Re: [Bug #13318] AGP doesn't work anymore on nforce2

[Karsten Mehrhoff]

Hi all,

Today i compilied the new kernel 2.6.31 and everything works ok.
Maybe it's related to other changes in the generic.c file.

So everything works ok for me with AGP in 2.6.31.
I do not get the problem like it was in 2.6.30.x


2.6.31:

0e64a0c has this cleanup, which isn't equivalent to the previous code:

@@ -779,11 +834,12 @@ static int powernow_k8_cpu_init_acpi(struct powernow_k8_data *data)
 		goto err_out;
 	}
 
-	if ((data->acpi_data.control_register.space_id != ACPI_ADR_SPACE_FIXED_HARDWARE) ||
-		(data->acpi_data.status_register.space_id != ACPI_ADR_SPACE_FIXED_HARDWARE)) {

 	}
 
This got fixed in 2c701b1 in 2.6.31-rc8, so this is most likely the 
problem that Kurt was encountering.

Kurt, could you try 2.6.31 and see if you still experience the issue?  If 
not, this can be closed.

Please look at the patch I attached to the bug report.  There is
other code that is not equivalent.  It's in comment #17:
http://bugzilla.kernel.org/show_bug.cgi?id=13780#c17

And the patch itself:
http://bugzilla.kernel.org/attachment.cgi?id=23048

This patch fixes my problem.

I also noticed this difference (comment #18), patched it, and
tried it.  This is not the issue.  Also note that I tested the
2.6.31-rc9 kernel which still had the problem.

The bug report might be a little confusing since after comment #18
there are older mails pasted in the bug report.

Ah, I hadn't noticed you attached a patch there that fixes the issue for 
you.  Is it en-route to Dave Jones so that it can make its way upstream?

I have no idea, so I would guess not.

Thanks for that Kurt.  I'll get this merged and on the way to
Linus & stable today.
