[PATCH v7 0/3] Add CMA heap for ION memory manager

by benjamin.gaignard＠linaro.org

From: Benjamin Gaignard <benjamin.gaignard(a)linaro.org> The goal of those patches is to allow ION clients (drivers or userland applications) to use Contiguous Memory Allocator (CMA). To get more info about CMA: http://lists.linaro.org/pipermail/linaro-mm-sig/2012-February/001328.html patches version 7: - rebased on Android kernel - fix ion Makefile - add ion_cma_map_kernel function - remove CONFIG_CMA compilation flags from ion_heap.c patches version 6: - add private field in ion_platform_heap to pass the device linked with CMA. - rework CMA heap to use private field. - prepare CMA heap for incoming dma_common_get_sgtable function http://lists.linaro.org/pipermail/linaro-mm-sig/2012-June/002109.html - simplify ion-ux500 driver. patches version 5: - port patches on android kernel 3.4 where ION use dmabuf - add ion_cma_heap_map_dma and ion_cma_heap_unmap_dma functions patches version 4: - add ION_HEAP_TYPE_DMA heap type in ion_heap_type enum. - CMA heap is now a "native" ION heap. - add ion_heap_create_full function to keep backward compatibilty. - clean up included files in CMA heap - ux500-ion is using ion_heap_create_full instead of ion_heap_create patches version 3: - add a private field in ion_heap structure instead of expose ion_device structure to all heaps - ion_cma_heap is no more a platform driver - ion_cma_heap use ion_heap private field to store the device pointer and make the link with reserved CMA regions - provide ux500-ion driver and configuration file for snowball board to give an example of how use CMA heaps patches version 2: - fix comments done by Andy Green Benjamin Gaignard (3): gpu: ion: fix ion_platform_data definition gpu: ion: add private field in ion_heap and ion_platform_heap structure gpu: ion: add CMA heap drivers/gpu/ion/Kconfig | 5 ++ drivers/gpu/ion/Makefile | 1 + drivers/gpu/ion/ion_cma_heap.c | 187 ++++++++++++++++++++++++++++++++++++++++ drivers/gpu/ion/ion_heap.c | 7 ++ drivers/gpu/ion/ion_priv.h | 16 ++++ include/linux/ion.h | 7 +- 6 files changed, 222 insertions(+), 1 deletion(-) create mode 100644 drivers/gpu/ion/ion_cma_heap.c -- 1.7.10
