[PATCH 0/6] drm/nouveau: Support sync FDs and sync objects
From: Thierry Reding <treding at nvidia.com>
Hi,
This series implements a new IOCTL to submit push buffers that can
optionally return a sync FD or sync object to userspace. This is useful
in cases where userspace wants to synchronize operations between the GPU
and another driver (such as KMS for display). Among other things this
allows extensions such as eglDupNativeFenceFDANDROID to be

[RFC] Explicit synchronization for Nouveau
Hi guys,
I'd like to start a new thread about explicit fence synchronization. This time
with a Nouveau twist. :-)
First, let me define what I understand by implicit/explicit sync:
Implicit synchronization
* Fences are attached to buffers
* Kernel manages fences automatically based on buffer read/write access
Explicit synchronization
* Fences are passed around independently
* Kernel takes
