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

Riley (CCed) and I will be at Plumbers in a couple weeks. There is a session on sync planned in the Android track, and of course we'll be available to chat.

Hello everyone, GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support for it, based on a rework of the already-supported GK20A. It also introduces support for NVIDIA-provided firmware files, which is why I have added a few NVIDIA people who are relevant to this discussion. The first patch adds support for loading the FECS and GPCCS firmwares from firmware files

Second version of this patchset. Not many changes since first version - I hope this means the changes are not too controversial. Changes since v1: - Removed lookup for previous FW files in "nouveau/" - Went back to using request_firmware() since we only try to load one file Original cover letter follows: GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support

Allow user space to provide an explicit sync fence fd when exporting a dma-buf from gem handle. The fence will be stored as the explicit fence to the reservation object.

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

Modify sync_fence_create to accept an array of 'struct fence' objects. This will allow drm drivers to create sync_fence objects and pass sync fd's between user space with minimal modifications, without ever creating sync_timeline or sync_pt objects, and without implementing the sync_timeline_ops interface. Modify the sync driver debug code to not assume that every 'struct

A naive question from someone who knows nothing of icmd or bundles... Would it be better to wait for both bits to become 0 (I.e. 0x6)?

Here are a few small fixes for issues we found while implementing support for GM20B. The first two are specific to Tegra/GK20A, but the last 3 patches may have a broader (hopefully beneficial) effect. Note that the newly introduced gf100_gr_wait_idle() function on patch 5/5 is exported on purpose. GK20A and GM20B drivers will soon make use of it. Ben, since you seemed to like these changes, a

From: Thierry Reding <treding at nvidia.com> Add a new nouveau_pushbuf_kick_fence() function that takes and emits a sync fence FD. The fence FD can be waited on, or merged with other fence FDs, or passed back to the kernel as a prerequisite for a subsequent HW operation.

One of my users complained that his Win2kSP2 complains that his password Is going to expire in 8 days. A while ago we changed from Win2k domain to a Samba 2.2.3a controlled domain. How do I disable the password expiration? I read the man pages and searched Google but couldn't find any hints about the issue. It almos seems like this expiration thing should not be happening at all...?

Hi all, I would like to monitor the power consumption of my server. What I am looking for is: * a simple monitoring device that would measure the power consumption of 1 server * a way to get the consumption reading from that device to my centos server (via usb / wlan / whatever works) Any suggestions?
