Ngemuva kwezinyanga ezimbili zentuthuko, ILinus Torvalds yethule ukwethulwa kwe- inguqulo entsha ye-kernel ye Linux 5.16 futhi lapho phakathi kwezinguquko eziphawuleka kakhulu kukhona ucingo lwesistimu lwe-futex_waitv lokuthuthukisa ukusebenza kwemidlalo ye-Windows ku-Wine, ukulandelela amaphutha ohlelweni lwefayela nge-fanontify, ikhono lokugcinela inkumbulo amasokhethi enethiwekhi, ukuphathwa okuthuthukisiwe kokulayishwayo nge- umthamo omkhulu wemisebenzi yokubhala, ukusekelwa kwama-multi-drive hard drive, phakathi kwezinye izinto.
Uhlobo olusha ithole ukulungiswa okungu-15415 kubathuthukisi abangu-2105, izinguquko zathinta amafayela angu-12023, yengeze imigqa yekhodi engu-685198, ikhishwe imigqa engu-263867.
Cishe u-44% wazo zonke izinguquko ezethulwe ku-5.16 zihlobene nezishayeli zedivayisi, cishe u-16% wezinguquko zihlobene nokubuyekeza ikhodi eqondene nezakhiwo zehadiwe, u-16% uhlobene nesitaki senethiwekhi, u-4% uhlobene nezinhlelo zamafayela futhi u-4% uhlobene. okuhlobene nesistimu engaphansi ye-kernel yangaphakathi.
Izinto ezintsha ezintsha zeLinux Kernel 5.16
Kule nguqulo entsha indlela yazisa amathuluzi engeziwe okuqapha isimo sesistimu yefayela kanye namaphutha okulandelela. Ukwesekwa kokulandelela iziphazamisi kusetshenzisiwe okwamanje kuphela ye-FS Ext4.
Tambien ukuphathwa kwesiminyaminya sokubhala kwenziwe ngcono Lokhu kwenzeka lapho ivolumu yemisebenzi yokubhala idlula umthamo wedrayivu futhi uhlelo luphoqeleka ukuthi luvimbe izicelo zokubhala zenqubo kuze kube yilapho izicelo esezidlulisiwe seziqediwe.
Enguqulweni entsha, indlela ye-kernel esetshenziswa ukuthola ulwazi mayelana nokuvela kokugcwala okugcwele kanye nokuvinjwa kwemisebenzi yenziwe kabusha ngokuphelele.
I-Btrfs isebenzisa ukusekelwa kobuchwepheshe be-Zoned Namespace, esetshenziswa kuma-hard drive noma ama-NVMe SSD ukuze kuhlukaniswe indawo yokugcina ezindaweni ezakha amaqembu amabhlogo noma imikhakha, lapho kuvunyelwa kuphela ukungezwa okulandelanayo kwedatha, kuyilapho kubuyekezwa lonke iqembu lamabhulokhi.
Indlela yokubhaliswa kohla lwemibhalo isiklanywe kabusha, Lapho inani lokusesha kanye nokukhiya esihlahleni liye lancishiswa ukuze kuthuthukiswe ukusebenza kahle, ngaphezu kokwengeza ukwesekwa okulinganiselwe kokusebenzisa ukucindezela lapho ubhala amakhasi angaphelele, kanye nekhono lokuhlukanisa amakhasi amancane.
Kusistimu yefayela I-Ext4, ukulungiswa kweziphazamisi kuphela okufakiwe kanye nokubalwa okunembe kakhudlwana kwethebula le-inode imingcele yokuvilapha yokuqalisa Ezingeni ledivayisi ye-block, ukulungiselelwa kusetshenziswe okwandisa kakhulu ukusebenza kahle kokusebenza kwezixhumanisi kuma-CPU cores.
Izinketho zokukhweza zengezwe ku-FS F2FS ukulawula ukuhlukana kwamafayela lapho egcinwa (isibonelo, ukulungisa iphutha lokulungiselela ukusebenza ngokulondoloza okuyizicucu).
Ikholi yesistimu entsha yengeziwe, futex_waitv, ukuqapha isimo samafutex amaningi ngesikhathi esisodwa ngocingo olulodwa lwesistimu. Lesi sici sifana nokusebenza kwe-WaitForMultipleObjects etholakala ku-Windows, ukulingisa kwakho nge-futex_waitv kungaba wusizo ekuthuthukiseni ukusebenza kwemidlalo ye-Windows esebenza ku-Wine noma i-Proton.
Isibambi sengeziwe ku-Task Scheduler esicabangela ukuhlanganisa inqolobane ku-CPU. Kwamanye amaphrosesa, afana ne-Kunpeng 920 (ARM) ne-Intel Jacobsville (x86), inombolo ethile yama-CPU cores, ngokuvamile angu-4, angahlanganisa i-L3 noma i-L2 cache.
Kwenziwe izici ezintsha ezimbalwa ezisuselwe kusistimu engaphansi ye-DAMON (I-Data Access Monitor) yengezwe enguqulweni yakamuva, evumela ukulandelela ukufinyelela kudatha ku-RAM, ngokuhlobene nenqubo ekhethiwe esebenza endaweni yomsebenzisi.
Ngaphezu kwalokhu, ukuqaliswa kwe-algorithm yokucindezela zstd ibuyekezelwe kunguqulo 1.4.10, okwenze kwaba nokwenzeka ukukhulisa kakhulu ukusebenza kwe-kernel subsystems esetshenziswa ukucindezela.
Kuphinde kuqashelwe ukuthi ezinye zezindlela ezithuthukisiwe zokuvikela intambo ye-seccomp () ngokumelene nokuhlasela kwe-Specter ziye zacishwa ngokuzenzakalela, ezazibhekwa njengezingafuneki futhi azizange zikhulise kakhulu ukuvikeleka, kodwa zibe nomthelela omubi ekusebenzeni.
I-hypervisor ye-Hyper-V manje isekela imodi yokuhlukanisa yomshini ebonakalayo, ebhala ngemfihlo okuqukethwe yinkumbulo.
Ngenkathi i-hypervisor I-KVM yengeza ukusekelwa kwe-RISC-V yezakhiwo kanye nekhono lokuthutha imishini ebonakalayo ngaphakathi kwendawo yokusingatha laqaliswa kusetshenziswa izandiso ze-AMD SEV kanye ne-SEV-ES, kanye ne-API eyengeziwe yokuthuthela bukhoma kwe-AMD SEV (Secure Encrypted Virtualization) izihambeli ezibethelwe.
Ngokwakheka kwe-PowerPC, imodi ye-STRICT_KERNEL_RWX ivulwa ngokuzenzakalelayo, evimba ukusetshenziswa kwamakhasi enkumbulo atholakala kanyekanye ukuze abhalwe futhi asetshenziswe.
Ekugcineni ngasohlangothini lwabalawuli, ukusekelwa kokuqala kwe-DP 2.0 kwethulwa ku-amdgpu (I-DisplayPort 2.0) kanye ne-DisplayPort idonsa nge-USB4, kwengezwe ukusekelwa komshayeli wesibonisi se-APU Cyan Skillfish nokusekelwa okunwetshiwe kwe-APU Yellow Carp.
Isilawuli I-i915 iqinisa ukuhambisana nama-Intel Alderlake S chips futhi isebenzisa ukusekelwa kobuchwepheshe be-Intel PXP (Protected Xe Path), obukwenza ukwazi ukusingatha iseshini yezithombe ezivikelwe kumasistimu anama-Intel Xe chips.
Kumlawuli nOuveau, umsebenzi wenziwe ukulungisa iziphazamisi nokuthuthukisa isitayela sokubhala amakhodi, ungeze ukwesekwa kwe-Vortex CPU ehambisanayo ne-x86 (Vortex86MX).
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho, ungabheka imininingwane kufayela le- isixhumanisi esilandelayo.
Ngokuqondene nezibuyekezo zale nguqulo entsha, kufanele zifike esikhathini esingamahora / izinsuku eziteshini ezisemthethweni zokusabalalisa kwakho noma ungakhetha ukwenza ukuhlanganiswa ngokwakho ngokuthola ikhodi yomthombo. kusuka kusixhumanisi esingezansi.
