Hi Mike!

Since commit fa3354e4ea39 (mm: free_area_init: use maximal zone PFNs rather
than zone sizes), I get the following BUG on Alpha (an AlphaServer ES47 Marvel)
and loading userspace leads to a segfault:

(I didn't notice this for a long time because of other unrelated regressions,
the pandemic, changing jobs, ...)

I haven't tried reproducing this on other machines or QEMU, but I'd be glad to
if that helps.

Any ideas?

Thanks,
Matt

I suspect there will be more surprises down the road :)

If it's reproducible on QEMU I can debug it locally.
 
> Any ideas?

It seems like memory map is not properly initialized. Can you enable
CONFIG_DEBUG_MEMORY_INIT and add mminit_debug=4 to the command line. The
interesting part of the log would be before "Memory: xK/yK available ..."
line.

Hopefully it'll give some clues.

Sincerely yours,
Mike.

I think that the issue is that memory marked as used in memcluster is never
added to memblock and it skews node/zone sizing calculations.

Can you try this patch:

Thanks, this patch fixes it. With the patch applied, I see

Zone ranges:
  DMA      [mem 0x0000000000000000-0x00000fffffffdfff]
  Normal   empty
Movable zone start for each node
Early memory node ranges
  node   0: [mem 0x0000000000000000-0x00000001ffffffff]
  node   0: [mem 0x0000000400000000-0x00000005ffffffff]
Initmem setup node 0 [mem 0x0000000000000000-0x00000005ffffffff]

If you want to send me this patch with your S-o-b I'll take it through
my alpha git tree.

Thanks Mike!
Matt

The patch is on its way :)

Now I'm really curios how commit e7793e53901b ("arc: update comment about
HIGHMEM implementation") will work out.

Thanks a bunch, Mike, for the patch and for all you do!

You probably mean fdb7d9b7acd0 ("alpha: remove DISCONTIGMEM and
NUMA"). Works well so far!

Maybe in some alternative universe where I have infinite free time
(and my own power plant!) I'll get a second AlphaServer ES47 with the
enormous "hose" [1] to link the two and I'll poke you for guidance on
restoring NUMA support :)

Thanks again!

Oh, sure, I've copied the wrong line from the log :)

Heh, I'm not sure that restoring NUMA on alpha is really good use for free
time even if it were infinite :)
