Hi, quite like back to march 28th report , I have trouble building sgx librairies against kernel 3.15.6-bone5 from bb-kernel repo.
Building modules, stage 2. MODPOST 3 modules WARNING: "unregister_vsync_cb" [/home/cedric/test-3.8/bb-kernel/ignore/ti-sdk-pvr/Graphics_SDK/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb.ko] undefined! WARNING: "register_vsync_cb" [/home/cedric/test-3.8/bb-kernel/ignore/ti-sdk-pvr/Graphics_SDK/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb.ko] undefined! It builds but on the BBB: modprobe -v omaplfb insmod /lib/modules/3.15.6-bone5/extra/omaplfb.ko ERROR: could not insert 'omaplfb': Unknown symbol in module, or unknown parameter (see dmesg) dmesg: [ 1268.469257] omaplfb: Unknown symbol register_vsync_cb (err 0) [ 1268.469457] omaplfb: Unknown symbol unregister_vsync_cb (err 0) I had the same error for pvrsrvkm, but added CONFIG_FB_DA8XX=y to config Then I patched arch/arm/kernel/setup.c by adding at the end #ifndef MULTI_CACHE EXPORT_SYMBOL(__glue(_CACHE,_dma_map_area)); EXPORT_SYMBOL(__glue(_CACHE,_dma_unmap_area)); EXPORT_SYMBOL(__glue(_CACHE,_dma_flush_range)); #endif This patch solves pvrsrvkm: Unknown symbol register_vsync_cb (err 0) pvrsrvkm: Unknown symbol unregister_vsync_cb (err 0) Any clue ?
