[PATCH 1/3] gpu: host1x: Add support for DMA fences
From: Mikko Perttunen <mperttunen at nvidia.com>
Add an implementation of DMA fences backed by Host1x syncpoints,
an interface to specify a prefence for job submissions.
Before submission, prefences containing only Host1x syncpoints
are waited by pushing wait commands to CDMA, whereas other
fences are CPU-waited.

[PATCH 0/3] drm/tegra: Add support for fence FDs
...y Reding <treding at nvidia.com>
This set of patches adds support for fences to Tegra DRM and complements
the fence FD support for Nouveau. Technically this isn't necessary for a
fence-based synchronization loop with Nouveau because the KMS core takes
care of all that, but engines behind host1x can use the IOCTL extensions
provided here to emit fence FDs that in turn can be used to synchronize
their jobs with either the scanout engine or the GPU.
See the following link for the Nouveau fence FD support series:

IIRC the only way I've gotten Host1x to work on Tegra186 with IOMMU
enabled is doing the equivalent of this patch (or actually using the DMA
API, which may be possible but has some potential issues).
As you said, we don't have a limitation regarding the context bank or
similar - Host1x handles context switching by changing the...
