Subject: [PATCHv9 00/10] ARM: DMA-mapping framework redesign
Date: Wed, 18 Apr 2012 15:44:02 +0200 [thread overview]
Message-ID: <1334756652-30830-1-git-send-email-m.szyprowski@samsung.com> (raw)
Hello,
This is a quick update on dma-mapping redesign patches for ARM. I did
some minor fixes suggested by Arnd and extended commit messages for a
few patches. Like the previous version, the patches have been rebased
onto latest Linux v3.4-rc3 which comes with dma_map_ops related
preparation changes.
The patches are also available on my git repository at:
git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git 3.4-rc3-arm-dma-v9
The code has been tested on Samsung Exynos4 'UniversalC210' and NURI
boards with IOMMU driver posted by KyongHo Cho. The integration patch
has been posted in the following thread:
