DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hello all.

I first have to apologize if this has been answered elsewhere... I've searched and searched and have pieced together bits and pieces but have some specific questions regarding building and installing a customer kernel for a debian wheezy install (DNS-323 rev B1)

I've managed to get the system installed, and the main use will be to use as a Plex Media server to stream to an ATV3.  I've got all this working (believe it or not the Synology package downloadable from the plex site works, just unpack and run the start.sh script  - with a couple of mods to LANG="C" parts of the script... then run the PlexConnect package) but wanted to try and increase performance just a little. While trying to find some tweaks to increase swap performance, I stumbled onto a kernel feature called ZRAM... which looks promising in terms of virtually increasing the amount of RAM (via compressed swap in RAM)...

So, I cross compiled for ARM on a different system... No issues there.  I'm in the process of doing a "make uImage"...

The question is, what are the next steps.  I know I need to do a mkinitramfs (are there specifics somewhere in terms of how to ensure that boot-time modules are included in the image: md, lvm, sata, etc...). Also, once uImage is complete, and the initrd are complete, how do I install the kernel?  Are there any further steps required other than just a dd if=uImage of=/dev/mtdblock2, and dd if=initramfs of=/dev/mtdblock3?

During the build, does the kernel need any special patches to make it work with the Marvel uboot loader?

Is there a write up somewhere I can reference in terms of a how-to for custom kernel build and install?

Thanks in advance.

Ben
