Subject: malta 4kc and tlb-r4k.c
Date: Thu, 17 Jan 2002 13:58:33 -0800 [thread overview]
Message-ID: <3C474909.4DF82E72@mvista.com> (raw)
I needed to add a BARRIER between :
set_entryhi(KSEG0+idx*0x2000); and
tlb_write_indexed();
in local_flush_tlb_range() (tlb-r4k.c), otherwise I get a bootup
failure:
Kernel panic: Caught Machine Check exception - probably caused by
multiple matching entries in the TLB.
Malta 5kc didn't have this problem.
Also, the call
set_entryhi(KSEG0);
doesn't seem necessary.
