[gem5-users] snoop filter exceeded capacity of 131072 cache blocks

[Gongjin Sun]

Hi,

I'm running a single thread SPEC CPU2006 benchmark (410.bwaves) on the
latest Gem5 version with a generated checkpoint (at 1000000th
instructions). Unfortunately, I encountered the error as the title says:

panic: panic condition !is_hit && (cachedLocations.size() >= maxEntryCount)
occurred: snoop filter exceeded capacity of 131072 cache blocks
