Hi! I have implemented a handler for a IDT entry (exception 1 - trace/breakpoint). This handler shall be called when this exception occurs. However, something is wrong: when I have an application that explicitly sets the flags to trace-mode, this handler is called; when I set up the debug registers with an address (and enable it in dr7), it is not! I suppose that it is because of the address I'm setting up - it must be a «linear address» and I think I'm using just the offset. How can I get the linear addr? Is there a function/macro in kernel? The address I'm using is one that is passed from the process to my kernel module. -- Luís Henriques -- Kernelnewbies: Help each other learn about the Linux kernel.
