Zink is a work-in-progress Mesa Gallium driver that implements OpenGL on top of Vulkan. This talk will discuss why and how, and give an update on what's happened in Zink recently.
3D graphics with new hardware designs and APIs (such as Vulkan) are evolving rapidly. At the same time, windowing systems evolve with new protocols, use-cases, formats, synchronization mechanisms and so on. To effectively support all this GPU drivers separate the implementation of Windowing System Integration (WSI) from the Core 3D rendering.
In Vulkan, WSI is implemented through...
Radv (the radeon vulkan driver) has for a long time used LLVM as the
shader compiler backend. However, LLVM has a number of issues which
led us to develop an alternative shader compiler that strongly leans
on the shared nir intermediate language. This new compiler is showing
significant gains for compile time as well as runtime performance.
We will talk about our pain points with LLVM and...
In this talk, I will briefly describe my contributions as an outreachy round 15 intern. Broadly, I worked on refactoring code in the tinydrm subsystem. Specifically, I refactored the backlight and the spi helper functions.
The Khronos Group industry consortium has created and evolved many key graphics open standards such as OpenGL and Vulkan – and strongly supports their use in open source platforms. Come and hear about the latest Khronos initiatives and roadmap updates, and participate in an AMA session with Neil Trevett, Khronos President.
VR took off for the consumer with the release of Oculus consumer hardware. But the hardware lacked open source drivers and Linux support in general. The OpenHMD project was created to solve this issue. The consumer VR space has now grown from a kickstarter campaign into a large industry. But this growth has its down sides, multiple companies have their own APIs competing. Luckily these...
While investigating a performance issue with the F1 2017 game benchmark, we identified some bottlenecks related to how ttm and amdgpu do buffer validation and LRU handling. This ultimately lead to a major redesign of how we handle buffer migration. This talk describes process that we took to identify and fix the bottleneck and what we learned along the way.

Lima is an open source graphics driver which supports Mali 400/450 embedded GPUs from ARM via reverse engineering.
Recently, after many years since the beginning of the reverse engineering efforts on these devices, the lima driver has been finally upstreamed in both mesa and linux kernel counterparts.
This talk will cover some information about the target GPUs and implementation details of the...
Ever seen a true 33 million pixel 8K display? The maximum display link bandwidth available with DisplayPort’s highest bit rate of 8.1 Gbps/lane limits the resolution to 5K@60 over a single DP connector. Hence the only true 8K displays allowing upto full 60 frames per second are the tiled displays enabled using 2 DP connectors running at their highest bit rate across 2 CRTCs in the display...
Avoiding regressions in the input stack is hard. Ideally, every commit and the ones before it are tested against every possible device. But the universe hasn't seen it fit to provide us with an army of people to test devices, infinite resources, or even a lot of time to spare. Pity, that, really. But we do have a computer, so that's a start.
In this talk we show how we moved from basically no...
Thousands of moons ago, an obscure magical art developed by the Magic Resistance beneath the disquieting tides of the Magilectric Revolution: reverse-engineering... Some refuse to acknowledge its existence. Some mistakenly believe it a form of witchcraft or dark magic, entranced by its binary spells and shadowy hexes. The outer world rarely catches more than a glimpse of these powerful mages,...
