Just for info, I had started answering the comments from Tho= mas and Carlos. Here is my proposed version as description for Kconfig: With this feature you will be able to provide a customized DSDT by adding it to your initramfs. Overriding of the DSDT is mainly though= t for developing/testing purposes! If you have problems with ACPI on your machine and you have fixed it up by modifying the DSDT, do not override the DSDT as a long term solution. E.g. if you add new memory to your machine, the modified DSDT will not work (BIOS would generate a slightly adjusted one). Always report bugs in a DSDT to your computer vendor and to bugzilla.kernel.org (assigned to the ACP= I component). In case your mkinitrd tool does not support this feature, a script i= s provided in the documentation. For more details on this option see . =20 If you feel like tinkering with the DSDT or might have to test a corrected DSDT one day select this option. It is safe to say Y here. You can use it as inspiration ;-) More over, I was thinking of adding a= note in dsdt-initrd.txt like this: Do note that the format of the table included in the initramfs is binary (iasl -ta),= while if you include the DSDT straight inside the kernel, the format is hexad= ecimal (iasl -tc).
