I'm sorry if I am mistaken. The "DP driver" would seem to refer to the linux software driver you are proposing patches for, however this diagram looks like a hardware diagram of the various hardware blocks that the Linux driver code (the "DP driver") is expected to interact with. I believe you should re-word "The block diagram of DP driver is shown below:" to be more specific of what you are describing with your figure. IE your words say this is a block diagram of the software, when it looks like it is a block diagram of the hardware. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
