I am having trouble getting the SGX libs to work properly with kernel 3.13 from https://github.com/RobertCNelson/linux-dev. I did have to modify sgx_build_modules.sh to enable FBDEV, my requirements are no X. The first sign of trouble is during the build of the SGX libs I am seeing this warning:
Building modules, stage 2. MODPOST 3 modules WARNING: "unregister_vsync_cb" [/home/fse/Documents/BBB/linux-dev/ignore/ti-sdk-pvr/Graphics_SDK/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb.ko] undefined! WARNING: "register_vsync_cb" [/home/fse/Documents/BBB/linux-dev/ignore/ti-sdk-pvr/Graphics_SDK/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb.ko] undefined! This however does not stop the build. After installing the kernel/modules then booting up the BBB I get the following error when trying to kick off the PVR service: # /etc/init.d/rc.pvr start [ 137.596132] omaplfb: Unknown symbol register_vsync_cb (err 0) [ 137.602219] omaplfb: Unknown symbol unregister_vsync_cb (err 0) [ 138.046878] omaplfb: Unknown symbol register_vsync_cb (err 0) [ 138.053136] omaplfb: Unknown symbol unregister_vsync_cb (err 0) modprobe: 'extra/omaplfb.ko': unknown symbol in module or invalid parameter This problem came up after upgrading from kernel 3.12 to 3.13. I can see that register_vsync_cb and unregister_vsync_cb are defined in da8xx-fb.c. Maybe this is a linking problem? Has anyone run into this problem before? Any ideas as to what changed between 3.12 and 3.13?
