my env:

hardware ----- imx6q with 2GB ddr3 (only use cs0)

software ------  android 13.4 GA bsp

 

software change:

uboot:

config cs0_end to 0x8fffffff , config 0x021b0000 to 0x841a0000

and use this config, i can pass the ddr_stress test with 2GB.

 

kernel:

change mx6q_sabresd_reserve()'s

phys = memblock_alloc_base(imx6q_gpu_pdata.reserved_mem_size,SZ_4K, SZ_1G);

to

phys = memblock_alloc_base(imx6q_gpu_pdata.reserved_mem_size,SZ_4K, SZ_2G);

 

my problem:

In android system,  when moving mouse it would create many mouse shadows, and they don't disappear until you back to home screen or open

a new applications.  you can see it from attachment.

 

any one can give me suggestion about how to fix this problem??
