ACPI patch status (2.6)

ACPI patch status (2.6)

[Len Brown]

FYI,
The following changes are currently in the ACPI test tree
http://linux-acpi.bkbits.net/linux-acpi-test-2.6.0
available for testing before push to 2.6.0

The associated plain patches are also available here:
ftp.kernel.org:/pub/linux/kernel/people/lenb/acpi/patches/test/

Yes, it has been too long since the last push into 2.6.
The good news is that we'll have finally got 2.6 back in sync with 2.4.

If you seen any regressions, please let me know.

thanks,
-Len

Thanks.  I don't see the patch I submitted (buffer overflow in resource

Always learning, but the best process I know goes something like below.
In summary, the mailing list is great, but if you want to be sure an
issue and its fix get properly handled and don't fall through the
cracks, then bugzilla is your friend.

thanks,

My ACPI tolerant patch is not included. Without this it will not boot

Thanks Andi,
I've included your "PIC fallback and SMP boxes" note below to give
others background if they haven't seen it yet.

My  understanding was that the acpi_tolerant patch is in response to
Andrew de Quincy's "Full dropback to PIC mode" patch -- the one that
creates pic.c.  That change is in the mm tree, but not yet in 2.4, 2.6,
or the acpi 2.4 or 2.6 trees.

If I'm confused and you believe that the acpi_tolerant patch is needed
for the current acpi tree to boot on some SMP servers, please straighten
me out.

thanks,
-Len

Hi,

We had good success with Andrew's PIC fallback patches on SuSE Linux.
A lot of boxes that needed pci=noacpi or acpi=off before work now.

Unfortunately there were also some regressions, mostly on bigger SMP 
boxes (e.g. some HP servers). What usually happened was that some
unimportant device like one USB port would fail to set or get an
interrupt.

That would cause a full PIC mode fallback, which is not a good idea
on a SMP system and usually results in a failed boot.

People didn't notice the not working USB port before (or maybe it 
worked anyways).

I did a bit of an hack to work around this now. On a SMP system PIC 
mode fallback is probably not a good idea because it will perform awful
and more likely not work at all. This patch checks
if the box is a "true" SMP system (not just an uniprocessor box
with huperthreading), and if yes enables tolerant mode. Tolerant
mode means we don't do PIC fallback for failing to set an ACPI link.

This could be more improved, e.g. acpi_pci_get_prt_list should
probably also tolerate partial failure.

Another bigger problem we have with the PIC fallback is that there
are a some chipsets that don't like it when you first set a few
interrupts in APIC mode and then go back to PIC mode (e.g. 
that's the case on all NForce3 and some VIA boards). I'm not sure what 
to do with them yet. For our use for x86-64 I added an hack to always
force
PIC mode for Nvidia and VIA, but that's clearly an hack.

The patch is for a SuSE tree, will probably not apply directly to plain
2.4.

Yep. But that tree needs acpi-tolerant too

No, you're right. It only makes sense with PIC fallback. But PIC 
fallback is included in your test tree, right? If yes then you
should merge acpi-tolerant too.

BTW IMHO you should merge both (PIC mode and the other fixes including
acpi-tolerant) ASAP to mainline. There are tons of ACPI bug reports for 
2.6 all the time that would be fixed by them. It would be much better to
test there than in some test tree that nobody uses anyways. That would
also give the patches a much better test.

RE: ACPI patch status (2.6)

[Moore, Robert]

Nate,

I was out on medical leave for 3 months, and I'm busy catching up on
patch integration and bug fixes for ACPI CA.

I'm looking at the resource fixes for the next release, hopefully this
week.
Bob

Thanks.  I don't see the patch I submitted (buffer overflow in resource
lists) below.  Is there a good facility where you track patches that I
should submit them instead?
