Bug Description

Currently a dedicated 32MB chunk of memory is allocated for the Mali GPU with mali.mali_mem=32M@128M on the default kernel command line u-boot inserts.

For GB we use 64MB because we used to easily run out of dedicated memory with 32MB.

I don't have logs handy but I believe we are hitting this with ICS as well. I've seen messages from mali stating that it's falling back to using system memory, if I've interpreted those messages right.

We should look into increasing this for ICS too.

X.Org doesn't probably use the GPU memory as much as Android does, so on that side it's not as critical I guess.

The fix must be done in LAMC for Android parts.

In /media_create/android_boards.py

replace
        'earlyprintk mem=128M@0 mali.mali_mem=32M@128M hwmem=168M@160M mem=48M@328M mem_issw=1M@383M mem=640M@384M vmalloc=256M')

with
        'earlyprintk mem=128M@0 mali.mali_mem=64M@128M hwmem=168M@192M mem=22M@360M mem_issw=1M@383M mem=640M@384M vmalloc=256M')
