Hello, To help everyone in testing and adapting our patches for his hardware platform I've rebased our patches onto the latest v3.2 Linux kernel and prepared a few GIT branches in our public repository. These branches contain our memory management related patches posted in the following threads: "[PATCHv18 0/11] Contiguous Memory Allocator": http://www.spinics.net/lists/linux-mm/msg28125.html later called CMAv18, "[PATCH 00/14] DMA-mapping framework redesign preparation": http://www.spinics.net/lists/linux-sh/msg09777.html and "[PATCH 0/8 v4] ARM: DMA-mapping framework redesign": http://www.spinics.net/lists/arm-kernel/msg151147.html with the following update: http://www.spinics.net/lists/arm-kernel/msg154889.html later called DMAv5. These branches are available in our public GIT repository: git://git.infradead.org/users/kmpark/linux-samsung http://git.infradead.org/users/kmpark/linux-samsung/ The following branches are available: 1) 3.2-cma-v18 Vanilla Linux v3.2 with fixed CMA v18 patches (first patch replaced with the one from v17 to fix SMP issues, see the respective thread). 2) 3.2-dma-v5 Vanilla Linux v3.2 + iommu/next (IOMMU maintainer's patches) branch with DMA-preparation and DMA-mapping framework redesign patches. 3) 3.2-cma-v18-dma-v5 Previous two branches merged together (DMA-mapping on top of CMA) 4) 3.2-cma-v18-dma-v5-exynos Previous branch rebased on top of iommu/next + kgene/for-next (Samsung SoC platform maintainer's patches) with new Exynos4 IOMMU driver by KyongHo Cho and relevant glue code. 5) 3.2-dma-v5-exynos Branch from point 2 rebased on top of iommu/next + kgene/for-next (Samsung SoC maintainer's patches) with new Exynos4 IOMMU driver by KyongHo Cho and relevant glue code. I hope everyone will find a branch that suits his needs. :) Best regards -- Marek Szyprowski Samsung Poland R&D Center
