In this talk I'd like to show how to go beyond per-draw performance counters by using the thread tracing feature on AMD GPUs. This will include instruction-level shader profiling and high frequency streaming performance counters as well as a look at the impact of barriers and other serializing commands.
Memory encryption is an important part of content protection schemes like Widewine L1. This talk will delve into the details of TMZ (Trusted Memory Zone) on AMD GPUs touching on the software implementation details and hardware requirements and limitations that needed to be addressed to support this in the kernel, mesa, and userspace...
A quick talk to give an overview of GSoC/EVoC and XOrg's involvement therein.
Whether it is HPC or gaming, peer to peer DMA is an important part of improving IO throughput and performance on servers and workstations and yet, it has only recently become barely functional on Linux. This talk delves into the history of peer to peer DMA on Linux, why it is so challenging, what the current landscape looks like, and ways we can improve in the future.
A short status update what happens in etnaviv land right now. Would cover a quick recap about the history, current state, some CI news and whats worked on right now.
EXT_external_objects and EXT_external_objects_fd are groups of OpenGL
extensions that allow OpenGL and Vulkan interoperability. When enabled,
Vulkan allocated resources can be accessed and re-used by OpenGL. This
talk is about the implementation of the extensions in various drivers,
and some common interoperability use cases and examples that have been
added to piglit.
James Jones fron NVIDIA has presented a proposal a few years back to redesign the buffer allocation mechanisms on Linux (especially for GPUs, display devices, etc). However this is a pretty ambitious undertaking because it involves rewriting a big part of the graphics stack.
His proposal included several components. The recent work on...
In this presentation I will talk about graphics tracing and a collection of tools useful for profiling and trace analysis.
I will introduce gfx-pps, a project Collabora started working on this year, which provides some components that, in conjunction with Google's Perfetto, enable you to capture a trace and visualize GPU performance counters, or any kind of timeline, with a nice...
When it comes to the hardware acceleration on the RaspberryPi (or any other
board, really), we often talk about the video encoding/decoding. With the
modern ARM CPUs (with NEON support) and libraries (like libjpeg-turbo), usage
of the dedicated hardware components for images encoding/decoding becomes less
important. However, there is still low-end hardware on the market (like...
In this talk we are going over adriconf, where it all started and what is the current state of mesa driver configuration from a end user perspective.
We will also briefly talk about the MESA_query_driver extension and why we need it as well as future Vulkan extension/work on the configuration area.
Your secretary's yearly report on the state of the X.org Foundation. Expect updates on the freedeskoptop.org, internship and student programs, XDC, and more!
wlroots is a modular Wayland compositor library. This talk will give a sneak peak at the recent and upcoming architectural changes for the wlroots rendering and display pipeline to support features such as hardware planes, new renderers and explicit synchronization.
