Hello -
This is a repeat of this question I put on the Tizen forum :
https://developer.tizen.org/forums/general-support/contiguous-memory-allocator-cma-support-non-ivi-tizen
At https://review.tizen.org/git/ I see this git repository :
profile/ivi/kernel-adaptation-intel-automotive.git
After I clone the repository I note these include files :
carlos@mypc:~/source/profile/ivi/kernel-adaptation-intel-automotive$ grep CMA
./arch/x86/include/asm/dma-contiguous.h ./include/asm-generic/dma-contiguous.h
./include/linux/dma-contiguous.h
./include/asm-generic/dma-contiguous.h:#ifdef CONFIG_CMA
./include/linux/dma-contiguous.h:#ifndef __LINUX_CMA_H
./include/linux/dma-contiguous.h:#define __LINUX_CMA_H
./include/linux/dma-contiguous.h: * The Contiguous Memory Allocator (CMA)
makes it possible to
./include/linux/dma-contiguous.h: * CMA tries to solve this issue by operating
on memory regions
./include/linux/dma-contiguous.h: * CMA should not be used by the device
drivers directly. It is
./include/linux/dma-contiguous.h:#ifdef CONFIG_CMA
./include/linux/dma-contiguous.h: * There is always at least global CMA area
and a few optional device
./include/linux/dma-contiguous.h:#define MAX_CMA_AREAS (1 + CONFIG_CMA_AREAS)
./include/linux/dma-contiguous.h:#define MAX_CMA_AREAS (0)
QUESTION: Is CMA planned for non-IVI Tizen?
Thank You,
Carlos
