Fast path operations are typically performed by writing + directly to hardware registers mmap()ed into userspace, with no + system call or context switch into the kernel. + + Commands are sent to the kernel via write()s on these device files. + The ABI is defined in drivers/infiniband/include/ib_user_verbs.h. + The structs for commands that require a response from the kernel + contain a 64-bit field used to pass a pointer to an output buffer. + Status is returned to userspace as the return value of the write() + system call. + +Resource management + + Since creation and destruction of all IB resources is done by + commands passed through a file descriptor, the kernel can keep track + of which resources are attached to a given userspace context.
