As far as i could understand, LPI is added to a collection as a part of setup. And collection actually represents a destination CPU, doesn't it? And we can't have multiple LPIs sharing the same number and going to different CPUs. Or am i wrong? Unfortunately i don't have GICv3 arch reference manual. > Another concern > would be the support of GICv4, which relies on the command queue > handling to be handled in the kernel Wow, i didn't know about GICv4.
