sgx-startup.sh problem with bone-debian-8.7-iot-armhf-2017-03-19-4gb image
LucaVs opened this issue · comments
I'm using the latest Debian image:
bone-debian-8.7-iot-armhf-2017-03-19-4gb image
I followed the instruction from:
http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black
to get SGX available.
- I installed the latest 4.4 kernel (--bone-kernel --lts-4_4)
- I installed GFX_5.01.01.02.tar.gz .
It seems there's a problem with sgx-startup.sh .
When I reboot the BBB I can't find omaplfb module loaded.
After rebooting I executed the following command:
root@beaglebone:~# lsmod | grep omaplfb
(no result)
root@beaglebone:~# sh /etc/init.d/sgx-startup.sh start
sgx: Starting PVR
/usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=129)
root@beaglebone:~# lsmod | grep omaplfb
omaplfb 12142 0
tilcdc 26645 1 omaplfb
pvrsrvkm 155855 1 omaplfb
now it works.
It seems at boot time it can't start itself.
I can get SGX properly running by disabling startup execution of sgx-startup.sh
chmod -x sgx-startup.sh
and by adding the following lines to rc.local
sleep 5
sh /etc/init.d/sgx-startup.sh start
without the sleep it doesn't starts.
It probably start too fast at boot time while it should wait for some services to start before...
this really needs to be converted to a systemd startup script, i bet it's waiting for rootfs to load.. ;)
I create a simple service:
[Unit]
Description=SGX
[Service]
ExecStart=/bin/sh /etc/init.d/sgx-startup.sh start
ExecStop=/bin/sh /etc/init.d/sgx-startup.sh stop
Restart=on-failure
RestartSec=10
User=root
[Install]
WantedBy=multi-user.target
but it doesn't load at startup. I get the same error.
If I disable service and run it after login
systemctl start sgx-startup.service
it works...
what should it wait for?
in the unit:
After=local-fs.target
Regards,
Same error.
But I added some log and I get:
modprobe: ERROR: could not insert 'omaplfb': No such device
Could it depend on /dev/fb0 not ready at boot time?
I confirm, when script execute at boot time there isn't /dev/fb0 available.
How can I wait for /dev/fb0 ?
I solved by adding a "while" before modprobe :
while [ ! -e /dev/fb0 ]
do
echo "wait fb0"
sleep 1
done
modprobe omaplfb
@LucaVs thanks! merged that (and tested it)
👍
Thanks for your work!
I just tried following the instructions here: http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black
When I check for omaplfb using lsmod, I don't see it. However, I do see pvrsrvkm.
lsmod | grep pvrsrvkm
pvrsrvkm 4379100 0
Looking at the startup script, it looks like you also wait for pvrsrvkm.
while [ ! -d /sys/class/pvr/pvrsrvkm/ ]
do
echo "wait pvrsrvkm"
sleep 1
done
It doesn't look like that path exists on my device, so the startup script gets stuck there.
@tderensis probally didn't install teh bone kernel:
http://elinux.org/BeagleBoardDebian#Mainline_.284.4.x_lts.29

Ah, I didn't realize I needed the bone kernel. I currently am using:
Linux beaglebone 4.4.52-ti-r92 #1 SMP Sat Mar 11 01:40:33 UTC 2017 armv7l GNU/Linux
What are the differences between these kernels? I am currently using the Beaglebone Green Wireless and using sleep modes along with an RGB display. Does that kernel still support these features?
@tderensis the 4.4.x-ti kernel has the new SGX driver stack. It's EGL only, FBDEV got removed. to use it:
sudo apt install ti-sgx-ti335x-modules-`uname -r`
sudo depmod -a `uname -r`
sudo update-initramfs -uk `uname -r`
then this userspace:
git clone -b ti-img-sgx/1.14.3699939 git://git.ti.com/graphics/omap5-sgx-ddk-um-linux.git --depth=1
cd omap5-sgx-ddk-um-linux/
sudo su
export DISCIMAGE=/
export TARGET_PRODUCT=ti335x
make install
exit
#fix: libgbm.so.2 (one line:)
sudo ln -s /usr/lib/arm-linux-gnueabihf/libgbm.so.1 /usr/lib/arm-linux-gnueabihf/libgbm.so.2
sudo modprobe pvrsrvkm
sudo /usr/bin/pvrsrvctl --start --no-module
and that's as far as i've gotten.. your on your own.
These steps worked to get the pvrsrvkm module installed and the pvrsrvctl program starts. If the new SGX driver stack only supports EGL, then should I be using weston if I want accelerated video using EGL? Or should I be able to use lxqt?
I tried weston, but it fails to start unless I run it with --use-pixman.
I tried the same way that @LucaVs tried (following this) but the module fails to load on boot. The log output doesn't show much:
Apr 21 15:24:33 beaglebone systemd[1]: Starting LSB: Start daemon at boot time...
Apr 21 15:24:33 beaglebone sgx-startup.sh[716]: sgx: Starting PVR
Apr 21 15:24:34 beaglebone sgx-startup.sh[716]: /usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=4)
Apr 21 15:24:35 beaglebone systemd[1]: sgx-startup.service: Control process exited, code=exited status=1
Apr 21 15:24:35 beaglebone systemd[1]: Failed to start LSB: Start daemon at boot time.
Apr 21 15:24:35 beaglebone systemd[1]: sgx-startup.service: Unit entered failed state.
Apr 21 15:24:35 beaglebone systemd[1]: sgx-startup.service: Failed with result 'exit-code'.
Starting it afterwards also does not work either. At that point the kernel starts spewing messages. One small difference I noticed is that my GFX that I created is named differently: GFX_5.01.01.02_es8.x.tar.gz. Also running the update_kernel script automatically installs ti-sgx-es8-modules-4.4.61-bone17. I believe this is needed, but I am not entirely sure.
