Hi all, After 5 years or so of intending to get round to this, finally the time comes! The changes themselves actualy turn out to be relatively mechanical; the bigger concern appears to be how to get everything merged across about 5 diffferent trees given the dependencies. I've lightly boot-tested things on Rockchip RK3288 and Exynos 4412 (Odroid-U3), to the degree that their display drivers should be using IOMMU-backed buffers and don't explode (the Odroid doesn't manage to send a working HDMI signal to the one monitor I have that it actually detects, but that's a pre-existing condition...) Confirmation that the Mediatek, OMAP and Tegra changes work will be most welcome. Patches are based on 5.9-rc1, branch available here: git://linux-arm.org/linux-rm arm/dma Robin.
