Hi all,
While booting MVL linux
Have you talked to MV support? For community support, it's best to use
the latest upstream sources (and arch/powerpc, not arch/ppc).
BTW, it's generally bad form to post the same question repeatedly. If
you have new information regarding your problem, just post a followup in
the same thread containing the new information.
arch/ppc/kernel/setup.c
----------------------------------------
unsigned long
early_init(int r3, int r4, int r5)
{
unsigned long phys;
unsigned long offset = reloc_offset();
/* Default */
phys = offset + KERNELBASE;
/* First zero the BSS -- use memset, some arches don't have
* caches on yet */
memset_io(PTRRELOC(&__bss_start), 0, _end - __bss_start);
__bss_start is 0xc039b00 and __bss_stop = _end =c03c7d90 _end
Please anyone give me some pointers to understand this i.e use of
PTRRELOC
The kernel hasn't been remapped yet, so the pointer is adjusted manually.
and REASON BEHIND clearing area from __bss_start to _end - __bss_start even
though lot of
symbols and functions are defined here(as per System.map)
That's what the BSS is for -- symbols that are cleared at runtime so as
to eliminate the need to store them in the image. There should be no
functions in there.
