Just imagine if the person does not knows the file name or variable name then how will he get it. That is what I mentioned.I finally think that I got solution for it. Just go the concerned option and press a question mark over it. It will show you in background the variable associated with it. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Re: what is the kernel symbol for user space grant access driver
I'm not sure if I got your point, but I guess you want to make sure that code activated by your configuration option is included into the kernel image. Let me illustrate that by example: PC parallel port. (Device Drivers-> Parallel Port -> PC-style hardware). This option is associated with CONFIG_PARPORT_PC configuration option. This option includes the following source file drivers/parport/parport_pc.c. Looking at this file you will see that it exports parport_pc_probe_port method. We can run the following command to see if it was included into the kernel image: nm vmlinux | grep parport_pc_unregister_port and you will get: 8187b5fe r __kstrtab_parport_pc_unregister_port 81860080 r __ksymtab_parport_pc_unregister_port 81283b58 T parport_pc_unregister_port when we turn off this option for the command nm vmlinux | grep parport_pc_unregister_port is null Regards Tomasz Bartczak Mozesz kupic dom juz nawet za 120 tys. zl Sprawdz >> http://linkint.pl/f2937 ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Compile the kernel with and without that option enabled than diff the .configs. thanks, Daniel. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
