Ua ʻōlelo ʻo Apple ʻo ka hoʻoponopono piha ʻana i ka nāwaliwali ZombieLoad hou i nā kaʻina hana Intel hiki ke hōʻemi i ka hana a hiki i ka 40% i kekahi mau hihia. ʻOiaʻiʻo, e hilinaʻi nā mea āpau i ka kaʻina hana kūikawā a me ke ʻano i hoʻohana ʻia ai, akā i kēlā me kēia hihia he mea koʻikoʻi kēia i ka hana ʻana o ka ʻōnaehana.
I ka hoʻomaka ʻana, e hoʻomanaʻo mākou iā ʻoe i ka lā aʻe ua ʻike ʻia e pili ana i kahi nāwaliwali ʻē aʻe i ʻike ʻia ma nā kaʻina hana Intel. Kapa ʻia ʻo ia ʻo ZombieLoad, ʻoiai makemake ʻo Intel e hoʻohana i ka inoa ʻoi aku ka neutral Microarchitectural Data Sampling (MDS) a i ʻole Microarchitectural Data Sampling. Ua kamaʻilio mua mākou ma kahi kikoʻī e pili ana a loaʻa .
I kēia manawa ua hoʻopuka ʻo Apple i kāna ʻōlelo ponoʻī e pili ana i ka MDS, no ka mea, ua kūkulu ʻia kāna mau kamepiula Mac āpau ma nā chips Intel, a no laila hiki ke hoʻouka ʻia. Hāʻawi pū ka hui i kahi ala paʻakikī, akā maikaʻi, e like me ia, ke ala e pale ai i kāu kamepiula.
"Ua ʻike ʻo Intel i nā nāwaliwali i kapa ʻia ʻo microarchitectural data sampling (MDS) e pili ana i ka pākaukau a me nā kamepiula kamepiula me nā kaʻina hana Intel, me nā Mac hou āpau.
I ka manawa o kēia kākau ʻana, ʻaʻohe mea i ʻike ʻia e pili ana i kā mākou mea kūʻai. Eia nō naʻe, hiki i nā mea hoʻohana i manaʻoʻiʻo ua piʻi ka pilikia o ka hoʻouka ʻana i kā lākou kamepiula ke hoʻohana i ka palapala Terminal e hiki ai i kahi ʻōlelo aʻo CPU hou a hoʻopau i ka ʻenehana Hyper-Threading iā lākou iho, e hāʻawi i ka pale piha i kēia mau pilikia palekana.
Loaʻa kēia koho no macOS Mojave, High Sierra a me Sierra. Akā, hiki ke loa'a ka hopena nui i ka hana o kāu kamepiula.
Ua hōʻike ʻia ka hoʻāʻo ʻana e Apple ma Mei 2019 i kahi hāʻule o ka hana a hiki i 40%. Hoʻokomo ʻia ka hoʻāʻo ʻana i nā haʻahaʻa hana multi-threaded a me nā hōʻailona i loaʻa i ka lehulehu. Ua hana ʻia nā hoʻokolohua hana me nā kamepiula Mac koho. Hiki ke ʻokoʻa nā hopena maoli ma muli o ke kumu hoʻohālike, ka hoʻonohonoho ʻana, ke ʻano hoʻohana a me nā mea ʻē aʻe."
E hoʻomaopopo i ka hui ʻaʻole pono ka hoʻopau ʻana i ka Hyper-Threading. Pono ʻoe e hoʻohana i nā polokalamu i hōʻoia ʻia. ʻOiaʻiʻo, waiho ʻo Apple i ka mea hoʻohana i kahi koho: pale iā lākou iho a hōʻemi i ka hana, a waiho paha i nā mea āpau. Ua hoʻomaopopo pū ʻo Intel ua hoʻopili mua ʻo ia i nā ʻāpana lako e kūʻē iā MDS i kāna ʻewalu a me ka iwa o nā kaʻina hana, a me ka lua o ka hanauna Xeon-SP processors (Cascade Lake), no laila ʻaʻole hopohopo nā mea hoʻohana o kēia mau chips e pili ana i ka nāwaliwali hou. .
Akā ma ka laulā, ʻike ʻia e hōʻoia i ka pale piha ʻana iā ZombieLoad, pono ʻoe e hōʻano hou i ka hoʻonohonoho ʻōnaehana a hoʻohana i kahi kaʻina hana hou i loko, a i ʻole e hoʻopau i ka Hyper-Threading, a laila e hōʻemi nui i ka hana ʻōnaehana. ʻOiai ʻaʻole e pale ka mea hope i nā hoʻoweliweli ʻē aʻe e hoʻohana ana i ka hoʻokō kauoha speculative. Aia kekahi koho ʻē aʻe - e hoʻohana i kahi ʻōnaehana ma kahi kaʻina AMD. Akā i ka hihia o nā kamepiula Apple ʻaʻole hiki kēia.
