Boot with "lapic" to force-enable the local APIC.

Automatically overriding the BIOS was considered a bug in
some quarters (mainly ACPI), so the code was changed to
require a kernel boot option to enable the override.

BIOSen suck.

Use kernel parameter: lapic

It was decided the kernel should not automatically use local apic if 
bios hasn't activated it.

Hi,

after upgrading to 2.6.9-rc4 I'm getting the following message in dmesg:

No local APIC present or hardware disabled

2.6.9-rc3 and older kernels did not show this message. They showed:
 Local APIC disabled by BIOS -- reenabling.
 Found and enabled local APIC!

Any hints ?

Machine is an Acer Travelmate 291lci laptop.

Config is attached. Do you need any other information?

Regards, Sebastian

 As you've already been told, the local APIC is not being enabled by
default anymore.  I think this change may be unfortunate for users, so
I've proposed the change to be applied for systems using ACPI and then
verbosely, so that the reason for the APIC being kept disabled is clear.  
Unfortunately I have no system available for testing that uses ACPI, so
I'm asking whether you could participate in testing of the following
patch.  With the patch applied, you should either get a warning or the
local APIC running (e.g. if you disable ACPI by specifying "noacpi").  
Does the patch work for you?  For anyone else?

There are systems, such as the P3-based Dell Inspirons and Latitutes
that caused the dmi blacklist to be implemented, that fail whether
they're using APM or ACPI. So in the interest of consistency, we should
either always automatically override the BIOS, requiring "nolapic" on
broken systems, or never automatically override the BIOS, requiring
"lapic" on systems that work but have stupid BIOSen.

None of this is ACPI-specific, so I don't like the idea of tying
auto-enable/disable to ACPI.

Hi,

i tested your patch, but it did not apply correctly to a clean 2.6.9-rc4
tree for me. (patch -Np1 -i ../patch-2.6.9-rc4-lapic-5)

I applyed it manually, and when rebooting, i get the following:
 Local APIC won't be reenabled, ...
 You can...

When booting with 'pci=noacpi':
 Local APIC won't be reenabled, ...
 You can...

When booting with 'acpi=off':
 no output when running dmesg|grep -i apic

 Thanks, these are expected results.  Note that with 2.6.9 someone decided
to disable APIC-related messages by default, so you won't get any
information from the log unless you pass e.g. "apic=debug".

 It's a pity another useful feature gets disfavored due to firmware bugs
in newer systems.

 I hope I won't hit the length limit of the command line this way, sigh...

 Anyway, if this is going to stay in, I think code needs to be cleaned up
to get rid of dead bits and inaccurate comments.  Here's my proposal.  
Does it make sense?  I hope so.

Looks completely wrong to me. The BIOS disabled it or left it disabled
because they chose not to support it. We enabled it and then relied on
bios functionality.

DMI scan may still be relevant. Previously we used it to
override the default force-enable policy. Now we may still
need it to force-disable the lapic on systems that boot with
it enabled but malfunction if it's used. (I don't know of
any, but given BIOS history, they aren't impossible.)
So the comment doesn't need to change.

I agree with Alan that accusing the BIOS of being buggy is unwarranted.
The text should just state the obvious:

The local APIC was disabled by the BIOS.
You can enable it with "lapic".

To implicitly include P4 and K8, just change this to:
Intel P6 and later, and AMD K7 (Model > 1) and later

Show me a PC standards document that says this - there are none.

If you switch video mode without using the BIOS then the BIOS video
calls are not guaranteed to work. Its the same thing.

Looks good to me in this form.

 We don't disable APIC right now, so this may only become true once it's
done (e.g. disable_local_APIC() is called from here).

> So the comment doesn't need to change.

 I don't think keeping an inaccurate comment is good.  Simply add it back 
if it becomes relevant.

 I disagree.  If the firmware performs any actions on hardware without
asking the OS for permission, it *must* be prepared for it to be in any
possible state and handle it correctly, including any transitional states
(as it does respect spinlocks).  Otherwise it's buggy.

 Alan, referring to your statement: it's like stating we must only use the
text mode of the display adapter, because that's the state it's left in by
the firmware and it may not expect any other state.

 I don't insist on any particular message though -- the following one
should hopefully suit you as more neutral (but you risk questions: "Why
doesn't Linux enable the APIC anymore?").

But in this case the BIOS explicitly disabled the local APIC. It may
have a legitimate reason for doing so (e.g. old #SMM code), so if the
Linux kernel overrides that disablement and things break, it really is
the kernel's fault not the BIOS'.
