how to view kernel memory map?
Yo! yo! 'sup my dawgs?
I'm trying my hand at a bit of kernel hacking/debugging and - forgive my n00bishness - is there a way to view the kernel's memory map and see what driver a particular area of memory is allocated to?
Two of my 8250 serial ports don't work. During initialisation the driver calls request_mem_region() to try and grab 32 bytes at 0xd0103000 and 0xd010b000. These calls fail and return -EBUSY.
System.map doesn't go this high in memory (_end is at 0xc0a0e000).
How can I find out what is interfering with my serial driver? Does anyone have any suggestion on how I might fix this?
