Hello, I'm using source from Android4sam of linux kernel, I have made some modification for my board,
I'm using a 800x480 display with 24 bpp.
So framebuffer is 115.2Kib and for android is 4 time greater.

My problem is that dma_alloc_coherent fail with error -12.

The CONSISTENT_DMA_SIZE is SZ_16M

Someone could help me.

Thanks

Michele
