Hello -

 

I'm currently porting vmlinux from NEC's EMMA2L platform to EMMA2.  The
problem I'm having is that linux hangs when it attempts to do its first page
fault: the page fault handler is successfully called, the call to
handle_mm_fault returns 2 (major fault).but then code execution appears to
just stop.  Linux is not completely dead, however - it still responds to a
timer interrupt.

 

As the code for handling page faults is standard code, and TLB hardware
should be the same on EMMA2 as on EMMA2L (where it works!), I don't
understand what's gone wrong!  Does anyone have any ideas?

 

Thanks for your help,

 

 

Gill
