I'm a newcomer to the TI community, and have just started working on the Beagleboard-xM. My short-term goal is run Gentoo on the Beagleboard-xM.
I use hard float-abi (my gcc option -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8). I have building Qt 4.7.1. I wont use OpenGL ES accelerated by SGX. Can I do this with hardfloat toolchaine?
The SGX libraries are built with softfp with NEON enabled. You will not be able to mix them with the hard option.
Hello.
Now I use Gentoo softfloat toolchain on the Beagleboard xM. I use 2.6.37 patched kernel (from https://code.launchpad.net/~beagleboard-kernel/+junk/2.6-stable-sgxtest)
To init PVR I use init_script:
#!/sbin/runscript
depend() {
}
start() {
ebegin "Starting PVR"
modprobe omaplfb
modprobe bufferclass_ti
pvr_maj=$(grep "pvrsrvkm$" /proc/devices | cut -b1,2,3)
bc_maj=$(grep "bc" /proc/devices | cut -b1,2,3)
if [ -e /dev/pvrsrvkm ] ; then
rm -f /dev/pvrsrvkm
fi
mknod /dev/pvrsrvkm c $pvr_maj 0
chmod 666 /dev/pvrsrvkm
touch /etc/powervr-esrev
SAVED_ESREVISION="$(cat /etc/powervr-esrev)"
devmem2 0x48004B48 w 0x2 > /dev/null
devmem2 0x48004B10 w 0x1 > /dev/null
devmem2 0x48004B00 w 0x2 > /dev/null

echo Es_Revision Determinate
if [ "${ES_REVISION}" != "${SAVED_ESREVISION}" ] ; then
echo -n "Starting SGX fixup for"
echo " ES${ES_REVISION}.x"
cp -a /usr/lib/ES${ES_REVISION}.0/* /usr/lib
cp -a /usr/bin/ES${ES_REVISION}.0/* /usr/bin
echo "${ES_REVISION}" > /etc/powervr-esrev
fi
/usr/bin/pvrsrvinit
eend $?
}
stop() {
ebegin "Stopping PVR"
rmmod bufferclass_ti 2>/dev/null
rmmod omaplfb 2>/dev/null
rmmod pvrsrvkm 2>/dev/null
eend $?
}

Can you help me with this situations?
Can you post the full log, starting from the pvr script invocation, and the steps you followed ?
Also need the log of the gfx_check.sh script from below.
We do not validate against Gentoo. We will try to see what is happening here...

I do :
1. Patch 2.6.37 vanilla sources kernel with patch from https://code.launchpad.net/~beagleboard-kernel/+junk/2.6-stable-sgxtest
2. Enable in config DSP and SGX in kernel staging section.
3. Build kernel and modules.
4. cp to /etc/init.d/pvr pvr_init script
5. rc-update add pvr default
6. cp bin and lib directory to the target from the target_libs.tar.gz.
7. reboot
After this I recive log from the previos post
Good to see that you are using the latest drivers.
We have tested against the below kernel. Is there a way you can try the below kernel ?
