Subject: [PATCH] dracut: Implement ACPI table overriding
|
|
|
712866 |
|
|
|
712866 |
An example config file for this feature could be:
|
|
|
712866 |
|
|
|
712866 |
/etc/dracut.conf.d/03-acpi-override.conf
|
|
|
712866 |
|
|
|
712866 |
with this content:
|
|
|
712866 |
acpi_override="yes"
|
|
|
712866 |
acpi_table_dir="/etc/dracut.conf.d/acpi_tables"
|
|
|
712866 |
|
|
|
712866 |
Then all files ending with *.aml will be put into the early cpio
|
|
|
712866 |
(kernel/firmware/acpi) and will be used to replace the BIOS provided tables
|
|
|
712866 |
if the kernel supports this feature.
