Android 5.0 lollipop: How Highmem & reserved GPU mem is taken care in latest kernel 3.10+

Hello All,

How Highmem & reserved GPU mem is taken care in latest kernel 3.10+

 

I am trying to port FSL android lollipop version on our imx6s custom board.

 

In boot params when we provide vmalloc= 400M, no change in high mem is observed ?

 

Also the GPU mem should be reserved (256-384M), but when we captured the memfinfo total ram space is available.

 

On Android 4.3 jelly bean which has linux kernel 3.0.35 the behavior was as expected

i.e. 400M goes to High mem

& 256M at the end of ram memory was reserved for GPU.

 

Can anyone explain How these two thing have been taken care in latest 3.10+ kernel.

 

With regards,

Amit
