I have installed the precompiled downloaded image from PARSEC website. When
I run the following configuration, the benchmark runs to completion for all
three versions of the benchmark - small, medium and large. But when I try to
run the same with prefetcher I am geeting the following error and the
simulator aborts.
I have made the following changes in the given files
Added the following line in CacheConfig.py
system.l2.prefecth_policy = 'tagged'
I have made chnages in some parameters of file BaseCache.py
prefetch_on_access True
prefetch_past_page True
prefetch_serial_squash True
prefecth_policy 'tagged'
prefetch_data_accesses_only True
I recompiled M5 and run it to get the following error
build/ALPHA_FS/m5.opt configs/example/fs.py -n 4
