Ezinsukwini ezimbalwa ezedlule ILinus Torvalds imemezele ukutholakala kwenguqulo ezinzile yeLinux 5.14 lapho ukusekelwa kohlelo lwe-kernel kuqokonyisiwe, ukusekelwa kwezindawo zememori eyimfihlo nge MEMFD_SECRET, ukuxhaswa okuqhubekayo kwamakhadi wehluzo we-AMD Alder Lake, i-Yellow Carp ne-Beige Goby, ukusekelwa kwama-laptops e-AMD SmartShift, ukuxhaswa kweRaspberry Pi 400, phakathi kwezinye izinto ezivelayo.
I-Linux 5.14 ifike ngesikhathi esikhethekile, kusukela umgubho weminyaka engama-30 nakho kwagujwa selokhu umdali uLinus Torvalds aqale ukumemezela esidlangalaleni iLinux. Ngalesi sikhathi, iLinux isuke ekubeni yinto yokuzilibazisa yaba yingqalasizinda ye-Intanethi.
ULinus Torvalds ubhale kwisimemezelo seLinux 5.14:
“Ngiyabona ukuthi wonke umuntu kumele abe matasa ngayo yonke imidanso kanokusho nokuhlobisa nayo yonke eminye imicimbi yokugubha iminyaka engama-30, kodwa kwesinye isikhathi kumele ukuthi ukhathele. Kucwebezela njalo, iziqhumane kanye ne-champagne.
“Leya ngubo yebhola noma lowo msila we-magpie nawo awukhululekile kakhulu. Imikhosi izohlala amasonto ambalwa, kepha kungadingeka ukuthi uphefumule kancane. Futhi lapho lokho kwenzeka, nginakho okudingayo: inguqulo entsha ye-kernel ukuzama nokuyijabulela. I-Version 5.14 isilapha, ilinde wena nje ukuthi uyizame futhi ikukhumbuze ngenhloso yayo yonke le mikhosi, "engeza.
Izici ezintsha eziyinhloko zeLinux 5.14
Njengenjwayelo, I-Linux 5.14 iza nenqwaba yokuthuthuka nezici ezintsha. Kwezinguquko ezibaluleke kakhulu ngokungangabazeki memfd_secret nokuhlela okuphakathi ngoba womabili umsebenzi wokuhlanza uyaqhubeka ukunciphisa ubungozi be-Intel's Specter neMeltdown.
Ngokwengxenye yayo i-memfd_secret ivumela izinhlelo zokusebenza ukuthi zenze indawo yememori engafinyelelwa yilolu hlelo lokusebenza kuphela. Ngisho ne-kernel ayikwazi ukufinyelela endaweni yememori ekhethiwe. Okubalulekile, ngoba iSpecter neMeltdown bekusho ukuthi idatha efinyelelwe ingafinyelelwa, i-memfd_secret yakhelwe ukuhlinzeka indawo ephephile yokhiye be-cryptographic noma amaphasiwedi.
Ngokuqondene ne ikhodi entsha yokuhlela eyinhloko, lokhu kubalulekile, futhikuleyo yezindlela zokunciphisa iSpecter neMeltdown kwakuwukukhubaza i-hyperthreading. I-Linux manje usungakwazi ukunika amandla i-hyperthreading kahle futhi siqinisekise ukuthi umthwalo omningi onokwethenjelwa futhi onokwethenjelwa awabelani nge-kernel futhi udala izingozi ezifana nalezo ze-Specter.
Esinye isici esisha ku-Linux 5.14 yi- Ukuvuselelwa kuhloswe kakhulu kubasebenzisi be-hyperscale, Ngaphandle kwalokho ye-Intel kernel version 5.14 ingeza ukusekelwa okwengeziwe kwepulatifomu ye-Alder Lake Chipzilla, lokho kubeka izinhlobo eziyisisekelo eziningi ku-chip eyodwa futhi kubeka phambili umthwalo, plus usebenzisa i-Intel TSX (Izandiso Zokuvumelanisa Okwenziwayo) ikhutshazwe ngokuzenzakalela, Lokhu kunikeza izindlela zokwenza ngcono ukusebenza kwezicelo ezifundwa ngokuqedwa ngamandla kokusebenza kokuvumelanisa okungadingekile. Izandiso zikhutshaziwe ngenxa yokuthi kungenzeka kwenzeke ukuhlaselwa kweZombieload.
Kuyaziwa futhi ukuthi ukwesekwa kokwakhiwa kwe-RISC-V kwenziwa ngcono, manje esekhIkuvumela ukuthi ube nokufinyelela okungcono kweminye imisebenzi ebalulekile ye-kernel, njengokusebenza kwemephu yokukhumbula.
Futhi, ukufakwa kwe-SimpleDRM kuthuthukisa ukuphatha kwe-GPU (I-DRM imele iMenenja Eqondisa Ngqo kuleli cala). Ngokwengxenye yayo, uDell unikeze umshayeli ukuthi akhubaze ama-webcam namakhrofoni ezingeni lehadiwe, ukuze kusebenze ukushintshwa kokuma noma inhlanganisela yokhiye eyenza okufanayo kwamanye ama-laptops ayo.
Ngokuqondene ne izithuthukisi zomsindo kule nguqulo umshayeli we-USB obambezelekile ufakiwe, umshayeli omusha wehlisa ukubambezeleka ngesikhathi sokudlala komsindo futhi usetshenziswe nePulseAudio, JACK, nePipeWire, kanye Ama-codecs alalelwayo eRockchip RK817 neQualcomm WCD9380 / WCD9385 afakiwe.
Phakathi kwengcebo yokwesekwa kwehadiwe ikhodi yokuphatha ukushintshwa kwenethiwekhi ye-Sparx5, izinzwa ze-Sony IMX208, nezindawo zokuthokozela zeSparkFun Qwiic, kanye neLinux 5.14 iza nokuxhaswa okuphelele kwe-kernel kweRaspberry Pi 400.
Ekugcineni, kunomzamo oqhubekayo wokwengeza ukwesekwa kwe-Linux kubuchwepheshe obusha nobusafufusa, kufaka phakathi i-USB 4 ne-AMD Beige Goby & Yellow Carp amakhadi emidwebo.
Uma ufuna ukwazi okwengeziwe ngale nguqulo entsha, unga hlola imininingwane kusixhumanisi esilandelayo.
