hard coded value for idcode field in struct cpu_table
Dear All, I do not understand the value of idcode field in the struct cpu_table i.e. the value is hard coded. I did not find that value in the user manuals, also. The code is available at linux/arch/arm/plat-s3c24xx/cpu.c file. Currently, I am trying to implement the code for Samsung S3C2510A processor which is not available in the current sources. Where can I find the idcode value for Samsung S3C2510A processor? Any ideas will be appreciated. Thanks and Regards, Madhavi M. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Re: Network Drivers Master Slave
Hi, Have a look at bonding driver. This might help. Best Regards, Alice 2011/3/4 sugnan prabhu sugnan.pra...@gmail.com: Hello All, I have written two network drivers master0 and slave0, where the packets received by master0 interface will be forwarded to the slave0 interface and vice versa. I have further linked the master0 interface to a usb driver in such way that, interface registered only on connecting the usb device. My requirement is that, when ever the master interface is up, slave interface should be brought up automatically and when the master device is disconnected then even the slave interface should be disconnected, so that the slave interface drops the data. Can some one give some pointer for doing this in a right way. I have been trying to understand the pernet device framework, can someone please explain it briefly.

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

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

Sorry... Actually I think you did a great job, at least you provide a tool for newbies like me to have a chance to learn file system. What is the difference between real partition and image? for kernel, they are nothing but a place to write file systems, right?
