Ravi Sharma nga ekipi Ubuntu Foundations p\u00ebrfundoi p\u00ebrmbledhjen e pun\u00ebs s\u00eb b\u00ebr\u00eb gjat\u00eb vitit t\u00eb kaluar 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 promovimit t\u00eb ndryshimeve n\u00eb b\u00ebrtham\u00ebn kryesore t\u00eb Linux, \u00ebsht\u00eb arritur t\u00eb zgjidhen probleme specifike p\u00ebr ARM64, si shp\u00ebrndarja e pakove p\u00ebrmes nj\u00eb depoje t\u00eb ve\u00e7ant\u00eb, mungesa e mb\u00ebshtetjes p\u00ebr patch-live p\u00ebr b\u00ebrtham\u00ebn, mund\u00ebsi t\u00eb kufizuara p\u00ebr entuziast\u00ebt e loj\u00ebrave p\u00ebr kompjuter\u00eb dhe paqart\u00ebsit\u00eb me Secure Boot n\u00eb laptop\u00ebt me \u00e7ipa Qualcomm Snapdragon. <\/p>\n

Pakot p\u00ebr arkitektur\u00ebn ARM64 jan\u00eb transferuar nga portet (ports.ubuntu.com) n\u00eb arkivin kryesor t\u00eb Ubuntu (archive.ubuntu.com), duke lejuar p\u00ebrdorimin e t\u00eb nj\u00ebjt\u00ebs infrastruktur\u00eb q\u00eb p\u00ebrdoret p\u00ebr arkitektur\u00ebn x86_64. Pakot p\u00ebr ARM64 tani dostohen p\u00ebrmes sistemit primar t\u00eb pasqyrave, \u00e7ka ka rritur shpejt\u00ebsin\u00eb dhe besueshm\u00ebrin\u00eb gjat\u00eb shkarkimit t\u00eb tyre. Migrimi k\u00ebrkoi ndryshime n\u00eb pakot cloud-init, live-build, livecd-rootfs dhe ubuntu-release-upgrader. Ndryshimet u p\u00ebrfshin\u00eb n\u00eb versionin Ubuntu 26.04 dhe jan\u00eb n\u00eb procesin e rikthimit p\u00ebr Ubuntu 24.04 LTS.\n
Sh\u00ebrbimi Livepatch, i cili lejon t\u00eb b\u00ebhen p\u00ebrmir\u00ebsime n\u00eb b\u00ebrtham\u00ebn Linux n\u00eb nj\u00eb sistem funksional pa rinisje, \u00ebsht\u00eb shp\u00ebrndar\u00eb p\u00ebr sistemet e bazuara n\u00eb arkitektur\u00ebn ARM64. M\u00eb par\u00eb, Live-patch kishte shp\u00ebrndar\u00eb vet\u00ebm p\u00ebr arkitektur\u00ebn x86_64, pasi b\u00ebrthama Linux p\u00ebr arkitektur\u00ebn ARM64 nuk kishte mb\u00ebshtetje p\u00ebr gjurmimet e besueshme t\u00eb stack-ut (CONFIG_HAVE_RELIABLE_STACKTRACE) p\u00ebr t\u00eb identifikuar aktivitetin q\u00eb lidhet me trajtimin e nd\u00ebrprerjeve, dhe n\u00eb mjetet objtool dhe kpatch mungonin mund\u00ebsit\u00eb e plota p\u00ebr t\u00eb vler\u00ebsuar gjendjen para dhe pas aplikimit t\u00eb patch-it. Mb\u00ebshtetje p\u00ebr Live-patch p\u00ebr ARM64 \u00ebsht\u00eb ofruar p\u00ebr Ubuntu 26.04 LTS dhe Ubuntu Core 26.\n
\u00cbsht\u00eb formuar nj\u00eb paket\u00eb stabionale snap me klientin Steam, e nd\u00ebrtuar p\u00ebr arkitektur\u00ebn ARM64. Duke qen\u00eb se klienti Steam p\u00ebr Linux \u00ebsht\u00eb n\u00eb dispozicion vet\u00ebm p\u00ebr arkitektur\u00ebn x86, p\u00ebr t\u00eb nisur at\u00eb n\u00eb sistemet ARM64 p\u00ebrdoret nj\u00eb shtres\u00eb emulimi n\u00eb baz\u00eb t\u00eb paket\u00ebs FEX. Gjat\u00eb emulimit p\u00ebrkrahet kalimi i GPU-s\u00eb dhe p\u00ebrdorimi i Wine, Proton, DXVK dhe vkd3d p\u00ebr t\u00eb ekzekutuar loj\u00ebra kompjuterike, t\u00eb nd\u00ebrtuara p\u00ebr arkitektur\u00ebn x86_64 dhe shp\u00ebrndara p\u00ebrmes katalogut Steam. Funksionimi i paket\u00ebs snap \u00ebsht\u00eb testuar n\u00eb notebook-e me \u00e7ipa Qualcomm Snapdragon X Elite, NVIDIA DGX Spark dhe Radxa Orion O6.\n
\u00cbsht\u00eb shtuar mb\u00ebshtetje 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 baz\u00eb iso p\u00ebr sistemet ARM64, por nuk mund t\u00eb p\u00ebrdoret p\u00ebr ngarkim 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.
