Pachetele pentru ARM64 sunt acum livrate prin sistemul principal de oglinzi, ceea ce a crescut viteza \u0219i fiabilitatea la desc\u0103rcare. Migrarea a necesitat modific\u0103ri \u00een pachetele cloud-init, live-build, livecd-rootfs \u0219i ubuntu-release-upgrader. Modific\u0103rile au fost incluse \u00een Ubuntu 26.04 \u0219i sunt \u00een proces de backport pentru Ubuntu 24.04 LTS.\n<li class=\"l\"> Serviciul Livepatch, care permite aplicarea de remedii \u00een kernelul Linux pe un sistem \u00een func\u021biune f\u0103r\u0103 a necesita repornirea acestuia, a fost extins pentru sistemele bazate pe arhitectura ARM64. Anterior, live patch-urile erau disponibile doar pentru arhitectura x86_64, deoarece kernelul Linux pentru arhitectura ARM64 nu avea suport pentru backtrace-uri fiabile (CONFIG_HAVE_RELIABLE_STACKTRACE) pentru a identifica activitatea legat\u0103 de gestionarea \u00eentreruperilor, iar \u00een instrumentele objtool \u0219i kpatch lipseau capacit\u0103\u021bile complete pentru evaluarea st\u0103rii \u00eenainte \u0219i dup\u0103 aplicarea patch-ului. Suportul pentru live patch-uri pentru ARM64 este disponibil \u00een Ubuntu 26.04 LTS \u0219i Ubuntu Core 26.\n<li class=\"l\"> A fost creat un pachet snap stabil cu clientul Steam, compilat pentru arhitectura ARM64. Deoarece clientul Steam pentru Linux este disponibil doar pentru arhitectura x86, pentru a-l rula pe sistemele ARM64 este utilizat un strat de emulare bazat pe pachetul FEX. La emulare, este sus\u021binut prin GPU \u0219i utilizarea Wine, Proton, DXVK \u0219i vkd3d pentru a rula jocurile de calculator compilate pentru arhitectura x86_64 \u0219i distribuite prin catalogul Steam. Func\u021bionarea pachetului snap a fost testat\u0103 pe laptopuri cu cipuri Qualcomm Snapdragon X Elite, NVIDIA DGX Spark \u0219i Radxa Orion O6.\n<li class=\"l\"> A fost ad\u0103ugat suport pentru laptopuri bazate pe cipuri Qualcomm Snapdragon X Elite, cum ar fi Lenovo Thinkpad X13s \/ T14s \u0219i Dell XPS 9345. Ini\u021bial, suportul pentru aceste dispozitive a fost ad\u0103ugat \u00een imaginea ISO de baz\u0103 pentru sistemele ARM64, dar nu a putut fi utilizat pentru \u00eenc\u0103rcare \u00een mod Secure Boot din cauza utiliz\u0103rii unor configura\u021bii separate ale Device Tree, care nu erau transmise nucleului Linux de firmware-ul laptopurilor. Set\u0103rile necesare pentru Device Tree erau \u00eenc\u0103rcate de bootloaderul GRUB dintr-un fi\u0219ier separat, care nu era acoperit de semn\u0103tura digital\u0103.\n<p>Pentru a rezolva problema, nucleul \u0219i baza de date Device Tree au fost unite \u00eentr-un singur fi\u0219ier EFI monolitic, similar cu UKI (Unified Kernel Image), semnat cu semn\u0103tura digital\u0103 a distribu\u021biei. A fost creat\u0103 o nou\u0103 interfa\u021b\u0103 EFI denumit\u0103 \u201estubble\u201d, care, la \u00eenc\u0103rcare, identific\u0103 modelul dispozitivului prin SMBIOS, aleg\u00e2nd datele necesare din Device Tree \u0219i introduc\u00e2ndu-le \u00een nucleu, f\u0103r\u0103 a afecta lan\u021bul de \u00eencredere Secure Boot. Se lucreaz\u0103 la implementarea suportului pentru laptopuri pe cipurile Snapdragon X2 Elite.      <\/p>\n<li class=\"l\"> A fost preg\u0103tit un prototip de imagine de boot bazat pe Ubuntu 26.04 pentru laptopuri cu ARM64 SoC CIX P1, care, spre deosebire de Snapdragon, permite determinarea configura\u021biei prin intermediul tabelelor ACPI f\u0103r\u0103 a utiliza Device Tree.\n<li class=\"l\"> Compania Google a anun\u021bat publicarea oficial\u0103 a versiunilor Chrome pentru sistemele Linux bazate pe arhitectura ARM64, ceea ce va permite rularea \u00een versiunile ARM64 ale Ubuntu a browserului Chrome, care con\u021bine modulul CDM (Content Decryption Module) Widevine, care nu este disponibil \u00een Chromium. Livrarea Widevine va permite vizionarea con\u021binutului media protejat prin drepturi de autor (DRM), g\u0103zduit pe servicii precum Netflix, Spotify \u0219i Disney+, f\u0103r\u0103 a necesita patch-uri externe. De asemenea, se inten\u021bioneaz\u0103 integrarea suportului Widevine \u00een pachetele snap cu Firefox \u0219i Spotify.\n<li class=\"l\"> Au fost ad\u0103ugate noi versiuni de aplica\u021bii disponibile \u00een format snap pentru arhitectura ARM64. Printre altele, pentru ARM64 a \u00eenceput publicarea pachetelor snap cu OnlyOffice, FreeCAD \u0219i Teams for Linux.    <\/ul>\n<p>Sursa: <a content=\"nofollow\" rel=\"nofollow\"
