Hi,
I am trying to convert a physical memory location (address 0x000F0000) to virtual memory address in kernel module with pmap_map() / pmap_enter(). Whenever i call these two functions, system hangs. Is this a proper way for conversion?
The same physical address can be accessed from the userspace by opening /dev/mem. The code which does the memory mapping to /dev/mem at kernel level is in ./sys/i386/i386/mem.c as mmrw() which also uses pmap_enter().
kernel = FreeBSD 4.10
