Hello! I'm trying to update a special tracing version of madwifi (driver for Atheros wireless cards) for Linux 2.6.24. This version was created to help reverse engineering the non-free part of the driver (also known as HAL, hardware abstraction layer).
The problem is that functions register_page_fault_notifier() and unregister_page_fault_notifier() are gone in the current kernel git repository. They are needed to intercept access to the card by causing page fault and intercepting it. Those functions were removed on i386 platform because kprobes now registers the flat handler directly. The log says that other callers are supposed to use kprobes now. But what would be the right way to do it? I can intercept do_page_fault() with kprobes, but that looks unsafe, since do_page_fault() is used by kprobes internally. Or maybe I should install a fault handler with register_kprobe()? The problem is, it is only called for faults in kp->pre_handler and kp->post_handler and for single-stepping. I don't want to single-step anything, and moving all driver functionality in kp->pre_handler would be strange. Perhaps I'm missing something obvious. Any help will be appreciated. -- Regards, Pavel Roskin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
