[KERNEL][AOSP/TW][27 Dec] War Kernel r3 // colder than ever
- Thread starter GeeckoDev
- Start date
I've been trying to make Nameless HWC work on the Note. It's unsuccessful so far because of an hidden dependency on fimg2d4x (that's why @stelistcristi was getting "runCompositor:stretch failed" errors, and in my case, I get an earlier initialization error). I tried to build the fimg2d4x driver in the kernel to replace fimg2d3x. This newer version is meant to run only on 4x12 devices, but I tried anyway. It compiles fine, and loads fine. Unfortunately the driver is complaining about "invalid params" passed in the ioctl by libfimg.so, so that's where I am.
Then I remembered that fimg2d was used by Skia, the graphics library used by Android, to do hardware acceleration. But... it seems hw acceleration has been removed when rebasing Skia to a newer version for KitKat! It's done by the GPU instead, so that's a performance penalty. fimg2d is currently entirely unused. It would be great if someone could restore 2D HW acceleration :fingers-crossed:
It's still unknown if fimg2d4x can effectively run on Exynos 4210. To do that:
- enable fimg2d4x in the kernel
- build libfimg.so for 4x (there are two different versions in android_hardware_samsung)
- build Skia with SkFimgApi4x and try to run it.
In the generic G2D driver in the mainline kernel supporting both 3x and 4x, the changes seem minimal. 1, 2
Edit: summoning @bauner @arter97
Edit: ok, I did it myself but it's untested. the three old commits were easy to cherry-pick, only a few conflicts. https://github.com/libcg/android_external_skia @bauner

Quite acceptable as a daily driver already
It's never been anywhere near this good!
Thank you guys, for making that happen!
While you two strive for perfection, I'd just like to mention that even with these restrictions the combination of bauner's ROM and Geekodev's kernel is quite wonderful, very stable and quite easy on the battery, at least in relative terms. The 45nm Exynos dual can't hold a candle to these Snapdragons 800s of course, but this combo turns my old backup phone into something quite acceptable as a daily driver next to my Note 3 (also on LP).

Super Happy and Groovy
Happily running DU8.2 with your latest OMNI Kernel and all is well.
Having recently repartitioned the App Volume for 8Gb, I am happily running an untold number of apps without any problems.
Thanks for the awesomeness......................... FabreFaction

Raw Kernel r9 and r5/TW are coming soon, once I get some time with my exams.
I spent the last two days working on my phone but I should have worked my lessons instead.

@bauner built libskia.so with 2D hardware acceleration. Grab it here.
Flash it using:
It seems to break the Play Store app on my phone. Please report.
Edit: doesn't seem to work at all and Play Store doesn't launch because Google Play Services are missing on my phone
Flash it using:
Code:
adb root
adb remount
adb push libskia.so /system/lib
adb rebootEdit: doesn't seem to work at all and Play Store doesn't launch because Google Play Services are missing on my phone

Announcing Raw Kernel r9
#JeSuisCharlie edition
Changes over r8 :
* MMC_CAP_ERASE is disabled, so we can TRIM our device for better I/O performance. The official brickbug patch is merged since at least two years, it's safe.
* -50mV GPU undervolting for group B+ devices
* Compatible with CM12 beta 4
* Added a CM11 variant (a long last!)
Download :
* raw_kernel_r9_omni.zip for Omni 4.4
* raw_kernel_r9_cm12.zip for CM12 beta 4
* raw_kernel_r9_cm11.zip for CM11
Let's talk a bit about TRIM. You should do it once on /system after flashing a ROM, /data and /cache will be trimmed by Android itself. /preload is an unused partition on AOSP, you should wipe it and trim it once and for all. To make the process a lot easier, I created this flashable zip run_fstrim.zip that will trim /system, /cache, /data and /preload from the recovery. I recommend using it just after flashing a ROM (and a TRIM-enabled kernel, of course...), or right now if you have never trimmed before.

I only had one exam yesterday during the events, I was a bit hesitant about going out. It went fine. Today, I didn't go out at all and watched Twitter all day. It's crazy and scary, but I'm proud of how we sorted that out. :good:
@GeeckoDev
I have just flashed NightOwl BETA 4.
Also I have I have performed sdcard0 format from CWM.
Can I now flash yours kernel?
If so can I run this run_fstrim.zip even If I have Insane chip?
BR,

Done both. Still alive.
CPU Governor changed with yours kernel to pegasusq. Leave it that way?

Good job ^^
Tried R9 omni on slimsaber rom and phone is doing great. I even tried the flashable zip for trim i actually don't know if there are any difference on the phone. (sorry if I can't be of any help for that ) btw @GeeckoDev I noticed something but it's not that big, do you remember back on your R7 build there was a post regarding microstutter I'm having that issue. I read back on your post before that you actually asked to push the gralloc for slimsaber will that be the same reason why there's that small lag? but everything is good it's actually not a big problem. will do some testing for the next days to check if there would be any major problems. Again good job and thank you for the hard work! :good:

Hello,
I have just installed, your kernel ( r9 ) on her(it) cm12 beta4 with no problem at all, thank you very much for your work. I have just noticed that the animation of load battery does not work when note is switched off. I do not know if it comes from the kernel or from the Rom, but normally this problem was solved on beta 3, I tilt rather to a problem at the level of the kernel.
What do you think about it? Thank you
bonjour, Je viens d'installer, ton kernel (r9) sur la cm12 beta4 sans problème, merci beaucoup pour ton travail. Je viens de remarquer que l'animation de charge batterie ne fonctionne pas lorsque le note est éteint. Je ne sais pas si cela vient du kernel ou de la rom , mais normalement ce problème a été résolu sur la beta 3 , je penche plutôt vers un problème au niveau du kernel.

@GeeckoDev awesome, only no custom recovery installable. I love the battery endurance of this kernel.
