Linus Torvalds da tawagarsa na ci gaba ba su daina ƙoƙarinsu ba don ci gaba tare da ci gaban Linux Kernel duk da matsalolin da na san yanzu suna fuskantar duniya saboda Covid-19.
Kuma wannan ma haka ne Na san yana aiki kan sakin dan takarar don sabon sigar da Kernel 5.6, Har ila yau, tuni yana aiki akan na gaba 5.7 cewa idan komai ya ci gaba akan tafiyar zamu ga an sake shi a wannan bazarar.
Ingantawa don ƙananan kalmomi
Kuma wannan shine game da wannan sabon sigar na Linux Kernel 5.7 da masu haɓaka tsarin tacewa da gyarawa Fakitin yanar gizo na Netfilter sanar ta hanyar sanyawa saitin faci wanda ke saurin saurin sauri aiki na manyan kayan kwalliya, waɗanda ke buƙatar tabbatar da haɗin ƙananan subnets, tashar tashar sadarwa, yarjejeniya, da adiresoshin MAC.
An riga an karɓi facin a cikin reshen nf-na gaba, wanda za'a gabatar dashi don sakawa a cikin kernel na Linux 5.7. An sami mafi saurin hanzari ta hanyar amfani da umarnin AVX2 (kwatankwacin irin waɗannan abubuwa bisa ga umarnin NEON don ARM ana shirin buga su a nan gaba).
Inganci aka gabatar a cikin koyaushe nft_set_pipapo (Takaddun PIle PAcket), wanda ke magance matsalar kwatancen abun cikin fakiti tare da jeri na filayen jihar da ake amfani da su a cikin dokokin tacewa, kamar su IP da tashar tashar jiragen ruwa (nft_ kafa_rbtree da nft_set_hash yi amfani da aikin tazara da kuma nuna ƙima kai tsaye).
An ƙaddara shi tare da umarnin AVX2-bit 256-bit, sigar pipapo akan tsarin tare da mai sarrafa AMD Epyc 7402 ya nuna ƙaruwar aiki 420% yayin nazarin rajista 30 waɗanda suka haɗa da fakitin yarjejeniya ta tashar jiragen ruwa.
Inara kwatancen ƙananan fakiti da lambar tashar jiragen ruwa yayin nazarin abubuwan shigarwa 1000 ya kasance 87% na IPv4 da 128% don IPv6.
Wani ingantawa, wanda ke ba da damar amfani da rukunin taswira 8-bit maimakon na 4-bit, Har ila yau, ya nuna karuwar aikin haɓaka: 66% yayin nazarin shigarwar tashar tashar tashar jiragen ruwa dubu 30, 43% - subv tashar IPv4 da 61% - tashar tashoshin IPv6.
Gabaɗaya, ɗaukar abubuwan inganta AVX2 cikin lissafi, aikin pipapo ya haɓaka cikin waɗannan gwaje-gwajen da kashi 766%, 168%, da 269%, bi da bi.
Abubuwan halaye da aka samo don kwatancen masu rikitarwa suna gaba da bincika filayen kowane mutum a cikin rbtree (ban da tashar tashar jiragen ruwa + yarjejeniya mai ɗaurewa), amma ya zuwa yanzu suna bayan binciken kai tsaye ta hanyar amfani da toshe da masu sarrafa abubuwa.
NVMe SSD kayan haɓakawa
Wani daga canje-canjen da zai kasance tare da Linux 5.7 Kernel shine haɓakawa don saurin bugun tsarin daga NVMe SSD. Shi ke nan godiya ga mai haɓaka Intel Josh Triplett, wanda ya nuna cewa lokacin da za a iya ganin idan nvme boot drive ya shirya don amfani shi ne 100ms. Tunda NVME SSDs yawanci suna da sauri, Triplett canza lokacin aiki daga milliseconds 100 zuwa 1 ms.
A cewar mai haɓakawa, wannan ya sami kusan sakan 0.2 a lokacin farawa. Kodayake wannan ba ya haifar da babban banbanci ba, amma tabbas ka'ida ce 'kowane ɗan ƙidaya'.
Hakanan, cewa sakan 0.2 na iya zama mahimmanci a wasu aikace-aikacen, kamar saitin inji mai kama da tsari ko kyamara waɗanda ke buƙatar kasancewa a shirye su harba kusan nan da nan.
ExFAT direban tsarin fayil
Arshe amma ba mafi ƙaranci ba, wani sabon labarin wanda zamu iya samu a Linux 5.7 shine sabon direban tsarin fayil na exFAT, wanda yanzu zai ba da babban tallafi ga direba wanda ke cikin Kernel a yanzu, tunda sigar yanzu tana da iyaka saboda ta dogara ne da wani tsohon direba.
Sabon mai sarrafawa wanda za'a haɗa zai kasance wanda Samsung ke aiki dashi, yana ba da damar yin aiki tare da manyan hanyoyin da aka tsara ta amfani da tsarin fayil na exFAT. Sabon direban za'a san shi da suna EXFAT_FS, amma tsohon direban rikon kwarya (CONFIG_STAGING_EXFAT_FS) ba zai tafi ba tukunna. Da farko matukan jirgin biyu za su rayu kusa da juna, amma wannan ba zai zama haka ba har abada.
