Rao <naveen.n.rao@linux.vnet.ibm.com> # Date: Tue Oct 23 13:34:56 2018 +0530 # # 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. # # Reported-by: Joel Stanley <joel@jms.id.au> # Signed-off-by: Naveen N.
