Huh? 5410 only has the *A15* cluster described (and for whatever reason mainline cannot bring up the A7 cluster even if you do add it). Also*, the interrupt affinity properties are bogus as presented - those will need to be delegated to the SoC-variant-specific dtsi files in the same manner as the "cpus" nodes, to cope with the different CPU numberings. Robin. *I'd like to have made this comment inline in the patch, but I can't :( > Tested with perf on Odroid XU4 (Exynos5422): > armv7_cortex_a7 PMU driver: 5 counters available > armv7_cortex_a15 PMU driver: 7 counters available > > Regards, > Marian > > -- > Either I've been missing something or nothing has been going on.
