AMD twb tau pib ua haujlwm ntawm cov tsav tsheb rau nws yav tom ntej Navi-based video phaib rau Linux-based operating systems. Cov peev txheej paub zoo Phoronix tau tshawb pom cov ntaub ntawv hauv kab tshiab ntawm AMD tus tsav tsheb code uas Navi GPUs tseem yuav siv cov qub GCN architecture zoo.
Lub codename "GFX1010" tau pom nyob rau hauv AMDGPU LLVM backend. Qhov no yog kom meej meej codename rau Navi GPUs, raws li tam sim no Vega GPUs raug xaiv "GFX900". Thiab kev siv GCN architecture yog qhia los ntawm cov kab hauv qab no:
- EF_AMDGPU_MACH_AMDGCN_LAST =
- EF_AMDGPU_MACH_AMDGCN_GFX1010
Raws li tau sau tseg los ntawm Phoronix, kev txhawb nqa Navi tag nrho tsis zoo li yuav raug siv rau hauv Linux 5.2 kernel tom ntej, thiab feem ntau yuav ncua mus txog thaum tso tawm ntawm Linux 5.3 kernel. Tam sim no, kev tso tawm ntawm Linux ntsiav 5.3 ruaj khov yog npaj rau lub Cuaj Hli nkaus xwb. Txog thaum ntawd, cov neeg siv Linux yuav tau siv qee qhov hacks thiab tricks kom tau txais Navi GPUs tshiab los ua haujlwm zoo. Yog tias, tau kawg, Navi-raws li daim npav video tiag tiag tawm lub caij ntuj sov no, raws li yav dhau los xav tau.
Interestingly, ntau qhov chaw tau qhia yav dhau los tias Navi yuav yog cov duab kos duab tshiab, thiab tsis yog lwm qhov version ntawm GCN. Qhov no tuaj yeem txhais tau tias GPUs tshiab tuaj yeem hla dhau 4096 kwj processors ib qho kev txwv tuag uas tau tsim rau hauv GCN. Txawm li cas los xij, raws li koj tuaj yeem pom, qhov no tsis yog li ntawd. Cia peb nco ntsoov tias thawj tus qauv ntawm GCN architecture tau tsim rov qab rau hauv cov hnub ntawm 28-nm AMD graphics processors hauv Radeon 7000 video phaib. Yog li ntawd, nws tsis zoo heev rau 7-nm chips, thiab tsis yog vim li ntawd xwb. txwv ntawm tus naj npawb ntawm cov kwj processors.
