Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2832
NOTE: Truncated patchset due to missing public @redhat.com email
address on your GitLab profile at https://gitlab.com/-/profile.
Once that is fixed, close and reopen the merge request to
retrigger sending the emails.
Some of the drivers are not used for x86 systems but they are enabled and
shipped with Fedora kernel release. These unnecessary kernel modules increase
the package size for x86 platform. If we manually disable all unnecessary
drivers, it takes time and is difficult to address the errors. If a place can
be used to manage a list of necessary drivers and based on the list, the
unnecessary drivers can be automatically disabled, it certainly reduces a part
of the workload for the maintainer. Moreover, the package size can also be
reduced by the results of the tool. In this work, we proposed an automation
script tool that can be used to disable the drivers based on a configuration
list. The drivers that are not in the list will be disabled and reduce the
kernel module package size.
This script filters and disables the unused driver through an allow list
file in JSON format. The maintainer sets a list kernel config to the
allow list file and then runs this script. It will compare the current
setting with allow list. If the current settings aren't listed in the
allow list, the script will generate a redhat kernel config file and
disable it.
Moreover, the allow list file includes the setting of the commit title and
commit message. The maintainer can make that information according to the
requirement. The format is shown below.
{
"name":"iio_accel",
"driver_path":"drivers/iio/accel/",
"redhat_config_path":"redhat/configs/fedora/generic",
"redhat_x86_config_path":"redhat/configs/fedora/generic/x86",
"allow_list":[
"CONFIG_BMC150_ACCEL_I2C",
"CONFIG_DA280",
"CONFIG_HID_SENSOR_ACCEL_3D",
"CONFIG_KXCJK1013",
"CONFIG_MMA7660",
"CONFIG_MMA8452",
"CONFIG_MXC4005",
"CONFIG_MXC6255",
"CONFIG_IIO_ST_ACCEL_I2C_3AXIS",
"CONFIG_IIO_ST_ACCEL_3AXIS",
"CONFIG_IIO_CROS_EC_ACCEL_LEGACY",
"CONFIG_BMC150_ACCEL"
],
"commit_title":"Disable accel drivers for Fedora x86",
"commit_msg":"Disable the following accel drivers because they are not used
on any x86 boards.\n{{ config_list }}"
}
The second commit includes the result of the script. It disabled the unused
iio accel drivers for x86 since they were not used in any x86 boards.
