Some games are sta rting to use these APIs and some Mesa drivers have recently implemented su pport for related Vulkan extensions. This talk will quickly explain the ge neral concepts behind Device-Generated Commands and will provide a rough i dea of how these APIs look like in Vulkan.\n\nhttps://indico.freedesktop.o rg/event/6/contributions/299/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/299/ END:VEVENT BEGIN:VEVENT SUMMARY:Color operations for Linux color pipeline on AMD devices DTSTART;VALUE=DATE-TIME:20241009T161000Z DTEND;VALUE=DATE-TIME:20241009T163000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-293@indico.freedesktop.org DESCRIPTION:Speakers: Alex Hung ()\nLinux color pipeline is a prescriptive API to address hardware color management that differs from one hardware t o another. Each device driver passes userspace a pipeline consisting of a chain of unique and static colorops that map to color management blocks in hardware. \n\nThis talk shares an overview of a color pipeline and the de finitions of colorops for 1D curve/LUTs\, 3D LUTs and matrices for Linux. The work includes kernel implementation of colorops specific to AMD device s\, and IGT tests that demonstrates how an userspace application communica tes to Linux kernel by new APIs and drm_colorops structures.\n\nhttps://in dico.freedesktop.org/event/6/contributions/293/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/293/ END:VEVENT BEGIN:VEVENT SUMMARY:Input observers beyond focus DTSTART;VALUE=DATE-TIME:20241010T210500Z DTEND;VALUE=DATE-TIME:20241010T211000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-331@indico.freedesktop.org DESCRIPTION:Speakers: Philipp Kaeser (Google)\nRationale and use-cases for observing & receiving (some) input device actions also for non-focussed s urfaces.\n\nhttps://indico.freedesktop.org/event/6/contributions/331/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/331/ END:VEVENT BEGIN:VEVENT SUMMARY:XDC 2024 Closing session DTSTART;VALUE=DATE-TIME:20241011T212500Z DTEND;VALUE=DATE-TIME:20241011T213000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-399@indico.freedesktop.org DESCRIPTION:Speakers: Mark Filion (Collabora)\nhttps://indico.freedesktop. org/event/6/contributions/399/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/399/ END:VEVENT BEGIN:VEVENT SUMMARY:Panfrost update DTSTART;VALUE=DATE-TIME:20241010T143000Z DTEND;VALUE=DATE-TIME:20241010T145000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-305@indico.freedesktop.org DESCRIPTION:Speakers: Erik Faye-Lund (Collabora)\, Boris Brezillon (Collab ora)\nThis talk will cover what's happened in the word of Panfrost in the last year.

However\, graphic usage is not enough for mode rn requirement of GPU virtualization. Because AI and compute are more and more popular recently\, and the community also wants to have a way to supp ort compute virtualization on general GPU devices. \nAMD provided an open source stack named ROCm[2] to support machine learning\, coupled with bein g inspired by the idea of virtio native context. Then we dig out a solutio n to use Thunk (libhsakmt) API forwarding [3] via virtio-gpu to implement ROCm support on virtual machine and add virtio-gpu support into ROCm runti me as another GPU backend. With this way\, we can have a prototype to impl ement GPU compute virtualization with virtio.\nOpenCL is the first step th at we step in ROCm virtualization with virtio-gpu. This talk will provide an overview of AMDs experiences enabling compute virtualization with OpenC L over ROCm native context approach.\n\nReference:\n[1] https://indico.fre edesktop.org/event/4/contributions/216/\n[2] https://github.com/ROCm\n[3] https://gitlab.freedesktop.org/virgl/virglrenderer/-/merge_requests/1370\n \nhttps://indico.freedesktop.org/event/6/contributions/285/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/285/ END:VEVENT BEGIN:VEVENT SUMMARY:EBC - A new backend compiler for etnaviv DTSTART;VALUE=DATE-TIME:20241009T180500Z DTEND;VALUE=DATE-TIME:20241009T185000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-290@indico.freedesktop.org DESCRIPTION:Speakers: Christian Gmeiner ()\nAn efficient and flexible comp iler backend is crucial for performance and adaptability.

Several newe r notebook designs include dynamic display mux hardware\, which enables sw itching between GPUs while the system is actively running and displaying c ontent. Investigation into implementing support for dynamic mux switches h as highlighted limitations in existing Linux software infrastructure\, suc h as vga-switcheroo\, which prevent this hardware from being used to its f ullest potential.\n\nThis talk will present an overview of dynamic display mux hardware and the use cases which it makes possible\, review existing proposals for extending DRM-KMS to support dynamic mux switching\, and pro vide a high-level outline for how display servers and compositors would ne ed to be updated to take advantage of dynamic mux functionality once it's available in the kernel.\n\nhttps://indico.freedesktop.org/event/6/contrib utions/297/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/297/ END:VEVENT BEGIN:VEVENT SUMMARY:io_uring for DRM DTSTART;VALUE=DATE-TIME:20241010T180500Z DTEND;VALUE=DATE-TIME:20241010T182500Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-309@indico.freedesktop.org DESCRIPTION:Speakers: Liviu Dudau (Arm Ltd)\nModern GPUs are moving more f unctionality into firmware in order to allow for user space to submit jobs directly and gain additional performance from that.\n\nDRM framework for rendering nodes assumes that the kernel driver is in charge all the time a nd job submissions are only happening in kernel context.\n\nio_uring is a mechanism inside the kernel that allows for asynchronously queuing request s from userspace and let them be handled by the kernel driver(s) in a batc hed mode. Adopting this (or a very similar) mechanism in DRM would allow u s to gain the benefits of reduced context switching between userspace apps and kernel while keeping the kernel driver(s) for GPU(s) in charge of act ual job submissions.\n\nI am looking at gathering feedback on the idea and on why it might not be appropriate to add support for io_uring in DRM. We know that io_uring had its fair share of security issues and that Android for example disables it completely\, but there are other aspects that nee d to be discussed like user space implementing a job scheduling on its own \, or lack of a need for job scheduling at all as firmware might be comple tely in charge of that.\n\nhttps://indico.freedesktop.org/event/6/contribu tions/309/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/309/ END:VEVENT BEGIN:VEVENT SUMMARY:A bug's life DTSTART;VALUE=DATE-TIME:20241010T152000Z DTEND;VALUE=DATE-TIME:20241010T160500Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-314@indico.freedesktop.org DESCRIPTION:Speakers: David Heidelberg ()\, Erico Nunes ()\nLet me tell yo u a story of a bug affecting larger adoption of EGL standart\, which lived for more than 11 years in Mesa3D.\n\nThe journey to fix this bug involved many people\, a lot of code\, some CI testing\, a new display extension\, and many sleepless nights.\n\nThis talk aims to illustrate\, what can be done with open-source drivers and CI infrastructure which would never be p ossible achieve with a closed-source proprietary driver.\n\nhttps://indico .freedesktop.org/event/6/contributions/314/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/314/ END:VEVENT BEGIN:VEVENT SUMMARY:Wednesday Opening Session DTSTART;VALUE=DATE-TIME:20241009T130000Z DTEND;VALUE=DATE-TIME:20241009T131000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-380@indico.freedesktop.org DESCRIPTION:Speakers: Mark Filion (Collabora)\nWednesday Opening Session\n \nhttps://indico.freedesktop.org/event/6/contributions/380/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/380/ END:VEVENT BEGIN:VEVENT SUMMARY:Enhancements to the Raspberry Pi GPU driver stack.

Together with the audience\, we will assess if there's a desire to move towards a solution\, and if so continu e with a workshop on the third day of the conference.\n\nhttps://indico.fr eedesktop.org/event/6/contributions/308/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/308/ END:VEVENT BEGIN:VEVENT SUMMARY:Vulkan for Wayland Compositors: the new best choice?

This talk will cover multi-GPU chall enges I've encountered during recent compositor work\, explain why Vulkan' s device-aware API is a good match\, demonstrate some unique asynchronous copy logic made possible by Vulkan\, and go over why EGL can't be extended with similar features. Vulkan isn't a silver bullet\, but OpenGL isn't th e obvious choice it once was. The goal is to promote discussion about and further development of Vulkan-based compositors and infrastructure.\n\nhtt ps://indico.freedesktop.org/event/6/contributions/288/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/288/ END:VEVENT BEGIN:VEVENT SUMMARY:State of the X.Org Foundation (Room AB) DTSTART;VALUE=DATE-TIME:20241011T210000Z DTEND;VALUE=DATE-TIME:20241011T211000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-312@indico.freedesktop.org DESCRIPTION:Speakers: Lyude Paul (Red Hat)\nState of the X.Org Foundation\ n\nhttps://indico.freedesktop.org/event/6/contributions/312/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/312/ END:VEVENT BEGIN:VEVENT SUMMARY:Creating a database of games using specific vulkan extensions DTSTART;VALUE=DATE-TIME:20241010T212000Z DTEND;VALUE=DATE-TIME:20241010T212500Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-313@indico.freedesktop.org DESCRIPTION:Speakers: Thomas Andersen ()\nWhen implementing vulkan extensi ons it is nice to know which games are using a specific extension. Smoke t esting real world users of the extension can be a good addition to running the cts.\n\nI have started working on a vulkan layer that tries to detect when an extension is being used. This layer can be used to populate a dat abase of users of each individual extension.\n\nThis talk will be a quick status of the project and a call for others to participate by sending in m ore entries to the database.\n\nhttps://indico.freedesktop.org/event/6/con tributions/313/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/313/ END:VEVENT BEGIN:VEVENT SUMMARY:Wayland DRM Lease Protocol: Impacts on XR DTSTART;VALUE=DATE-TIME:20241010T213000Z DTEND;VALUE=DATE-TIME:20241010T213500Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-384@indico.freedesktop.org DESCRIPTION:Speakers: Frederic Plourde (Collabora ltd.)\nThis lightning ta lk will provide a brief overview of the latest developments in the Wayland DRM Lease protocol and highlight the immediate benefits it has brought to Monado\, th Open-Source OpenXR runtime.\n\nhttps://indico.freedesktop.org /event/6/contributions/384/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/384/ END:VEVENT BEGIN:VEVENT SUMMARY:How do you debug and triage AMD display driver issues?

In this presentatio n\, I want to equip users and developers with debug techniques (for AMD dr ivers) to help them determine if an issue is really a display problem by s haring some ways to interpret debug logs. I will also show how to narrow i ssues down to some parts of the source code. At the end of the presentatio n\, I hope the listener can use some of the AMD debugs and test tools and know where to check more about display documentation.\n\nSummary of the to pics:\n\n - Display code overview.\n - Check if an issue is a display prob lem or not.\n - Provide details about AMD logs (Dmesg\, DTN\, and UMR regi sters).\n - Some specific issues (hard hang\, MPO\, Power issues).\n - IGT .\n - Report bugs and how to contribute.\n\nhttps://indico.freedesktop.org /event/6/contributions/303/ LOCATION: URL:https://indico.freedesktop.org/event/6/contributions/303/ END:VEVENT BEGIN:VEVENT SUMMARY:Ray tracing for Adreno GPUs on Turnip DTSTART;VALUE=DATE-TIME:20241009T131500Z DTEND;VALUE=DATE-TIME:20241009T140000Z DTSTAMP;VALUE=DATE-TIME:20260510T213030Z UID:indico-contribution-6-302@indico.freedesktop.org DESCRIPTION:Speakers: Connor Abbott (Valve)\nTurnip is the fourth Vulkan d river in Mesa to gain support for ray tracing acceleration\, after anv\, r adv\, and lavapipe\, using the Ray Tracing Unit introduced by Qualcomm on Snapdragon 8 Gen 2.
