I whakaatu a Timur Kristóf, he kaimahi kirimana a Valve, i ngā mahere hei whakapai ake i te tautoko Linux mō ngā kāri whakairoiro AMD GCN 1.0 "Southern Island" me 1.1 "Sea Islands". I te tau kua hipa, i rite te taraiwa AMDGPU ki te taraiwa Radeon mō ngā kāri whakairoiro GCN 1.x, ā, i whakahohea mā te taunoa i roto i te pūtake waehere kernel Linux 6.19, i whakaritea kia tukuna i te marama o Pēpuere. I tukuna ngā kāri GCN 1.x mai i te tau 2012 ki te 2019, ā, e kapi ana i ngā tauira pēnei i a Radeon HD 77xx/78xx/79xx/87xx/88xx/89xx, Radeon R9 280, FirePro W4000-W9000, Radeon Sky 700/900, Radeon R9 265/270/370, Radeon R9 290/390, HD 7790/8870 me ētahi atu kāri ataata o ngā whānau Radeon Rx 200/Rx 300.
Kei roto i ngā mahere te whakawhanaketanga atu o te tautoko GCN 1.x i roto i te Linux, ā, ka whai hua ētahi o ēnei mō ētahi atu GPU, pērā i te whānau Polaris.
- Te whakatinanatanga o te tautoko mō ngā whakarerekētanga hōputu (whakarerekētanga hōputu DRM) mō ngā GPU o te raupapa SI, CIK, VI me Polaris, e āhei ai te whakamahi i ngā kaiwhakahaere whakahiato e hangai ana ki Vulkan, te taraiwa Zink OpenGL me ētahi atu wāhanga.
- Te tāpiri i te tautoko mō ngā pūmana piriti whakaatu TRAVIS me NUTMEG, ka taea ai te whakamahi i te AMDGPU mā te taunoa i roto i ngā whirihoranga me ngā APU whānau CIK.
- Te whakahou i te whakahaere hiko. Ka whakamahia e ngā GPU tawhito te waehere whakahaere hiko motuhake, "DPM," he rerekē tēnei i te waehere AMDGPU matua. Mā te whakakotahi i te waehere mō ngā GPU tawhito me ētahi atu GPU ka whakakorea te peka motuhake mō ēnei GPU, ka whakaiti i te rahi o te waehere, ka whakangawari ake hoki i te tiaki taraiwa.
- I runga i ngā whakapainga ki te tautoko GCN 1.x i roto i te waehere DC (Display Core), pērā i te kaha ki te whakamahi i ngā putanga ataata anaro, he mea tika kia tangohia te waehere tawhito mō ēnei GPU kāore e whakamahi ana i te DC, ka māmā ake te tiaki taraiwa me te whakaiti i te rahi o te waehere.
- Ka whakatikahia ngā hapa e toe ana pēnei i te whakawhāititanga mana hē i runga i ngā GPU Radeon 430, ngā mata mangu i runga i ngā hononga anarau Radeon HD 7790, me ngā hapa whārangi i runga i ngā GPU SI/CIK.
- Tautoko mō ngā kakano noho-wāhanga (PRT). Kua whakaritea kētia he papaki mō te kernel Linux me te tono kume mō MESA hei whakahohe i tēnei āhuatanga.
- Whakawhitihia te tautoko rarangi i roto i te taraiwa RADV mō ngā GPU tawhito.
