[gem5-users] panic: Uncachable load

[huangyongbing]

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
