how to enable firefly rk3288 reload openGL/CL feature?

dalton.lai

hi,

1. I have compiled the kernel 3.10 and copy compiled mali_kbase.ko into /system/lib/modules.

2. And, copy below Midgard GPU User-Space Binary Drivers into /usr/lib.
    mali-t76x_r5p0-06rel0_linux_1+fbdev.tar.gz
    mali-t76x_r6p0-02rel0_linux_1+fbdev.tar.gz

3. lsmod to check if the mali_kbase.ko have loaded as below
   Module                  Size  Used by
   mali_kbase            240797  0

4. make sure we have full permission to access:
    /dev/mali0
    /dev/fb*
    mali_kbase.ko
    Midgard GPU User-Space Binary Drivers

5. check the kernel space driver in kernel source (seems modified from TX011-SW-99002-r6p0-02rel0.tgz)

6. follow below thread to setup fb

But, it seems still not work:
firefly@firefly:~$ sudo clinfo
I: ICD loader reports no usable platforms

firefly@firefly:~$ sudo glmark2
** GLX does not support GLX_EXT_swap_control or GLX_MESA_swap_control!

So, any one can help to guide me to debug for this problem?
Thanks a lot.

hi isle,

thanks a lot for your information.
I have test with Firefly-rk3288_Ubuntu_1604_2016_08291523_Beta.img on reload board, and openCL/openGL ES both works well, except VGA i2c4 keep prompting in console to lag the system. (appended logs as below)

[ 1722.064489] rk3x-i2c ff160000.i2c: timeout, ipd: 0x80, state: 2
[ 1722.164485] rk3x-i2c ff160000.i2c: timeout, ipd: 0x80, state: 2
[ 1732.284885] rk3x-i2c ff160000.i2c: timeout, ipd: 0x80, state: 2

anyway, it works, thank you.
