Re: Documentation for usbmouse.c
Valdis, for quite some time now you have been attaching a 'noname' attachment to all your replies. Is this intentional? If it isn't I kindly ask you to resolve the issue :) Sorry for the offtopic response.

Linux and interrupts. How do they work?
My question pertains interrupts in SoCs, smartphones etc. I am examining some drivers and the code for the architecture in arch/ and I see code that defines a struct resource with .start and .end members that are the same, with .flags = IORESOURCE_IRQ. Where .start and .end is some value like 0x234, my question is if this is an address of the phone's memory(RAM) or is it something else? I am simply trying to figure out how various hardware issue interrupts, is 0x234 a memory address or a value that the CPU sees somehow(but from, where?) and tries to find a handler for this specific interrupt. My specific issue here is that I have a SoC that has an ARM cpu that runs the Linux kernel and everything else, but the SoC also has another chip that has a separate embedded arm CPU inside it running some ARM code, which when it has some work to send it issues an interrupt. And I am simply trying to understand how that works. I apologize if my question is too generic and does not pertain to Linux at all. Thank you. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
