From: Thierry Reding <treding@xxxxxxxxxx> Hi, this set of patches perform a bit of cleanup and extend support to the VDE implementation found on Tegra114 and Tegra124. This requires adding handling for a clock and a reset for the BSEV block that is separate from the main VDE block. The new VDE revision also supports reference picture marking, which requires that the BSEV writes out some related data to a memory location. Since the supported tiling layouts have been changed in Tegra124, which supports only block-linear and no pitch- linear layouts, a new way is added to request a specific layout for the decoded frames. Both of the above changes require breaking the ABI to accomodate for the new data in the custom IOCTL. Finally this set also adds support for dealing with an IOMMU, which makes it more convenient to deal with imported buffers since they no longer need to be physically contiguous. Userspace changes for the updated ABI are available here: https://cgit.freedesktop.org/~tagr/libvdpau-tegra/commit/ Mauro, I'm sending the device tree changes as part of the series for completeness, but I expect to pick those up into the Tegra tree once this has been reviewed and you've applied the driver changes.
