Hi all,
I'm trying to install SGX-driver for Bealgebone Black. But the driver cannot be loaded.
Modprobe pvrsrvkm doesn't get warning or error. However, the module still not be loaded when checking with lsmod.
I'm using SGX-SDK from
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest//exports/Graphics_SDK_setuplinux_4_10_00_01_hardfp_minimal_demos.bin
With build option:
make BUILD=release OMAPES=8.x FBDEV=yes SUPPORT_XORG=0 all_km
sudo make BUILD=release OMAPES=8.x SUPPORT_XORG=0 EGLIMAGE=1 install_km
The toolchain is linaro-toolchain-4.7
My current kernel is Rowboat kernel 3.2.0 with linaro-nano rootfs (a minimal ubuntu-based rootfs). After running modprobe pvrsrvkm, I see that there's information from dmesg:

I'm not sure why the module cannot be loaded, it was compiled with the kernel, so I think it can't be mismatch.
I followed the instruction from http://processors.wiki.ti.com/index.php/SGXDbg#Unable_to_install_the_kernel_modules_.28pvrsrvkm.ko_or_omaplfb.ko.29
But it seems not to work. My output of gfx_check.sh is as follow:

I don't know where I am wrong, any help will be greatly appreciate.
Thanks a lot,
