My name is Yoshihiro Furudera.
I am developing a libpfm4 library at Fujitsu.

The following events are not counted properly:

0x0037 LL_CACHE_MISS_RD
0x400B L3D_CACHE_LMISS_RD
0x0396 L2D_CACHE_REFILL_L3D_MISS
0x039A L2D_CACHE_REFILL_L3D_MISS_PRF
0x039B L2D_CACHE_REFILL_L3D_MISS_HWPRF
0x039C L2D_CACHE_REFILL_L3D_HIT
0x03A0 L2D_CACHE_REFILL_L3D_HIT_PRF
0x03A1 L2D_CACHE_REFILL_L3D_HIT_HWPRF

Specifically, these events are always counted as misses,
regardless of whether the L3 prefetch is a hit or a miss.
So I remove these events in arm_fujitsu_monaka_events.h

Please review and merge these patches

Best regards.
Yoshihiro Furudera

    I'm sorry, but we withdraw this merge request for the time being as we are reconsidering our approach.
