vectors usually get activated prior to return from the set affinity function, but on some apics, the hardware IIRC requires occasional deferral until various hardware conditions are met, check me...
You'll have to dig into the kernel code to find that
what are the interrupt counts like on those newly registered interrupts? irqblance estimates the load on the cpu of the cumulative number of interrupts affined to each core. If the...
I'm sorry, I'm not being clear - when I say what are the interrupt counts like, I'm asking how many times have those interrupts been asserted, and how much cpu...
What I'm looking for is the number of time each specific irq was triggered. The output of /proc/interrupts should provide that
Thank you. I assume its your network card, driven by the ice driver thats in question here? If you look at the proc/interrupts file, for any irq that part of...
Woo hoo! Well done!
I've been trying to ignore any possible performance issues while this is in draft, just to make sure that the new api functionally works. Once it all works, I think...
I did some quick measurements on this approach, and came up with the following: Methodology: Using our perftools repo, I repurposed one of our tests to run the CRYPTO_THREAD_set_local /...
Fixed up my stats collection to get better results. Using two sparse arrays produces this comparison:  And replacing the top level sparse array with a fixed size array, allocated...
