Linus Benedict Torvalds injiniya yesoftware, inozivikanwa nekutanga nekuchengetedza kuvandudzwa kweLinux kernel.
Pamusoro peLinux kernel developer mailing list, Linus Torvalds, akataura "kushungurudzika" kwake module kuita AMD fTPM.
Uye ndizvo izvozvo Kune mugadziri weLinux, AMD's fTPM module chimwe chinhu "mbeveve", sezvo ichiita senge ichiratidza kuti chinhu chakanakisa chekuita neiyi TPM mhinduro kungava kuidzima, zvirinani sekushandiswa kwayo kwehardware random number generation ine chekuita.
Linus Torvalds anotaura izvozvo fTPM dambudziko riri kukuvadza Linux kuita, kunze kwaizvozvo inoratidza izvozvo Murairo RDRAND inogona kushandiswa pachinzvimbo nokuda kwebasa rimwe chete.
fTPM ndiyo mhinduro chaiyo iyo inomhanya munzvimbo yakachengeteka pane processor. Chinangwa yeTPM iyi gadzirisa zvikanganiso zvinongowanikwa muprocessor software. Makambani mazhinji, akadai se AMD neIntel, anoshandisa fTPM kuchengetedza kwehardware yavo. Chaizvoizvo, TPMs, ingave firmware yakavakirwa kana Hardware yakavakirwa, inoshandiswa kugadzira zvakachengeteka uye kuchengetedza cryptographic kiyi, zvitupa, uye mapassword. Iwo ma modules anogadzirawo, pakati pezvimwe zvinhu, nhamba dzisina kujairika dzekushandisa nesoftware. Nekudaro, mune iyo AMD's fTPM, pane mamwe glitches.
Inotaurwa kuti kana uchishandisa AMD's fTPM, inowana flash yako yekuchengetedza kuburikidza neserial interface, uye mukuita kudaro, inononotsa basa reimwe hurongwa. Kana iyo module yaishandiswa kazhinji, semuenzaniso nesoftware yakagadzira hova dzenhamba dzisina kurongeka, mhedzisiro yevashandisi veakakanganisika masisitimu yaive kudonha kwekuita.
Zvinoenderana ne AMD, mamwe AMD Ryzen sisitimu masisitimu anogona kuita nguva nenguva fTPM-inoenderana yakawedzera ndangariro transaction paSPI flash memory (SPIROM) iri pabhodhi reamai. Izvo zvinogona kukonzeresa kumbomira kwechinguvana mukudyidzana kana kuterera system kusvika kutengeserana kwapera.
Dambudziko rakaonekwa paWindows PCs uye yakagadziriswa neBIOS update yakagadzirisa fTPM kuti ivandudze kushanda kwayo, kunyangwe dambudziko racho rakabatawo Linux, uye zvichiratidzika kuti kernel-level patch yakagadzirisa bug, kudzikira kwacho kwakabudazve, kukwevera hasha dzaLinus Torvalds.
"Ngatingodzima iyo yakapusa fTPM hwrnd," Torvalds akadaro neChina pane yakavhurika sosi yekuvandudza kernel rondedzero yetsamba.
Saka nekudaro, kutsamwa kwaLinus Torvalds kwanga kusiri "mhinduro" itwa, asi dambudziko richiri kubata avo vasina kuisa BIOS update inodiwa, pamwe nekugadzirisa hakuna kuverengera zvese buggy firmware iterations, kana iyo firmware yakanga isina kunyatsogadziriswa, saka kune vamwe vashandisi dambudziko rinoramba riripo.
Saka zano rekudzima fTPM nhamba jenareta, zvisinei neshanduro.
Sei chero munhu angashandisa iyi crap kana chero muchina waifungidzirwa kuti wakaigadzirisa, iyo sezviri pachena haina kushanda mushure mezvose, ingadai zvakare ine rdrand CPU yekuraira iyo isina dambudziko? Ini handioni chakaipa pakungotaura kuti chinhu chefTPM hachishande. Kunyangwe zvikazoshanda mune ramangwana, pane dzimwe nzira dzisina kushata," akanyora kudaro. Anobvuma kuti RdRand (iyo inodzorera nhamba dzisina kujairika kubva kune yakagadzirwa-in random number generator) inogona kunonoka, asi ichienzaniswa ne stutters inokonzerwa nefTPM, Torvalds inofunga kuti inogona kuva mhinduro yakanakisisa.
"Kutaura zvazviri, rdrand, uye rdseed kunyanya, inogona kunonoka. Asi ini ndinofunga tiri kutaura mazana eCPU cycles, pamwe zviuru zvishoma. Hapana chakafanana nemashura atakaona nefTPM, "akanyora kudaro. Chikonzero chaicho chebug hachisati chanyatsojeka, kunyangwe Torvalds akapa mashoma dzidziso pamusoro pezvingave zvichiitika. Mune imwezve chirevo chakareba pamusoro peiyo AMD's fTPM, Torvalds aiita sekukanda mumvuri pabhodhi reBIOS encoders asati aita kiyi yakakosha nezveCPU-based RDRAND versus fTPM-based HWRND.
Chekupedzisira, zvakakosha kuti titaure kuti AMD yakambokurudzira kushandisa TPM yemuviri seimwe nzira yeTPM firmware inoshandiswa nemabhobhobho akawanda, asi zvinotadza kufunga kuti bhodhi reamai rine musoro wakakodzera rinodiwawo kugamuchira module yakadaro, iyo. haina kuvimbiswa.
Kana uri kuda kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo Mune inotevera chinongedzo.
