Issue when running Snowball - GLES without X

by Hiep Pham

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_…) 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 On 04/17/2013 06:26 PM, linaro-dev-request(a)lists.linaro.org wrote: > Send linaro-dev mailing list submissions to > linaro-dev(a)lists.linaro.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.linaro.org/mailman/listinfo/linaro-dev > or, via email, send a message with subject or body 'help' to > linaro-dev-request(a)lists.linaro.org > > You can reach the person managing the list at > linaro-dev-owner(a)lists.linaro.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of linaro-dev digest..." > > > Today's Topics: > > 1.

Mali-ization

by Andy Green

Hi - At the moment the Mali T624 OOT module sources I have do not build against 3.9-rcX / linux-linaro-core-tracking. A colleague checked it and it does build against 3.4. The problems I saw are around ION compatibility but they didn't look tremendously bad. I could work around the problems myself, but it seems to me this might be something that Linaro could solve centrally, dealing with it using the Androidization model - sync a Linaro repo against code drops coming from "upstream", ie, ARM, but keep it always building against llct inbetween. Perhaps even inside llct. I know we're not the only LT in this boat, Anmar mentioned Arndale acceleration is pending, a central Mali-ization tree will also solve that, especially if it's always there and always building in llct already. There may be stuff to take care about for support for different IP revision. But there aren't that many AFAIK. How does this sound to folks? -Andy -- Andy Green | Fujitsu Landing Team Leader Linaro.org │ Open source software for ARM SoCs | Follow Linaro http://facebook.com/pages/Linaro/155974581091106 - http://twitter.com/#!/linaroorg - http://linaro.org/linaro-blog

Yes, IIRC, per the discussion you quote above, I sent this patch for review of our (Linaro's) kernel folks to see if it's ok (the patch is simple, story why it's needed may be not such, though I was positive it's needed).

Question relating to arm

[PATCH] omap4.conf: Disable OMAP2 support

by Peter Ujfalusi

When the kernel is built with CONFIG_ARCH_OMAP2 it will select CPU_V6 and other dependencies which causes issues in user space. For example when clients try to connect to PulseAudio they will crash with: Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:108, function pa_mutex_unlock(). Aborting. Remove support for OMAP2 for now. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)ti.com> --- Hi Andrey, Can you take a look at this patch? In the latest hwpack for panda (with 3.9 kernel) PulseAudio clients all asserts with the following error: Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:108, function pa_mutex_unlock(). Aborting. The same userspace works fine (well, mostly) with 3.8 based hwpacks. It turns out that this is cased by the CONFIG_ARCH_OMAP2, if we disable it PA clients no longer assert. Since the config in question is for OMAP4, I see no issue removing the OMAP2 support since in this way we can get PA working. One issue still remain with PA: None of float resample method works: speex-float-[0-10] However speex-fixed-[0-10] and ffmpeg seams to be working, but it is not perfect. I'll try to figure out why we have this failure since on my Gentoo FS all resample method works fine with the same kernel.
