[meta-freescale] 3.10.31-beta: gcoHAL_Construct returns -7 (gcvSTATUS_GENERIC_IO)

[Lauren Post]

You can't mix and match 3.10.17 kernel with 3.10.31 graphics unless you take the 3.10.31 graphics driver and put it on 3.10.17 kernel.   The kernel driver and graphics package must align.

That is why you have build issues.

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 <stdio.h>

#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;
}
-----------------------------
