Samsung ayaa soo jeedisay ikhtiyaar darawal exFAT cusub oo loogu talagalay kernel Linux

Samsung soo jeediyay si loogu daro kernel Linux, xirmo dhejis ah oo leh hirgelinta darawal cusub oo exFAT ah, oo ku saleysan saldhigga koodhka "sdfat" ee hadda, oo loo sameeyay qalabka casriga ah ee Samsung Android. Haddii balastarrada la aqbalo, waxaa lagu dari doonaa Linux 5.6 kernel, kaas oo la filayo in la sii daayo 2-3 bilood gudahood. Marka la barbardhigo darawalka exFAT ee hore loogu daray kernel, darawalka cusub wuxuu bixiyaa waxqabad koror ku dhawaad ​​10%.

Farqiga ugu weyn ee u dhexeeya daabacaadda darawalka sdfat ee kernel Linux ugu weyn iyo darawalka ay Samsung u isticmaasho Android:

• Koodhka leh hirgelinta nidaamka faylka VFAT ayaa meesha laga saaray, maadaama nidaamka faylkan mar horeba si gaar ah loogu taageeray kernel (fs / dufan);
• Darawalka waxaa laga bedelay sdfat loona bedelay exfat;
• Codka dib ayaa loo habeeyey. Qoraallada isha waxaa lagu hagaajiyay shuruudaha qaabaynta koodhka ee kernel Linux;
• Hawlgallada xogta badan ayaa la hagaajiyay, sida abuurista faylal, raadinta walxaha nidaamka faylka (lookup) iyo go'aaminta waxa ku jira hagaha (readdir).
• Khaladaadka la aqoonsaday intii lagu jiray baaritaan dheeraad ah waa la saxay.

Aan ku xasuusino taas kadib Microsoft la daabacay Tilmaamaha guud iyo isticmaalka bilaashka ah royalty ee shatiyada exFAT ee Linux, darawal exFAT, sidoo kale ay samaysay Samsung laakiin ku salaysan code dhaxalgal ah (nooca 1.2.9). Dadka xiiseeya firmware-ka Android ayaa ahaa xamaali darawal sdFAT (2.x) cusub, laakiin Samsung waxay si madaxbanaan u go'aansatey inay kor u qaaddo darawalkan kernel-ka Linux ugu weyn. Intaa waxaa dheer, Paragon Software furay darawal kale, oo hore loogu keenay qayb gaar ah oo darawaliin ah.

Nidaamka faylka exFAT waxaa abuuray Microsoft si ay uga gudubto xaddidaadda FAT32 marka loo isticmaalo Flash Drive-yada awoodda badan. Taageerada nidaamka faylka exFAT ayaa ka soo muuqday Xirmooyinka Adeegga Windows Vista 1 iyo Windows XP oo leh Adeegga Adeegga 2. Cabbirka faylka ugu badan marka loo eego FAT32 ayaa laga ballaariyay 4 GB ilaa 16 exabyte, iyo xaddidaadda cabbirka ugu sarreeya ee 32 GB waa la tirtiray. , si loo yareeyo kala qaybsanaanta iyo kordhinta xawaaraha, waxaa la soo bandhigay khariidad yar oo ah blocks lacag la'aan ah, xadka tirada faylasha ee hal buug ayaa la gaarsiiyay 65 kun, iyo awoodda lagu kaydiyo ACLs ayaa la bixiyay.
