I would like to decode 4 files at the same time,
so, I have to increase the memory size for decode because of the multi thread structure.
but when I mofidy the loadmodules.sh below:
insmod cmemk.ko phys_start=0x87800000 phys_end=0x93e00000 pools=3x4147200,30x3458400,30x1434240,33x663552,12x60000
it crash the whole system...and show below error message:

What are the limits of phys_start and phys_end if I wish to do 4 files decode simultaneously ???
Update:
below is workable setting of cmemk. but it is not enough to decode 4 files simultaneously.
The pools need to adjust for decode, does anyone know how to set up them?
insmod cmemk.ko phys_start=0x87800000 phys_end=0x8fc00000 pools=2x4147200,20x3458400,20x1434240,22x663552,8x60000
