The value of this event has changed # over time: # # - Power7 uses 0x400f0 # - Power8 and Power9 use both 0x400f0 and 0x3e054 # - Power10 uses only 0x3e054 # # Rather than relying on raw values, configure perf to count L1D read # misses in the most explicit way available. # # This fixes the selftests to work on systems without 0x400f0 as # PM_LD_MISS_L1, and should change no behaviour for systems that the tests # already worked on. # # The only potential downside is that referring to a specific perf event # requires PMU support implemented in the kernel for that platform. # # Signed-off-by: Russell Currey # Acked-by: Daniel Axtens #
