2.5.45 / boottime oops (pnp bios I think)

2.5.45 / boottime oops (pnp bios I think)

[CaT]

When I unselect PNP BIOS the kernel boots fine. With it I get the
oops below. Please note that it was typed out manually and that that was
all that I could get as I could not scroll up or down in any way.

The PC is a Gateway laptop.

If you need more info, please holler.

Thanks. I've added a rule to my tree to disable the pnp bios on that box

Instead of adding your PnP BIOS to the black list, I may know a way to 
support it completely even though it is broken.

To prove this idea could you please do the following:

1.) apply patch 1 (attached below) to a clean kernel (2.5.45).  Compile the 
kernel with PnP BIOS support and list the last few messages that start with 
"pnp!!!:" before it panics.  You probably will want to have kernel debugging
off so it doesn't scroll the messages off the screen.

2.) Apply patch 2 (attached below) to a clean kernel (2.5.45).  Compile the 
kernel with PnP BIOS support.  It should start up completely without a panic.  
This is not a complete fix however.  Anyway attach a copy of the output from 
dmesg.

If my theory is correct I will have a fix out soon.

thanks,
Adam

It can be infered from the two above excerpts that the general protection fault
occured when the pnp bios protocol reached node 0x13.  This node, pnp id
PNP0f13, is of course a standard mouse port.  If you look at the output of 
lspnp for my system, the following can be seen.

12 PNP0f13 input device: mouse
    flags: [no disable] [no config] [static]
    allocated resources:
	irq 12 [high edge]

Notice the flags "No Config" and "Static".  This device can not be configured
by the pnpbios and only contains static resource information.  So the question
is why do some systems handle getting dynamic information from static devices
and others don't.  I believe that some PnP BIOSes are broken and are unable to
handle calls that do not make sense.  In other words, requesting dynamic
information from a static device is pointless becuase it could only contain
static information.  The idea that this is the cause of the general protection
fault is further supported by the fact that not every node had this problem.

It actually makes sense for a bug like this to go unnoticed in other operating
systems.

The following describes the Microsoft Windows PnP boot process:

-During boot real mode calls are made.
-only static configuration requests are made, no dynamics yet
-then the protect mode configuration manager starts
-then dynamic calls can be made

* This would imply that dynamic calls will only be made if neccessary.  Making
a dynamic call on a static device would therefore never happen.

This patch will make the PnP BIOS protocol follow these conventions:

1.) only static information requests are made during the initial device tree
building process.
2.) pnp flags are used to see if a device is static or cannot be configured.
3.) if the device is static the protocol will prevent any dynamic calls
4.) all sony viao and other dmi scan restrictions will be removed.
5.) if the device is indeed dynamic, dynamic calls will be made to update
the status after resources are set or the device is disabled.

More stuff related to this is on the way but this patch should make the pnpbios
driver fully functional.  It is against 2.5.45 but should work with 2.5.46 as
well.  It adds peliminary support for PnP BIOS flags.  Eventually I'll export
these to a user interface.

Please feel free to send any questions or comments.  The patch is below.

Thanks,
Adam

Oops, I forgot to fix the pnpbios proc interface for this problem.  I have
to look into it some more.  None the less this is not a big problem.  If
it boots you're in good shape.

Could you, however send me the output of lspnp for /proc/bus/pnp/boot/13.
This will not fault.  Also could you try lspnp on /proc/bus/pnp/14.  If
all is well this one should not fault.

by the way

/proc/bus/pnp/*.* = current
/proc/bus/pnp/boot/*.* = boot

current config has the problem but boot does not.  I'll work on a patch to
fix this.

Thanks,
Adam

This is all that I could get:

The patch lets me boot just fine. (Woo) One hassle though, doing
lspci -v 13 or cat /proc/bus/pnp/13 causes an oops. I presume it's the

Cool, thanks. :)

Neither faulted.

Sweet. Thanks. :)

We should really have an extra taint flag for 'We have run untrusted BIOS 
code'.

Relatively pointless given that there are more and more boxes out there
that won't boot without ACPI these days.

There are also more and more boxes out there which won't run X without the
nvidia driver loaded. Does that mean we shouldn't bother to record that 
information either?

I'm not necessarily suggesting we should automatically ignore all reports 
with the 'BIOS' taint flag set as we do the 'Proprietary' flag; just that 
it should be reported.

Crap. The OSS driver works fine, just not as accelerated.

I don't see what it would buy us.

Ah. It must have got a lot better since I last tried it then -- last time I
looked it wouldn't work on the newer chips at all. I had to use the vesa 
driver instead.

>  I don't see what it would buy us. 

It makes it clear that untrusted and undebuggable code is running, just 
like the 'Proprietary' flag does.

You only need the binary driver for 3D support.  XFree86 runs fine 
without it for 2D.
