Just checked 3.10.17 and there the size of gcsHAL_INTERFACE is 248, the same as used by the libs in gpu-viv-bin-mx6q-3.10.31-1.1.0-beta. So the libs seem to have been compiled against headers with an old gcsHAL_INTERFACE and are therefor unusable with kernel 3.10.31. Here is a small test program one can check against kernel 3.10.17 and 3.10.31: ----------------------------- #include #include "/usr/src/linux/drivers/mxc/gpu-viv/hal/kernel/inc/gc_hal.h" int main(void) { printf("Size: %u\n", sizeof(gcsHAL_INTERFACE)); return 0; } ----------------------------- Regards, Alexander Holler
