Hi all,
I'm trying GLES on Snowball board with Mali GPU, without X.
The board was installed linaro-nano 12.07 (with mali400-dev package installed) and had been connected with an TV via HDMI cable; After booting up, I run "hdmistart" command and /dev/fb0 appeared; HDMI ran fine with "cat /dev/urandom > /dev/fb0" command.
However, when testing GLES with sample codes from Mali SDK (http://malideveloper.arm.com/downloads/Mali_OpenGL_ES_2.0_SDK_for_Linux_On_A...)
I got following error: Error: eglGetError(): 12288 (0x3000) Error: No EGL Display available at /root/Mali_OpenGL_ES_2.0_SDK_for_Linux_On_ARM_v1.2.0/simple-framework/src/EGLRuntime.cpp:105
The argument of eglGetDisplay is EGL_DEFAULT_DISPLAY: EGLDisplay display = eglGetDisplay(EGL_DEFAULT_DISPLAY);
So I wonder if Mali can works without X or not? Any help will be greatly appreciate, --- Hiep

Totally under stand :). Hopefully come summer I will be able to get my hands on a board and start contributing :)

Doesnt email run the risk of a patch slipping through the cracks?
as highlighted by Deepak above, each project will use the processes/methods inherited from its 'upstream'. That's why gerrit is being used for Android activities for example. many successful open source projects are using solely email for patch submission and review, and that happens to work fine. yes, that makes lots of emails, and patches can be lost, but the general rule is that it's up to the patch author to follow-up and potentially resubmit when such things happen. for example, the Linux kernel documentation says this:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documen...

Hi Hiep,
This and potential follow on questions are probably best discussed on the Mali forums http://forums.arm.com/index.php?/forum/10-mali-forums/ at least when it comes to the capabilities of the binary driver.

EGL doesn't imply X. For instance Android as of 2.3 (gingerbread) has EGL and there's certainly no X involved in that use case.
The rub as I'm sure you know is that EGL need to be connected to something, X, Wayland, drm...
With Mesa for instance configuring with --enable-egl-platforms=drm would do that, however obviously with the mali driver you're not running Mesa and I would imagine that the Mali SDK provides it's own EGL. It'll be a capabilities of that EGL implementation that you'll be interested in. Thus the reference to make a posting to the Mali fora.
You do bring up a good use case tho and one that seems well worth documenting in a FAQ.
