Message-ID: <20110608131634.GA13434@mailer.i88.de> Date: Wed, 8 Jun 2011 15:16:34 +0200 From: "Micha M." <linux-kernel@...l.i88.de> To: linux-kernel@...r.kernel.org Subject: Calling code Hi! I'd like to know if it is possible to jump to a certain address, run code from there and then return to the kernel-module (the caller). That code is located somewhere in the physical address space and uses (internal) also physical addesses. I tried to ioremap that function, but unfortunatly I got some page faults causing an Oops. I realized that this approach will not work regarding the fixed and absolute addresses in the code. So is there a way to jump to a certain address, run code from there and after execution return to the caller? I would prefere a way without assembly :-) Regards, #micha -- /* To err is human; to really fuck things up requires the root password */ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
