Hi all, I have been removed previous branch and added new one with more cleanup. This time, the fence helper doesn't include user side interfaces and cache operation relevant codes anymore because not only we are not sure that coupling those two things, synchronizing caches and buffer access between CPU and CPU, CPU and DMA, and DMA and DMA with fences, in kernel side is a good idea yet but also existing codes for user side have problems with badly behaved or crashing userspace. So this could be more discussed later. The below is a new branch, https://git.kernel.org/cgit/linux/kernel/git/daeinki/drm-exynos.git/?h=dma-f ence-helper And fence helper codes, https://git.kernel.org/cgit/linux/kernel/git/daeinki/drm-exynos.git/commit/? h=dma-fence-helper&id=adcbc0fe7e285ce866e5816e5e21443dcce01005 And example codes for device driver, https://git.kernel.org/cgit/linux/kernel/git/daeinki/drm-exynos.git/commit/? h=dma-fence-helper&id=d2ce7af23835789602a99d0ccef1f53cdd5caaae I think the time is not yet ripe for RFC posting: maybe existing dma fence and reservation need more review and addition work. So I'd glad for somebody giving other opinions and advices in advance before RFC posting.
