El desarrollador coreano Park Ju Hyung, especializado en la portaci\u00f3n de firmware Android para diversos dispositivos, present\u00f3<\/a><\/noindex> nueva versi\u00f3n del controlador para el sistema de archivos exFAT \u2014 exfat-linux<\/a><\/noindex>, que es una ramificaci\u00f3n del controlador \u00absdFAT\u00bb, desarrollado<\/a><\/noindex> de la compa\u00f1\u00eda Samsung. Actualmente, ya en la rama staging del n\u00facleo de Linux, se ha agregado<\/a><\/noindex> el controlador exFAT de Samsung, pero se basa en una antigua base de c\u00f3digo de la versi\u00f3n del controlador<\/a><\/noindex> (1.2.9). Actualmente, Samsung utiliza en sus smartphones una versi\u00f3n completamente diferente del controlador \u00absdFAT\u00bb (2.2.0), de la cual se desarroll\u00f3 la variante Park Ju Hyung.<\/p>\n

Adem\u00e1s de la actualizaci\u00f3n a la base de c\u00f3digo actual, el controlador propuesto exfat-linux se diferencia por la eliminaci\u00f3n de modificaciones espec\u00edficas de Samsung, como la presencia de c\u00f3digo para trabajar con FAT12\/16\/32 (los datos del sistema de archivos son compatibles en Linux con controladores separados) y un desfragmentador integrado. La eliminaci\u00f3n de estos componentes ha permitido hacer el controlador portable y adaptarlo para el n\u00facleo est\u00e1ndar de Linux, no solo para los n\u00facleos utilizados en los firmwares de Android de Samsung. <\/p>\n

El desarrollador tambi\u00e9n ha trabajado para simplificar la instalaci\u00f3n del controlador. Los usuarios de Ubuntu pueden instalarlo desde el repositorio PPA<\/a><\/noindex>, y para otras distribuciones, basta con descargar el c\u00f3digo y ejecutar \u00abmake && make install\u00bb. El controlador tambi\u00e9n puede ser compilado junto con el n\u00facleo de Linux, por ejemplo, al preparar firmware para Android.<\/p>\n

En el futuro, se planea mantener el controlador actualizado, trasladando cambios desde la base de c\u00f3digo principal de Samsung y port\u00e1ndolo para nuevos lanzamientos del n\u00facleo. Actualmente, la funcionalidad del controlador ha sido validada al compilarse con n\u00facleos desde 3.4 hasta 5.3-rc en plataformas x86 (i386), x86_64 (amd64), ARM32 (AArch32) y ARM64 (AArch64). El autor de la nueva versi\u00f3n del controlador propuso a los desarrolladores del n\u00facleo considerar la inclusi\u00f3n del nuevo controlador en la rama staging como base para el controlador exFAT est\u00e1ndar del n\u00facleo, en lugar de la variante obsoleta recientemente a\u00f1adida.<\/p>\n

Las pruebas de rendimiento realizadas mostraron un aumento en la velocidad de las operaciones de escritura al usar el nuevo controlador. Al colocar la partici\u00f3n en ramdisk: 2173 MB\/s en comparaci\u00f3n con 1961 MB\/s en I\/O secuencial, 2222 MB\/s en comparaci\u00f3n con 2160 MB\/s en acceso aleatorio, y al colocar la partici\u00f3n en NVMe: 1832 MB\/s en comparaci\u00f3n con 1678 MB\/s y 1885 MB\/s en comparaci\u00f3n con 1827 MB\/s. La velocidad de las operaciones de lectura aument\u00f3 en la prueba de lectura secuencial en ramdisk (7042 MB\/s en comparaci\u00f3n con 6849 MB\/s) y en la lectura aleatoria en NVMe (26 MB\/s en comparaci\u00f3n con 24 MB\/s).
