Nooc cusub oo darawalka exFAT ah ayaa loo soo jeediyay kernel Linux

Horumarinta Kuuriya Park Ju Hyung, oo ku takhasusay u soo dejinta Android firmware qalabyo kala duwan, soo bandhigay daabacaadda cusub ee darawalka ee nidaamka faylka exFAT - exfat-linux, kaas oo ah fargeeto ka yimid darawalka "sdFAT", horumaray by Samsung. Hadda, laanta diyaarinta ee kernel Linux waa horeba ku daray Dareewalka exFAT ee Samsung, laakiin waxay ku saleysan tahay codebase laan darawalnimo hore (1.2.9). Waqtigan xaadirka ah, Samsung waxay isticmaashaa nooc gabi ahaanba ka duwan darawalka "sdFAT" (2.2.0) ee darawalkeeda casriga ah, oo laan ka mid ah horumarinta Park Ju Hyung.

Marka lagu daro u gudubka saldhigga koodhka hadda, darawalka exfat-linux ee la soo jeediyay waxaa lagu kala saarayaa ka saarida wax ka beddelka Samsung-gaar ah, sida joogitaanka koodka la shaqeynta FAT12/16/32 (xogta FS waxaa lagu taageeraa Linux darawallo kala duwan) iyo qalab-dhismay. Ka saarista qaybahan waxay suurtogalisay in darawalka laga dhigo mid la qaadi karo oo la waafajiyo kernel-ka caadiga ah ee Linux, oo aan ahayn kaliya kernels loo isticmaalo Samsung Android firmware.

Horumariyuhu waxa kale oo uu qabtay shaqo si loo fududeeyo rakibaadda darawalka. Isticmaalayaasha Ubuntu way ka rakiban karaan Kaydka PPA, iyo qaybinta kale, kaliya soo deji koodka oo orod "make && make install". Darawalka sidoo kale waxaa lagu soo wada ururin karaa kernel Linux, tusaale ahaan marka la diyaarinayo firmware-ka Android.

Mustaqbalka, waxaa la qorsheeyay in la sii wado darawalka ilaa taariikhda iyada oo isbeddelada laga beddelayo saldhigga koodhka Samsung ee ugu weyn oo loo sii daayo kernel cusub. Hadda, darawalka waa la tijaabiyay markii lagu dhisay kernels min 3.4 ilaa 5.3-rc ee x86 (i386), x86_64 (amd64), ARM32 (AArch32) iyo ARM64 (AArch64). Qoraaga kala duwanaanshaha darawalka cusub waxa uu soo jeediyay soosaarayaasha kernel-ka in ay tixgeliyaan in lagu daro darawalka cusub ee laanta diyaarinta iyada oo saldhig u ah darawalka kernel-ka exFAT, halkii ay ka ahaan lahaayeen nooc cusub oo dhawaan lagu daray.

Tijaabooyinka waxqabadku waxay muujiyeen korodhka xawaaraha qorista marka la isticmaalayo darawalka cusub. Marka la dhigayo qaybta ramdisk: 2173 MB/s oo ka soo horjeeda 1961 MB/s ee taxanaha I/O, 2222 MB/s oo ka soo horjeeda 2160 MB/s si aad u geliso random, iyo marka qaybta NVMe la gelinayo: 1832 MB/s oo ka soo horjeeda 1678 MB /s iyo 1885 MB/s iyo 1827 MB/s. Xawaaraha wax-akhrinta ayaa kordhay imtixaankii akhriska ee xidhiidhsanaa ee ramdisk (7042 MB/s oo ka soo horjeeda 6849 MB/s) iyo akhriska random ee NVMe (26 MB/s iyo 24 MB/s)
