Analysing a couple of architecture’s IRQ subsystem implementations reveals that most of … WebParameters for modules which are built into the kernel need to be specified on the kernel command line. modprobe looks through the kernel command line (/proc/cmdline) and collects module parameters when it loads a module, so the kernel command line can be used for loadable modules too.

WebJun 22, 2024 · To mitigate this I suggest tuned to set the 'irqaffinity=' kernel command-line option to match the non-isolated CPU mask when running the realtime-virtual-guest config. This way we'll get the right affinity regardless of the situation stated above. This affects rhel8 too. But nobody complained so far (the latency spike wasn't big enough I guess). WebIRQs have an associated "affinity" property, smp_affinity, which defines the CPU cores that are allowed to execute the ISR for that IRQ. This property can be used to improve …
