UTimur Kristóf, umthengisi ongaphantsi kweValve, uveze izicwangciso zokuphucula inkxaso yeLinux kwiikhadi zemizobo ze-AMD GCN 1.0 "Southern Island" kunye ne-1.1 "Sea Islands". Kunyaka ophelileyo, umqhubi we-AMDGPU waziswa ngokulinganayo nomqhubi weRadeon kwiikhadi zemizobo ze-GCN 1.x kwaye wavulwa ngokuzenzekelayo kwikhowudi ye-Linux 6.19 kernel, ecwangciselwe ukukhutshwa ngoFebruwari. Iikhadi ze-GCN 1.x zakhutshwa ukususela ngo-2012 ukuya ku-2019 kwaye zigubungela iimodeli ezifana neRadeon HD 77xx/78xx/79xx/87xx/88xx/89xx, iRadeon R9 280, iFirePro W4000-W9000, iRadeon Sky 700/900, iRadeon R9 265/270/370, iRadeon R9 290/390, iHD 7790/8870 kunye nezinye iikhadi zevidiyo zeentsapho zeRadeon Rx 200/Rx 300.
Izicwangciso ziquka uphuhliso olongezelelekileyo lwenkxaso ye-GCN 1.x kwiLinux, ezinye zazo eziya kuba luncedo nakwezinye ii-GPU, ezifana nosapho lwePolaris.
- Ukusetyenziswa kwenkxaso yee-format modifiers (DRM format modifier) kwii-GPU ze-SI, CIK, VI kunye ne-Polaris series, eziya kuvumela ukusetyenziswa kwabaphathi be-compositing abasekelwe kwi-Vulkan, umqhubi we-Zink OpenGL kunye nezinye izinto.
- Ukongeza inkxaso kwi-TRAVIS kunye ne-NUTMEG display bridge controllers, eya kuvumela ukusetyenziswa kwe-AMDGPU ngokuzenzekelayo kwii-configurations kunye ne-CIK family APUs.
- Ukulungiswa kolawulo lwamandla. IiGPU ezindala zisebenzisa ikhowudi yolawulo lwamandla eyahlukileyo, "iDPM," eyahlukileyo kwikhowudi ephambili ye-AMDGPU. Ukudibanisa ikhowudi yeeGPU ezindala nezinye iiGPU kuya kususa isebe elahlukileyo lala maGPU, kunciphise ubungakanani bekhowudi, kwaye kube lula ukugcinwa komqhubi.
- Ngenxa yokuphuculwa kwenkxaso ye-GCN 1.x kwikhowudi ye-DC (Display Core), njengokukwazi ukusebenzisa iziphumo zevidiyo ze-analog, kuyavakala ukususa ikhowudi endala kwezi GPU zingasebenzisi i-DC, nto leyo eya kwenza kube lula ukugcinwa komqhubi kwaye inciphise ubungakanani bekhowudi.
- Ilungisa iimpazamo eziseleyo ezifana nokunciphisa amandla ngendlela engafanelekanga kwiRadeon 430 GPUs, izikrini ezimnyama kwiRadeon HD 7790 analog connectors, kunye neempazamo zephepha kwi-SI/CIK GPUs.
- Inkxaso yee-partial resident textures (PRT). I-patch ye-Linux kernel kunye nesicelo sokutsala se-MESA sele zilungisiwe ukuze zisebenze olu phawu.
- Inkxaso yomgca wokudlulisa kwi-RADV driver yee-GPU ezindala.
