DESCRIPTION:Speakers: Danylo Piliaiev (Igalia S.L.)\nTurnip is a Vulkan dr
 iver for Adreno GPUs\, written by reverse engineering the hardware. We als
 o don’t yet have many real-world users running games\, but the driver is
  capable of running games that use D3D12\, VK\, D3D11\, and older APIs. In
  such an environment\, maintaining driver correctness while delivering per
 formance improvements is a challenge.\n\nAt previous XDCs\, I talked about
  how to debug GPU issues and how to improve the GPU debugging experience\;
  however\, the best way to do that is to avoid debugging issues altogether
 . Catching them early\, when changes are being written\, is much more prod
 uctive.\n\nI will talk about:\n- Using single frame game captures in CI to
  test correctness\;\n- Detecting performance regressions with the same CI 
 runs\;\n- Making detailed performance comparisons against the closed-sourc
 e driver.\n\nhttps://indico.freedesktop.org/event/10/contributions/409/

DESCRIPTION:Speakers: Heinrich Fink (Snap Inc.)\nXR compositors rely on ti
 mely execution of GPU workloads to apply a late-stage framebuffer update s
 hortly before scanout. This operation often contends with other concurrent
  rendering workloads occupying the GPU\, and its completion might get dela
 yed past its deadline\, resulting in undesired artefacts.\n\nA widely used
  solution to this problem is to apply some form of GPU-level preemption. H
 owever\, preemption latency still varies with the type of workload to pree
 mpt\, a risk of excessive delays of the time-sensitive workload remains.\n
 \nIn this talk we discuss a different approach: provided we have multiple 
 independent execution GPU cores available\, can we reserve a core for the 
 time-sensitive workload to execute independently of everything else? We pr
 esent a brief case study using the ARM Mali G610 GPU\, a four-core configu
 ration\, driven by the PanVK/panthor open-source Vulkan driver.\n\nhttps:/

DESCRIPTION:Speakers: Suraj Kandpal (Intel)\nWith the rapid proliferation 
 of high-quality digital media\, effective content protection mechanisms ha
 ve become essential to prevent unauthorized copying\, redistribution\, and
  piracy. This presentation explores the architecture and implementation of
  content protection (CP) technologies in the Linux graphics stack\, focusi
 ng primarily on High-bandwidth Digital Content Protection (HDCP) and Prote
 cted Audio Video Path (PAVP).\nWe begin by examining the motivations behin
 d content protection: protecting creators’ intellectual property and mee
 ting stringent compliance requirements imposed by content providers and li
 censing authorities. The talk outlines the historical limitations of HDCP 
 1.x—its reliance on aging cryptographic algorithms such as RC4\, limited
  interface support\, and vulnerability to reverse engineering—and descri
 bes how HDCP 2.x addresses these shortcomings through modern encryption (R
 SA\, AES)\, enhanced revocation mechanisms\, and expanded compatibility wi
 th newer interfaces like HDMI 2.0\, DisplayPort\, and USB Type-C.\nThe pre
 sentation then details how content protection flows from userspace to the 
 kernel driver. We cover how userspace software negotiates and sets content
  protection properties (CONTENT_PROTECTION and CONTENT_TYPE) via DRM/KMS A
 PIs\, and how kernel drivers enforce these policies\, maintain state trans
 itions\, and ensure authenticated link establishment between the GPU and d
 isplay sink. Special emphasis is placed on how HDCP is typically used only
  for external displays\, while PAVP provides hardware-protected sessions i
 nternally and can be sufficient for trusted embedded panels.\nAttendees wi
 ll gain insight into the specific driver responsibilities—such as signal
 ing userspace when protection states change—and the integration of HDCP 
 and PAVP to achieve a secure end-to-end content pipeline. The session will
  also discuss the practical challenges and trade-offs associated with impl
 ementing CP\, including usability\, latency\, power consumption\, and the 
 complexity of supporting multiple evolving standards in an open-source env
 ironment.\nThe presentation aims to provide developers\, driver maintainer
 s\, and architects with a clear understanding of the current state of cont
 ent protection on Linux\, the reasons behind specific design choices\, and
  the practical considerations when enabling CP in production systems.\n\nh

 RADV is the Mesa Vulkan driver for AMD GPUs. It started in 2016 as an expe
 riment for GCN 1. Now RADV supports the very latest GPUs and offers cuttin
 g-edge features such as ray tracing\, mesh shading\, DGC and more. We spea
 rheaded a custom compiler backend called ACO. Thanks to the ubiquity of Vu
 lkan on the Linux desktop\, today RADV is the most widely used open source
  Vulkan driver for gaming.\n\nAfter so many years of development\, it's ti
 me to ask\, are we there yet?\n\nThis talk presents the current direction 
 of RADV development\, as well as some of the experience we gained on the w
 ay. It's also a status update on what's been happening in RADV over the pa
 st couple of years.\n\nI'll show the latest developments\, how we maintain
  the code\, how we are endeavouring to share code with RadeonSI\, how we u
 se NIR to improve our compiler stack and how we've retire thousands of lin
 es of legacy code from both drivers. I'll also touch on the topics we're c
 urrently working on and the issues we still face.\n\nhttps://indico.freede

DESCRIPTION:Speakers: Connor Abbott (Valve)\, Rob Clark (Qualcomm)\nUntil 
 recently\, freedreno\, the upstream kernel driver for Qualcomm Adreno GPUs
 \, has been using the same legacy memory management paradigm as other upst
 ream DRM drivers. While this worked well for the gallium/GL driver\, it wa
 s a poor fit for Vulkan\, where memory is managed explicitly by the user\,
  resulting in unnecessary complexity and CPU overhead\, and it couldn't ha
 ndle the more sophisticated use-cases required by "sparse textures" that a
 re used by some of the latest games. In order to fix this we embarked on a
  major project across the entire stack to rewrite the internals of the ker
 nel driver to use the recently-upstreamed gpuvm subsystem\, expose a compl
 etely new "VM_BIND" uAPI for managing memory\, and take advantage of it in
  turnip\, the upstream Vulkan driver. This then finally allowed us to impl
 ement sparse textures in turnip. In this talk we'll go over the challenges
  of retrofitting VM_BIND into a mature production driver and dealing with 
 the quirks of sparse textures on Adreno.\n\nhttps://indico.freedesktop.org

DESCRIPTION:Speakers: Swati Sharma ()\, Nemesa Garg ()\, Adarsh GM ()\nIn 
 this talk\, we will present an adaptive sharpness filter implemented in th
 e Intel graphics display engine [1]\, designed to intelligently enhance im
 age clarity based on content characteristics. Unlike conventional sharpeni
 ng techniques that apply uniform enhancement\, our solution preserves visu
 al quality by adapting dynamically to scene details\, with minimal power a
 nd performance overhead.\nWe will begin with the motivation behind introdu
 cing this feature in the display engine\, followed by a deep dive into the
  kernel-level implementation and its architectural considerations. Next\, 
 we will discuss the validation methodology\, including our use of the IGT 
 GPU Tools framework and Chamelium-based testing [4] to ensure correctness 
 and robustness. Finally\, we will explore the current state of userspace i
 ntegration efforts in open-source compositors such as GNOME [2] and KDE (K
 Win) [3].\nAs part of the upstream journey\, we are currently facing two m
 ain challenges: acceptance of the proposed UAPI and gaining support for th
 e feature at the compositor level. This session aims to open up discussion
  around these issues and encourage collaboration. The implementation is av
 ailable in open source\, and we welcome contributions from the broader com
 munity to help drive this forward.\n\n[1] KMD: https://patchwork.freedeskt

 ges in modern graphics drivers is accessing resources that live outside th

  the interface between the shader and the rest of the API is still a chall
 enge.  OpenGL and Vulkan\, and D3D12 all have vastly different approaches 
 to solving this problem.  In this talk\, Faith will give an overview of re
 source mapping\, both from an API and a hardware perspective\, and talk ab
 out some of the ways that Vulkan has advanced in recent years to try and m

DESCRIPTION:Speakers: Philipp Stanner (Red Hat)\nAll GPU drivers need a lo
 ad balancing mechanism for submitting jobs (i.e.\, command buffers) to the
 ir GPU. The shared infrastructure for this in the Linux kernel's DRM subsy
 stem is the DRM GPU Scheduler. This component has accumulated a large numb
 er of problems over the course of a decade. The talk shall give an overvie
 w over the history of the scheduler and how the problems came to be. Moreo
 ver\, it shows which problems were solved during the last 12 months\, and 
 which still persist. This part of the talk will also serve as an RFC for h
 ow we as kernel developers can work towards avoiding the most significant 
 issues of the category the scheduler experienced.\n\nAnother important asp
 ect of the GPU Scheduler that shall be highlighted is the addition of supp
 ort for firmware scheduling: For GPUs whose firmware performs the actual s
 cheduling (instead of the kernel being responsible for that)\, the DRM GPU
  Scheduler is not an actual scheduler anymore\, but a mere load balancer. 
 This motivates the introduction of a new\, significantly simplified piece 
 of DRM infrastructure: the DRM Jobqueue. The Jobqueue is intended to serve
  as a simpler\, more robust replacement of the DRM GPU Scheduler. First in
 tended users are upcoming drivers such as Nova\, and\, possibly\, later al
 so existing users of the GPU Scheduler.\n\nhttps://indico.freedesktop.org/

DESCRIPTION:Speakers: Alyssa Ross ()\n[Spectrum](https://spectrum-os.org) 
 is a Linux-based desktop operating system which aims to provide improved s

 ivers where possible) into its own lightweight virtual machine\, while sti
 ll providing a integrated desktop system.  In contrast to previous virtual
 ization-based desktop compartmentalization efforts\, Spectrum takes an ups
 tream-first approach\, building on top of mechanisms like Wayland security
  contexts\, XDG Desktop Portals\, and virtio-gpu.  This talk is an overvie
 w of how various freedesktop.org interfaces\, including those which were n
 ot designed with virtualization in mind\, can be used to enable a much mor
 e cohesive and sustainable compartmentalized system than has been possible
  in the past\, and aims to start a discussion about how virtualization mig
 ht be further accommodated in freedesktop.org protocols and implementation

DESCRIPTION:Speakers: Erico Nunes ()\nNew Mesa drivers are starting to def
 ault to Vulkan-first (with OpenGL provided as a layer by Zink). One import
 ant part of enabling a new Vulkan driver is to enable WSI (Window System I
 ntegration) and support compositors through e.g. Wayland. The options to s
 upport this WSI development for new Vulkan-first drivers haven't been too 
 many or require significant enablement upfront\, so these platforms may si
 gnificantly delay being able to run a first Wayland compositor which can r
 un some simple Vulkan applications on a display.\nThe Weston Wayland compo
 sitor has been used for this purpose during enablement of OpenGL drivers a
 nd has useful features/backends to support that\, it would be great if Wes
 ton had a native Vulkan renderer with that use case in mind.\nWell\, now i
 t does! https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/167
 9\n\nThis talk aims to introduce the state and design choices of the Westo
 n Vulkan renderer\, bring up some of the current challenges\, and start a 
 discussion on its applications (Vulkan-first platforms\, development\, tes
 ting and CI for Vulkan drivers\, actually using it as a compositor\, etc).

DESCRIPTION:Speakers: Paul Kocialkowski (sys-base)\nNumerous chips still c
 ome with dedicated 2D hardware accelerators that are often not part of big
 ger gpu unit. These devices are usually very efficient for simple composit
 ing and transform works and can be useful to accelerate display compositin
 g or be used as part of multimedia pipelines.  They also typically offer l
 ow latencies and low power cost.\n\nUnfortunately they are mostly unsuppor
 ted in Linux and there is no standard userspace API and implementation to 
 leverage them. As of today\, most users looking to use these units are lef
 t with proprietary APIs and binary libraries.\n\nThis talk will present a 
 brief overview of 2d acceleration hardware\, exisiting proprietary APIs an
 d the current state of things in mainline Linux. Some thoughts and proposi
 tions to properly support these units will then be discussed.\n\nhttps://i

DESCRIPTION:Speakers: Shashank Sharma ()\nNow a days many consumer electro
 nics segments demand several display outputs coming out of a single Graphi
 cs card. Like modern Automotive infotainment segment demands 12-15 HDMI di
 splay outputs being driven from a single GPU\, so that they can be used to
  display navigation panel\, control panel\, mirrors\, multiple media playe
 rs and several independent status readers to show speedometer\, maps\, odo
 meters\, temperature\, music etc. But due to limited number (3-4) of displ
 ay pipelines available in its Display engine\, the GPU can only drive 3 or
  4 independent output displays per card\, which leaves a gap for a solutio
 n in this market.\n\nThe method proposeed here presents a unique method co
 mbining the synergy of SW and HW to solve this problem. The software creat
 es graphics superbuffers to encode multiple display outputs in a single la
 rge framebuffer\, and drives it in a single display pipeline by using GPU'
 s capacity to drive high resolutions and then uses a smart splitter HW at 
 the end of the display pipeline to splits and push these splitted buffers 
 into multiple display outputs.\n\nIf implemented precisely\, this method w
 ill allow a single GPU to drive 12-16 output displays.\n\nhttps://indico.f

DESCRIPTION:Speakers: Louis Chauvet ()\nAs a userspace developer\, creatin
 g graphical applications is a common task. While software and frameworks l
 ike Weston or Qt make it straightforward to display content on a screen\, 
 ensuring compatibility across various displays poses significant challenge
 s. Users may have different screen sizes\, resolutions\, and capabilities\
 , making comprehensive testing complex. How will your application perform 
 on a small screen? What about an extremely large one? How does it react to
  displays being connected/disconnected? Moreover\, if your application mus
 t run on diverse devices\, how will it leverage or adapt to varying hardwa
 re capabilities?\n\nVKMS addresses these challenges by enabling graphic te
 sting without the need for physical hardware. VKMS is a Linux kernel DRM d
 river that allows you to emulate a wide range of display configurations on
  any device. This talk will introduce VKMS\, highlight its current capabil
 ities\, demonstrate practical test examples\, and provide details on addit
 ional features we are currently working on upstreaming into VKMS.\n\nhttps
