Hi!
I have a game in Google Play and I'm having problems with (at least) one of the devices, the Galaxy S3 mini with a Mali-400MP.
There's a shader which takes 20 to 30 seconds to be compiled, leading to users thinking that the device just crashed.…

Hello, newbie right down to the socks here, but have to ask. From what I've seen most arm cpu/gpu are scaled to to what number of GPU it will use. I have a Allwinner A31S processor on a device that I know that should be Mali 400 MP4, but it…
I had a topic question on the old forum which shown an issue with the Mali-T6xx driver being terribly slow with both glBufferSubData and glMapBufferRange with the unsync bit set.
I was wondering if there has been any information on if the situation has…
When android 4.4 is showing a video in full screen mode, we wish to temporary turn off mali to reduce device's power.
Once user touch screen, some video playing UI must be showed. so we must turn on mali quickly.
Is it possible to turn on/off mali dynamically…
Hello.
I am developing a games for android.
There is a device Samsung Galaxy S3 with gpu Mali-400MP, android version 4.3.
I have a problem when rendering buffer in parts. I wrote a test application to demonstrate the problem.
First I created a vertex b…
Hi, everyone!
I am a student at present, I am learning something about development of GPU driver in Linux. I need a device equipped with a GPU hardware
for test and study. I think Mali GPU is good choice. But I have no idea that how I'm able to get a cheap…
Hi,
I'm sure this is a very easy question for most of you to asnwer. I sadly seem to be having quite a bt of difficulties to get the driver to compile.
I have compiled the ump.ko kernel module. For that to work i had to uncomment these lines:

I follow steps in here http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0482n/ric1362178383724.html
but still, I can't see GPU fragment in streamline data of ds-5, I can see job manager, GPU tiler and MMU related field.
Anyone know why…
Hi,
I am working on a ARNDALE board which consists of a Mali T604 GPU. I have an application developed with OpenCL which runs fine on this board. The application uses buffer memory. Now I want to use texture memory instead of buffer memory. I changed…
I saw another post mentioning the Samsung Chromebook 2 on this forum but I thought I'd ask the question outright. Are there any or will there be any plans for ARM to release OpenGL ES and Open CL drivers for HW accel support on the new Samsung Chromebook…

Hi,
I'm sing a Galaxy Note3 with ARM GPU T628. I'm able to get access to the all GPU performance counters but not to the filmstrip feature.
Anyone knows how to get it working?
Regards,

For Mali T604 and T628, peak performance is 17 FP32 FLOPS per ALU per cycle.http://malideveloper.arm.com/downloads/OpenCL_FAQ.pdf shows this is compsed of:

Hi, I wanted to know because I can not find any information, few gigaflops render gpu graphics MALI T624 MP6 riding the Neo Galaxy Note 3, this level of snapdragon 600 GFLOPS? a hug
Hello,
I just followed the manual but I cannot get the MGD to intercept any call from my app.
The GUI connects to de daemon though USB but no data is traced.
I am using Android 4.4.2 and Mali-400 MP.
Am I missing something?
Summary
Is OpenCL support for the Mali-T628 (for example as found in the Exynos 5420 SoC on the Arndale Octa board) available? If so, how to set it up?
More details
According to the vendor, OpenCL should be supported, but the Arndale Octa Wiki does not…
Hi,
Nice tools you're offering, I really love the offline compiler, and it really fits well in our pipeline to deliver shader to arm/mali mobile (unit tests and debug).
Now we'd like to advance on the perf departement, but I'm having hard time to figure…
Hello everyone,
Based on OpenCL guide for Mali 600 gpu, CL_MEM_ALLOC_HOST_PTR should be used to remove any data copy and to improve performance.
Today, I was testing on memory copy time using CL_MEM_ALLOC_HOST_PTR on Arndale board having a Mali 604 gpu…
I'm working on accelerating sqlite using OpenCL on Mali. It's going reasonably well but it'd be great to have a guide.
Thanks!

I was looking for a way to install Linux with Mali GPU support on my Samsung Nexus10, so I find the guide at : http://malideveloper.arm.com/develop-for-mali/features/graphics-and-compute-development-on-samsung-chromebook/

Is this not the correct approach to asynchronous texture loading on Android?
Are there any transformation/conversation if I allocate texture from OpenGL application user space to some GPU internal format?
And is it possible to disable this transformation?
16 or 24 or 32bit texture
Are there any disadvantages ?
For example if I allocate…
Hello dear community members,
I've got mk908 which has gor ARM rockchip 3188 with android, so I flashed it and with oleg0's kernel 3.0.36+ (you can find who is he and his kernel) and I tried to us my rootfs which is Linux gentoo based root and everything…
Hi.
Usually, I use render-to-texture technique to process the image.
However, recently, I need to read the contents to the system memory.
So, I tried to use glReadPixels as follows:
GLubyte pixels[256] = { 0, 0, 0, 0 };
GL_CHECK( glReadPixels(100, 100, 2,…
after I read the code of mali-400/450 linux kernel driver r3p2-01rel4, I have a doubt that if it is really able to support DRM.
(because of the lack of Mali device, I failed to give a try)
Take an example from drm_sman_mm, Mali's drm_sman_mm callbacks almost…
