs yakasarudzwa "GFX900". Uye kushandiswa kweGCN dhizaini kunoratidzwa neinotevera mitsara yekodhi:
- EF_AMDGPU_MACH_AMDGCN_LAST =
- EF_AMDGPU_MACH_AMDGCN_GFX1010
Sezvakataurwa naPhoronix, rutsigiro rwakazara rweNavi haruitike mune inotevera Linux 5.2 kernel, uye ingangove yakanonoka kusvika pakuburitswa kweLinux 5.3 kernel. Parizvino, kuburitswa kweiyo yakagadzikana Linux kernel 5.3 kwakarongwa munaGunyana chete. Kusvika panguva iyoyo, vashandisi veLinux vangangofanira kushandisa mamwe ma hacks uye matekiniki kuti maNavi GPU matsva ashande nemazvo. Kana, chokwadi, makadhi evhidhiyo eNavi-based akanyatsobuda zhizha rino, sezvaimbotarisirwa.
Sezvineiwo, kwakasiyana masosi akamboratidza kuti Navi ichave nyowani nyowani yedhizaini yekuvaka, uye kwete imwe vhezheni yeGCN. Izvi zvinogona kureva kuti maGPU matsva anogona kupfuura 4096 stream processors per die muganho wakavakirwa muGCN. Zvisinei, sezvaunogona kuona, izvi hazvisizvo. Ngatiyeukei kuti yekutanga vhezheni yeGCN architecture yakagadziridzwa kumashure mumazuva e28-nm AMD graphics processors muRadeon makadhi evhidhiyo 7000. Naizvozvo, haina kunyatsokodzera 7-nm chips, uye kwete chete nekuda kweiyo kuganhurirwa pahuwandu hwema processor stream.
