Dezvoltatorul coreean Park Ju Hyung, specializat \u00een portarea firmware-urilor Android pentru diverse dispozitive, a prezentat<\/a><\/noindex> o versiune nou\u0103 a driverului pentru sistemul de fi\u0219iere exFAT - exfat-linux<\/a><\/noindex>, care este o ramificare a driverului \u201esdFAT\u201d, dezvoltat de<\/a><\/noindex> compania Samsung. \u00cen prezent, ramura de staging a nucleului Linux con\u021bine deja ad\u0103ugat<\/a><\/noindex> driverul exFAT de la Samsung, dar este bazat pe o baz\u0103 de cod veche a vechiului driver<\/a><\/noindex> (1.2.9). \u00cen prezent, Samsung utilizeaz\u0103 \u00een smartphone-urile sale o variant\u0103 complet diferit\u0103 a driverului \u201esdFAT\u201d (2.2.0), ramifica\u021bia din care a fost dezvoltat Park Ju Hyung.<\/p>\n

\u00cen plus fa\u021b\u0103 de trecerea la o baz\u0103 de cod actualizat\u0103, noul driver exfat-linux se distinge prin eliminarea modific\u0103rilor specifice Samsung, cum ar fi prezen\u021ba codului pentru lucrul cu FAT12\/16\/32 (aceste sisteme de fi\u0219iere sunt suportate \u00een Linux de c\u0103tre drivere separate) \u0219i a unui defragmentator \u00eencorporat. Eliminarea acestor componente a permis ca driverul s\u0103 fie portabil \u0219i s\u0103 fie adaptat pentru nucleul standard Linux, \u0219i nu doar pentru nucleele utilizate \u00een firmware-urile Android de la Samsung. <\/p>\n

Dezvoltatorul a realizat, de asemenea, lucr\u0103ri pentru simplificarea instal\u0103rii driverului. Utilizatorii Ubuntu pot s\u0103-l instaleze din depozitul PPA<\/a><\/noindex>, iar pentru celelalte distribu\u021bii este suficient s\u0103 desc\u0103rca\u021bi codul \u0219i s\u0103 executa\u021bi \u201emake && make install\u201d. Driverul poate fi, de asemenea, compilat \u00eempreun\u0103 cu nucleul Linux, de exemplu, la preg\u0103tirea firmware-urilor pentru Android.<\/p>\n

\u00cen viitor, se inten\u021bioneaz\u0103 men\u021binerea driverului actualizat, prin transferul modific\u0103rilor din baza principal\u0103 de cod Samsung \u0219i portarea acestuia pentru noile versiuni ale nucleului. \u00cen prezent, func\u021bionarea driverului a fost verificat\u0103 la compilarea cu nucleele \u00eencep\u00e2nd de la 3.4 \u0219i termin\u00e2nd cu 5.3-rc pe platformele x86 (i386), x86_64 (amd64), ARM32 (AArch32) \u0219i ARM64 (AArch64). Autorul noii variante a driverului a propus dezvoltatorilor nucleului s\u0103 ia \u00een considerare includerea noului driver \u00een ramura de staging ca baz\u0103 pentru driverul standard exFAT al nucleului, \u00een locul variantei de tip vechi recent ad\u0103ugate.<\/p>\n

Teste de performan\u021b\u0103 efectuate au ar\u0103tat o cre\u0219tere a vitezei opera\u021biunilor de scriere utiliz\u00e2nd noul driver. C\u00e2nd sec\u021biunea este plasat\u0103 \u00een ramdisk: 2173 MB\/s comparativ cu 1961 MB\/s la citire\/scriere secven\u021bial\u0103, 2222 MB\/s comparativ cu 2160 MB\/s la acces aleator, iar c\u00e2nd sec\u021biunea este plasat\u0103 \u00een NVMe: 1832 MB\/s comparativ cu 1678 MB\/s \u0219i 1885 MB\/s comparativ cu 1827 MB\/s. Viteza opera\u021biunilor de citire a crescut \u00een testul de citire secven\u021bial\u0103 \u00een ramdisk (7042 MB\/s comparativ cu 6849 MB\/s) \u0219i citire aleatorie \u00een NVMe (26 MB\/s comparativ cu 24 MB\/s)
