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

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

Hi there, Resending these now that they've had some more polish and testing, and I heard that Ben's vacation is over :-) These patches work as a starting point for more explicit error mechanisms and better robustness. At the moment, when a job hangs or faults, it seems that nouveau doesn't quite know how to handle the situation and often results in a hang. Some of these situations

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

Hi folks, Currently, when the device is removed (or the driver is unbound) the nouveau_drm structure de-allocated. However, it's still accessible from and used by some DRM layer callbacks. For example, file handles can be closed after the device has been removed (physically or otherwise). This series converts the Nouveau device structure to be allocated and de-allocated with the
