AOSP Kernels for HTC's 8x50, 7x30, and 8x60 Devices
Also available for the Motorola Xoom

Quote:

Tiamat kernels are designed for use on all ROMs that are built from the AOSP source code. This includes ROMs built from MIUI, CyanogenMod, and others.
Tiamat receives no support for use with ROMs based on HTC's Sense - use at your own risk.

You can find full details about Tiamat Kernels at our website. The site is up and running and serves as a more centralized location to get updates, downloads, and changelogs for all Tiamat Kernels. There is no forum or Registration, it’s just a more convenient way to keep things organized as we work to add support for more devices.

Downloading this now to try out; I assume that you included both Evervolv's and r2doesInc's GB ROMs in your statement of "all current GB ROMs"? That'd be great, because I swear that Invisiblek's kernel, fast and fluid as it is, is causing some majorly excessive overheating in my phone. I'd prefer that my phone break down...well, never, but if it did, closer to my contract upgrade date. lol hoping yours puts out less heat (and I'm only running the main profile at 1.1GHz, so it's not even that much over the stock).

Question: What exactly is HAVS and what is this undervolted to? And I don't know how to test USB tethering, sorry. Also I am running Cyanogen 6.1

I have installed this and ran a quadrant score and linpack test that I will post a screenshot of. I overclocked to 1.15 w/ smartass governor as default:

So far no problems with the kernel.

Does your kernel offer any built in screen off profiles when using the Smartass governor? Some kernels with smartass usually do a min-max screen off profile of 245.

Just checking, in case I have to make a screen off profile in setcpu.

Second this, i'd like to know about all of this too.

Screen off on smartass sets to 128/384 min/max.

I have installed this and ran a quadrant score and linpack test that I will post a screenshot of. I overclocked to 1.15 w/ smartass governor as default:

I've seen quadrant scores in the mid 1500's with this kernel. The linpack app always gives kind of low scores since it was updated. With 0xBench, I've seen linpack scores in the 41's.

HAVS is hybrid active voltage scheduling. It allows the CPU to dynamically change the voltage at each frequency (speed) based on need. The ultimate result is better battery life.

This kernel will undervolt as far as 925 mV at lower frequencies. That is a fairly aggressive level and honestly, it may need to be raised a bit. On the other hand, I'm coming from the Evo which is a bit more power hungry (a lot of Evo's can't boot with that low of an undervolt, but my Incredible has not had any issues with it).
