Hi all,
I have a question about cache protection. I want to apply parity or
ECC on L1/L2 caches. Should I enable or disable ECC on cache
structures in gem5? Or by default, there is no protection on caches.
Which files should I modify?
By the way, I am using X86 with full system mode.

Hi all,
I encounter the error as following when I simulate ruby_fs.py on x86.
1. scons build/X86/gem5.opt PROTOCOL=MESI_CMP_directory RUBY=True
2. build/X86/gem5.opt configs/example/ruby_fs.py
--disk-image=/home/sanem/full_system_images/disks/linux-x86.img
--kernel=/home/sanem/full_system_i
about these errors?
Thank you in advance for your time and help.
Best Regards,

Hi all,
I have some problems about creating checkpoint. I want to take the
checkpoint from the source code (queens.c). I have added #include
“util/m5/m5op.h” into the source code and I put m5_checkpoint(0,0) and
m5_dumpreset_stats(0,0) statements at the ROI (as shown in gem5 hipeac

Hi,
I want to trace cache data where it is read from or written in caches blocks.
There are several methods in cache_impl.hh file like access,
handleFill and satisfyCpuSideRequest.
In access and handleFill methods, a cache block is written like that:
std::memcpy(blk->data, pkt->getPtr(), blk
Hello All,
I want to inject faults (bit flip model) into the data cache during
the application execution. I plan to generate three random numbers to
select which cache line, which bit of the data within the cache line
and which clock cycle that the fault will be injected. However I do
no
Hi all,
I am using classic memory system and I have added several codes to
the "cache_impl.hh" and "blk.hh" files. However I cannot see the
performance overhead of these added codes on the gem5 execution time.
I have increased cache latency parameters from "CacheConfig.py" file
and I can
that never executes! Can
you confirm that by breakpoints?

Hi All,
I want to build X86 full system with using timing cpu type. There is
no problem in se mode, I can run codes in X86 se mode with timing cpu.
However, I have encountered with problems in fs mode. The command that
I have used is:
/build/X86/gem5.debug configs/example/fs.py --num-
Hi Vinayak,
I have used "busybox sync" command before exiting the simulation to
write all changes to disk.
For example:
./blackscholes 1 /parsec/install/inputs/blackscholes/in_4K.txt
/parsec/install/inputs/blackscholes/prices.txt
echo "Done :D"
busybox sync
/sbin/m5 exit

Hello,
I have a couple of questions regarding McPat. I have a single core
system with two different configuration with/without ECC support on
L1 cache. I run the same workload on two different schemes, however
the power consumption values taken from McPat are interesting.
Values taken fo
any number that comes out of McPat should be considered
dubious at best. There are far more efficient ways to generate
pseudo-random numbers...
