Ukwandisa inani lenguqu enkulu ukuya kwi-5 akuthethi naluphi na utshintsho olukhulu okanye ukuchithwa kokuhambelana. Inceda nje isithandwa sethu uLinus Torvalds ukugcina uxolo lwengqondo. Apha ngezantsi kuluhlu lolunye utshintsho kunye nezinto ezintsha.
Undoqo:
- Umcwangcisi wenkqubo yeCFS kwiiprosesa ze-asymmetric ezifana ne-ARM isebenza ngokwahlukileyo - kuqala ilayisha amandla aphantsi kunye ne-energy cores.
- Ngokusebenzisa i-filetify yefayile yokulandela umkhondo we-API, ungafumana izaziso xa ifayile ivulelwe ukuphunyezwa.
- Umlawuli we-cpuset udibaniswe, ongasetyenziselwa ukunciphisa amaqela eenkqubo ezisekelwe ekusebenziseni i-CPU kunye ne-NUMA nodes.
- Inkxaso yezixhobo ezilandelayo ze-ARM zifakiwe: I-Qualcomm QCS404, i-Allwinner T3, i-NXP/Freescale i.MX7ULP, i-NXP LS1028A, i.MX8, i-RDA Micro RDA8810PL, i-Rockchip Gru Scarlet, i-Allwinner Emlid Neutis N5, kunye nabanye abaninzi.
- Ukuphuculwa kwi-subsystem ye-ARM: i-memory hot-plug, i-Meltdown kunye nokukhusela i-Specter, i-52-bit memory addressing, njl.
- Inkxaso yomyalelo we-WBNOINVD we-x86-64.
Inkqubo esezantsi yememori:
- Ukutshintshwa kwethegi yovavanyo kunye nokusetyenziswa kwememori ephantsi kuyafumaneka kwisixhobo se-KASAN kumaqonga e-ARM64.
- Ukuqhekeka kweememori kuncitshiswe kakhulu (ukuya kuthi ga kwi-90%), okubangele ukuba inkqubo ye-Transparent HugePage isebenze ngcono.
- Ukusebenza kwe-mremap(2) kwiindawo zememori ezinkulu zonyuswe ukuya kutsho kumaxesha angama-20.
- Kumatshini we-KSM, i-jhash2 ithathelwa indawo yi-xxhash, ngenxa yokuba isantya se-KSM kwiinkqubo ze-64-bit sinyuke ngamaxesha angama-5.
- Ukuphuculwa kwe-ZRam kunye ne-OOM.
Vala izixhobo kunye neenkqubo zeefayile:
- Inkqubo ye-blk-mq enenkqubo yemigangatho emininzi yemigca yokucela ibe yeyona iphambili kwizixhobo zebhloko. Yonke ikhowudi engeyo-mq isusiwe.
- Uphuculo kwinkxaso ye-NVMe, ngakumbi malunga nokusebenza kwesixhobo kuthungelwano.
- Kwi-Btrfs, inkxaso epheleleyo yeefayile zokutshintsha iphunyeziwe, kunye nokutshintsha i-FSID ngaphandle kokubhala kwakhona imetadata.
- Umnxeba we-ioctl wongezwe kwi-F2FS ukulungiselela ukujonga okumisiweyo kweFS ngefsck.
- I-Integrated BinderFS - i-pseudo-FS yonxibelelwano lwe-interprocess. Ikuvumela ukuba usebenzise iimeko ezininzi ze-Android kwindawo enye.
- Inani lophuculo kwi-CIFS: i-cache ye-DFS, iimpawu ezongeziweyo, i-protocol ye-smb3.1.1.
- I-ZRam isebenza ngokugqibeleleyo ngezixhobo zokutshintsha ezingasetyenziswanga, igcina inkumbulo.
Ukhuseleko kunye nokusebenza ngokubonakalayo:
- Yongeza umsebenzi we-Streebog hash (GOST 34.11-2012), ephuhliswe yi-FSB yeRussian Federation.
- Inkxaso ye-algorithm ye-Adiantum encryption ephuhliswe nguGoogle kwizixhobo ezinamandla aphantsi.
- Ii-algorithms XChaCha12, XChaCha20 kunye neNHPoly1305 ifakiwe.
- Ukuphathwa kweefowuni ze-seccomp ngoku kunokuhanjiswa kwindawo yomsebenzisi.
- Kwiinkqubo zeendwendwe ze-KVM, inkxaso ye-Intel Processor Trace extensions iphunyezwa ngokuthotywa okuncinci kokusebenza.
- Uphuculo kwindlela esezantsi ye-KVM/Hyper-V.
- Umqhubi we-virtio-gpu ngoku uxhasa ukulinganisa kwe-EDID kwiimonitha ezibonakalayo.
- Umqhubi we-virtio_blk usebenzisa ifowuni yokulahla.
- Kuphunyezwe iimpawu zokhuseleko kwimemori ye-NV esekelwe kwiinkcukacha ze-Intel DSM 1.8.
Abaqhubi besixhobo:
- Utshintsho kwi-DRM API ukuxhasa ngokupheleleyo ulungelelwaniso oluguquguqukayo (inxalenye yomgangatho weDisplayPort) kunye namazinga okuhlaziya aguquguqukayo (inxalenye yomgangatho we-HDMI).
- I-Display Stream Compression standard ibandakanyiwe kuxinzelelo olungenalahleko lwemijelo yevidiyo ebhekiswa kwizikrini ezinesombululo esiphezulu.
- Umqhubi we-AMDGPU ngoku uxhasa i-FreeSync 2 HDR kunye ne-GPU ukusetwa kwakhona kwe-CI, VI, SOC15.
- Umqhubi wevidiyo ye-Intel ngoku uxhasa ii-chips ze-Amber Lake, i-YCBCR 4: 2: 0 kunye ne-YCBCR 4: 4: iifomati ze-4.
- Umqhubi weNouveau uquka umsebenzi kunye neendlela zevidiyo zamakhadi evidiyo ye-Turing TU104 / TU106 yosapho.
- Abaqhubi abadityanisiweyo beRaspberry Pi touchscreen, iiphaneli zeCDTech, Banana Pi, DLC1010GIG, njl.
- Umqhubi we-HDA uxhasa iqhosha elithi "jack", izikhombisi ze-LED, izixhobo zeTegra186 kunye neTegra194.

Inkqubo engaphantsi yenethiwekhi:
- Isitaki se-UDP sixhasa i-zero-copy mechanism yokuhambisa idatha kwisokethi ngaphandle kokuphazamiseka okuphakathi.
- Indlela yeGeneric Receive Offload nayo yongezwe apho.
- Ukuphuculwa komsebenzi wokukhangela kwimigaqo-nkqubo ye-xfrm xa kukho inani elikhulu lazo.
- Ukukwazi ukukhupha iitonela kufakwe kumqhubi weVLAN.
- Inani lophuculo kwinkxaso ye-Infiniband kunye neenethiwekhi ezingenazintambo.
