Subject: Handling machine check exception
Date: Wed, 11 Oct 2006 21:59:43 -0700 (PDT)	[thread overview]
Message-ID: <20061012045943.9389.qmail@web52403.mail.yahoo.com> (raw)

Hi,

I am trying to modify the machinecheck exception
handler so that checks caused by data access to a
particular address range can be ignored. In mpc866
there is a register called DAR(Data Address Register)
which gives the address[access to] which caused the
exception. However this is not mentioned in the
MPC8247 manual. Is there some equivalent register for
8247. (It seemed to me that the DAR should be a core
register and hence should be there on 8247 also. but
if i try to read i really dont get the address causing
the error).

Or is there some way i can specify that access to a
particular range of address should not cause a machine
check?? Please help.

thanks
ganesh
