Emva kweenyanga ezimbini zophuhliso, ILinus Torvalds ivelise ukukhutshwa kweLinux Kernel 5.0. Kwangelo xesha, Isiseko seSoftware yasimahla yeLatin America senze uguqulelo olukhululekileyo lweKernel 5.0: Linux-free 5.0-gnuNgaphandle kwezinto ze-firmware okanye abaqhubi abanamacandelo ekhowudi engahlawulelwayo okanye izinto, umda wazo unqunyelwe ngumenzi.
Entre Olona tshintsho lubalulekileyo kwi-Kernel 5.0 kukudityaniswa kwe-Android enkulu esekwe kwi-ARM. Inkxaso yetekhnoloji yeFreeSync kumqhubi we-AMDGPU nokunye okuninzi.
Izinto eziphambili ezenziwayo zeKernel 5.0
Phakathi kolona tshintsho lubalulekileyo kwiKernel 5.0 sifumana ukongezwa kwendlela yokubhala ye-Adiantum yefayile iphuhliswe nguGoogle, enokusetyenziswa kwizixhobo ezinamandla asezantsi athi, ngenxa yokugcwala kakhulu, ayinakho ukusebenzisa i-AES block encryption algorithm.
Ukuphunyezwa kweAdiantum ixhomekeke ekusebenziseni ngokukhawuleza kwe-NH umsebenzi we-hash, i-Poly1305 (MAC) yokuqinisekisa umyalezo we-algorithm, kunye ne-XChaCha12Kunye nokusebenza okukodwa okusekwe kwi-AES-256 block encryption ye-16 byte kwibloko nganye.
I-Adiantum yongezwe kwinkqubo esezantsi ye-fscrypt, Isetyenziselwa ukufihla ngokufihlakeleyo iifayile kunye nemikhombandlela kwi-ext4, f2fs, kunye neenkqubo zeefayile ze-ubif.
Elinye inqaku esinokuthi siliqaqambise kolu khululo ngu umqhubi we-AMDGPU owongeze inkxaso yeTekhnoloji yokuvumelanisa eFreeSync (VESA Adaptive-Sync), ekuvumela ukuba uhlengahlengise inqanaba lokuhlaziya ulwazi kwiscreen sokujonga ukuqinisekisa ixesha elincinci lokuphendula, ukuphuma kakuhle, kwaye akukho siphazamiso ngexesha lemidlalo kunye nevidiyo.
IFreeSync ikwavumela ukuba unciphise ukusetyenziswa kwamandla ngokunciphisa amandla okuhlaziya xa umfanekiso okwisikrini ungatshintshi.
Kule Kernel 5.0 yokukhutshwa kwenkxaso yoluhlu lweememori zeNVM kongezwa ngemisebenzi yokhuseleko eyakhelwe-ngaphakathi njengokukhuselwa kwephasiwedi, ukucoca kunye nokutshixa.
Inxalenye edityanisiweyo yesiqwengana ukuvala izithuba kunye nokuphepha i-UEFI Safe Boot.
Kule nqanaba, izixhobo zongezwe ukulawula ukusetyenziswa kwe-kexec_load_file () inkqubo yefowuni, enokusetyenziselwa ukudlula kwi-UEFI Boot ekhuselekileyo ngokutshintsha iKernel evavanyiweyo yenye iKernel engatyikitywanga ngokwamanani.
Disk subsystem, I / O, kunye neefayile zenkqubo
Wongeze amandla okutshintsha izahlulelo kwiifayile ngaphakathi kwenkqubo yefayile yeBtrfs. Ifayile yokubheja kwii-Btrfs kufuneka igcwaliswe ngokupheleleyo kwimowudi ye "nocow" ngaphandle kokusebenzisa ucinezelo kwaye ibekwe kwidrive enye kuphela.
Inkqubo esezantsi yenethiwekhi
Kwi-UDP, ukukwazi ukuthumela idatha kwisokethi yenethiwekhi kuphunyezwa kwimowudi yekopi zero (thumela umnxeba ngeflegi yeMSG_ZEROCOPY), evumela ukuhanjiswa kwedatha kuthungelwano ngaphandle kokugcina okuphakathi.
Isitaki se-UDP sisebenzisa inkxaso esisiseko ye-GRO (iGeneric Receive Offload) ukuxhasa ukukhawulezisa inani elikhulu leepakethi ezingenayo, ukongeza iipakethi ezininzi kwiibhloko ezinkulu ezingadingi kuqhutywa ngokwahlukeneyo kwepakethi nganye.
Imemori kunye neenkonzo zenkqubo
Imowudi entsha yokucwangciswa kwemisebenzi iphunyeziwe yeeprosesa ze-asmmetric ARM esekwe kuyilo olukhulu, edibanisa amandla, kodwa amandla, ii-cores ze-CPU kunye nemveliso encinci, kodwa ngakumbi amandla asebenzayo.
Imowudi entsha iya kuthi ivumela ukunciphisa ukusetyenziswa kwamandla ngenxa yemisebenzi yokuvuka ikakhulu kwi-CPU cores.
Kwelinye icala, inkxaso yemiyalelo yeprosesa ye-WBNOINVD yongezwa, yaphunyezwa kwi-AMD nakwiiprosesa ze-Intel ngokusekwe kuyilo lwe-x86_64. Isiteyitimenti esikhombayo siguqula onke amajelo e-cache atshintshiweyo kuwo onke amanqanaba emibutho ye-cache ngememori ephambili, ngelixa kugcinwa amaxabiso agciniweyo kwi-cache.
Uyifumana njani iKernel 5.0?
I-5.0 kernel iyafumaneka ukuze ikhutshelwe ngokuthe ngqo kernel.org ukuba ufuna ukuzihlanganisa ngokwakho.
Nangona izakufumaneka nakusasazo lwakho lweLinux kwiintsuku ezizayo.
