X11/GLESv2/LayerManager bring up on Wandboard (i.MX6 Solo) help

[vikaspatil]

Dear All,

I am able to start the X11 (version 1.12.3) and run demos from "fsl-gpu-sdk-1.1" on Wandboard Solo(i.e. i.MX6 Solo). I have built the graphics driver, xorg driver  and fsl-gpu-sdk from daisy branch of meat-fsl-arm from Freescale git(https://github.com/Freescale) and copied to custom filesystem which has Xorg version 1.12.3.

Platform: Wandboard

Kernel: 3.10.17-1.0.0-wandboard-02434-g7eb9930 #5 SMP PREEMPT Wed Jul 23 11:45:33 IST 2014 armv7l GNU/Linux

GPU Driver: gpu-viv-bin-mx6q-3.10.17-1.0.0-hfp

Xorg Driver: xserver-xorg-video-imx-viv-3.10.17-1.0.0

Vivante SDK demo: fsl-gpu-sdk-1.1

Display: HDMI with following mode

Attached here:

xorg conf: xorg-imx6.conf

log of Xorg:Xorg.0.log

log of layermanaher: LayerManagerService.log

I would like to understand and fix following issues which I am facing currently.

1) I am seeing following error in Xorg log after starting X11, How can I fix this and what is the significance of it? Or Is it ok to live with it?

[  1136.588] (EE) VIVANTE(0): fb memory is not big enough to hold shadow buffer!

2) I can run demos from fsl-gpu-sdk-1.1 and see on display but when I run demos from /opt/viv_samples/vdk from package "gpu-viv-bin-mx6q-3.10.17-1.0.0-hfp" can't see anything on display. How can I run these demos and see on display?

3) I would like to run GENIVI LayerManager on above setup (i.e. X11 and GLESv2). I have build the layer manager 0.9.9 and copied to filesystem. However I can start LayermanagerService and EGLX11MockNavigation but can't see anything on display and from the log it seems it is running?

Could anyone suggest me what is going wrong here? or Is there any limitation running this?

I start X11 and layer manager using following commnds:

# /usr/bin/Xorg -config /etc/X11/xorg-imx6.conf -retro -quiet -ignoreABI &

# export DISPLAY=:0.0

# LayerManagerService -c4 -f4 -w1280 -h720 &

# EGLX11MockNavigation &

Waiting for experts comments/suggestions. Thanks for your time for reading this.

Thanks & Regards,

Vikas

Dear All,

I am trying to run the GENIVI Layermanager IVI  examples on wandboard using following components mentioned below. Looking at the meta-fsl-ivi, it seems it can be configured with two different configuration as follows.

Components:

Platform: Wandboard Solo (Freescale i.MX6 Solo)

Kernel: https://github.com/wandboard-org/linux/tree/wandboard_imx_3.10.17_1.0.0_ga

Vivante GFX drivers: https://github.com/Freescale/meta-fsl-arm/tree/daisy/recipes-graphics

fsl-gpu-sdk: https://github.com/Freescale/meta-fsl-demos/tree/master/recipes-graphics/fsl-gpu-sdk

Genivi IVI: https://github.com/Freescale/meta-fsl-ivi/commits/master

Virtual FB driver: https://github.com/Freescale/linux-module-virtfb

Filesystem: custom with above components

1. Using Virtual framebuffer driver (VFB) and MXGAL graphics backend

- I am able to configure this and run the "EGLVFBMockNavigation" layermanger application successfully, however I see continuous black strip flicker in middle of application even after I kill the application. Also following messages keep coming continuously in serial console. Attached here the screen snapshot.

VFBMXGAL                    | DEBUG   | Surface to be bound is /dev/fb5

MXGALGraphicsystem          | DEBUG   | renderSurface bound 11

VFBMXGAL                    | DEBUG   | Surface to be bound is /dev/fb5

MXGALGraphicsystem          | DEBUG   | renderSurface bound 11

VFBMXGAL                    | DEBUG   | Surface to be bound is /dev/fb5

MXGALGraphicsystem          | DEBUG   | renderSurface bound 11

VFBMXGAL                    | DEBUG   | Surface to be bound is /dev/fb5

MXGALGraphicsystem          | DEBUG   | renderSurface bound 11

Is there any one who tried these and observed the same?

Is this the known state of this software ((meta-sfl-ivi , meta-fsl-arm, kernel etc) )?

Is this due to some known limitation?

Is there any fix available for this issue?

2. Using X11 graphics backend without VFB

- I am able to launch the "EGLX11MockNavigation", however nothing comes on display (black screen).

- I tried with layer-management-0.9.9 (which is there on custom filesystem and runs fine on another vendor's platform) other than layer-management-0.9.6 (from meta-fsl-ivi). With this both versions behaviour is same, nothing on screen but the black screen.

Is this the known issue to anyone? or Is there any fix available for this too?

Which version and what configuration of Layermanager works well with i.MX6 Solo with 3.10.17 kernel?

Notes:

- I need to change the soft links to GAL,EGL,GELEv2 and VIVANTE libraries to switch from X11 to FB gfx backend and vice versa while building and running tests.

- I am able to start the X11 and run X11 based tests from fsl-gpu-sdk. Also able to run the test from /opt/viv_samples with FB backend.

Waiting for experts comments/inputs/suggestions. Thanks for reading the post and your time. I am debugging the above issues right now, I will post my update if I succeed to fix these issues.

Thanks & Regards,

Vikash
