Ezinsukwini ezithile ezedlule U-Linus Torvalds umemezele ukutholakala okujwayelekile kwenguqulo ezinzile ye-Linux 5.18, inguqulo efika ngemva kwezinyanga ezimbili ngokuqondile ngemva kochungechunge lwe-Linux 5.17 kernel futhi yathola izigaba eziyisishiyagalombili ze-RC (Release Candidate) kuwo wonke umjikelezo wayo wokuthuthuka, osize abathuthukisi be-kernel balungise iziphazamisi futhi bathuthukise izici ezikhona.
Phakathi kwezinguquko ezifanele kakhulu zale nguqulo entsha ye-Linux Kernel 5.18 ihlanganisa ukuguqulwa kwesilinganiso sokuhlanganisa i-C11, ukusekelwa "kwemicimbi yabasebenzisi" ohlelweni lokulandela umkhondo, ukusekelwa komsebenzi "we-host system management port" kusuka ku-AMD, ukusekelwa kwe-64 -bit ubuqotho checksums kumadivayisi e-NVMe, nokuningi.
Izici ezintsha eziyinhloko zeLinux 5.18
Izengezo eziningi ezivela ku-Intel zenziwe kule nguqulo entsha ye-Linux Kernel 5.18, kufaka phakathi i- umshayeli omusha “I-Hardware Feedback Interface” (I-HFI) yamaphrosesa ayingxube afana ne-Alder Lake, i-"Software Defined Silicon" (SDSi) ihlanganisiwe ukuze kunikwe amandla izici ze-silicon ezinelayisense ye-Intel CPUs yesikhathi esizayo, i-"Intel Indirect Branch Tracking" (IBT) njengengxenye ye-"Control-Flow Enforcement Technology". ”, “ENQCMD” inikwe amandla kabusha ku-Sapphire Rapids nokunye. I-Intel PECI, i-Platform Environmental Control Interface, nayo yahlanganiswa ukuze kuxhunywe i-CPU ne-BMC kumapulatifomu eseva ye-Intel.
I-Los amalungiselelo e-Intel IPI virtualization nawo afika ku-Linux 5.18, ngenkathi ukwenza kusebenze kwangempela kufanele kube khona kumjikelezo we-v5.19. Ngokuqondene ne-Intel entsha endaweni yehluzo, i-Linux 5.18 inikeza ukusekelwa kwe-DG2 G12 sub-platform, ukusekelwa kwehluzo ze-Intel Alder Lake N kanye ne-DG2/Alchemist ehlukahlukene inika amandla izingcezu.
Kuphinde kube nomsebenzi ku-AMD EDAC kuma-CPU weZen 4, ukuthuthukiswa kokubonwayo okufakwe esidlekeni kusuka ku-AMD nomunye umsebenzi ku-Zen 4. I-KVM ene-Linux 5.18 iphinde ihambisane nemishini ebonakalayo ye-AMD kufika kuma-vCPU angu-511, isuka ku-255 vCPU namuhla, futhi idlula isizukulwane sakamuva se-EPYC. amaseva anikeza inani eliphakeme lama-cores ane-Bergamo. Ngokuqondene nemidwebo ye-AMD, i-Linux 5.18 inika amandla "imodi yevidiyo" ye-AMDGPU's FreeSync ngokuzenzakalelayo, ebifihliwe ngemuva kwenketho yemojula kuma-kernel adlule.
Amabhulokhi okuqala e-IP nawo anikwe amandla kuma-GPU nama-APU isizukulwane esilandelayo, kodwa okuningi kuhlelwa ku-kernel 5.19. Mayelana ne-hardware, i- "I-Raspberry Pi Zero 2W" inokusekelwa okugcwele kwe-Linux kernel kule nguqulo.
Ngaphezu kwalokho, isistimu yefayela ye-ReiserFS ihoxisiwe futhi kulindeleke ukuthi isuswe ngo-2025. Ukuhoxiswa kwe-ReiserFS kuzonciphisa umzamo odingekayo ukuze kugcinwe izinguquko zesistimu yefayela evamile ukuze kusekelwe ama-mount, iomap, nama-API wevolumu entsha.
Kubuye kuqhakanjiswe lokho ikhodi yokubala yezibalo isiklanywe kabusha kumashayeli emephu yedivayisi, okuthuthukise kakhulu ukunemba kwezibalo kubashayeli abafana ne-dm-crypt. Kumadivayisi e-NVMe, usekelo lwamasheke angama-64-bit wokuhlolwa kobuqotho selusetshenzisiwe.
Ngakolunye uhlangothi, kugqanyiswa ukuthi ukuhlanganiswa kwesethi yamapeshi sekuqalile, okunganciphisa kakhulu isikhathi sokwakha kabusha i-kernel ngokuhlela kabusha isigaba samafayela anhlokweni kanye nokunciphisa inani lokuncika okuphambene. I-Kernel 5.18 ifaka amapeshi athuthukisa ukwakheka kwamafayela eheda yesihleli (i-kernel/sched).
Ikhodi ye-kernel ingasebenzisa i-C11 ejwayelekile, ishicilelwe ngo-2011. Ngaphambilini, ikhodi engezwe ku-kernel bekumele ihambisane nencazelo ye-ANSI C (C89), eyakhiwa ngo-1989. Kushintshwe inketho ye-'–std=gnu89' yaba ngu-'–std=gnu11 -Wno-shift- negative. -value' kumbhalo wokwakha we-5.18 kernel. Amathuba okusebenzisa izinga le-C17 aye acatshangelwa, kodwa kulesi simo kuzodingeka ukuthi kwandiswe ubuncane benguqulo esekelwe ye-GCC, kuyilapho ukufakwa kokusekelwa kwe-C11 kuvumelana nezidingo zamanje zenguqulo ye-GCC (5.1).
Futhi Amathuluzi anwetshiwe okulandelela izinhlelo zokusebenza esikhaleni somsebenzisi agqanyisiwe. Inguqulo entsha ye-kernel yengeza amandla ezinqubo zomsebenzisi ukudala imicimbi yomsebenzisi nokubhala idatha ku-trace buffer, engabukwa ngezinto ezijwayelekile zokulandela i-kernel ezifana ne-ftrace ne-perf.
Okokugcina, uma ungathanda ukwazi okwengeziwe ngakho, ungathintana nemininingwane ku isixhumanisi esilandelayo.
