Re: [gem5-users] panic: Uncachable load

[Andreas Hansson]

Hi Yongbing,

Could you elaborate a bit on what you are running? For example, is this on an 
unmodified trunk? If so, how to reproduce it?

Thanks,

Andreas

Subject: [gem5-users] panic: Uncachable load

Hi all,

         I run the simulator using the arm_detailed CPU model while simulating 
the ARM platform. However, the bellowing panic will occur sometimes:

panic: Uncachable load [sn:4af0382b] PC (0xc016b5c0=>0xc016b5c4).(0=>1)         
 (PC is different for different times, but PCs are often like 0xc016b5xx)
@ cycle 611133741299620
[invoke:build/ARM/arch/generic/debugfaults.hh, line 94]

         The source codes of above panic are contained in the file 
cpu/o3/lsq_unit.hh:
                   LSQUnit::read()
                   {
             if (req->isUncacheable() && (load_idx != loadHead || 
!load_inst->isAtCommit())) {
                                     …
                                     Panic(…);
                   }
         }

The pc shows this is the instruction of Linux kernel. So are they any ideas 
about the reason?

Thanks.

Best regards,

Yongbing Huang
