Greetings! I am trying to work on GNUmach 1.3 drivers (not using oskit).
I don't want to use the linux drivers with glue interface as I want to build my own subsystem in the kernel with driver support, atleast want to learn how to do that. I have written a small C file with two functions, and added it to kern/ directory in gnumach/, and modified the Makefile.in so that the code compiles with the kernel. I did an objdump on the created gnumach image and found the disassembly of the two functions :). 1. I can simply call the above two functions from one of the kern/ C files to test if it gets called. When it comes to a device driver interface, and assuming the above are two driver functions, where do I register this driver such that the kernel will call this particular function? 2. How do I write a user-space function that can open this particular driver in gnumach to demonstrate the control flow between user-space and kernel-space and vice-versa. I am totally blank on this part :( I have seen include/device/device.defs having the device driver interface. But, I have no clue as to how to go about it. I'd appreciate any simple hello-world driver example to get me started on this. Looking forward to some code examples, K Shakthi ------------------------------------------------------------ Shakthi Kannan, MS Software Engineer, Specsoft (Hexaware Technologies) [E]: [EMAIL PROTECTED] [M]: (91) 98407-87007 [W]: http://www.shakthimaan.com [L]: Chennai, India ------------------------------------------------------------ __________________________________________________ Do You Yahoo!?
