Korea\u0144ski deweloper Park Ju Hyung, specjalizuj\u0105cy si\u0119 w portowaniu firmware'u Android na r\u00f3\u017cne urz\u0105dzenia, przedstawi\u0142<\/a><\/noindex> nowa wersja sterownika dla systemu plik\u00f3w exFAT — exfat-linux<\/a><\/noindex>, kt\u00f3ry jest odga\u0142\u0119zieniem sterownika «sdFAT», opracowanego<\/a><\/noindex> firmy Samsung. Obecnie do ga\u0142\u0119zi staging j\u0105dra Linux ju\u017c dodano<\/a><\/noindex> sterownik exFAT od Samsunga, ale oparty jest na starszej bazie kodu starej ga\u0142\u0119zi sterownika<\/a><\/noindex> (1.2.9). Obecnie Samsung stosuje w swoich smartfonach ca\u0142kowicie inn\u0105 wersj\u0119 sterownika «sdFAT» (2.2.0), z kt\u00f3rego wywodzi si\u0119 opracowanie Park Ju Hyung.<\/p>\n

Opr\u00f3cz przej\u015bcia na aktualn\u0105 baz\u0119 kodu, proponowany sterownik exfat-linux r\u00f3\u017cni si\u0119 usuni\u0119ciem specyficznych dla Samsunga modyfikacji, takich jak kod do obs\u0142ugi FAT12\/16\/32 (te systemy plik\u00f3w s\u0105 obs\u0142ugiwane w Linuxie przez oddzielne sterowniki) oraz wbudowany defragmentator. Usuni\u0119cie tych komponent\u00f3w pozwoli\u0142o uczyni\u0107 sterownik przeno\u015bnym i dostosowa\u0107 go do standardowego j\u0105dra Linux, a nie tylko do j\u0105der stosowanych w firmware'ach Androida Samsunga. <\/p>\n

Deweloper dokona\u0142 r\u00f3wnie\u017c uproszczenia instalacji sterownika. U\u017cytkownicy Ubuntu mog\u0105 zainstalowa\u0107 go z repozytorium PPA<\/a><\/noindex>, a dla pozosta\u0142ych dystrybucji wystarczy pobra\u0107 kod i wykona\u0107 «make && make install». Sterownik mo\u017ce by\u0107 tak\u017ce kompilowany razem z j\u0105drem Linux, na przyk\u0142ad przy przygotowywaniu firmware dla Androida.<\/p>\n

W przysz\u0142o\u015bci planowane jest utrzymywanie sterownika w aktualnym stanie, przenosz\u0105c zmiany z g\u0142\u00f3wnej bazy kodu Samsunga i portuj\u0105c go do nowych wyda\u0144 j\u0105dra. Obecnie praca sterownika zosta\u0142a zweryfikowana podczas budowy z j\u0105drami od 3.4 do 5.3-rc na platformach x86 (i386), x86_64 (amd64), ARM32 (AArch32) i ARM64 (AArch64). Autor nowej wersji sterownika zaproponowa\u0142 deweloperom j\u0105dra rozwa\u017cenie w\u0142\u0105czenia nowego sterownika do ga\u0142\u0119zi staging jako podstawy dla standardowego sterownika exFAT j\u0105dra, zamiast niedawno dodanej przestarza\u0142ej wersji.<\/p>\n

Przeprowadzone testy wydajno\u015bci wykaza\u0142y wzrost pr\u0119dko\u015bci operacji zapisu przy u\u017cyciu nowego sterownika. Przy umieszczaniu partycji w ramdisk: 2173 MB\/s w por\u00f3wnaniu do 1961 MB\/s przy sekwencyjnym wej\u015bciu\/wyj\u015bciu, 2222 MB\/s w por\u00f3wnaniu do 2160 MB\/s przy dost\u0119pie losowym, a przy umieszczaniu partycji w NVMe: 1832 MB\/s w por\u00f3wnaniu do 1678 MB\/s i 1885 MB\/s w por\u00f3wnaniu do 1827 MB\/s. Przyspieszenie operacji odczytu wzros\u0142o w te\u015bcie sekwencyjnego odczytu w ramdisk (7042 MB\/s w por\u00f3wnaniu do 6849 MB\/s) oraz odczytu losowego w NVMe (26 MB\/s w por\u00f3wnaniu do 24 MB\/s)
