[PATCH 0/3] drm/tegra: Add support for fence FDs
...a handle returned as result of the job submission?
For the above it would suffice to add two additional flags:
#define DRM_TEGRA_SUBMIT_WAIT_SYNCOBJ (1 << 2)
#define DRM_TEGRA_SUBMIT_EMIT_SYNCOBJ (1 << 3)
which would even allow both to be combined:
DRM_TEGRA_SUBMIT_WAIT_SYNCOBJ | DRM_TEGRA_SUBMIT_EMIT_FENCE_FD
would allow the job to wait for an internal syncobj (defined by handle
in the fence member) and return a fence (as FD in the fence member) to
pass on to another process or driver as prefence.

Would be easy, if you are happy with the limitation of just a single
wait-fence.

[PATCH 0/3] drm/tegra: Add support for fence FDs
From: Thierry 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
