The kernel parses parameters from the kernel command line up to “–”; if it doesn’t recognize a parameter and it doesn’t contain a ‘.’, the parameter gets passed to init: parameters with ‘=’ go into init’s environment, others are passed as command line arguments to init. This is handy if debugging and you need to use tracing_snapshot() on boot up, and do not want to use tracing_snapshot_alloc() as it needs to be done where GFP_KERNEL allocations are allowed.
Everything after “–” is passed as an argument to init. DRM Direct Rendering Management support is enabled. amd_iommu= [HW, X86-64] Pass parameters to the AMD IOMMU driver in the system.
