Opensource exfat-linux driver provide better performance Comparing with the existing Moto exfat-nofuse It could support various kernel versions l(CR) 5.4/4.19/4.14/4.9 Original source :https://github.com/arter97/exfat-linux.git version 5.8-2arter97 This commit also integrates almost all the exfat upstream changes from kernel 5.8-5.16 listed in: https://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/exfat.git/log/fs/exfat?h=exfat-for-5.16-rc1 Change-Id: I7c0db070ee33be8f7f24a42f987b4e825d957998 Signed-off-by: a17671 <a17671@motorola.com> Reviewed-on: https://gerrit.mot.com/2137224 SLTApproved: Slta Waiver SME-Granted: SME Approvals Granted Tested-by: Jira Key Reviewed-by: Xinmin Fu <fuxm1@motorola.com> Reviewed-by: Chuanchun Zhu <zhucc2@motorola.com> Reviewed-by: Xiaojun Ji <jixj@motorola.com> Reviewed-by: Xiangpo Zhao <zhaoxp3@motorola.com> Submit-Approved: Jira Key
exfat-nofuse
Linux non-fuse read/write kernel driver for the exFAT, FAT12, FAT16 and vfat (FAT32) file systems.
Originally ported from Android kernel v3.0.
Kudos to ksv1986 for the mutex patch!
Thanks to JackNorris for being awesome and providing the clear_inode() patch.
Big thanks to lqs for completing the driver!
Big thanks to benpicco for fixing 3.11.y compatibility!
Special thanks to github user AndreiLux for spreading the word about the leak!
Installing as a stand-alone module:
make
sudo make install
To load the driver manually, run this as root:
modprobe exfat
You may also specify custom toolchains by using CROSS_COMPILE flag, in my case:
CROSS_COMPILE=../dorimanx-SG2-I9100-Kernel/android-toolchain/bin/arm-eabi-
Installing as a part of the kernel:
Let's take [linux] as the path to your kernel source dir...
cd [linux]
cp -rvf exfat-nofuse [linux]/fs/exfat
edit [linux]/fs/Kconfig
menu "DOS/FAT/NT Filesystems"
source "fs/fat/Kconfig"
+source "fs/exfat/Kconfig"
source "fs/ntfs/Kconfig"
endmenu
edit [linux]/fs/Makefile
obj-$(CONFIG_FAT_FS) += fat/
+obj-$(CONFIG_EXFAT_FS) += exfat/
obj-$(CONFIG_BFS_FS) += bfs/
cd [linux]
make menuconfig
Go to:
File systems > DOS/FAT/NT check exfat as MODULE (M) (437) Default codepage for exFAT (utf8) Default iocharset for exFAT
ESC to main menu Save an Alternate Configuration File ESC ESC
build your kernel
Have fun.
Installing as a DKMS module:
You can have even more fun with exfat-nofuse by installing it as a DKMS module has the main advantage of being auto-compiled (and thus, possibly surviving) between kernel upgrades.
First, get dkms. On Ubuntu this should be:
sudo apt install dkms
Then copy the root of this repository to /usr/share:
sudo cp -R . /usr/src/exfat-1.2.8 (or whatever version number declared on dkms.conf is)
sudo dkms add -m exfat -v 1.2.8
Build and load the module:
sudo dkms build -m exfat -v 1.2.8
sudo dkms install -m exfat -v 1.2.8
Now you have a proper dkms module that will work for a long time... hopefully.
