Hello, There is a trouble on ARM with DMA allocations made by device drivers, the trouble is that DMA allocations are getting implicitly backed with IOMMU mapping by the driver core if IOMMU presents in a system and IOMMU could handle device. This is an undesired behaviour for drivers that manage IOMMU by themselves, like NVIDIA Tegra GPU driver. On arm32 the implicit backing happens if

This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. This version is mostly identical to v2 but fixes an important issue: the drvdata must be set to the drm_device for sysfs to work, so the platform device structure now includes the

This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. Thanks to the input received for v1, this version is more self-contained and shares less stuff between nouveau_drm and nouveau_platform. The major change is that nouveau_platform is now

This patch series is the final (?) step towards the initial support of GK20A, allowing it to be probed and used (currently at a very slow speed, and for offscreen rendering only) on the Jetson TK1 and Venice 2 boards. The main piece if the first patch which adds platform devices probing support to Nouveau. There are probably lots of things that need to be discussed about it, e.g.: * The way the

Also do you think you would be able to merge the driver (corresponding v4 patch follows) in the 3.2 merge window that seems to have just opened?

Hi, Generally the the imported buffers which has memory type TTM_PL_TT are mapped as small pages probably due to lack of big page allocation. But the platform device which also use memory type TTM_PL_TT, like GK20A, can *allocate* big page though the IOMMU hardware inside the SoC. This is a try to map the imported buffers as big pages in GMMU by the platform IOMMU. With some preparation work to

This is the next version of my patch series for teaching DRM how to automatically create debugfs nodes for drivers with MST topologies. This was originally intended just for nouveau, but has since been expanded to all DRM drivers.
