ULinus Torvalds ubhengeze ukufumaneka kwenguqulelo entsha yeLinux Kernel 5.9 kuluhlu lokuposa. Le yinguqulelo eyazisa izinto ezininzi ezintsha kunye nophuculo, kunye nabaqhubi abatsha ukongeza kuhlaziyo lwabaqhubi.
Uphuhliso lwe-Linux 5.9 kernel lwaqala malunga neenyanga ezimbini ezidlulileyo xa uLinus Torvalds wabhengeza isiganeko sokuqala soMgqatswa woKhupho (RC). Emva kwee-RCs ezingaphantsi kwesibhozo, inguqulelo yokugqibela ye-kernel ngoku iyafumaneka kwaye kufuneka ithunyelwe kwezinye zezona zisasazo zeLinux ezidumileyo kwiiveki ezizayo.
Ngokuphathelele amandla ukusuka kwiLinux 5.9, kukho inkxaso yoyilo lwe-Unicore, inkxaso ye Uxinzelelo lweZstandard (Zsdt) ukuqokelela ii-x86 kernels, inkxaso epheleleyo yemisebenzi yokufunda ii-asynchronous buffers kwindlela esezantsi ye-io_uring, kunye nokhetho olutsha lokuhlangula kunye nophuculo oluninzi lwendlela yefayile ye-Btrfs.
Kukho kwakhona inkxaso yeFSGSBASE x86 imiyalelo, inkxaso yesikhundla somcwangcisi wokugqibela, iqhosha elitsha le-sysctl, Inkxaso yoguqulelo oluntsonkothileyo lwe-EXT4 kunye neesistim zefayile zeF2FS kunye nenkxaso ye-NVIDIA Tegra210 abalawuli beememori zangaphandle kunye nenkxaso ye-Chrome OS eyakhelwe-ngaphakathi yokulawula izilawuli.
Kwakhona, I-Linux 5.9 izisa i close_range () umnxeba wenkqubo entsha, inkxaso ye-Intel "Keem Bay" ye-Movidius VPUs, inkxaso ye-parallel redundancy protocol, inkxaso ye-BPF iterators kwi-TCP kunye ne-UDP sockets, inkxaso yeempawu ezongeziweyo kubathengi be-NFS 4.2, kunye ne-schedutil njenge-CPU engagqibekanga yokulawula i-frequency ye-ARM kunye ne-Arch64 izakhiwo ( I-ARM64).
Kwakhona Inkxaso eyongeziweyo yeebhodi ze-ARM, izixhobo kunye namaqonga avelele: I-Pine64 PinePhone v1.2, Lenovo IdeaPad Duet 10.1, ASUS Google Nexus 7, Acer Iconia Tab A500, Qualcomm Snapdragon SDM630 (isetyenziswa kwi-Sony Xperia 10, 10 Plus, XA2, XA2 Plus kunye ne-XA2 Ultra), Jetson Xavier NTeX , Aspeed EthanolX, iibhodi ezintsha ezintlanu ezisekelwe kwi-NXP i.MX2, MikroTik RouterBoard 6, Xiaomi Libra, Microsoft Lumia 3011, Sony Xperia Z950, MStar, Microchip Sparx5, Intel Keem Bay, Amazon Alpine v5, Renesas RZ / G3H.
Kumaqela, umlawuli omtsha wememori ye-slab uphunyeziwe, ephawuleka ngokuhambisa ubalo lwe slab ukusuka kumphakamo wekhasi lenkumbulo ukuya kumphakamo wento ye kernel, iyenza kube lula ukwabelana ngamaphepha e slab ngapha kwamaqela ahlukeneyo, kunokwabela iingqokelela ze slab ezahlukeneyo kwiqela ngalinye. Indlela ecetywayo ivumela ukwandisa ukusebenza kakuhle kokusetyenziswa kwe, ukunciphisa ubungakanani bememori esetyenziselwa i-slab nge-30-45%, ukunciphisa kakhulu ukusetyenziswa kwememori epheleleyo yi-kernel, kunye nokunciphisa ukuhlukana kwememori.
Ngokumalunga nokuphuculwa kwemizobo, kuyacaca ukuba Umqhubi we-amdgpu wongeza inkxaso yokuqala ye-GPU ye-AMD Navi 21 (Navy Flounder) kunye Navi 22 (Sienna Cichlid). Inkxaso eyongeziweyo ye-UVD/VCE yokufaka ikhowudi yevidiyo kunye neenjini zokukhawulezisa ii-injini zeSouthern Islands GPUs (Radeon HD 7000). Kongezwe ipropathi ukujikelezisa isikrini nge90, 180 okanye 270 degrees.
Kuyathakazelisa ukuba umqhubi we-AMD GPU ungumqhubi omkhulu kwi-kernel: iqulethe malunga ne-2,71 yezigidi zemigca yekhowudi, malunga ne-10% yobukhulu be-kernel (i-27,81 yezigidi zemigca).
Ngelo xesha, imigca ye-1.79 yezigidi kwiifayile zentloko ezenziwe ngokuzenzekelayo kunye nedatha yeerejista ze-GPU, kwaye ikhowudi ye-C i-366 imigca eyiwaka (ukuthelekisa, umqhubi we-Intel i915 uquka i-209 amawaka emigca, kunye ne-Nouveau - i-149 lamawaka).
Umlawuli I-Nouveau yongeza inkxaso yokuhlolwa kwengqibelelo ye-CRC (I-Cyclic Redundancy Checks) isakhelo ngesakhelo kwiinjini zokubonisa ze-NVIDIA GPU. Ukuphunyezwa kusekelwe kumaxwebhu anikezelwe yi-NVIDIA.
Kanjalo, Abaqhubi abaninzi abatsha nabahlaziyiweyo babandakanyiwe kolu lutsha inguqulelo uhlaziyo olukhulu lwe-kernel ukongeza inkxaso yezinto ezintsha zehardware. Ezinye iimpawu ezinxulumene nokhuseleko zikwakhona, kunye nokulungiswa kwebug eqhelekileyo kunye notshintsho lwangaphakathi lwekernel.
Ekugqibeleni, le nguqulelo intsha inokukhutshelwa kusuka kernel.org, ukuba ufuna ukwakha eyakho ikernel. Kwabanye, ungalindela i-Linux kernel 5.9 ezinzileyo ukuba ifikelele kwindawo yokugcina izixhobo zesoftware yonikezelo lwakho lwe-GNU/Linux ngaphambi kokuba uphuculwe kuguqulelo lwangaphambili.
Ngokuphathelele kuguqulelo olulandelayo lweLinux 5.10, kulindeleke ukuba ifike phakathi kuDisemba okanye ngexesha leeholide zeKrisimesi.
