Hi Siarhei

I have built u-boot02015.01 and latest stage/sunxi-3.4 kernel (four memory 
chips 512Mx8 on the board) and trying to use lima-memspeed utility.

$ ./lima-memspeed gpu_copy

GPU jobs works properly but PP jobs crashes the system (I have inserted 
printf() functions to your code and ...).

I have found the point where the system reboots. It happens when we call 
LIMA_M400_PP_START_JOB_R3P0..

G2P and FB allocation is follow:

SYS: 0x43000000 - 0x4300FFFF ( 64 KB)
G2D: 0x50000000 - 0x57FFFFFF (128 MB)
LCD: 0x58000000 - 0x5FFFFFFF (128 MB)

dcdc3 vol 1300000 uV

system crashes exactly during the IOCTL:

limadriver/limare/lib/jobs.c~410:

int limare_m400_pp_job_start_r3p0(
  ....
   ....

   ret = ioctl( state-fd, LIMA_M400_PP_START_JOB_R3P0, &job);

 
probably this error related to translation physical addresses in the kernel 
mali driver when we access to pixel processors.

Please advise how to fix this error or make some workaround. 

Thanks in advance.
Andrey K.
