hi everyone
i use streamline for Mali profiling
but i cant understand "Instruction failed texture-miss count"
And if failed texture-miss count is high
what should i do to reduce "Instruction failed texture-miss count"
thanks!

Hi, all
When I'm reading mali kernel driver source r3p2-01rel4, I get confused with some code
* Is the UMP an essential component for Mali linux kernel device driver?
* There are macros that set up the Mali GPU resources in mali_utgard.h header file…
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…
Hello ARM Mali devs,
We recently released an app that was pretty meticulously tested against different variants of Mali chips. However, post release we have received a wide variety of issue reports on MALi 400/450, mostly paired with Rockchip CPUs (Memopad…

I am trying to render to just a rectangular portion of the frame. To my knowledge there are two options for this - glScissors and glViewport.
When profiling with DS-5 Streamline on both Mali-400 MP and Mali-450 MP, the number of rasterized fragments is…
I ran Streamline on the SimpleTriangle example from Mali OpenGL ES SDK for Android v1.6.0. Basically, each frame it renders a triangle, that covers half of the frame. It renders to the default framebuffer. What I observe is, that most of the time is spent…
Hello
Are there any possible way how to properly(without loss of quality) render photo pictures ( as texture in opengl ) on Mali 400/450 if we have only available 16bit precision fragment shader?

Hi,
I'm working on an algorithm where I need to detect if the current `gl_FragCoord` is an even or odd row/column. A typical implementation would look something like `if (mod(gl_FragCoord.x, 2.0) < 1.0) { ... } else { ... }`. After running into…
Dear all,
I'm having hard time compiling Mali Utgard linux driver against mainline 4.16 kernel. Because I'm using meta-xilinx yocto layer, r8p0-01rel0 version of driver is being built. The trick here is that Xilinx assumes that their default kernel (based…

What is the screen size after you most suited to MALI 450 mp ?
Of course it can support 1080p . But I think that the processor will be more comfortable with a 720p right ? refresh screen can be more improved in 1080p ?

Hi,
I have recently encountered a problem with OpenGL/EGL on ARM Mali 450, Android 4.4.2. In my opinion this is a bug.
I have the following setup. A texture with no storage and a frame buffer attached to the texture. An EGLImageKHR is set as the texture…

Hi,
As I know, the lastest version of midgard DDK can support wayland egl.
Is there any plan to support it for mali400(utgard)? or do you already have the supported version?
Thanks.
Good morning.
I am looking for User Space Driver for X11 of Mali-450.
But I looked but only fbdev and wayland exist and x11 is not found.
I use a board called "ODROID-C1" (ODROID-C1 board uses Mali-450).
This board provides the Mali User Space…
