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

[snow]

The kernel is bootlooping right now. I sent the zImage to paulk from Replicant, so he could test with the UART debugger to see the crash log, but he doesn't have the right resistors to do it. So I will build my own cable as soon as I can.

But I think we need other things from the kernel of ODROID. Somebody already tried to implement new Mali driver, but it seems SurfaceFlinger crashes (maybe SAMSUNG proprietary blobs are not compatible with this new Mali blobs/driver?!)

E/gralloc ( 2001): UMP open failed ump_res 1

This is the interesting bit.

Sorry for noob question, but what that error means? Do you have any clue?

I guess the ump kernel driver is failing, with /dev/ump not being created.

I hope you can fix this.
And share with us any progress about this work

Any progress? Have you checked ump kernel driver?

Just a quick update. I built the UART debug cable, but the guy who sold me the stuff gave me 620 Ohms resistors instead of 620K, so it's not working at all I will return to the shop tomorrow, and I should be able to have it working by Monday evening.

Nice! Thanks for sharing that.

I tried to merge the r4p0 driver alone yesterday, but it seems it introduces changes that break userspace, so I'll try to get that merged to Omni. At least the kernel isn't crashing. Yay, progress! :victory:

I merged mali commits from Nameless ROM, it seems we need a fix something for our 4210 (like you fixed r3p2).

I used:

- Gustavo kernel [https://github.com/gustavoss/android_kernel_samsung_smdk4412, master branch] (for i9100 device) which already has https://gerrit.nameless-rom.org/#/c/8950/ merged (https://github.com/gustavoss/androi...mmit/57bcd58c80806fb564709d8345bcca0ff45110c4)

- merged https://gerrit.nameless-rom.org/9081;

- modified defconfig
CONFIG_MALI_VER_R3P2=y ---> CONFIG_MALI_VER_R4P0=y
# CONFIG_PM_DEVFREQ is not set ---> CONFIG_PM_DEVFREQ=y

After doing this, building and flashing, copying blobs on the phone, screen is black. And I was able to get a logcat. Maybe is useful for you! HERE: http://pastebin.com/UAvtZCS7

I'm just trying to help.

Hello guys

The OP says it's only for Omni Rom. But as far I've tested, it worked fine, in fact better on Slimsaber & Latest SOKP.
Though, best option is to make a nandroid backup fefore flashing with any ROM
