ULinus Torvalds umemezele ukutholakala kwenguqulo entsha ye-Linux kernel engu-5.9 ohlwini lweposi. Le nguqulo ifaka izici ezintsha eziningana kanye nokuthuthukiswa, kanye nabashayeli abasha kanye nezibuyekezo zabashayeli.
Ukuthuthukiswa kwe-Linux 5.9 kernel kwaqala cishe ezinyangeni ezimbili ezedlule lapho uLinus Torvalds ememezela ingqophamlando yokuqala ye-Release Candidate (RC). Ngemuva kwama-RC angaphansi kwesishiyagalombili, inguqulo yokugcina ye-kernel isiyatholakala futhi kufanele ithunyelwe kokunye ukusatshalaliswa kweLinux okuthandwa kakhulu emasontweni azayo.
Ngokuphathelene namandla e-Linux 5.9, kukhona ukwesekwa kwe-Unicore architecture , ukwesekwa kwe -Zstandard compression (Zsdt) yokuhlanganisa ama-kernel e-x86, ukwesekwa okugcwele kwemisebenzi yokufunda i-buffer engavumelani ohlelweni olungaphansi lwe-io_uring, kanye nenketho entsha yokusindisa kanye nokuthuthukiswa kokusebenza okuningana kohlelo lwefayela le-Btrfs.
Kukhona futhi ukwesekwa kwemiyalelo ye-FSGSBASE x86, ukwesekwa kwamandla kweshejuli yosuku lokugcina, inkinobho entsha ye-sysctl, ukwesekwa kokubethela okuqondile kwezinhlelo zamafayela ze-EXT4 ne-F2FS , kanye nokusekelwa kwabalawuli bememori bangaphandle be-NVIDIA Tegra210 kanye nokusekelwa kwabalawuli abahlanganisiwe be-Chrome OS.
Ngaphezu kwalokho, i-Linux 5.9 iletha ucingo olusha lwesistimu ye-close_range() , ukwesekwa kwama-Intel “Keem Bay” Movidius VPU, ukwesekwa kwephrothokholi ye-parallel redundancy, ukwesekwa kwama-iterators e-BPF kuma-socket e-TCP kanye ne-UDP, ukwesekwa kwezimfanelo ezinwetshiwe zamaklayenti e-NFS 4.2, kanye ne-schedutil njengomlawuli wemvamisa ye-CPU ozenzakalelayo wezakhiwo ze-ARM kanye ne-AArch64 (ARM64).
Ngaphezu kwalokho, igqamisa nokusekelwa okwengeziwe kwamabhodi e-ARM, amadivayisi, kanye namapulatifomu: I-Pine64 PinePhone v1.2, i-Lenovo IdeaPad Duet 10.1, i-ASUS Google Nexus 7, i-Acer Iconia Tab A500, i-Qualcomm Snapdragon SDM630 (esetshenziswa ku-Sony Xperia 10, 10 Plus, XA2, XA2 Plus, kanye ne-XA2 Ultra), i-Jetson Xavier NX, i-Amlogic WeTek Core2, i-Aspeed EthanolX, amabhodi amasha amahlanu asekelwe ku-NXP i.MX6, i-MikroTik RouterBoard 3011, i-Xiaomi Libra, i-Microsoft Lumia 950, i-Sony Xperia Z5, i-MStar, i-Microchip Sparx5, i-Intel Keem Bay, i-Amazon Alpine v3, kanye ne-Renesas RZ/G2H.
Kumaqembu e-c, kusetshenziswa isilawuli sememori esisha se-slab , esiphawulekayo ekudluliseni ukubalwa kwe-slab kusuka ezingeni lekhasi lememori kuya ezingeni lento ye-kernel. Lokhu kwenza kube nokwenzeka ukwabelana ngamakhasi e-slab kuwo wonke amaqembu e-c, esikhundleni sokwabela ama-slab cache ahlukene eqenjini ngalinye le-c. Indlela ehlongozwayo yandisa ukusebenza kahle kokusetshenziswa kwe-slab , inciphisa inani lememori elisetshenziswa kuma-slab ngo-30–45%, inciphisa kakhulu ukusetshenziswa kwememori ye-kernel iyonke, futhi inciphisa ukuhlukana kwememori.
Ngokuphathelene nokuthuthukiswa kwehluzo, umshayeli we-amdgpu unezela ukwesekwa kokuqala kwe-GPU kwe-AMD Navi 21 (Navy Flounder) kanye ne-Navi 22 (Sienna Cichlid). Ukusekelwa kwezinjini zokusheshisa zevidiyo ze-UVD/VCE kanye nokukhipha ikhodi kungeziwe kuma-Southern Islands GPU (Radeon HD 7000). Isici esivumela isikrini ukuthi sijikelezwe ama-degree angu-90, 180, noma angu-270 naso sengeziwe.
Kuyathakazelisa ukuthi umshayeli we-AMD GPU umshayeli omkhulu kunabo bonke ku-kernel - iqukethe cishe imigqa yekhodi eyizigidi ezingama-2,71, okucishe kube ngu-10% wosayizi ophelele we-kernel (imigqa eyizigidi ezingama-27,81).
Ngasikhathi sinye, imigqa eyizigidi eziyi-1.79 isemafayeleni enhlokweni akhiqizwa ngokuzenzakalela anedatha yamarejista we-GPU, futhi ikhodi ye-C ingamakhilomitha ayizinkulungwane ezingama-366 (uma kuqhathaniswa, isilawuli se-Intel i915 sifaka imigqa eyizinkulungwane ezingama-209 neNouveau - 149 XNUMX ).
Umshayeli we-Nouveau unezela ukwesekwa kokuqinisekiswa kobuqotho be-CRC (Cyclic Redundancy Checks) ku-NVIDIA GPU display engines. Ukuqaliswa kusekelwe kumadokhumenti anikezwe yi-NVIDIA.
Vele, abashayeli abaningi abasha nababuyekeziwe bafakiwe kulokhu kukhishwa kwe -kernel entsha enkulu ukuze bangeze ukwesekwa kwezingxenye ezintsha zehadiwe. Ezinye izici ezihlobene nokuphepha nazo zikhona, kanye nokulungiswa kwamaphutha okuvamile kanye nezinguquko zangaphakathi ze-kernel.
Okokugcina, le nguqulo entsha ingalandwa kusuka ku-kernel.org uma ufisa ukwakha i-kernel yakho. Kwabanye, ungalinda ukuthi i-kernel 5.9 ye-Linux ezinzile ikhishwe ezindaweni zokugcina isofthiwe ezizinzile zokusatshalaliswa kwe-GNU/Linux ngaphambi kokuthuthukisa kusuka kunguqulo yangaphambilini.
Ngokuqondene nenguqulo elandelayo yeLinux 5.10, kulindeleke ukuthi ifike maphakathi noDisemba noma ngesikhathi samaholide kaKhisimusi.
