#     selftests/powerpc: Relax L1d miss targets for rfi_flush test
#     
#     When running the rfi_flush test, if the system is loaded, we see two
#     issues:
#     1. The L1d misses when rfi_flush is disabled increase significantly due
#     to other workloads interfering with the cache.
#     2. The L1d misses when rfi_flush is enabled sometimes goes slightly
#     below the expected number of misses.
#     
#     To address these, let's relax the expected number of L1d misses:
#     1. When rfi_flush is disabled, we allow upto half the expected number of
#     the misses for when rfi_flush is enabled.
#     2. When rfi_flush is enabled, we allow ~1% lower number of cache misses.
