i-exFAT uhlelo lwefayela olwenziwe yi-Microsoft ukubhekana nemikhawulo ye-FAT32 lapho isetshenziswa kuma-flash drive amakhulu. Ukusekelwa kohlelo lwefayela le-exFAT ivele kwiWindows Vista Service Pack 1 nakuWindows XP ngeService Pack 2.
Usayizi wefayela ophakeme uma kuqhathaniswa ne-FAT32 enwetshiwe ukusuka ku-4GB kuye kuma-exabyte ayi-16, umkhawulo osayizi omkhulu wokuhlukanisa ongu-32GB ususiwe ukunciphisa ukwahlukaniswa, kanye ne-bitmap yama-block yamahhala yethulwe ngejubane, umkhawulo wenani lamafayela kuhla lwemibhalo wakhushulwa waba yizinkulungwane ezingama-65, ikhono lokugcina ama-ACL lanikezwa.
Njengokwazi kwakho, Kuze kube muva nje ukusetshenziswa kwalolu hlelo lwefayela ku-Linux bekudlulile ukwenziwa kokusekelwa kwayo ngosizo lwe ukusetshenziswa kwesoftware eyenziwe ngabantu besithathu. Ngoba ukuqaliswa bekuyimfihlo.
Kodwa kuze kube ezinyangeni ezimbalwa ezedlule iMicrosoft ishicilele imininingwane etholakala esidlangalaleni futhi yenza kwaba nokwenzeka ukusebenzisa amalungelo obunikazi we-exFAT we-Linux mahhala.
Noma kunjalo lesi sinyathelo seMicrosoft asikhiphanga ikhodi yomthombo, okwenzayo ukhipha kuphela amalungelo wokusebenzisa we-exFAT kanye nokubeka noma iyiphi inhloso yokufuna noma yokufuna kanye namalungu e-Open Invention Network (OIN).
Kukude nalokho, umshayeli we-exFAT uphinde wakhiqizwa yi-Samsung futhi okuphakamise ukufaka ku-Linux kernel isethi yamachashazi ngokuqaliswa komshayeli omusha we-exFAT, ngokususelwa kukhodi eyisisekelo "sdfat" zamanje, zenzelwe i-firmware ye-Samsung Android smartphones.
Sihlela ukuphatha lokhu kukhishwa njengekusasa eliphansi le-codebase uma selihlanganisiwe, futhi zonke izici ezintsha nokulungiswa kwamaphutha kuzoqala kuqala.
Ukwahlulela ngemininingwane etholakalayo, ikhodi entsha ifaka ukusebenza okuningi ngemethadatha futhi kufaka phakathi ukulungiswa kwamaphutha amaningi. Kuze kube manje, isetshenziswa kuphela kumadivayisi we-Samsung Android.
Kulokhu kusebenza okuhlinzekwa yi-Samsung, kungezwe esigabeni sokuhlola »isiteji» ("Abashayeli / isiteji /") I-Linux kernel 5.4 ngokususelwa kukhodi ephelelwe yisikhathi (inguqulo 1.2.9).
Noma abathandi be-firmware be-Android befaka umshayeli omusha sdFAT (2.x), kepha AbakwaSamsung banqume ukwethula lo mshayeli ku-kernel eyinhloko ye-Linux uqobo.
Kuze kube manje ukuqaliswa okuhlongozwayo kwe-Samsung kuthole ukugunyazwa okuningana kusuka kubakhiqizi be-Linux kernel abavelele.
Njengalokhu, unikezwe umzuzu, asekhona amathuba okuthi lo mshayeli we-exFAT angahle athathe isikhundla somshayeli wamanje we-prep exFAT weLinux 5.6 uma ukubuyekezwa kwekhodi okusele kuhamba kahle.
Uma kuqhathaniswa nomshayeli we-sdfat othunyelwe emafoninis, kwenziwe izinguquko ezilandelayo:
- Uma kuqhathaniswa nomshayeli we-exFAT owake wanezelwa ku-kernel phambilini, umshayeli omusha uhlinzeka ngokunyuka kokusebenza okucishe kube ngu-10%.
- Ikhodi enokusetshenziswa kwe-VFAT FS isusiwe, njengoba lolu hlelo lwefayela seluvele lusekelwa ngokuhlukile ku-kernel (fs / fat).
- Igama lesilawuli lishintshelwe ku-exfat
- Ikhodi iphindwe yangeniswa futhi yahlanzwa ukuze ihlanganiswe ngokuphelele nohlobo oluphezulu lweLinux bese ilandela isitayela sokubhala ngeLinux
- Ukwenziwa kokusebenza kwemethadatha, njengokwakhiwa kwefayela, ukuseshwa kwento yefayela (ukusesha), kanye nencazelo yokuqukethwe kwesiqondisi (i-readdir) yenziwe.
- Kulungiswe iziphazamisi ngesikhathi sokuhlolwa okwengeziwe.
Uma ama-patches amukelwa, azofakwa kukhodi ye-Linux 5.6 kernel, okushicilelwa kwakhe kulindeleke ezinyangeni ezi-2 noma ezi-3 kuze kube manje. Noma kungavela inkinga, ukuqaliswa komshayeli we-Samsung exFAT kungabambezeleka kunguqulo 5.7 ye-Linux kernel.
Ekugcineni, uma ufuna ukwazi kabanzi ngezindaba, kanye nezici ezingezwe enguqulweni entsha yesishayeli se-Samung exFAT engu-11 ongayenza ku isixhumanisi esilandelayo.
