Hi Andreas,
I am running map and office applications on a modified disk image.
I only modify the cache policy of gem5. The version of Linux kernel is
2.6.35 and I just modify the size of vncview.
It is difficult to reproduce the panic. The panic may no longer
exist when I rerun the simulator using the same configuration.
Thanks.
Best regards,
Yongbing Huang

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
