Re: [Crash-utility] DD image
----- Original Message -----
Hi
I had the same problem with CONFIG_SPARSEMEM and if I do not remember
wrong I added:
machdep->max_physmem_bits = _MAX_PHYSMEM_BITS;
machdep->section_size_bits = _SECTION_SIZE_BITS;
to arm.c
and:
#define _SECTION_SIZE_BITS 22
#define _MAX_PHYSMEM_BITS 32
to defs.h in a section for ARM.
I am not certain what these figures stand for but they seems to work
for me.

There seems to be some discussion about future support for SPARSEMEM
on ARM, although like I mentioned before, it doesn't appear to be
in the latest upstream kernel as of yet.
In any case, for it to apply to the crash utility, it should be a
matter of supplying the _MAX_PHYSMEM_BITS and _SECTION_SIZE_BITS
#define's that match the kernel's MAX_PHYSMEM_BITS and SECTION_SIZE_BITS.
And then in arm_init(), they should be initialized as you've shown
above.
