Hi,
I'm trying to upgrade Mali driver on my I9220.
Linux kernel : 3.0.31
Processor : exynos4210
Target Mali driver version: r3p1
I only replaced Mali driver in the kernel .
And I could get linux kernel image successfully. (Mali driver is built -in form.)
I turned on my board and saw all black screen.
I also checked memory address in config.h file.
I only saw booting screen then the screen was changed in black..
is there any other driver should I replace? such as gralloc driver...
I have a one more thing..
I want to use streamline for Mali profiling.
What version of linux kernel and Mali driver was verified for gpu profiling?
Or should I change something in my setting?
I am so ignorant about this.
Kindly let me know.
or tell me which phone can use to Mali profiling with streamline
Thank you

Hi,
I have received as gift a 7" inch android tablet.
The brand is Novotech.
It is a 7" 16/9 tablet with Android 4.0.3
CPU is MIPS 74Kc V5.0 FPU V0.0
Antutu is telling
model PWS700EJR
device GS701b
800 x 480
GPU Vendor : Vivante Corporation
GPU Renderer : GC800 Graphics Engine
cpuinfo : MIPS Processor
I would like to root it but impossible to have adb working.
USB Debugging is activated and I can see in the taskbar the debug notification.
In the computer manager, the device is well found.
I have tried the generic google USB drivers. Device is shown as Android Composite ADB Interface
Also tried the PDANet Other device driver and then is shown as Android ADB Interface
In both cases, when making a ADB DEVICES, result is always blank.
Any idea to have ADB working ?
Many thanks
Got the same device over here, slow as hell, any possibilty to downgrade to an earlier version of Android?

Hello.
Is it possible to modify GT-I9505-2/kernel/arch/arm/boot/dts/msm8974-gpu.dtsi to reduce the powerlevel of the GPU ? (I get the source from samsung open-source website)
When I change theses values, nothing happen, this is exacly the same value. (cat ./sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/gputop or {k,j}probes drivers/gpu/msm/kgsl_pwrctrl.c functions).
Thanks.
i'm not expert in QCT CPU numbering, but msm8974 is Snapdragon 800.
** - I'm using mobile devices using Snapdragon 801 msm8974ab
- I changed the code in the kernel opensource path:
arch / arm / boot / dts package but when I overclock kernel has yet been ./. So I ask you to revise the opensource code file in the kernel to get overclocking on this chip
Sorry for my english is not fluent ./. Looking forward to receiving your reply !!
Hello all,
I have recevied an old tablet "goClever i102 ( Airis Kira N10020) and it is slow.
Here are it's specifications:
• 10" Wide TFT (1024x600)
• ARM11 up to 1 GHz Processor
• Memory 512 MB DDR2
• Storage Flash 4 GB
• WLAN - LAN 10/100
• mini HDMI - Web-Cam - 4x USB
• micro SD/SD-HC Card Reader
• Dimensions 246.6 x 172.7 x 24.5 mm.
• Weight ~ 0.90 Kg.
• Android 2.3 OS
The manufacturer's page for the device:

Here are some aditional informations I gathered by openning it:

I rooted the device and I posted the instructions here:
http://forum.xda-developers.com/android/help/rooting-goclever-i102-n10020-t3119091
I would like to install on it Arch linux or some other linux core.
I set up a virtual machine with linux, installed a cross-compiler and the toolchain to build for ARMv6 processors and then I tried to build a bootloaded and a kernel for the tablet. It succesfuly built the kernel, just to test the toolchain ,but soon I realized that I could not configure u-boot for this specific processor. I could not find any pre-made configurations files for it. I don't have much knowledge about how to build a kernel or a bootloader.
Could anyone help me regarding this issue or give some instructions how to manually configure u-boot?
PS: I tried to boot on some RasberryPi softwares that I could find on the internet but it did not boot. Also I tried some linux software for the tablets Airis Kira N7000 / N8000 / N9000 that I found here: https://kirbian.wordpress.com/descargas/airis-kira-n7000-n8000-n9000/ ,and booted the kernel for a very short time(it displayed something like uzImage.bin and a loading bar), but then the screen went black with the cursor blinking on the left. After this it remains in this state, nothing loads or changes. After I reboot it, it loads the stock rom (Android 2.3.3)...
Thank you in advance!
Hi
I'm trying to boot up remix OS in HDD on a Toshiba laptop of 2006 with those specification
Intel Celeron M370
ATI Graphics
512 MB of ram
80 GB HDD
After successful installation it normally reboot to boot manager and I can select remix os to boot, and then it says:

Then there is a problem, because after 2 seconds it says:
[ 1.959044] intel_powerclamp: Intel powerclamp does not run on family 6 model 13
[ 1.961135] intel_rapl: driver does not support CPU family 6 model 13
Click to expand...
Click to collapse
I know that hardware is much weak, but seems like there are problems with powerclamp and intel_rapl, somethings related to driver.
There is something I can do to boot up Remix OS on this PC?
I have the same problem. But mine says "Cpu family 6 model 23"...
My laptop is a Samsung R430 from 2010.
Core 2 duo T6600 2.2GHz
6GB RAM
I'm trying to run it form usb though.

Maybe some CPUs families aren't currently supported.
I could boot Remix OS on Intel Celeron 1007U x64 and on an Intel Core i7 2nd generation.
Someone can confirm?
hmm..
I also see this at boot... : intel_rapl: driver does not support CPU family * model * (intel d525)
But RemixOS 32bit is booting/working fine
Its some kind of cpu throtle driver ( to keep heat down ) if I read correctly
https://wiki.ubuntu.com/Kernel/PowerManagement/ThermalIssues
My system.. however.. is running cool (so, the driver is not needed)
A thought::
Try booting with : DEBUG=1
