From: Thierry Reding <treding at nvidia.com> This small series of patches implements support for waiting on and emitting fence FDs on kickoff. This enables explicit fencing and can be used for example to synchronize buffer accesses between the display engine and the GPU on Tegra. The first patch lays the groundwork by splitting up nouveau_fence_sync() to allow reuse. Patch 2 is where the

This series depends on the previously posted reservation api patches. 2 of them are not yet in for-next-fences branch of git://git.linaro.org/people/sumit.semwal/linux-3.x.git The missing patches are still in my vmwgfx_wip branch at git://people.freedesktop.org/~mlankhorst/linux All ttm drivers are converted to the fence api, fence_lock is removed and rcu is used in its place. qxl is the first

fence_is_signaled callback should support being run in atomic context, but not in irq context.

This series applies on top of the driver-core-next branch of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git Before converting ttm to the new fence interface I had to fix some drivers to require a reservation before poking with fence_obj. After flipping the switch RCU becomes available instead, and the extra reservations can be dropped again. :-) I've done at least basic

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
