Enabling ExaGear Transcoding

Each time the server is restarted, perform 6 and 7 in this section to manually register transcoding rules.

Mount the binfmt_misc file system.
It is mounted by default. If not, manually mount it.
1
mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
Create an /opt/exagear directory for storing the ubt_a32a64 file.
1 2
mkdir -p /opt/exagear chmod -R 700 /opt/exagear
Upload the ExaGear transcoding package Exagear-ARM32-ARM64.tar.gz to ~/dependency. Configure appropriate permissions on the uploaded files and directories. It is not recommended to configure the write permission for other users in the owner group and other owner groups.

Decompress the patch package and adjust the permissions.

cd ~/dependency/
tar -xzvf Exagear-ARM32-ARM64.tar.gz
chown -R root:root output

Copy the ubt_a32a64 file to the /opt/exagear directory.

1	cp ~/dependency/output/ubt_a32a64 /opt/exagear/

Mount and register the ExaGear transcoding rules.

echo ":ubt_a32a64:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff:/opt/exagear/ubt_a32a64:POCF" > /proc/sys/fs/binfmt_misc/register

Check whether the ExaGear rules are successfully registered and ensure that the directories for storing the ubt_a32a64 file are consistent with /opt/exagear/ubt_a32a64.
1
cat /proc/sys/fs/binfmt_misc/ubt_a32a64
If the following information is displayed, the registration is successful:
