Istaknuto je da su, zahvaljuju\u0107i pobolj\u0161anjima alata i infrastrukture, kao i promovisanju promena u osnovnom jezgru Linux-a, tokom godine re\u0161eni specifi\u010dni problemi vezani za ARM64, kao \u0161to su distribucija paketa putem zasebnog repozitorijuma, nedostatak podr\u0161ke za live-patch-e za jezgro, ograni\u010dene mogu\u0107nosti za ljubitelje video igara i nedostupnost Secure Boot-a na laptopima sa Qualcomm Snapdragon \u010dipovima.      <\/p>\n<p>Glavna postignu\u0107a:  <\/p>\n<ul>\n<li class=\"l\"> Paketi za ARM64 arhitekturu preba\u010deni su iz portova (ports.ubuntu.com) u glavni arhiv Ubuntu (archive.ubuntu.com), \u0161to je omogu\u0107ilo kori\u0161\u0107enje iste infrastrukture koja se koristi za x86_64 arhitekturu. Paketi za ARM64 sada se distribuiraju putem primarnog sistema ogledala, \u0161to je pobolj\u0161alo brzinu i pouzdanost prilikom preuzimanja. Migracija je zahtevala izmene u paketima cloud-init, live-build, livecd-rootfs i ubuntu-release-upgrader. Izmene su uklju\u010dene u Ubuntu 26.04 i trenutno se rade na b\u0430ckport-ovanju za Ubuntu 24.04 LTS.\n<li class=\"l\"> Livepatch servis, koji omogu\u0107ava primenu ispravki u Linux jezgru na aktivnom sistemu bez ponovnog pokretanja, pro\u0161iren je na sisteme zasnovane na ARM64 arhitekturi. Ranije su live-patch-e bile dostupne samo za x86_64 arhitekturu, jer u Linux jezgru za ARM64 nije bila dostupna podr\u0161ka za pouzdane pra\u0107enje stoga (CONFIG_HAVE_RELIABLE_STACKTRACE) za identifikaciju aktivnosti vezanih za obradu prekida, a u alatima objtool i kpatch nije bilo punih mogu\u0107nosti za procenu stanja pre i posle primene patch-a. Podr\u0161ka za live-patch-e za ARM64 osigurana je za Ubuntu 26.04 LTS i Ubuntu Core 26.\n<li class=\"l\"> Formiran je stabilan snap paket sa Steam klijentom, sklopljen za ARM64 arhitekturu. Kako je Steam klijent za Linux dostupan samo za x86 arhitekturu, za njegovo pokretanje na ARM64 sistemima koristi se sloj emulacije zasnovan na FEX paketu. Tokom emulacije podr\u017eava se prolaz GPU-a i kori\u0161\u0107enje Wine-a, Proton-a, DXVK-a i vkd3d-a za igranje video igara sklopljenih za x86_64 arhitekturu i distribuiranih putem Steam kataloga. Rad snap paketa testiran je na laptopima sa \u010dipovima Qualcomm Snapdragon X Elite, NVIDIA DGX Spark i Radxa Orion O6.\n<li class=\"l\"> Dodana je podr\u0161ka za laptope bazirane na Qualcomm Snapdragon X Elite \u010dipovima, kao \u0161to su Lenovo Thinkpad X13s\/T14s i Dell XPS 9345. Prvobitno je podr\u0161ka ovih ure\u0111aja dodana u osnovnu ISO sliku za ARM64 sisteme, ali nije se mogla koristiti za pokretanje u Secure Boot re\u017eimu zbog upotrebe odvojenih konfiguracija Device Tree, koje firmware laptopa nije prenosio Linux jezgru. Potrebne Device Tree postavke u\u010ditane su od strane GRUB bootloader-a iz odvojene datoteke koja nije bila obuhva\u0107ena digitalnim potpisom.\n<p>Za re\u0161evanje te\u017eave sta bila jedro in baza podatkov Device Tree zdru\u017eena v eni monolitni EFI-datoteki, podobni UKI (Unified Kernel Image), ki je digitalno podpisana z dodeljenim podpisom. Za nalaganje te datoteke je bila ustvarjena nova EFI-sloj &#171;stubble&#187;, ki ob nalaganju dolo\u010da model naprave preko SMBIOS, izbira potrebne podatke Device Tree in jih priklju\u010di v jedro, ne da bi prekinila verigo zaupanja Secure Boot. Poteka delo na implementaciji podpore za prenosnike na \u010dipih Snapdragon X2 Elite.      <\/p>\n<li class=\"l\"> Pripremljen je prototype boot slike na bazi Ubuntu 26.04 za laptope sa ARM64 SoC CIX P1, koji, za razliku od Snapdragon-a, omogu\u0107ava odre\u0111ivanje konfiguracije putem ACPI tabela bez upotrebe Device Tree.\n<li class=\"l\"> Kompanija Google je najavila objavljivanje zvani\u010dnih Chrome izdanja za Linux sisteme bazirane na ARM64 arhitekturi, \u0161to \u0107e omogu\u0107iti pokretanje Chrome pretra\u017eiva\u010da u ARM64 izdanjima Ubuntu-a, koji sadr\u017ei CDM modul (Content Decryption Module) Widevine, koji nije dostupan u Chromium-u. Dostupnost Widevine-a \u0107e omogu\u0107iti pregledavanje medijskog sadr\u017eaja za\u0161ti\u0107enog autorskim pravima (DRM) bez potrebe za sporednim zakrpama, na servisima kao \u0161to su Netflix, Spotify i Disney+. Osim toga, planira se integracija podr\u0161ke za Widevine u snap pakete sa Firefox-om i Spotify-jem.\n<li class=\"l\"> Dodate su nove verzije aplikacija dostupne u snap formatu za ARM64 arhitekturu. Osim toga, zapo\u010dela je objava snap paketa za ARM64 sa OnlyOffice, FreeCAD i Teams za Linux.    <\/ul>\n<p>Izvor: <a content=\"nofollow\" rel=\"nofollow\"
