Hi All: I am writing user space application and need to allocate a continuous memory. The size is just 64KB and I also need to know the allocated physical memory address. Is is possible to do it in user space or it should be done it kernel space? BTW, how to allocate continuous physical memory and got it physical address in kernel space? In addition, is there any different between to trigger a SMI (System Management Interrupt) in user space and kernel space? I appreciated if someone give me a point. BRs, H.
