Ukuba emva Malunga neZombieLoad Ukuba usothukile ucinga ukuba ungayicima njani into ye-Intel's Hyper-Threading ukunqanda ukuxhatshazwa kobuthathaka obutsha obufana neSpecter kunye neMeltdown, emva koko uthathe umoya onzulu-isikhokelo esisemthethweni se-Intel asikukhuthazi ukwenza oku uninzi. iimeko.
I-ZombieLoad iyafana nohlaselo lwangaphambili lwetshaneli enyanzela abaqhubekekisi be-Intel ukuba baveze ulwazi olunovakalelo olunokuthi lube lodwa kwaye lufikeleleke kuphela kwizicelo ezilusebenzisayo. Abaphandi bokhuseleko baye baxela ngaphambili ukuba ubuthathaka bukhona kwiitshiphusi ezininzi ze-Intel kwaye zinokusetyenziswa kwiWindows, MacOS kunye neLinux.
I-Intel, ngenxalenye yayo, ayihambisani nendlela umngcipheko weZombieLoad uvavanywa ngayo. Inkampani yade yagqiba ukunika iZombieLoad igama elahlukileyo - iSampuli yeDatha yeMicroarchitectural (MDS) okanye iSampuli yeDatha yeMicroarchitectural. Vuma, oku kuvakala kuncinci ukoyikeka kunokubhekisa kwezinye zombies.
"Umngcipheko we-MDS usekwe kwisampulu yedatha evuzayo ukusuka kwizakhiwo ezincinci ukuya kwi-CPU kusetyenziswa isitishi esithelekelelwayo sokubulawa kwendawo," icacisa inkampani. “Ukusebenza ngokubonakalayo kwe-MDS kuntsonkothile kakhulu. Ubungozi ngokwabo abuboneleli umhlaseli ngendlela yokukhetha idatha afuna ukuyifumana. "
"I-MDS sele iqwalaselwe kwinqanaba le-hardware kwiiprosesa zethu ze-Intel Core zamva nje ze-8 kunye ne-9, kunye nesizukulwana se-XNUMX se-Intel Xeon Scalable processor usapho," yatsho inkampani. "Kwezinye iimveliso ezichaphazelekayo, amanyathelo okunciphisa ayafumaneka ngohlaziyo lwe-microcode ngokudibanisa nenkqubo efanelekileyo yokusebenza kunye nohlaziyo lwesoftware ye-hypervisor, ekhoyo ukuqala namhlanje. Sanikezela kwiwebhusayithi yethu kwaye siqhubeke nokukhuthaza wonke umntu ukuba agcine iinkqubo zabo zihlaziyiwe njengoko le yenye yeendlela ezilungileyo zokuhlala ukhuselekile. "
I-Intel iphinde yabonisa ukuba iqela lophando leZombieLoad belisebenza nenkampani kunye nabanye kwishishini lePC ukulungisa ubuthathaka ngaphambi kokuba baziwe esidlangalaleni. "Sithanda ukwenza umbulelo wethu kubaphandi abasebenze nathi kunye namaqabane ethu kwishishini ngegalelo labo kwisisombululo esilungelelanisiweyo kule ngxaki."
Ke kuthekani ngeHyper-Threading?
I-Intel ithe ukukhubaza i-Hyper-Threading ayifuni okanye ekuphela kwenketho yabasebenzisi bePC. Ngapha koko, i-Intel ithi ixhomekeke kumthengi ngamnye ukuba enze isigqibo sokuba enze ntoni. Ukuba awukwazi ukuqinisekisa ukhuseleko lwesoftware oyifakileyo, ke ewe, luluvo olulungileyo ukuvala i-Hyper-Threading. Ukuba isoftwe ivela kuphela kwivenkile yeMicrosoft, kwisebe lakho le-IT, okanye ifakwe ngokulula kwinto okholelwa ukuba iyimithombo ethembekileyo, unokushiya i-Hyper-Threading yenziwe yasebenza. Ngokwenene kuxhomekeke kwindlela ozixhalabele ngayo ngokhuseleko lwakho.
"Ngenxa yokuba izinto zahluka kakhulu phakathi kwabathengi, i-Intel ayicebisi ukukhubaza i-Hyper-Threading njengoko kubalulekile ukuqonda ukuba ayisiyiyo kuphela indlela yokubonelela ngokhuseleko kwi-MDS kwaye ayinikezeli ukhuseleko ngokwayo," yatsho inkampani kwingxelo. .
Ngelo xesha, ukusabela kwabenzi benkqubo yokusebenza kuyahluka omnye komnye.
UGoogle ukhuphe ukulungiswa kweChrome OS ekhubaza i-Hyper-Threading yeeChromebooks ngokuzenzekela. Abantu abafuna ukubuyisela itekhnoloji yokudibanisa imisonto emininzi bangayenza ngokwabo, inkampani ikholelwa.
I-Apple ikhuphe uhlaziyo lweMacOS Mojave kwaye yabhengeza ukuba abathengi benkampani, ngakumbi abo baqaphele ukhuseleko, banokukhubaza i-Hyper-Threading ngokwabo.
IMicrosoft ithe ikhuphe iipetshi zesoftware yayo ukunciphisa ukubakho kwe-MDS, kodwa ikwaphawule ukuba abathengi kufuneka bongeze bafumane uhlaziyo lwe-firmware kubavelisi bePC yabo.
Ngenxa yokuba, ubukhulu becala, abathengisi benkqubo yokusebenza baye bagqiba ekubeni bashiye i-Hyper-Threading inikwe amandla, isoyikiso seZombieLoad sibonakala singekho nzulu njengoko sasibonakala nje ngosuku oludlulileyo. Ukongeza, akukabikho meko eyaziwayo yokuba sesichengeni esisetyenziswa kuhlaselo lokwenyani.
Kwangaxeshanye, ukusebenzisa iipetshi ngaphandle kokukhubaza itekhnoloji ye-Hyper-Threading phantse ayinciphisi ukusebenza kwe-Intel processors.
Kodwa awuyi kukholelwa ukuba uyayijonga Impembelelo ye-Intel yeepetshi zokhuseleko ekusebenzeni xa i-Hyper-Threading ivaliwe. Inkampani ibanga ukuba iipatches zokhuseleko, kunye nokukhubaza i-Hyper-Threading, zinempembelelo encinci ngokukrokrelayo ekusebenzeni.
portal Andivumelani kakhulu noluvo lwe-Intel lokuba ukukhubaza i-Hyper-Threading ayongxaki enkulu, nangona i-Intel ibonisa kuxwebhu lwayo ukuba ukusebenza akutshintshi. Ingxaki kukuba iimvavanyo ze-Intel zezenziwe xa zikhubaza i-Hyper-Threading, kuba inkampani ayizange ivavanye imithwalo yemisebenzi enemisonto emininzi. Ukuba i-Intel ithathe i-Blender, iCinebench, okanye ezinye iibenchmarks ezenzelwe iiprosesa ezinemisonto emininzi kunye nemisonto emininzi, ngekhe sabona kwangoko ukusebenza okukhulu.
Ukugqamisa indlela iteknoloji ye-Hyper-Threading ebaluleke ngayo, unokujonga nje i-$ 9 ye-Intel i9900-500K kunye ne-$ 7 i9700-375K iprosesa, eyona nto ibalulekileyo yinkxaso yabo ye-Hyper-Threading. Ukukhubaza i-Hyper-Threading kwi-Intel processors yinto engakholelekiyo kuye nabani na okhathalayo malunga nokusebenza ngemisonto emininzi.
Kodwa kukho iindaba ezimnandi kwabo basebenzisa iiprosesa ze-Intel zamva nje. Inkampani yathi uninzi lwazo lwamva nje lwe-8th kunye ne-9th iprosesa yesizukulwana sele ine-hardware microcode fixes, ngoko akukho sizathu sokuba abanini be-i9-9900K bakhubaze i-Hyper-Threading. Ingozi yeZombieLoad ngokucacileyo iphezulu kwiiprosesa ezindala. Abanini bezi nkqubo baya kufuneka bathembele kwinkqubo yokusebenza kunye nohlaziyo lwesoftware, kunye nokusebenza kwezisombululo zabo ze-antivirus, ukunciphisa umngcipheko wokufumana ikhowudi engalunganga. Masiphinde sikhumbule inyani yokuba ukuza kuthi ga ngoku akukho hlaselo lisebenzisa iZombieLoad lwaziwayo.
