The standard trick to do that is to copy the module binary to four different names (the module name is not encoded in the binary) But it would be better to just fix the driver to allow this with a single instance with some other run time configuration mechanism and not use module parameters (which are generally somewhat deprecated anyways) -Andi - 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/
Re: Problem: one driver and 4 instances with different parameters
I think you need to modify your driver. So that you need to do only single insmod. and handle the 4 instances internally.

Problem: one driver and 4 instances with different parameters
Hi, Could someone to make clear next question: I have one driver, but I need to run 4 instances of it (I run insmod with different parameters) . But when I try to install the second driver I've got an error, that driver with this name exists. How can I istall them? I don't want to use 4 different driver's sources.
