Hi There, I am looking for a way  to block a SATA drive from being recognized by SCSI subsystem. Is there any way to block between libata and scsi subsystem? I don't want to modify libata, but looking for a way through loading a module. Thanks Irfan_

Harishkumar, I already know my SoC name, it is Celestial CSM1203, and it is not available in any official kernel source tree ( the last one I checked it 3.4.1 10 minutes ago). Since it is not available in the original kernel source, we had to make those thousands of changes one-by-one, and it

Dear Harishkumar; I already know how to find the changes, please see my 1st e-mail below. The problem is, those changes are more than thousands of lines of code, and hundreds of files are added or modified. I wonder, how can I apply those thousands of changes to new kernel source quickly and e

Sertac, Also, if u know ur chip SoC name, u can find whether open source linux kernel may have already support inbuilt in it. u can google around it, before deciding to port. On Thu, Jun 7, 2012 at 5:18 PM, Harishkumar V wrote: > Sertac, > > From your present source, u can find the Celestial SoC

Sertac, Basically u need to have Celestial SoC & drivers related patch. Then, u can download desired kernel or latest 3.3.x. Apply and do the forward porting. It won't be straight forward, u need to re-write a bit. U can always refer any other celectial SoC family in latest kernel source or other
