Hi, I have a nvram module in my system. I am able to detect the nvram memory address via the bios_smap. Now I want to be able to access this nvram memory for operations like memcpy(). What do I need to do for able to access this nvram memory?
I went over the hammer_time() function defined in sys/amd64/amd64/machdep.c file. Here we call the getmemsize() function where we create the phys_avail[] array and call the PHYS_TO_DMAP to map the message buffers. Finally we call msgbufinit() function. Is anything more needed to be done for physical memory to be accessed? -- Sourish Mazumder _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-amd64 To unsubscribe, send any mail to "[email protected]"
