Re: PS3 early lock-up

quoted

ps3_hpte_insert() seems to be called during system initialization with the
following values of rflags:
  - first call: 0x190
  - initial memory: 0x194 (455 times)
  - hotplug memory:
      o crash: 0x115
      o OK: 0x117

Do you have an idea of what's really going on?

Weird... Both look incorrect. In fact, it's a bit scary...

The one with the 7 at the end means that user space as RO access to
the segment (oops !) and supervisor too. The one with the 5 means
RO for user and RW for supervisor.

That is unless your HV is munging them in strange ways... I don't
know why LV1 is refusing a combination though.

As for the flags, it depends what htab_bolt_mapping() is called
with.

Do you have a backtrace ? I'm a bit lots in the mem hotswap code
trying to figure out where the mapping comes from..

Ah, found it... It should be ok... both the mapping of the RAM itself
and vmemmap_populate() should be passing 

  _PAGE_ACCESSED | _PAGE_DIRTY | _PAGE_COHERENT | PP_RWXX;

Which should be 0x194.

Can you find out where that stupid value comes from ?

Ben.
