1,himm: if you wanna know the value and write the value to the register manually, you can use this command in bash .General for debug.
2,mmz.ko ,you know a part of the DDR memory is managed by OS, mmz manage the memory related with Media.
Q:
what is params of mmz.ko
insmod mmz.ko mmz=anonymous,0,0x84000000,442M:jpeg,0,0x9fa00000,5M:ddr1,0,0xC0000000,511M anony=1 || report_error
It's mean the mmz have three memory zone. The first named "anonymous" start at 0x84000000,the size is 442M. The second named jped.....

your second question must pay attention bootargs for OS memory.
the params of hifb.ko? video display memory for each layer.more detail, please read the doc " Graphics development user guide".

So, As I understand some memory managed by Linux kernel (OS) and some memory managed by MMZ. Memory managed via MMZ used by HI3531*.ko modules.
Memory adress of DDR begins from 0x80000000.
Kernel is loaded from 0x80008000 and than I have some memory (my board have 128M).
For example TDE and HiFB needs some memory, and I allocate memory for them via MMZ.

Ad I right that, if I have total 128M on my board, and I want to give 64M of memory for OS and other 64M for Media. I need load kernel with parameter mem=64M, after
insert mmz.ko with params like mmz=anonymous,0,0x84000000,64M?

What does mean anony=1 parameter?

annoy is a switch. ”annoy = 1" means malloc buffer from mmz named "anonymous".
For example, VI need one buffer, and you don't appoint one mmz for it, then VI aquires one from "anonymous".
So you just always set annoy to 1.
