[gem5-users] Strange: Cache data not maintained in gem5

[Muhammad Avais]

Dear All,

I was tracking zero blocks (64B 0 value) written to cache.
During experiments, i found that cache block does not hold data sometimes.
To some cache lines non-zero block is written to cache line from lower
level memory but this data is read as Zero block during access by upper
level cache.

I could not find how this data is changed ?

Many Thanks,
Best Regards,
Avais
