W repozytorium, w kt\u00f3rym powstaje wydanie j\u0105dra Linux 5.19, przyj\u0119to kolejny zestaw zmian zwi\u0105zanych z podsystemem DRM (Direct Rendering Manager) i sterownikami graficznymi. Przyj\u0119ty zestaw poprawek jest interesuj\u0105cy, poniewa\u017c zawiera 495 tysi\u0119cy linii kodu, co odpowiada ca\u0142kowitemu rozmiarowi zmian w ka\u017cdej ga\u0142\u0119zi j\u0105dra (na przyk\u0142ad, w j\u0105drze 5.17 dodano 506 tysi\u0119cy linii kodu). <\/p>\n

Oko 400 tysi\u0119cy dodatkowych linii pochodzi z automatycznie generowanych plik\u00f3w nag\u0142\u00f3wkowych z danymi dla rejestr\u00f3w ASIC w sterowniku dla GPU AMD. Kolejne 22,5 tysi\u0105ca linii zapewnia wst\u0119pn\u0105 realizacj\u0119 wsparcia dla AMD SoC21. Ca\u0142kowity rozmiar sterownika dla GPU AMD przekroczy\u0142 4 miliony linii kodu (dla por\u00f3wnania, ca\u0142e j\u0105dro Linux 1.0 zawiera\u0142o 176 tysi\u0119cy linii kodu, 2.0 \u2014 778 tysi\u0119cy, 2.4 \u2014 3,4 miliona, 5.13 \u2014 29,2 miliona). Opr\u00f3cz SoC21 w sterowniku AMD wprowadzono wsparcie dla SMU 13.x (System Management Unit), zaktualizowano wsparcie dla USB-C i GPUVM oraz przygotowano do wsparcia dla nast\u0119pnych pokole\u0144 platform RDNA3 (RX 7000) i CDNA (AMD Instinct). <\/p>\n

W sterowniku Intel najwi\u0119ksza ilo\u015b\u0107 zmian (5,6 tysi\u0105ca) wyst\u0119puje w kodzie odpowiedzialnym za zarz\u0105dzanie energi\u0105. Do sterownika Intel dodano tak\u017ce identyfikatory GPU Intel DG2 (Arc Alchemist), kt\u00f3re s\u0105 u\u017cywane w laptopach, zapewniono wst\u0119pn\u0105 obs\u0142ug\u0119 platformy Intel Raptor Lake-P (RPL-P), dodano informacje o kartach graficznych Arctic Sound-M, zrealizowano ABI dla silnik\u00f3w obliczeniowych, dla kart DG2 dodano wsparcie dla formatu Tile4, a dla system\u00f3w opartych na mikroarchitekturze Haswell wprowadzono wsparcie dla DisplayPort HDR. <\/p>\n

W sterowniku Nouveau zmiany dotkn\u0119\u0142y \u0142\u0105cznie oko\u0142o stu linii kodu (przeszed\u0142 na u\u017cycie obs\u0142ugi drm_gem_plane_helper_prepare_fb, dla niekt\u00f3rych struktur i zmiennych zastosowano statyczne przydzielanie pami\u0119ci). Je\u015bli chodzi o wykorzystanie w Nouveau otwartych przez firm\u0119 NVIDIA \u017ar\u00f3de\u0142 modu\u0142\u00f3w j\u0105dra, prace na razie ograniczaj\u0105 si\u0119 do identyfikacji i usuwania b\u0142\u0119d\u00f3w. W przysz\u0142o\u015bci planuje si\u0119 wykorzystanie opublikowanego oprogramowania w celu zwi\u0119kszenia wydajno\u015bci sterownika.
