<Mahdi>
are the interrupt numbers usually found in the product's documentation? because we will not be able to have access to them in that case
HcE has left #linux-exynos [#linux-exynos]
<javier__>
Mahdi: hi, are you also MahNaz or is another person also wanting to know about the PMU IRQs?
<javier__>
Mahdi: if you also want the IRQ numbers to define the arm-pmu (or if MahNaz is also your nickname), I don't think that PMU works with big.LITTLE yet
<javier__>
since the A7 and A15 cores have different counters so if a task is migrated between different cores, you can't make sense of the data
<Mahdi>
javier__, yes MahNaz my other nickname, Mahdi was taken a few hours ago
<javier__>
or if the b.L switcher is enabled and the virtual CPUs change
<Mahdi>
javier__, I would like to work on that and see if I can find a solution for it
<Mahdi>
in fact, I'd like to focus on the performance counters themselves, not their output values for considering performance or something else
<Mahdi>
javier__, moreover, a patch is written to somehow solve the problems you mentioned. so I guess if I find the IRQs, there might be some chance to solve other problems and verify their correctness
<Mahdi>
javier__, anyway, do you have any idea where those IRQs could be found?
<amitk>
hmm, looks like it got stuck at the review of the first patch about DT :)
<javier__>
amitk: I haven't followed the discussion tbh, I just know that doesn't work because we tried with sjoerd to add the perf counters for exynos5420 before
<javier__>
Mahdi: afaict the PMU IRQs are: for KFC (A7) CPU[0..3] => GIC SPI interrupts 160..163
