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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Thierry Reding <treding@xxxxxxxxxx>

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:
