SGX build on DM3730 based beagleboard-xm

Hi,

Have you gone through the pointers in below link & taken care of these points -

http://processors.wiki.ti.com/index.php/SGXDbg#X_fails_to_start

Thanks,

Prathap.

Hi Prathap,

I have tried these steps. Here is what I notice:

1. matrix-gui is not running as seen in ps output.

2. pvrsrvkm fails to load even after depmod -a command. and these dmesg log is seen when trying to insert this module:

[ 41.214904] pvrsrvkm: Unknown symbol drm_pvr_dev_remove (err 0)
[ 41.215393] pvrsrvkm: Unknown symbol drm_pvr_dev_add (err 0)
[ 69.981933] pvrsrvkm: Unknown symbol drm_pvr_dev_remove (err 0)
[ 69.983032] pvrsrvkm: Unknown symbol drm_pvr_dev_add (err 0)

Thanks,

Ketan

Hi Ketan,

The default Kbuild file(under GFX_Linux_KM/services4/3rdparty/linux_drm) works till 3.2 kernel. This is as per the kernel version the graphics SDK release has been validated against and is also mentioned in release notes.

The Graphics SDK 04.10.00.01 release notes mentions the kernel versions validated against -

http://processors.wiki.ti.com/index.php/RN_4_10_00_01#Kernel.28Linux_PSP.29_versions_supported_or_used_for_validation

The same GFX_Linux_KM/services4/3rdparty/linux_drm/Kbuild file has commented section listing the drm files to be used for kernel versions > 3.4. This is to provide reference for users who are using kernel versions greater than what is listed in gfx sdk release notes.Please use that if you are building against kernels >=3.4 & <3.8.

Thanks,

Prathap.

Hi Prathap,

I  tried these steps and still I am getting the same error. Attaching the Xorg.0.log file for reference.

Steps followed:

1. Build kernel and modules for 3.4.7 on Linux Vmware

2. Build Graphics SDK on Linux Vmware with commands:

make BUILD=release OMAPES=5.x SUPPORT_XORG=1 PM_RUNTIME=1 all

make BUILD=release OMAPES=5.x SUPPORT_XORG=1 PM_RUNTIME=1 install

3. Install commands loads files in to a directory ~/targetfs which I tar using tar czf ../sgxbuild.tar.gz * and then untar it on target board at / location.

4. Run ./omap-demo from /etc/init.d directory. 

Please correct me if any changes are required for these steps.

Regards,

Ketan

Hi Prathap,

Got some success with the following changes:

make BUILD=release OMAPES=5.x SUPPORT_XORG=1 all (without PM_RUNTIME set)

Steps on board:

1. run ./omap_demo (these failed to load the pvrsrvkm module). Looks like I need to run this always after reboot.

2.  insmod drm.ko and insmod pvrsrvkm.ko from /lib/module/3.4.7-x1/extra folder

3. Run /usr/local/XSGX/bin/X :0 -verbose -config /usr/local/XSGX/etc/xorg.conf &

4. Run xgles1test1 displays 2 triangles as expected.

I tried running other demos (from /opt/gfxsdkdemos/ogles folder) but with no success. I get such errors:

./OGLESFilmTV: No such file or directory

Thanks,

Ketan

Hi Ketan,

Good to know that you have been able to build the graphics SDK release and get the Xorg driver working with xgles1test1 running fine.

What graphics SDK release package are you using? The release page has muliple packages. For example if you are using Graphics_SDK_setuplinux_4_10_00_01_minimal_demos.bin, then you should be using softfp toolchain & file system.

If you are using the Graphics_SDK_setuplinux_4_10_00_01_hardfp_minimal_demos.bin, then as the name suggests you should be using hardfp toolchain to build the graphics sdk release package and hardfp file system.

Make sure you are using the right toolchain for the package you have downloaded ie if you have downloaded a hardfp package you should be using a hardfp toolchain and hardfp file system only.

Thanks,

Prathap.

Hi Prathap,

I used Graphics_SDK_setuplinux_4_10_00_01.bin and the target filesystem is hardfp. I guess the hardfp toolchain that I need to install is g++-arm-linux-gnueabihf.Can you please confirm?

Thanks,

Ketan

Hi Prathap,

I used the Graphics_SDK_setuplinux_4_10_00_01_hardfp_minimal_demos.bin (and hardfp toolchain) and could even run the OGLESEvilSkull and OGLESFilmTV on the target. However I am facing issues running the demos from ogles2 directory. I tried both OGLES2ChameleonMan and OGLES2MagicLantern demos. Both failed with following error:

symbol lookup error: /usr/lib/arm-linux-gnueabihf/egl/egl_gallium.so: undefined symbol: _XGetRequest

Any pointers towards this? 

Thanks,

Ketan

Hi Ketan,

Good to know that you could get the OGLES demos working on the target.

Also through your mail update, saw that you have OGLES2 demos also working now.

At a preliminary level to see if GPU is being used, you could do cat /proc/interrupts | grep -i sgx to see that SGX interrupts are continously incrementing when you are running the demos. Further for performance analysis and GPU utilization , you can use PVRTune. The below section in sgxdbg page discusses similar topic related to your query -

http://processors.wiki.ti.com/index.php/SGXDbg#Observing_high_CPU_load_and_no_GPU_load_while_running_glxgears

PVRTune can be downloaded from -

Thanks,

Prathap.

Hi Ketan,

I see that you have opened another thread as below for the discussion -

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/537/p/329576/1149395.aspx#1149395

In this context, can you please close the current thread by marking the verified answer.

Further discussions will happen on the new thread you have created.

Thanks,

Prathap.

Hi Prathap,

I do not get verified answer button in this thread and if i click yes for "Did this answer your question?", then also this does not get marked as verified.

Hello Ketan

I also try to start SGX on beagleboard xm (OM3730), but failed.

kernek version is 3.6.7+ from https://github.com/beagleboard/kernel/tree/beagleboard-3.6

I use the Graphics_SDK_setuplinux_4_10_00_01_BinOnly.bin  and cross_compile arm-angstrom-linux-gnueabi-

My steps:

1. Build and install kernel and modules for 3.6.7 on Ubuntu 12.10

2. Build Graphics SDK on Ubuntu 12.10 with commands:

make BUILD=release OMAPES=5.x SUPPORT_XORG=1 all_km

make BUILD=release OMAPES=5.x SUPPORT_XORG=1 install_km

3. when try insmod /opt/gfxlibraries/gfx_rel_es5.x/bufferclass_ti.ko  drm.ko pvrsrvkm.ko error

Hello,

I think you need to look at changes mention at:http://processors.wiki.ti.com/index.php/SGXDbg#Unable_to_build_graphics_SDK_with_SUPPORT_XORG.3D1_for_3.3_.26_above_kernels

i.e. In your Graphics SDK install path, edit GFX_Linux_KM/services4/3rdparty/linux_drm/Kbuild to remove drm_sman.o and add drm_prime.o to list . 

Regards,

Ketan

hello, Ketan

thanks your reply

do what you said, I modprobe pvrsrvkm drm successfully.

But when I run ./xgles1test1  failed

lib/libc.so.6 version 'GLIBC_2.10' not found

thanks

cly

Hello Lin,

I guess you could try  upgrading your distribution or package. I am not sure in this regards as I never faced this issue. Perhaps Prathap could provide you some pointer in this case.

Regards,

Ketan

Hello Ketan,

with your help, I can start the ogles demos with SUPPORT_XORG=0

but, I want to SUPPORT_XORG=1,  error happen

it can insmod drm.ko, while try to insmode pvrsrvkm.ko show error 

[  367.013397] pvrsrvkm: Unknown symbol drm_pvr_dev_remove (err 0)

[ 367.025695] pvrsrvkm: Unknown symbol drm_pvr_dev_add (err 0)

so, I changed the rootfs and kernel using 

ti-sdk-beagleboard-06.00.00.00-Linux-x86-Install.bin  and  Graphics_SDK_setuplinux_4_10_00_01.bin

also some errors when run ./omap-demo

 line 14: /usr/local/XSGX/bin/X: No such file or directory 

according to http://e2e.ti.com/support/arm/sitara_arm/f/791/t/285078.aspx  

this may imcompatibility between ti-sdk-beagleboard-06.00.00.00-Linux-x86-Install.bin  and  Graphics_SDK_setuplinux_4_10_00_01.bin

could you tell which rootfs and kernel you choose so that make the SUPPORT_XORG=1 works

Hello Ketan,

Just a moment after I last reply,  I found when I rmmod drm.ko and insmod drm.ko again then I can insmod pvrsrvkm.ko successfully.

but when I try your step Run /usr/local/XSGX/bin/X :0 -verbose -config /usr/local/XSGX/etc/xorg.conf &

the screen shows nothing and can't input

my rootfs have GNOME X support, then I startup with init 3 level, so does it matters? 

thanks

cly

Hi Lin,

Even I was not able to see anything on the screen, nor was it accepting inputs. But launching of examples from /opt/gfxsdkdemos/ogles worked fine after running "export DISPLAY=:0". As I understand, now the Xorg is based on what SGX is provided i.e. from within /usr/local/XSGX folder. I was able to get touchscreen inputs after modifying /usr/local/XSGX/etc/xorg.conf file. 

How do I check the init level of my startup?

Regards,

Ketan

Hi Ketan,

taht's a good idea modfiying xorg.conf 

you can run runlevel command to get the current runlevel, or open /etc/inittable file edit default init level.

thanks & regards,

cly
