[PATCH 0/5] x86: Reduce memory usage for large count NR_CPUs fixup

[travis]

Fixup change NR_CPUS patchset by rebasing on 2.6.24-rc8-mm1
from 2.6.24-rc6-mm1) and adding changes suggested by reviews.

Additionally, some new config options have been added to enable
large SMP configurations.

[PATCH 1/5] x86: Change size of node ids from u8 to u16 fixup

[travis]

[-- Attachment #1: big_nodeids-fixup --]
[-- Type: text/plain, Size: 2479 bytes --]

Change the size of node ids for X86_64 from 8 bits to 16 bits
to accomodate more than 256 nodes.

Introduce a "numanode_t" type for x86-generic usage.

Fixup:

Size of memnode.embedded_map needs to be changed to
accomodate 16-bit node ids as suggested by Eric.

V2->V3:
    - changed memnode.embedded_map from [64-16] to [64-8]
      (and size comment to 128 bytes)

V1->V2:
    - changed pxm_to_node_map to u16
    - changed memnode map entries to u16

Do we really need numanode_t in userspace? I'd rather not, especially
when its type is dependent on MAX_NUMNODES. Wrap with #ifdef __KERNEL__.

that is wrong, you can not change pxm_to_node_map from int to u8 or u16.

int acpi_map_pxm_to_node(int pxm)
{
        int node = pxm_to_node_map[pxm];

        if (node < 0){
                if (nodes_weight(nodes_found_map) >= MAX_NUMNODES)
                        return NID_INVAL;
                node = first_unset_node(nodes_found_map);
                __acpi_map_pxm_to_node(pxm, node);
                node_set(node, nodes_found_map);
        }

        return node;
}

node will will be always 255 or 65535

please keep that to int.

I got
SART: PXM 0 -> APIC 0 -> Node 255
SART: PXM 0 -> APIC 1 -> Node 255
SART: PXM 1 -> APIC 2 -> Node 255
SART: PXM 1 -> APIC 3 -> Node 255

Yeah, NID_INVAL is negative so no unsigned type will work here, 
unfortunately.  And that reduces the intended savings of your change since 
the smaller type can only be used with a smaller CONFIG_NODES_SHIFT.

I assume this is a typo and those proximity mappings are actually from the 
SRAT.

SRAT for processor only have
PXM and APIC id. setup_node(pxm) will get node id for pxm, start from 0...

Excuse my ignorance but why wouldn't this work:

static numanode_t pxm_to_node_map[MAX_PXM_DOMAINS]
                                = { [0 ... MAX_PXM_DOMAINS - 1] = NUMA_NO_NODE };

	   numanode_t node = pxm_to_node_map[pxm];

	   if (node != NUMA_NO_NODE) {

or change:
	#define NID_INVAL       (-1)
to
	#define NID_INVAL       ((numanode_t)(-1))
...
	   if (node != NID_INVAL) {

Though why there two "node invalid" values I'm not sure... ?

And btw, shouldn't the pxm value be sized to numanode_t size as well?
Will it ever be larger than the largest node id?

Because NUMA_NO_NODE is 0xff on x86.  That's a valid node id for 
configurations with CONFIG_NODES_SHIFT equal to or greater than 8.

> 	   if (node != NUMA_NO_NODE) {

Wrong, this should be

	node == NUMA_NO_NODE

The net result of this is that if a proximity domain is looked up through 
acpi_map_pxm_to_node() and already has a mapping to node 255 (legal with 
CONFIG_NODES_SHIFT == 8), this function will return NID_INVAL since the 
weight of nodes_found_map is equal to MAX_NUMNODES.

You simply can't use valid node id's to signify invalid or unused node 
ids.

That's the equivalent of your NUMA_NO_NODE code above.  The fact remains 
that (numanode_t)-1 is still a valid node id for MAX_NUMNODES >= 256.

So, as I said in my initial reply, the only way to get the savings you're 
looking for is to use u8 for CONFIG_NODES_SHIFT <= 7 and then convert all 
NID_INVAL users to use NUMA_NO_NODE.

Additionally, Linux has always discouraged typedefs when they do not 
define an architecture-specific size.  The savings from your patch for 
CONFIG_NODES_SHIFT == 7 would be 256 bytes for this mapping.

It's simply not worth it.

Section 6.2.9 of ACPI 2.0 states that PXM's return an integer, so that 
would be non-conforming to the standard.

Additionally, PXM's are not nodes, so casting them to anything called 
numanode_t shows the semantic flaw in your patch.

Perhaps numanode_t should be set to u16 if MAX_NUMNODES > 255 to
allow for an invalid value of 255? 

#if MAX_NUMNODES > 255
typedef u16 numanode_t;
#else
typedef u8 numanode_t;
#endif

Yes, I agree.  I'll do the changes you're suggesting.

So are you saying that I should just use u16 for all node ids whether
CONFIG_NODES_SHIFT > 7 or not?  Othersise, I would think that defining a
typedef is a fairly clean solution.

A quick grep shows that there are 35 arrays defined by MAX_NUMNODES in
x86_64, 38 in X86_32 (not verified.)  So it's not exactly a trivial
amount of memory.

just use int for node id, and -1 will be NON_VALID...
or s16?

Throughout the NUMA code you need a way to distinguish between an invalid 
mapping and an actual node id.  NID_INVAL is used to say there are no 
additional node ids available for this system, the pxm-to-node mapping 
doesn't yet exist, etc.

You can't get away with using a magic positive integer with those 
semantics because CONFIG_NODES_SHIFT determines MAX_NUMNODES.  All 
nodemasks will have that many bits in their struct.  So 255 will always be 
a valid node id for shifts of 8 or larger.  It isn't feasible to say for 
these types of systems (or ia64 where the default shift is 10) that 255 is 
some magic node id that means its invalid.

NID_INVAL is the only way to signify an invalid node id and that has 
always been done with -1.  So objects that store node ids that have the 
possibility of being invalid must be signed.  The only time you can use 
unsigned objects are when you are guaranteed to have valid node ids.

You're assuming that CONFIG_NODES_SHIFT will never been larger than that 
and you still wouldn't be able to use your new numanode_t for anything 
that could return NID_INVAL.

You're spinning the argument.  Most of those arrays are not simply 
returning node ids; most are returning structs or are arrays of unsigned 
long type that return addresses.  Those are unaffected by your change.  
Others are initdata and is freed after boot anyway.

The handful of arrays thoughout the source that return node ids and are 
not initdata would only save MAX_NUMNODES number of bytes with your 
change for 8-bytes instead of 16-bytes.  You're right, you might save a 
KB of memory with the change.  It's not worth it, especially since they 
need to be signed anyway.

[PATCH 2/5] x86: Change NR_CPUS arrays in numa_64 fixup

[travis]

[-- Attachment #1: NR_CPUS-arrays-in-numa_64-fixup --]
[-- Type: text/plain, Size: 7272 bytes --]

Change the following static arrays sized by NR_CPUS to
per_cpu data variables:

	char cpu_to_node_map[NR_CPUS];


Signed-off-by: Mike Travis <travis@sgi.com>
Reviewed-by: Christoph Lameter <clameter@sgi.com>
---
fixup:

  - Split cpu_to_node function into "early" and "late" versions
    so that x86_cpu_to_node_map_early_ptr is not EXPORT'ed and
    the cpu_to_node inline function is more streamlined.

  - This also involves setting up the percpu maps as early as possible.

  - Fix X86_32 NUMA build errors that previous version of this
    patch caused.

V2->V3:
    - add early_cpu_to_node function to keep cpu_to_node efficient
    - move and rename smp_set_apicids() to setup_percpu_maps()
    - call setup_percpu_maps() as early as possible

V1->V2:
    - Removed extraneous casts
    - Fix !NUMA builds with '#ifdef CONFIG_NUMA"

[PATCH 3/5] x86: Change bios_cpu_apicid to percpu data variable fixup

[travis]

[-- Attachment #1: change-bios_cpu_apicid-to-percpu-fixup --]
[-- Type: text/plain, Size: 2768 bytes --]

Change static bios_cpu_apicid array to a per_cpu data variable.
This includes using a static array used during initialization
similar to the way x86_cpu_to_apicid[] is handled.

There is one early use of bios_cpu_apicid in apic_is_clustered_box().
The other reference in cpu_present_to_apicid() is called after
smp_set_apicids() has setup the percpu version of bios_cpu_apicid.

Adds and increases some config variables to accomodate larger SMP
configurations:

	NR_CPUS:      max limit now 4096
	NODES_SHIFT:  max limit now 9
	THREAD_ORDER: max limit now 3
	X86_SMP_MAX:  say Y to enable possible cpus == NR_CPUS

Could you please elaborate, why this is needed and put more info about
this requirement into this patch description?

People worked hard to push data allocation from stack to heap to make 
THREAD_ORDER of 0 and 1 possible. So why increase it again and why does this
help scalability?

Many thanks and Best Regards

THREAD_ORDER can also be used to consolidate the stack size with the 
choices available for i386. In that cases the choices are 0 and 1.

The primary problem arises because of cpumask_t local variables.  Until I
can deal with these, increasing NR_CPUS to a really large value increases
stack size dramatically.

Here are the top stack consumers with NR_CPUS = 4k.

First I think you have to get rid of the THREAD_ORDER stuff -- your
goal of the whole patchkit after all is to allow distributions to
support NR_CPUS==4096 in the standard kernels and I doubt any
distribution will over chose a THREAD_ORDER > 1 in their 
standard kernels because it would be too unreliable on smaller
systems.

These should run single threaded early at boot so you can probably just make
the cpumask_t variables static __initdata

These above are the real pigs. Fortunately they are all clearly
slowpath (except perhaps show_shared_cpu_map) so just using heap
allocations or when needed bootmem for them should be fine.

x86-64 always has 8k stacks and separate interrupt stack. As long
as the calls are not in some stack intensive layered context (like block
IO processing path etc.) <3k shouldn't be too big an issue.

BTW there is a trick to get more stack space on x86-64 temporarily:
run it in a softirq. They got 16k stacks by default. Just leave
enough left over for the hard irqs that might happen if you don't
have interrupts disabled.

One way if you don't care about indirect/asm calls is to use cflow and do
some post processing that adds up the data from checkstack.pl

The other way is to use mcount, but only for situations you can reproduce
of course. I did have a 2.4 mcount based stack instrumentation patch
some time ago that I could probably dig out if it was useful.

Thanks for the great feedback Andi.  Since cpumask changes are the next
item on my list after NR_CPUS (and friends) are dealt with, perhaps I
could move the THREAD_ORDER stuff to the "Kernel Hacking" area for the
interim?

And yes, I'm interested in any tools to help accumulate information.

Btw, there are 116 functions now that have >= 1k stack size.

Cheers,
Mike

To correct myself: this is not true for build_sched_domains() which can
be triggered from sysfs.

How big is the stack during early startup?

THREAD_ORDER (runs on init_stack's stack)

early init stack could be increased in theory with some effort,
but since that is all single threaded anyways just a few strategic
static __initdata's should be simple enough.

The problem in kernel/sched.c:isolated_cpu_setup() is an array of
NR_CPUS integers:

    static int __init isolated_cpu_setup(char *str)
    {
	    int ints[NR_CPUS], i;

	    str = get_options(str, ARRAY_SIZE(ints), ints);

Since isolated_cpu_setup() is an __init routine, perhaps we could
make that ints[] array static __initdata?

The build_sched_domains() may require more thought and code rework.
See also the lkml discussion of my patches that reworked the cpuset
code implementing 'sched_load_balance' calling into build_sched_domains
() via kernel/sched.c:partition_sched_domains().  This is not performance
critical code, fortunately.

That or use alloc_bootmem / free_bootmem

nack on kernel stack bloat. We worked hard to get the kernel stack 
footprint down to 4K on x86. (and it is 4K on most distros, despite 
there still being a legacy 8K stack size) No way are we going to throw 
away all that now ...

i've bisected a boot failure down to this patch (sans the THREAD_ORDER 
bits): it causes an instant reboot of the 64-bit kernel upon bootup. 
Failing config attached.

Thanks.  I had pulled this from the patch as ak suggested.  But it seems
that it's finding real errors that need to be fixed.

Thanks Ingo! 

I've pulled the THREAD_ORDER change from my next version of the patch.
Seems SMP_MAX is just not ready for prime time yet.

One problem that I'm having appears to be that the !NUMA config of the
current -mm version also doesn't boot so I haven't been able to verify
that.  (At least it doesn't seem to make it worse... ;-)

Thanks,
Mike

Are you sure that debug option is generally useful enough
to merge? It seems very specific to your patchkit, but I'm not
sure it would be worth carrying forever in the kernel.

Better would be probably to just unmap those areas anyways.

I thought for a round of testing it'd be worthwhile, particularly
testing randconfig.  The next version of percpu changes are coming
soon and I can remove them then.  Ideally, you are right, it'd
be nice to not have the percpu memory mapped for processors that are
not present.

One thing that comes into play is that (soon) the boot_pda will be
in the per_cpu area and it's maintained for all "possible" cpus as
it keeps track of some info on "off-lined" cpus.  What I was thinking
is that perhaps no memory is allocated (and mapped) until a cpu
becomes not only possible, but probable.  This means that until a
cpu is brought online, or discovered via ACPI, then there is no percpu
area and access to an invalid percpu area causes a kernel fault.

Thanks,
Mike

Its generally useful also for the cpu_alloc changes that may lead 
to the moving around of early initialization code for consolidation of 
code between i386 and x86_64 once Mike's initial patchset is in.
