Patching 2.6.9 for custom DSDT

Good morning all!

I'd like to try the custom Acer Aspire 1703 DSDT found on the acpi.sf.net site.

in drivers/acpi/osl.c I see the folloiwing

#ifdef CONFIG_ACPI_CUSTOM_DSDT
#include CONFIG_ACPI_CUSTOM_DSDT_FILE
#endif

Does this mean I can add the following to the top of the c file?

#define CONFIG_ACPI_CUSTOM_DSDT_FILE "/path/to/dsdt.file" #define CONFIG_ACPI_CUSTOM_DSDT

Or do I need the kernel patch mentioned on
http://acpi.sourceforge.net/wiki/index.php/HowToOverrideTable

In the later case I have a problem since I get the following error when applying the patch:

juliana:/usr/src/linux-2.6.9# patch -p1 -i ../osl.diff
patching file drivers/acpi/osl.c
patch: **** malformed patch at line 21: }

Thanks in advance for the replies :D

Patrick

Hello,

no, you should configure
make [config|menuconfig|xconfig]

your kernel to use a custom DSDT. The voice is

- Power management otions (ACPI, APM)
- ACPI ([...])
- Include Custom DSDT
- Custom DSDT Table file to include
/path/to/dsdt.file

NB, the DSDT should be in the AmlCode declaration.

Thx, bye,
Gismo / Luca

You can do that (thats what I do).

I think though that there should be a menu item in make config if this is already in the source.
