L'ann\u00e9e derni\u00e8re, le pilote AMDGPU a \u00e9t\u00e9 mis \u00e0 niveau pour \u00e9galer les capacit\u00e9s du pilote Radeon pour les familles de cartes graphiques GCN 1.x et a \u00e9t\u00e9 activ\u00e9 par d\u00e9faut dans la base de code du noyau Linux 6.19, dont la sortie est pr\u00e9vue pour f\u00e9vrier. Les cartes GCN 1.x ont \u00e9t\u00e9 produites de 2012 \u00e0 2019 et incluent des mod\u00e8les tels que 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 et d'autres cartes graphiques des familles Radeon Rx 200 \/ Rx 300.    <\/p>\n<p>Parmi les projets pour le d\u00e9veloppement futur du support de GCN 1.x sous Linux, certains seront \u00e9galement utiles pour d'autres GPU, comme les familles Polaris.    <\/p>\n<ul>\n<li class=\"l\"> Impl\u00e9mentation du support des modificateurs de format (DRM format modifier) pour les GPU des s\u00e9ries SI, CIK, VI et Polaris, permettant l'utilisation de gestionnaires de composition bas\u00e9s sur Vulkan, avec le pilote OpenGL Zink et d'autres composants.\n<li class=\"l\"> Ajout du support des contr\u00f4leurs de pont d'affichage (display bridge) TRAVIS et NUTMEG, permettant d'utiliser AMDGPU par d\u00e9faut dans les configurations avec APU de la famille CIK.\n<li class=\"l\"> Refactorisation de la gestion de l'alimentation. Les anciens GPU utilisent un code de gestion de l'alimentation distinct, \u00ab DPM \u00bb, qui diff\u00e8re du code principal d'AMDGPU. L'unification du code pour les anciens GPU avec les autres permettra de supprimer une branche distincte pour ces GPU, de r\u00e9duire le volume de code et de simplifier la maintenance du pilote.\n<li class=\"l\"> Compte tenu des am\u00e9liorations du support de GCN 1.x dans le code DC (Display Core), telles que la possibilit\u00e9 d'utiliser des sorties vid\u00e9o analogiques, il est judicieux de supprimer l'ancien code pour ces GPU qui n'utilise pas DC, ce qui simplifiera la maintenance du pilote et r\u00e9duira le volume de code.\n<li class=\"l\"> Correction des erreurs persistantes, telles que la limitation incorrecte de la consommation d'\u00e9nergie du GPU Radeon 430, l'\u00e9cran noir sur les connecteurs analogiques de la Radeon HD 7790 et les fautes de page (page faults) sur les GPU des familles SI\/CIK.\n<li class=\"l\"> Support des textures partiellement r\u00e9sidentes (PRT, partially resident texture). Un patch pour le noyau Linux est d\u00e9j\u00e0 pr\u00eat et une demande de modification pour MESA a \u00e9t\u00e9 faite pour activer cette fonctionnalit\u00e9.\n<li class=\"l\"> Support de la file d'attente de transfert (transfer queue) dans le pilote RADV pour les anciens GPU.  <\/ul>\n<p>Source : <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64570\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0422\u0438\u043c\u0443\u0440 \u041a\u0440\u0438\u0441\u0442\u043e\u0444 (Timur Krist&#243;f), \u043e\u0434\u0438\u043d \u0438\u0437 \u0441\u0443\u0431\u043f\u043e\u0434\u0440\u044f\u0434\u0447\u0438\u043a\u043e\u0432 \u0444\u0438\u0440\u043c\u044b Valve, \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u0438\u043b \u043f\u043b\u0430\u043d\u044b \u043f\u043e \u0443\u043b\u0443\u0447\u0448\u0435\u043d\u0438\u044e \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0438 \u0432 Linux \u0432\u0438\u0434\u0435\u043e\u043a\u0430\u0440\u0442 AMD \u0441\u0435\u043c\u0435\u0439\u0441\u0442\u0432\u0430 GCN 1.0 &#171;Southern Island&#187;
