[Kernel] Stock Overclocked to 1890MHz and init.d support - Testing only - Fire TV Android Development

based on Stock kernel amazon 514006420 sources with just the following 2 features added:
Overclocked to 1890MHz
init.d support (place files in /etc/init.d/ folder)
Since there is no known way to get into recovery with a bad kernel (yet), therefore it flashes only to the recovery partition for your safety. When you are done testing flash rbox's recovery back to the recovery partition.
prerequisites:
rbox's unlocked bootloader
rbox's latest recovery
instructions:
in CWM - flash zip
advance -> reboot recovery
When you boot into recovery the new kernel will boot, when you boot normally your stock kernel will boot. You will not have recovery until you flash rbox's recovery again.
Flash at your own risk!

Curious, what are the benefits of overclocking the Fire TV?

Well it is called FIRE tv... so you can hope it lives up to it's name and catch on fire... Of course it's partly joking...

The FireTV has a MASSIVE heatsink.
What about the Adreno GPU?
Can you overclock Adreno320 from 400MHz to 450MHz or 500MHz?

That's a good idea, i'll look into it when i have some spare time.

Can you notice any performance increase?

---

Here is an old topic I made which has a directory I found that contains the Adreno clocking files...

I don't really use it that much and it wasn't slow before, so not really but here are my antutu benchmarks with GPU OC to 450, post yours and we can compare:

Thanks, i got it up to 450, but i'm going to see if i can get it any higher.

Can you try out Mupen64Plus AE with those overclocked rates?
You can get a nice dev build in this thread to test (I also have it) that fixes DK64 collisions and stops Banjo-Tooie from crashing.
http://www.paulscode.com/forum/index.php?topic=1797.0
Try running Banjo-Tooie with my "no frameskip" code.
There is now a cheat editor built-in on this dev update,so you can easily add it to the cheat list.
No Frameskip
8007913F 0001
It normally lags quite a bit for me,please tell me how well it runs for you with overclocked CPU and GPU rates.

@jmandawg Hi, If it possible for you to enable the kernel exec (kexec) to allow us run linux kernel and I did asked @rbox to add the kexec support for CMW recovery. I think the kernel with kexec enable so it will allow cmw recovery with kexec enable boot linux kernel. rbox still figure how do it. I couldn't risk overwrite recovery partition with linux kernel due the kernel itself tend over 20mb which is the recovery partition only has 10mb space.
Otherwise I tested benchmark on my AFTV got 29301 score (stock) and am going test this overclock kernel to see how much improvement.
thanks again...
*UPDATED* I ran your overclock kernel, It apparently that benchmark went decreased to 26414 score vs amazon stock 29301. I puzzled. Something is going wrong. Maybe I should reset factory and reinstall fresh rbox's pre-rooted then re-test benchmark stock rbox pre-rooted vs overclock kernel again.

There's a pre built fedora kernel that works already in the fedora thread.. No need for kexec or unlocking either..

---

@nhumber Does pre-built fedora kernel size byte under 10mb? Let me read fedora thread again. thank you letting me know.

No you'll have to do some playing with partitions, diag partition is what I tested, renamed to recovery.

can you try running 3dmark benchmark with the modded kernel and gpu clock? might give a good indication on if theres any real world performance gains for gaming, i dont game on my firetv at all but i ran the benchmark just to watch and get a "stock" score for comparison, i scored 10958 on icestorm unlimited, i took a screenshot with the FPS of the different tests i can upload later, my galaxy s4 scored 10650 but i noticed google play was downloading stuff in the background..

Question: I get the fact that having an OC kernel is cool, but is it really needed? This thing runs very smooth, and I'm unsure if the extra load on the CPU is worth it... Even the potential shorter life to the CPU.
Also I don't know how efficient the thermal pad ( uses a pad not paste ) is under normal circumstances let alone when its going to be OC'd.

its probably not needed, i agree with the device being fast enough already, i dont play games on it, but for someone who does there could be some improvements noticed in things like emulators where you might already be seeing FPS drop here and there. 1.9ghz is the stock clock speed for these CPUs in some smartphones so i doubt its doing the hardware any damage at all.

Fire TV really does have a massive heatsink,which should help greatly when CPU and GPU are overclocked.

---

I'm talking about the heat... Sure it has a nice heatsink, but it can and will heat soak sooner or later...

---

Have you seen the aftv internal? They got darn excellent heat sink fully aluminum enough handling the heat soak absorb.
I have tested clocking over clock CPU and surprised that the heat is normal range yet hit overheat!
However I tested the benchmark yet beat the pre-rooted stock benchmark. We still tweaking like we still in baby mode
