Then i run startx, i can see the desktop on the monitor.

But i found that the X process doesn't load any EGL and GLES libs by seeing the info of /proc/X process ID/task/*/smaps file.

Most X11 desktop environments use OpenGL, not OpenGL ES. Then like most embedded GPUs, Mali-450 only supports OpenGL ES so the X11 desktop is not hardware-accelerated.

...

[ 23.793] (II) GLX: no usable GL providers found for screen 0

This means that although X11 found a valid armsoc driver and is enabled to run OpenGL ES apps it won't run desktop-like OpenGL apps or desktop environments that need OpenGL.

If you run an accelerated OpenGL ES X11 app such as es2gears then it should work and use the Mali driver. I guess this is what es2_info is trying to do except that it looks like something went wrong in your driver build or configuration. That would take more investigation to find out the actual cause; might be related to how GPU registers are being used in the kernel, or how buffers are being used and shared with user-space.

my armsoc video driver is simple, i past the patch bellow. Actually, since i didn't implement any custom gem but do implement the prime and dumb in the kernel DRM driver, so i implement the create_custom_gem function just with the DRM_IOCTL_MODE_CREATE_DUMB ioctl as show bellow. I am not sure it is ok or not?

And my DDK configurations is : make TARGET_TOOLCHAIN=aarch64-linux-gcc TARGET_PLATFORM=default_8a CONFIG=debug VARIANT=mali450-gles-linux-x11-dma_buf

i built both xf86-video-armsoc and DDK at target board. Anything wrong with me?

Hello, Recently, i am working on enabling mali 450 gpu at debian xorg X windows for hikey board which is one of 96boards https://www.96boards.org/.

I first implement xf86-video-armsoc(ver1.1.0) video driver, compile and cp armsoc_drv.so to directory "/usr/lib/xorg/modules/drivers". And then compile arm mali r5p0 DDK and cp egl and gles libs(libEGL.so libEGL.so.1 libEGL.so.1.4 libGLESv1_CM.so libGLESv1_CM.so.1 libGLESv1_CM.so.1.1 libGLESv2.so libGLESv2.so.2 libGLESv2.so.2.0 libMali.so) to directory "/usr/lib/aarch64-linux-gnu/" or "/usr/lib".

What's wrong? Am I missing something on integrating xf86-video-armsoc? And why X doesn't load any EGL and GLES so libs? I paste the Xorg.0.log at the end. Please tell me if you know what's going wrong, thanks.

Hi Xinliang,

I just wanna share my experience on Arndale with you. for me, I put all libraries on /usr/lib/mali/ then touch 1 conf file in /etc/ld.so.conf.d/ like mali.conf and echo the mali libraries path into it. and renew the ld.cache using ldconfig.

i run the ldconfig manually and facing bellow msg. There might be something wrong with the libs compiling, right? I need to check my complie method, i think. Because i do the complie just on the target board not the way of cross compile. # ldconfig /sbin/ldconfig.real: file /usr/lib/aarch64-linux-gnu/libEGL.so.1 is truncated

After startx, I can run the test program glmark2-es2.

Good luck!

Then i run startx, i can see the desktop on the monitor.

But i found that the X process doesn't load any EGL and GLES libs by seeing the info of /proc/X process ID/task/*/smaps file.

Most X11 desktop environments use OpenGL, not OpenGL ES. Then like most embedded GPUs, Mali-450 only supports OpenGL ES so the X11 desktop is not hardware-accelerated.

...

[ 23.793] (II) GLX: no usable GL providers found for screen 0

This means that although X11 found a valid armsoc driver and is enabled to run OpenGL ES apps it won't run desktop-like OpenGL apps or desktop environments that need OpenGL.

If you run an accelerated OpenGL ES X11 app such as es2gears then it should work and use the Mali driver. I guess this is what es2_info is trying to do except that it looks like something went wrong in your driver build or configuration. That would take more investigation to find out the actual cause; might be related to how GPU registers are being used in the kernel, or how buffers are being used and shared with user-space.

my armsoc video driver is simple, i past the patch bellow. Actually, since i didn't implement any custom gem but do implement the prime and dumb in the kernel DRM driver, so i implement the create_custom_gem function just with the DRM_IOCTL_MODE_CREATE_DUMB ioctl as show bellow. I am not sure it is ok or not?

And my DDK configurations is : make TARGET_TOOLCHAIN=aarch64-linux-gcc TARGET_PLATFORM=default_8a CONFIG=debug VARIANT=mali450-gles-linux-x11-dma_buf

i built both xf86-video-armsoc and DDK at target board. Anything wrong with me?

Hello, Recently, i am working on enabling mali 450 gpu at debian xorg X windows for hikey board which is one of 96boards https://www.96boards.org/.

I first implement xf86-video-armsoc(ver1.1.0) video driver, compile and cp armsoc_drv.so to directory "/usr/lib/xorg/modules/drivers". And then compile arm mali r5p0 DDK and cp egl and gles libs(libEGL.so libEGL.so.1 libEGL.so.1.4 libGLESv1_CM.so libGLESv1_CM.so.1 libGLESv1_CM.so.1.1 libGLESv2.so libGLESv2.so.2 libGLESv2.so.2.0 libMali.so) to directory "/usr/lib/aarch64-linux-gnu/" or "/usr/lib".

Most X11 desktop environments use OpenGL, not OpenGL ES. Then like most embedded GPUs, Mali-450 only supports OpenGL ES so the X11 desktop is not hardware-accelerated.

Do you mean it makes no sense that to enable a OpenGL ES mali GPU on X11 desktop environments, such as debain?

...

[ 23.793] (II) GLX: no usable GL providers found for screen 0

This means that although X11 found a valid armsoc driver and is enabled to run OpenGL ES apps it won't run desktop-like OpenGL apps or desktop environments that need OpenGL.

If you run an accelerated OpenGL ES X11 app such as es2gears then it should work and use the Mali driver. I guess this is what es2_info is trying to do except that it looks like something went wrong in your driver build or configuration. That would take more investigation to find out the actual cause; might be related to how GPU registers are being used in the kernel, or how buffers are being used and shared with user-space.

Cheers, Guillaume

Hello, Recently, i am working on enabling mali 450 gpu at debian xorg X windows for hikey board which is one of 96boards https://www.96boards.org/.

I first implement xf86-video-armsoc(ver1.1.0) video driver, compile and cp armsoc_drv.so to directory "/usr/lib/xorg/modules/drivers". And then compile arm mali r5p0 DDK and cp egl and gles libs(libEGL.so libEGL.so.1 libEGL.so.1.4 libGLESv1_CM.so libGLESv1_CM.so.1 libGLESv1_CM.so.1.1 libGLESv2.so libGLESv2.so.2 libGLESv2.so.2.0 libMali.so) to directory "/usr/lib/aarch64-linux-gnu/" or "/usr/lib".

There are two dma_map_ops implementations of swiotlb for arm64, that are: noncoherent_swiotlb_dma_ops and coherent_swiotlb_dma_ops. By default,device driver use the noncoherent one. In our case, the buffers, which allocated in display drm driver, are coherent. So we need to add a "dma-coherent;" property to both display drm and gpu driver dts node to make sure our drm and gpu driver use the coherent one. Now i can run OpenGL ES application now, such as es2gears.

Then i run startx, i can see the desktop on the monitor. But i found that the X process doesn't load any EGL and GLES libs by seeing the info of /proc/X process ID/task/*/smaps file.

Most X11 desktop environments use OpenGL, not OpenGL ES. Then like most embedded GPUs, Mali-450 only supports OpenGL ES so the X11 desktop is not hardware-accelerated.

This is somewhat unrelated to the issue of the armsoc driver being a bug pile that makes your system crash.

However, both GNOME and KDE can use OpenGL ES for desktop acceleration.

Do you know if Debian desktop can use OpenGL ES for acceleration? And how?

Other desktops use Render or whatever acceleration which is actually

faster for small scale effects when done in software but can be a bit sluggish for large window moves/resizes on slow CPUs.

[ 23.793] (II) GLX: no usable GL providers found for screen 0

This means that although X11 found a valid armsoc driver and is enabled to run OpenGL ES apps it won't run desktop-like OpenGL apps or desktop environments that need OpenGL.

There is a shim library to translate OpenGL calls to OpenGL ES calls so you can run desktop OpenGL applications that use OpenGL features for which the translation was already added. I don't remember the exact library name, unfortunately.

I have searched for it on the internet, but i can find it. If you remember the lib name please tell me.

Thanks

Michal
