dsdt with 2.5

dsdt with 2.5

[roychris]

I've just fixed my dsdt. How can I load it with the 2.5.69 kernel ?

Thanks

Try
http://www.behnel.de/acpi/acpi-custom-DSDT.patch
resp.
http://www.behnel.de/acpi/samsung-acpi.html

At least, it works for 2.4, but I don't see why it shouldn't work for ACPI in 2.5.

BTW: There were patches recently that allow loading the DSDT from an initrd. Search the archives for that.

Exact same procedure as for the 2.4 kernel (I don't know, though
for the initrd patch..).

This function is called for several tables, you must check if the DSDT
table is going to be replaced.
I have ported my DSDT in initrd to 2.5.69 and will release it within the
next one or two hours.

Re: custom dsdt with 2.5

[roychris]

I changed by hand the osl.c of the kernel 2.5. I can send you a diff if 
you want. This is the few lines I changed :

#include "/my/home/dsdt.hex"

and

*new_table = (struct acpi_table_header *) AmlCode;

Now I have this error at boot time :

ACPI: Subsystem revision 20030418
    ACPI-0291: *** Info: Table [DSDT] replaced by host OS
    ACPI-0227: *** Error: Invalid signature where RSDP indicates 
RSDT/XSDT should be located
    ACPI-0103: *** Error: acpi_load_tables: Could not load RSDT: 
AE_BAD_SIGNATURE
    ACPI-0133: *** Error: acpi_load_tables: Could not load tables: 
AE_BAD_SIGNATURE
ACPI: Unable to load the System Description Tables


Could you help me ?

*ALL* acpi tables will be passed to acpi_table_override().  Therefore,
the RSDT table have been replaced by the table that you have provided.
Since that is not what you want (RSDT is not DSDT), the ACPI subsystem
can not work properly.

Do something like this:

	*new_table = NULL;

	if (!strncmp((strncmp(existing_table->signature, DSDT_SIG, 4))))
		*new_table = (struct acpi_table_header *) AmlCode;


BTW, I don't see any reason why you have to patch by hand osl.c and you don't
use acpi-custom-DSDT.patch instead.
Really, it look good for me.  What say

$ patch -p1 -i /path/to/acpi-custom-DSDT.patch
in the linux-2.5.69 directory ?

Re: custom dsdt with 2.5

[roychris-GANU6spQydw]

Bruno, your patch is rejected by the 2.5.69. But thanks to your help, it's
working now. I can use my custom dsdt.
But my problem is not solve. When I try the 3 sleep state, all my peripherics
are shutted down (but I don't have the sleep LED on), but when I want to resume,
only the cdrom wakes up ! And when I try the 4 state, after the driver frees the
memory, I have a very fast (too fast to read it) message that is indefinitively
repeated. I think that it's a dump mem (something like kernel panic maybe).

How can I have this message ?
Does anyone have the same troubles ?

acpi-custom-DSDT.patch should work, (but I have not tested it) is
not my patch.

I can not tell because I have an hardware failure in my laptop, but
I should bought a new one soon.
