Nooca cusub ee Linux Kernel 4.20 horey ayaa loo sii daayay

Saacado yar kahor iyo Kadib laba bilood oo horumarineed, Linus Torvalds wuxuu ku dhawaaqay nooca cusub ee Linux Kernel 4.20.

Taasi inta udhaxeysa isbeddelada ugu caansan ee noocaan cusub ee Kernel 4.20 Tilmaamo cusub ayaa lagu soo daray, kuwaas oo sixitaanno kala duwan lagu daray dhanka khaladaadka iyo, wixii ka sarreeya, taageerada qalab kala duwan.

Qaabkan cusub ee Linux Kernel 14,997 balastar ayaa laga sameeyay 1857 horumariyayaal si loo helo nooca cusub, Cabbirka balastarku wuxuu ahaa 49MB (isbedellada saameeyay 11,402 faylal, 686,104 sadar oo koodh lagu daray, 318945 khad ayaa laga saaray).

Qiyaastii 47% dhammaan isbeddelada lagu soo bandhigay 4.20 waxay la xiriiraan darawalada qalabka, qiyaastii 17% isbeddelada waxay la xiriiraan cusbooneysiinta koodh gaar ah oo loogu talagalay qaab dhismeedka qalabka dhismaha, 14% waxay la xiriiraan xirmooyinka shabakadda, 3% waa nidaamyo faylal ah iyo 4% waa nidaamyada hoose ee hoose.

Maxaa ku cusub Linux Kernel 4.20?

Soosaariddan cusub, waxaad ku taageertaa naqshadaha processor-ka C-SKY ayaa lagu daray sidoo kale jadwalka taraafikada taraafikada, PSI (macluumaadka xannibaadda cadaadiska) subsystem, P2P DMA ee PCI.

Ka sokow waxae wuxuu ku daray sumadda farsameynta farsameynta, isku xirka dissectors network gudbinta kaydka ee qaabdhismeedka cusub ee XArray, isku darka darawalada amdgpu iyo amdkfd, kordhinta waxqabadka nidaamka 'FUSE subsystem', awood u lahaanshaha shaandheynta xirmooyinka shabakadaha ee ku saleysan astaamaha sumadda, taas oo u oggolaaneysa sumcad-darrida KVM.

Speck wuu baxay

Muranka Speck ee dhowaan lagu daray Linux 4.17 ee algorithm encryption Kernel ayaa laga saaray Linux 4.20.

Tan iyo markii Google laga xayuubiyay kalsoonida koodhka dhabta ah ee loogu talagalay Android. Tani ma ahayn mid ku timid tikniyoolajiyadda, maadaama algorithm-ka ay soo saartay NSA.

Jaangoynta tan ayaa la diiday, maadaama NSA aysan rabin inay ka jawaabto su'aalaha faahfaahsan ee ku saabsan algorithm.

Sidoo kale, awoodsiinta waxaa lagu xoojiyay KVM, taas oo hadda awood u siineysa mashiinnada farsamada iyada oo loo marayo hufnaan ku dhex jirta mashiin dalwaddo ah.

Taageero ayaa sidoo kale loo heli karaa Raspberry Pi Model 3. Mustaqbalka, isdabajooga TCP wuxuu geyn doonaa xirmooyin algorithm cusub, kaas oo ah inuusan aheyn inuu ahaado mid dhaqso badan laakiin sidoo kale amaan badan.

Hab maamuusyo cusub

Jadwaliye cusub oo "taprio" taraafik ah ayaa lagu hirgeliyay xaruntan, taas oo u oggolaanaysa maareynta dirista baakadaha sida ku xusan taxanaha waqtiga ee horay loo soo saaray.

Habka jadwalka ayaa lagu qeexay qeexitaanka IEEE 802.1Qbv, wuxuu tixgelinayaa shuruudaha gudbinta taraafikada waqtiga xasaasiga ah ee loogu talagalay gudbinta baakadka (tusaale ahaan, fiidiyowga iyo durdurrada maqalka), wuxuuna u adeegsadaa waqtiyo kala duwan fasallo kala duwan oo taraafikada ah.

Nidaamka rtnetlink, hab hubin adag ayaa la hirgeliyaa ("Hubinta adag"), taas oo hubinaysa in macluumaadka ku habboon loo gudbiyo goobta isticmaalaha ee u dhiganta codsiga soo socda;

Lagu daray awooda lagu sifeeyo qashin qubka macluumaadka marinka hab maamuuska loo isticmaalo (tusaale ahaan, in laga sooco dariiqyada kala duwan ee loo yaqaan 'daemons'), noocyada waddooyinka (tusaale ahaan, in lagu meeleeyo unicast)

Aqoonsiga miiska wadada iyo marinka ugu dhow (nexthop).

Shaandheeyeyaasha noocan oo kale ah ayaa muddo dheer lagu taageeray iproute2, laakiin waxaa lagu hirgeliyay goobta isticmaalaha. U guurista miirayaasha booska kernel waxay kuu oggolaaneysaa inaad kordhiso waxtarka nidaamyada hagidda ee ku saleysan Linux-ka waaweyn.

In hirgelinta isku xirnaanta shabakadda (buundo hoosaad), awoodda lagu arki karo tirakoobka VLAN ee ku saabsan macnaha guud ee dekedaha shaqsiga ah ayaa lagu daray;

Taageerada 5 iyo 6 kanaal ee loogu talagalay 60 GHz band ayaa lagu daray ieee80211 wireless wireless, iyo sidoo kale awooda lagu awood siinayo waxqabadka FTM Responder ee goobta isticmaalaha.

Iyo Kernel 5.0 goorma?

Ugu dambeyntii, qaar badan ayaa filayay in kernel-ka cusub uu lamid noqon doono isbeddelka ilaa 4.0 tan iyo wixii ka dambeeyay 4.19 nooca 5.0 ayaa hadda la filayaa.

Si kastaba ha noqotee, maadaama Torvalds uusan rabin in lagu xalliyo qorshe, waxaa la sheegay in Linux 5.0 uu imaan doono 2019. In kasta oo taariikhda la qiyaasay aan la ogeyn, maadaama xilligan la joogo qorshayaasha nooca xiga ay ku sii socdaan nooca 4.21.
