In the open-source world it is hard to get usage data back from users to choose which bug to prioritize. Also\, othe r developers are worried about their use cases and they don't care much if they broke yours (or maybe they just don't have the hardware to test it). Annoying\, isn't it?\n\nIn this talk we will check the benefits of pre-me rge tests\, what Marge bot is and how the Marge workflow is working well w ith Mesa3D project\, avoiding regressions to even being accepted and incre asing your confidence to the community.\n\nhttps://indico.freedesktop.org/ event/4/contributions/201/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/201/ END:VEVENT BEGIN:VEVENT SUMMARY:The case for an "icon" protocol DTSTART;VALUE=DATE-TIME:20231019T143000Z DTEND;VALUE=DATE-TIME:20231019T143500Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-192@indico.freedesktop.org DESCRIPTION:Speakers: Philipp Kaeser (Google)\nMigrating to Wayland also m eans to bid farewell to X11 Window Manager features that were popular in a few niches. Among them: The ability to set WM hints for an icon window.\n \nThis talk will present a brief recap on what this feature was used for\, sketch a proposal for a Wayland protocol for this use-case. Including a s hort demonstration of a prototype implementation in protocol and composito r.\n\nhttps://indico.freedesktop.org/event/4/contributions/192/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/192/ END:VEVENT BEGIN:VEVENT SUMMARY:To crash or not to crash: if you do\, at least recover fast!

Piccoli (Igalia)\nWhat could be possibl y worse that an almost unbeatable boss in a game or a tough maze that cons ume hours of gameplay with not much progress? How about a Linux kernel cra sh that makes you lose all the game progress with no apparent reason or fe edback?\n\nThough rare\, it is a real possibility that would make gamers q uite annoyed\, given that Linux is used more and more as a platform for pl aying games.\nSome technologies are available to collect logs and feedback the user in case such disastrous events happen\, mostly related with kern el crashes handling mechanisms. The main ones available are kdump and psto re\, but still there are work to be done in this area...\n\nIn this talk w e're going to present the basics about kernel crash handling\, like how a kernel panic might happen\, how to deal with that (with an overall discuss ion about kdump and pstore techs) and the kdumpst tool\, developed special ly to deal with this situation on Steam Deck (and generically on Arch Linu x)\; also we're gonna discuss some missing pieces / ideas to make it even less likely gamers need to complain that their device just got hang for no reason!\n\nhttps://indico.freedesktop.org/event/4/contributions/196/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/196/ END:VEVENT BEGIN:VEVENT SUMMARY:Being a Mesa release maintainer DTSTART;VALUE=DATE-TIME:20231019T144500Z DTEND;VALUE=DATE-TIME:20231019T145000Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-277@indico.freedesktop.org DESCRIPTION:Speakers: Eric Engestrom (Igalia / Mesa)\nQuick presentation o f what being a Mesa release maintainer entails\, with a call for volunteer s to reach out.\n\nhttps://indico.freedesktop.org/event/4/contributions/27 7/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/277/ END:VEVENT BEGIN:VEVENT SUMMARY:Focus on exciting development\, delegate tedious dependencies upda te DTSTART;VALUE=DATE-TIME:20231019T144000Z DTEND;VALUE=DATE-TIME:20231019T144500Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-214@indico.freedesktop.org DESCRIPTION:Speakers: Sergi Blanch Torné (Collabora)\nWhoops! There is a reminder to check your project's dependencies and update the revisions use d. Oof\, again we need to deal with job failures caused by changes made lo ng ago. You tell yourself it's something you should do more often\, but mo nitoring those dependencies is tedious. \n\nContinuous Integration is here to help us during development. We have automated the testing process\, so we can handle a test-driven design. But still\, some tasks interrupt the genuine challenges that need to be solved.\n\nWe would like to propose to you a solution to do this automatically: it is called `ci-uprev`. It can g enerate a proposal merge request when a new revision of the dependency can be used. If there are further problems than the updated expectations\, it can generate an issue with the information. The information is fresh and comes from recent changes\, so the people around still remember why they w ere required.\n\nBut what if there is some information in the jobs pipelin e that you have to browse individually? Uprev also needed that functionali ty so we created a tool called `ci-collate`. It allows you to define which jobs are interesting for you\, and generates a JSON structure detailing w hat all those jobs have.\n\nA practical application for this is the "night ly runs"\, where we do more extensive tests in Mesa than what we can do in the "pre-merge". If there are some expectations to update\, you can have a patch (or even a merge request) based on the results of your pipeline. G et it automatically\; you can use cron or launch it from your console.\n\n https://indico.freedesktop.org/event/4/contributions/214/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/214/ END:VEVENT BEGIN:VEVENT SUMMARY:Vivante NPU driver DTSTART;VALUE=DATE-TIME:20231019T145000Z DTEND;VALUE=DATE-TIME:20231019T145500Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-278@indico.freedesktop.org DESCRIPTION:Speakers: Tomeu Vizoso (Independent contractor)\nQuick summary of the current status and plans for the future\, for this and for similar IP.\n\nhttps://indico.freedesktop.org/event/4/contributions/278/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/278/ END:VEVENT BEGIN:VEVENT SUMMARY:The WayLand Conformance Suite (WLCS) DTSTART;VALUE=DATE-TIME:20231019T145500Z DTEND;VALUE=DATE-TIME:20231019T150000Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-279@indico.freedesktop.org DESCRIPTION:Speakers: Michał Sawicz (Canonical)\nA collection of integrat ion tests designed to ensure compositors' adherence to\, and agreement on the interpretation of\, the Wayland protocol and extensions.\n\nhttps://in dico.freedesktop.org/event/4/contributions/279/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/279/ END:VEVENT BEGIN:VEVENT SUMMARY:dGPU prime on VM DTSTART;VALUE=DATE-TIME:20231019T140500Z DTEND;VALUE=DATE-TIME:20231019T141000Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-189@indico.freedesktop.org DESCRIPTION:Speakers: Julia Zhang ()\nThe dGPU prime feature allows an int egrated GPU (iGPU) to display output data rendered by a discrete GPU(dGPU) . This is a collection of features in the Linux kernel[1]\, mesa[2] and va rious drivers under Linux system. The dGPU exports it's render buffer to i GPU so that iGPU can display it. This allows switching between iGPU and dG PU to handle more use cases requiring different levels of performance. Usu ally on bare metal\, iGPU and dGPU would use native drivers that support d ma-buf operations so this feature works fine. But on XEN guest VM\, the iG PU is using the virtio-gpu driver and the passthrough dGPU is using a nati ve driver\, so the iGPU cannot import the output data that rendered by the passthrough dGPU directly. This talk introduces our design and implementa tion of the dGPU prime feature on XEN guest VMs.It creates the display buf fer on the iGPU and lets the passthrough dGPU import it as linear buffer a nd blit the rendered data to it for display. With this\, we can now run ap plications which require high performance on the passthrough dGPU and disp lay on the iGPU in a XEN guest VM.\n\nReferences: \n[1] https://lore.kerne l.org/dri-devel/20230705035622.2841499-1-julia.zhang@amd.com/\n[2] https:/ /gitlab.freedesktop.org/mesa/mesa/-/merge_requests/23896\n\nhttps://indico .freedesktop.org/event/4/contributions/189/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/189/ END:VEVENT BEGIN:VEVENT SUMMARY:KMS Color Workshop Report DTSTART;VALUE=DATE-TIME:20231019T150000Z DTEND;VALUE=DATE-TIME:20231019T150500Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-280@indico.freedesktop.org DESCRIPTION:Speakers: Melissa Wen (Igalia)\nI brief summary of the discuss ions that happened in the KMS Color Management Workshop.\n\nhttps://indico .freedesktop.org/event/4/contributions/280/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/280/ END:VEVENT BEGIN:VEVENT SUMMARY:Road to HDR10 on ChromeOS DTSTART;VALUE=DATE-TIME:20231019T150500Z DTEND;VALUE=DATE-TIME:20231019T151000Z DTSTAMP;VALUE=DATE-TIME:20260716T231427Z UID:indico-contribution-26-281@indico.freedesktop.org DESCRIPTION:Speakers: Sasha McIntosh (Google)\nCurrently CrOS supports a c ustom format for HDR content.

AVC and HEVC are shipping with goo d support for decode\, and nascent encode support. AV1 and VP9 are in the works.\n\nWhile several APIs exist amid the convenience/control/portabilit y tradeoff\, the Vulkan extension exposes a much greater level of fine-gra ined control\, portability and tight-integration that none of the existing solutions offer\, at the expense of convenience.\n\nIn this talk we will very briefly explore the API\, cover the recent developments of the extens ion\, and discuss plans for future work. This talk will provide background information for anyone interested in integrating codec acceleration withi n their application.\n\nhttps://indico.freedesktop.org/event/4/contributio ns/188/ LOCATION:Palexco URL:https://indico.freedesktop.org/event/4/contributions/188/ END:VEVENT END:VCALENDAR
