Does the current r19 mali driver support capping the memory usage ?
I am looking at some of the memory stats for the mali driver and I see that the memory can grow till system runs out of memory:
cat gpu_memory
mali0 30117
kctx-0xe4bff000 29066 1876
kctx-0xe5b97000 144 1208
kctx-0xe9fba000 629 797
kctx-0xe3b92000 278 295
This is especially bad since this memory is not accounted as process memory.

It is linux (android), there are 2 sides of this: first the kernel driver allocated memory using a combination of gralloc/ion and second the process memory map from the dynamic lib. I am interested in the kernel memory usage, I can give you an example, candy crush uses about about 150MB worth of pages mapped to the process and another 120MB by the mali kernel driver. There are hacks to show the memory clubbed together (like dumpsys meminfo) but the linux kernel doesn't see those as together and can not reclaim or swap that mem. I am interested in anything that can reduce the memory consumption, even at the price of UX.
