	[BUG] x86: bootmem broken on SGI UV

Recent community kernels do not boot on SGI UV x86 hardware with
more than one socket.  I suspect the problem is due to recent 
bootmem/e820 changes.

What is happening is the e280 table defines a memory range.

 BIOS-e820: 0000000100000000 - 0000001080000000 (usable)

The SRAT table shows that memory range is spread over two nodes.

 SRAT: Node 0 PXM 0 100000000-800000000
 SRAT: Node 1 PXM 1 800000000-1000000000
 SRAT: Node 0 PXM 0 1000000000-1080000000

Previously, the kernel early_node_map[] would show three entries
with the proper node.
                                                                                
[    0.000000]     0: 0x00100000 -> 0x00800000
[    0.000000]     1: 0x00800000 -> 0x01000000
[    0.000000]     0: 0x01000000 -> 0x01080000

The problem is recent community kernel early_node_map[] shows 
only two entries with the node 0 entry overlapping the node 1
entry.

    0: 0x00100000 -> 0x01080000
    1: 0x00800000 -> 0x01000000

This results in the range 0x800000 -> 0x1000000 getting freed twice
(by free_all_memory_core_early()) resulting in nasty warnings.

 Queued invalidation will be enabled to support x2apic and Intr-remapping.

I have not tracked the exact change that caused the regression, but suspect
it involves the recent bootmem/e820 changes.

Attached is the full boot output.

[PATCH] x86, numa: Fix cross nodes mem conf

Russ reported SGI UV is broken recently. He said:

| The SRAT table shows that memory range is spread over two nodes.
|
| SRAT: Node 0 PXM 0 100000000-800000000
| SRAT: Node 1 PXM 1 800000000-1000000000
| SRAT: Node 0 PXM 0 1000000000-1080000000
|
|Previously, the kernel early_node_map[] would show three entries
|with the proper node.
|
|[    0.000000]     0: 0x00100000 -> 0x00800000
|[    0.000000]     1: 0x00800000 -> 0x01000000
|[    0.000000]     0: 0x01000000 -> 0x01080000
|
|The problem is recent community kernel early_node_map[] shows
|only two entries with the node 0 entry overlapping the node 1
|entry.
|
|    0: 0x00100000 -> 0x01080000
|    1: 0x00800000 -> 0x01000000

After looking at the changelog, it turns out it is broken for a while by
following commit

|commit 8716273caef7f55f39fe4fc6c69c5f9f197f41f1
|Author: David Rientjes <rientjes@google.com>
|Date:   Fri Sep 25 15:20:04 2009 -0700
|
|    x86: Export srat physical topology

before that commit, register_active_regions() is called SRAT memory entries.

Try to use nodememblk_range[] instead of nodes[].

For stable tree: from 2.6.33 to 2.3.36 need this patch by
changing memblock_x86_register_active_regions() with e820_register_active_regions()

Will this be included in 2.6.36?  It is needed for boot in order for UV
systems to boot.

Thanks,

yes, it is needed for 2.6.33 .34 .35 .36

It is too late for put in 2.6.36. Linus already had -rc7, and assume he will have final .36 this week.

Russ reported SGI UV is broken recently. He said:

| The SRAT table shows that memory range is spread over two nodes.
|
| SRAT: Node 0 PXM 0 100000000-800000000
| SRAT: Node 1 PXM 1 800000000-1000000000
| SRAT: Node 0 PXM 0 1000000000-1080000000
|
|Previously, the kernel early_node_map[] would show three entries
|with the proper node.
|
|[    0.000000]     0: 0x00100000 -> 0x00800000
|[    0.000000]     1: 0x00800000 -> 0x01000000
|[    0.000000]     0: 0x01000000 -> 0x01080000
|
|The problem is recent community kernel early_node_map[] shows
|only two entries with the node 0 entry overlapping the node 1
|entry.
|
|    0: 0x00100000 -> 0x01080000
|    1: 0x00800000 -> 0x01000000

After looking at the changelog, Found out that it has been broken for a while by
following commit

|commit 8716273caef7f55f39fe4fc6c69c5f9f197f41f1
|Author: David Rientjes <rientjes@google.com>
|Date:   Fri Sep 25 15:20:04 2009 -0700
|
|    x86: Export srat physical topology

Before that commit, register_active_regions() is called for every SRAT memory
entry right away.

Try to use nodememblk_range[] instead of nodes[].

For stable tree: from 2.6.33 to 2.3.36 need this patch by
changing memblock_x86_register_active_regions() to e820_register_active_regions()

Anything that is worth tagging for stable is worth fixing before the
final release (probably Wednesday).

But I do want it tested and confirmed, and acked by lots of people.
And preferably get it through the normal channels too.

-tip uses memblock APIs. If this happens with vanilla -git as well then 
we need a bootmem backport for the fix.

And to answer your question: yes, we can queue it up for -final as well 
if it's a recent regression - 'doesnt boot at all' bugs are nasty. But 
i'm not sure this is a bootmem problem so please double check vanilla 
v2.6.36-rc7 as well.

Thanks,

The 36-rc7 kernel does not boot at all either.  I don't have any decent
debug tools to dig in further.  It does fail on the same machine that
Russ was testing with, but passes on any that have a single blade as
the kernel Russ first identified as being a problem had.  Based upon my
vague recollection of the boot messages, it appears to fail in a similar
point in boot.  I would assume it is a similar problem.

Thanks,
Robin

2.6.35 fails as well.  I will bisect for as long as time permits.

That's really bad. If this means that you have not booted vanilla 
mainline on UV in that timeframe _at all_, and that it was perma-broken 
since 2009 when that commit Yinghai identified went upstream, then 
there's little point in squeezing this fix into v2.6.36-final.

-rcs are strictly for regression fixes.

If you want upstream to care about you then you absolutely have the duty 
to at minimum test latest mainline ...

Upstream boots on many UV systems.  Some have more constrained memory
and end up with this weird mapping which causes the problem.  I am not
sure how many of the machines end up with this config, but it is far
from all of them.

Jack does build and boot a kernel every night on many different
configurations, just not this one.  I believe he and Russ are working
on getting this configuration into his nightly testing.

Russ reported SGI UV is broken recently. He said:

| The SRAT table shows that memory range is spread over two nodes.
|
| SRAT: Node 0 PXM 0 100000000-800000000
| SRAT: Node 1 PXM 1 800000000-1000000000
| SRAT: Node 0 PXM 0 1000000000-1080000000
|
|Previously, the kernel early_node_map[] would show three entries
|with the proper node.
|
|[    0.000000]     0: 0x00100000 -> 0x00800000
|[    0.000000]     1: 0x00800000 -> 0x01000000
|[    0.000000]     0: 0x01000000 -> 0x01080000
|
|The problem is recent community kernel early_node_map[] shows
|only two entries with the node 0 entry overlapping the node 1
|entry.
|
|    0: 0x00100000 -> 0x01080000
|    1: 0x00800000 -> 0x01000000

After looking at the changelog, Found out that it has been broken for a while by
following commit

|commit 8716273caef7f55f39fe4fc6c69c5f9f197f41f1

Before that commit, register_active_regions() is called for every SRAT memory
entry right away.

Try to use nodememblk_range[] instead of nodes[].

For stable tree: from 2.6.33 to 2.3.36 need this patch

-v3: update to linus's tree.

Before that commit, register_active_regions() is called for every SRAT memory

Use nodememblk_range[] instead of nodes[] in order to make sure we
capture the actual memory blocks registered with each node.  nodes[]
contains an extended range which spans all memory regions associated
with a node, but that does not mean that all the memory in between are
included.

Sorry I hadn't seen this thread earlier, I wasn't cc'd on it.

Thanks for confirming.  I don't have access to any systems on which I
can verify this condition myself, but I spent some fairly serious time
time morning on code inspection, and I'm pretty sure I grok what this
patch does and that it is the right thing.

This is not just an SGI UV problem but will in fact bite any system
which has nodes with interlaced memory blocks (for example block 0
belongs to node 0, block 1 belongs to node 1, and then block 2 belongs
to node 0 again.)

There are multiple loops after these which rely on the nodes[] range,
but in fact they rely on exactly this loop to have registered the
relevant memory ranges for the node, so fixing this loop fixes the
subsequent ones.  Of course, it *seriously* begs the question why
nodes[] carry a range at all (well, other than to support bootmem, which
seems like yet another good reason to finish off bootmem.)

Any help in testing would be highly appreciated.  Please feel free to
involve anyone else who would likely have access to the kind of large
NUMA x86 systems which are likely to be affected.

x86, numa: For each node, register the memory blocks actually used

Russ reported SGI UV is broken recently. He said:

| The SRAT table shows that memory range is spread over two nodes.
|
| SRAT: Node 0 PXM 0 100000000-800000000
| SRAT: Node 1 PXM 1 800000000-1000000000
| SRAT: Node 0 PXM 0 1000000000-1080000000
|
|Previously, the kernel early_node_map[] would show three entries
|with the proper node.
|
|[    0.000000]     0: 0x00100000 -> 0x00800000
|[    0.000000]     1: 0x00800000 -> 0x01000000
|[    0.000000]     0: 0x01000000 -> 0x01080000
|
|The problem is recent community kernel early_node_map[] shows
|only two entries with the node 0 entry overlapping the node 1
|entry.
|
|    0: 0x00100000 -> 0x01080000
|    1: 0x00800000 -> 0x01000000

After looking at the changelog, Found out that it has been broken for a while by
following commit

|commit 8716273caef7f55f39fe4fc6c69c5f9f197f41f1
|Author: David Rientjes <rientjes@google.com>
|Date:   Fri Sep 25 15:20:04 2009 -0700

|    x86: Export srat physical topology

Before that commit, register_active_regions() is called for every SRAT memory
entry right away.

Use nodememblk_range[] instead of nodes[] in order to make sure we
capture the actual memory blocks registered with each node.  nodes[]
contains an extended range which spans all memory regions associated
with a node, but that does not mean that all the memory in between are
included.
