[KERNEL][AOSP/TW][27 Dec] War Kernel r3 // colder than ever

[Macrint]

Is there any chance of having an OC version of GPU (160-267-400)? Or maybe something like forest's (includes OC CPU&GPU) but with r3p1 + 60/62/64hz features for TW in the near future?

It has been asked before and the answer was that we might see such a kernel once all other ways of improving performance have been exhausted. You're not the only one hoping for it.

Kind regards

Have you ever used and read the announce links in first post?

There are no announce links saying that. Btw took one much to beat around the bush; forcing use gpu in 2d seems to fix these bro. Youtube fc as well.

Keep posting.

Geecko, any plans for that sweet news about the hwcomposer?

Geecko, any plans for that sweet news about the hwcomposer?

* Wait for it to be running well on 4412
* Get my desktop pc back
* Port it to 4210
* Enjoy the **** out of it and never go back to Touchwiz again.

But its only for i9300

 

[drulo222]

That must be a reason why phone os are complicated to port over to hundred of phones, because its tailored to the hardware, while on pc any hardware is almost compatible with a new os install. Thats what hwc seems to be, a blueprint of some sorts.

@GeeckoDev notice you that on Raw R3 TW on recovery, memorys are inverted (select internal sd goes to MicroSD viceversa select external_SD goes to eMMC).
Anyway great job man thanks for all

I got Mali r4p0 drivers running on my second phone, on Omni.

It took so long because I had not figured out that the blobs had changed paths for "/dev/ump" and "/dev/mali", using "/dev/ion" and "/dev/mali0" instead. Our gralloc is still searching for the old paths, so I had to hexedit the blobs to change them. Logged errors were not very clear about this...

I'm quite disappointed about the results though. I was expecting a miracle but it isn't at all. Here is what I observed so far:
- Performance dropped from 46fps (r3p2) to 37fps (r4p0) on Epic Citadel.
- SystemUI is crashing at boot and the launcher gets very slow. Other apps seem to work fine, so it's weird.
- In Epic Citadel I observed a few graphical glitches I never saw before.

Not worth it.

Thanks for your efforts Geecko
Good job!

We are waiting also CM12 kernels.:thumbup:

Running last version of your tw r3 with fantastic performance!

Are you still experimenting on future improvements? Maybe undervolt optimization, or a 64hz version?

I don't have plans to improve the TW kernel much, but I'll be working back on the AOSP side very soon.

Yes, maybe get the boot animation fixed + some more ggodies Thanks for your efforts!

Looks like they've begun work:

So their magical solution is to run the proprietary hwc?

From my observations hwcomposer is not the problem, gralloc is.

I've set up a gralloc-mali repo to see the differences between each release of the open-source gralloc module provided by ARM (these f***ers never provide a changelog). It seems that our current gralloc is based on the r2p3-01rel0 release with some Exynos-specific changes (and hacks) on top. I would love to start working on that but I need my desktop PC first.

I've realized that each Mali release (blobs + kernel source + gralloc) is targeted for a specific version of Android:
r2p3 -> ICS (makes sense since our gralloc is based off Insignal release for ICS)
r2p4/r3p0 -> JB 4.1 (Samsung uses r2p4 on JB 4.1 for performance reasons)
r3p1 -> JB 4.2
r3p2 -> JB 4.3
r4p0/r4p1 -> KitKat (Samsung uses r3p2 on KitKat maybe for performance reasons too)
r5p0 -> Lollipop (we have yet to see this release on an Exynos 4 device, will probably never happen)

@GeeckoDev

Can't we use their (r4p0) blobs and gralloc for our note? Same CPU tree and same GPU.

I tested r4p0 recently, it's not very good, I had a lot of issues and reduced performance. Maybe I did something wrong though, but I have no idea what could be the cause.

Edit: *quack*

Announcing Raw Kernel r7

Time for a new release.

Changelog :
* Latest Omni changes included
* Restore stock GPU steps, thresholds and voltage (2 steps: 160/267MHz instead of 134/200/267)
* 59hz panel refresh rate instead of 57hz
* gralloc with refresh rate drift fix included

These three changes should bring another increase in smoothness and responsiveness. Do not expect Touchwiz smoothness though, we still need to fix userspace :laugh:

Download :
* raw_kernel_r7_k44.zip
* raw_kernel_r7_l50_alpha.zip <- This is an early Christmas present for those few people who run Lollipop. It even has a semi-working recovery from Omni.

Dear GeeckoDev, thank you so much for your kernel!!!!
I now have the perfect combination to make my note fast, battery friendly and reliable with much comfort and security.
Things I am using and that I can recommend:
* Your kernel (for undervolting, faster graphics)
* SlimSaber KK 4.4 ROM (fast and comfortable with many options)
* XPosed-Framework (with XPrivacy, AppSettings)
* LLama + SecureSettings (for saving battery e.g. turning off Wifi/GPS when on battery and screen goes off, turning on bluetooth when in Car mode, ...)
* Larger (6GB) /data Partition (repartitioned with .pit file)
* Greenify to hibernate all the apps not in use
* Titanium Backup for freezing system apps I do not use
* AdBlock (for faster browsing without apps)
* FolderMount for moving some folders to ExtSdCard
* From time to time I flash lanchon kernel and use recovery trimmer to do TRIM (makes nand memory faster), then back to your kernel

I am over the moon and very amazed that my "old" Note 1 is so fast and well-useable. Hope I can use it for some more years to come. Congrats and thanks to every developer who made this possible.
