Hi Dave,
Just added new IPP driver since previous pull request.
We rewrited Exynos DRM IPP driver due to below limitations and issues, - Userspace API covers memory-2-memory picture operations together with CRTC writeback and duplicating features, which belongs to video plane. - Lack of support of the all required image formats (for example NV12 Samsung-tiled cannot be used due to lack of pixel format modifier support). - Userspace API designed only to mimic hardware behaviour, not easy to understand. - Lack of proper input validation in the core, drivers also didn't do that correctly, so it was possible to set incorrect parameters and easil trigger IOMMU fault or memory trash. - Drivers were partially disfunctional or supported only a subset of modes.
There is no user who uses old API excepting Tizen platform[1] we are developing, and we will update the platform with new version.
Sample applications for new version, https://www.spinics.net/lists/linux-samsung-soc/msg60498.html https://github.com/tobiasjakobi/libdrm/blob/ippv2/exynos/exynos_ipp.c
Please kindly let me know if there is any problem.
Thanks, Inki Dae

drm/exynos: Add driver for Exynos Scaler module (2017-11-09 19:59:22 +0900)
---------------------------------------------------------------- - Improved HDMI and Mixer drivers . It moves mode setup and plane update code to commit like other CRTC drivers . It makes mode commit to be called in enable callback only one time . some cleanup and fixup to HDMI and Mixer drivers. . It adds 1024x768, 1280x1024 and 1366x768 modes support - Added HDMI audio interface driver . As of now, HDMI audio worked on boards with external audio codec connected in parallel with the HDMI audio transmitter's I2S interface. This patch is required to support HDMI audio properly. - Remove old version of Exynos DRM IPP driver and add new version. - Convert each post processing driver - Rotator, GScaler and FIMC - to new API.
