Ravi Sharma nga ekipi i Ubuntu Foundations Team b\u00ebri nj\u00eb p\u00ebrmbledhje t\u00eb pun\u00ebs s\u00eb b\u00ebr\u00eb gjat\u00eb vitit t\u00eb fundit p\u00ebr t\u00eb siguruar mb\u00ebshtetje t\u00eb plot\u00eb p\u00ebr arkitektur\u00ebn ARM64 n\u00eb Ubuntu. Ai thekson se fal\u00eb p\u00ebrmir\u00ebsimit t\u00eb mjeteve dhe infrastruktur\u00ebs, si dhe avancimit t\u00eb ndryshimeve n\u00eb b\u00ebrtham\u00ebn kryesore t\u00eb Linux, gjat\u00eb vitit \u00ebsht\u00eb arritur t\u00eb zgjidhen problemet specifike p\u00ebr ARM64, si shp\u00ebrndarja e paketave p\u00ebrmes nj\u00eb depoje t\u00eb ve\u00e7ant\u00eb, mungesa e mb\u00ebshtetjes p\u00ebr patch-et live p\u00ebr b\u00ebrtham\u00ebn, mund\u00ebsit\u00eb e kufizuara p\u00ebr entuziast\u00ebt e loj\u00ebrave kompjuterike dhe mungesa e Secure Boot n\u00eb laptop\u00ebt me \u00e7ipa Qualcomm Snapdragon. <\/p>\n

Paketat p\u00ebr arkitektur\u00ebn ARM64 jan\u00eb transportuar nga portet (ports.ubuntu.com) n\u00eb arkivin kryesor t\u00eb Ubuntu (archive.ubuntu.com), duke mund\u00ebsuar p\u00ebrdorimin e t\u00eb nj\u00ebjt\u00ebs infrastruktur\u00eb q\u00eb p\u00ebrdoret p\u00ebr arkitektur\u00ebn x86_64 p\u00ebr shp\u00ebrndarjen e tyre. Paketat p\u00ebr ARM64 tani shp\u00ebrndahen p\u00ebrmes sistemit fillestar t\u00eb pasqyrave, gj\u00eb q\u00eb ka rritur shpejt\u00ebsin\u00eb dhe besueshm\u00ebrin\u00eb gjat\u00eb shkarkimit. Migrimi k\u00ebrkoi ndryshime n\u00eb paketat cloud-init, live-build, livecd-rootfs dhe ubuntu-release-upgrader. Ndryshimet jan\u00eb p\u00ebrfshir\u00eb n\u00eb versionin 26.04 t\u00eb Ubuntu dhe jan\u00eb n\u00eb proces e b\u00ebn portimin p\u00ebr Ubuntu 24.04 LTS.\n
Sh\u00ebrbimi Livepatch, i cili lejon aplikimin e rregullimeve n\u00eb b\u00ebrtham\u00ebn Linux n\u00eb nj\u00eb sistem n\u00eb pun\u00eb pa e rinisur at\u00eb, \u00ebsht\u00eb shp\u00ebrndar\u00eb n\u00eb sistemet e bazuara n\u00eb arkitektur\u00ebn ARM64. M\u00eb par\u00eb, patch-et live shp\u00ebrndaheshin vet\u00ebm p\u00ebr arkitektur\u00ebn x86_64, pasi n\u00eb b\u00ebrthin\u00ebn e Linux p\u00ebr arkitektur\u00ebn ARM64 mungonte mb\u00ebshtetja p\u00ebr ndjekjen e besueshme t\u00eb grumbullit (CONFIG_HAVE_RELIABLE_STACKTRACE) p\u00ebr identifikimin e aktivitetit t\u00eb lidhur me trajtimin e nd\u00ebrprerjeve, dhe n\u00eb mjetet objtool dhe kpatch mungonin mund\u00ebsit\u00eb e plota p\u00ebr vler\u00ebsimin e gjendjes para dhe pas aplikimit t\u00eb patchit.

\u00cbsht\u00eb formuar nj\u00eb paket\u00eb e stabilizuar snap me klientin Steam, e nd\u00ebrtuar p\u00ebr arkitektur\u00ebn ARM64. Pasi klienti Steam p\u00ebr Linux \u00ebsht\u00eb i disponuesh\u00ebm vet\u00ebm p\u00ebr arkitektur\u00ebn x86, p\u00ebr ta ekzekutuar at\u00eb n\u00eb sistemet ARM64 \u00ebsht\u00eb p\u00ebrdorur nj\u00eb shtres\u00eb emulimi e bazuar n\u00eb paket\u00ebn FEX. Gjat\u00eb emulimit, mb\u00ebshtetet kalimi i GPU dhe p\u00ebrdorimi i Wine, Proton, DXVK dhe vkd3d p\u00ebr t\u00eb ekzekutuar loj\u00ebrat kompjuterike t\u00eb nd\u00ebrtuara p\u00ebr arkitektur\u00ebn x86_64 dhe t\u00eb shp\u00ebrndara p\u00ebrmes katalogut Steam. Puna e paket\u00ebs snap \u00ebsht\u00eb testuar n\u00eb laptop\u00ebt me \u00e7ipa Qualcomm Snapdragon X Elite, NVIDIA DGX Spark dhe Radxa Orion O6.\n
\u00cbsht\u00eb shtuar mb\u00ebshtetja p\u00ebr laptop\u00ebt me \u00e7ipa Qualcomm Snapdragon X Elite, si Lenovo Thinkpad X13s\/T14s dhe Dell XPS 9345. Fillimisht, mb\u00ebshtetja p\u00ebr k\u00ebto pajisje u shtua n\u00eb imazhin ISO baz\u00eb p\u00ebr sistemet ARM64, por nuk ishte e mundur ta p\u00ebrdorim at\u00eb p\u00ebr t\u00eb b\u00ebr\u00eb boot n\u00eb modalitetin Secure Boot p\u00ebr shkak t\u00eb p\u00ebrdorimit t\u00eb konfigurimeve t\u00eb ve\u00e7anta t\u00eb Device Tree, t\u00eb cilat firmware-i i laptop\u00ebve nuk i kalonte n\u00eb kernelin Linux. Konfigurimet e nevojshme t\u00eb Device Tree u ngarkuan nga ngarkuesi GRUB nga nj\u00eb skedar i ve\u00e7ant\u00eb, i cili nuk mbulohej nga n\u00ebnshkrimi digjital.\n
P\u00ebr zgjidhjen e problemit, b\u00ebrthama dhe baza e t\u00eb dh\u00ebnave t\u00eb Device Tree u bashkuan n\u00eb nj\u00eb skedar monolitik EFI, t\u00eb ngjash\u00ebm me UKI (Unified Kernel Image), i n\u00ebnshkruar me firm\u00ebn digjitale t\u00eb shp\u00ebrndarjes. P\u00ebr t\u00eb ngarkuar k\u00ebt\u00eb skedar, u krijua nj\u00eb nd\u00ebrmjet\u00ebs EFI e re \"stubble\", e cila gjat\u00eb ngarkimit p\u00ebrcakton modelin e pajisjes p\u00ebrmes SMBIOS, duke zgjedhur t\u00eb dh\u00ebnat e nevojshme t\u00eb Device Tree dhe duke i futur ato n\u00eb b\u00ebrtham\u00eb, pa shp\u00ebrblyer zinxhirin e besimit t\u00eb Secure Boot. Po punohet p\u00ebr zbatimin e mb\u00ebshtetjes p\u00ebr laptop\u00ebt me \u00e7ipa Snapdragon X2 Elite. <\/p>\n
\u00cbsht\u00eb p\u00ebrgatitur nj\u00eb prototip i imazhit t\u00eb ngarkimit bazuar n\u00eb Ubuntu 26.04 p\u00ebr laptop\u00ebt me ARM64 SoC CIX P1, i cili, n\u00eb dallim nga Snapdragon, \u00ebsht\u00eb n\u00eb gjendje t\u00eb p\u00ebrcaktoj\u00eb konfigurimin p\u00ebrmes tabelave ACPI pa p\u00ebrdorur Device Tree.\n
Kompania Google njoftoi publikimin e versioneve zyrtare t\u00eb Chrome p\u00ebr sistemet Linux t\u00eb bazuara n\u00eb arkitektur\u00ebn ARM64, gj\u00eb q\u00eb do t\u00eb mund\u00ebsoj\u00eb ekzekutimin e shfletuesit Chrome n\u00eb versionet ARM64 t\u00eb Ubuntu, i cili p\u00ebrmban modulin CDM (Content Decryption Module) Widevine, i cili nuk \u00ebsht\u00eb i disponuesh\u00ebm n\u00eb Chromium.

P\u00ebr m\u00eb tep\u00ebr, mb\u00ebshtetje p\u00ebr Widevine planifikohet t\u00eb integrohet n\u00eb pakot snap me Firefox dhe Spotify.\n
Jan\u00eb shtuar versione t\u00eb reja aplikacionesh, t\u00eb disponueshme n\u00eb formatin snap p\u00ebr arkitektur\u00ebn ARM64. Nd\u00ebr t\u00eb tjera, p\u00ebr ARM64 ka filluar publikimi i pakove snap me OnlyOffice, FreeCAD dhe Teams for Linux. <\/ul>\n
