| Len Brown | d89e9d6 | 2008-02-06 19:28:02 -0500 | [diff] [blame] | 1 | Linux supports two methods of overriding the BIOS DSDT: |
| 2 | |
| 3 | CONFIG_ACPI_CUSTOM_DSDT builds the image into the kernel. |
| 4 | |
| 5 | CONFIG_ACPI_CUSTOM_DSDT_INITRD adds the image to the initrd. |
| 6 | |
| 7 | When to use these methods is described in detail on the |
| 8 | Linux/ACPI home page: |
| 9 | http://www.lesswatts.org/projects/acpi/overridingDSDT.php |
| 10 | |
| 11 | Note that if both options are used, the DSDT supplied |
| 12 | by the INITRD method takes precedence. |
| 13 | |
| 14 | Documentation/initramfs-add-dsdt.sh is provided for convenience |
| 15 | for use with the CONFIG_ACPI_CUSTOM_DSDT_INITRD method. |
