Making bare-metal testing accessible to every developer (xdc2021)


With Freedesktop's move to Gitlab every project not only got access to a lot of machine time, but they also got all the infrastructure to automate their runs, inspect the results, and provide automated testing reports of merge requests. This has led to a lot of projects adopting it to reduce regressions and maintenance costs to the point of almost bankrupting Freedesktop...

X.Org security BoF (xdc2021)


I'm going to present a summary of the last 10 years or so of participating to the moderation and animation of the xorg-security@ mailing lists. This is an opportunity for people interested in taking over this responsibility to have an insight of the kind of issues that are submitted and how we've been dealing with them. about this event: https://c3voc.de

Status of freedesktop.org gitlab/cloud hosting (xdc2021)


Last year, it was fires everywhere. This year? well, it was also the same, sort of. In this talk, we will see what steps we took to reduce further more our bill for our gitlab hosting. We will also tell some jokes like "oh, BTW, we almost lost all of our storage", or something like "oops, I killed the entire cluster". Oh the fun we had. So yes, this is basically the continuation of the talk I gave last year to present the new infrastructure and the roadmap we have for gitlab.freedesktop.org...

TTM conversion in i915 (xdc2021)


The purpose of TTM is to provide buffer object contents in memory where it is mappable by the CPU and GPU when needed, and also to allow overcommitting by means of swapping or eviction. This talk will cover the process of moving memory management in i915 kernel driver to TTM. about this event: https://c3voc.de

KWinFT's wlroots backend (xdc2021)


The [big change][1] in KWinFT this year is the replacement of all its own hardware backend plugins for its Wayland session with a single backend talking to wlroots. This talk goes into detail on: - reasons for this strategic move, - technical realization, - outcome with advantages and disadvantages, - long-term impact on the ecosystem.

Hostile Multi-Tenancy on a Single Commodity GPU: Can it be secure? (xdc2021)


While GPU multi-tenancy in the server world has grown rapidly, hostile multi-tenancy on single, commodity GPUs has been virtually unexplored. Existing multi-tenancy solutions for GPUs all fall short in at least one of the following areas: Minimizing attack surface, strongly isolating potentially hostile tenants, supporting consumer GPUs, and allowing parallel sharing of a single GPU between tenants...

Improving the Linux display stack reliability (xdc2021)


Due to its nature, the display stack can be hard to test. Indeed, the component we want to test often sends the pixels to an external display without any way to retrieve the image being output, let alone make sure it's correct. And while a human can perform some of those tests by looking at the screen, some issues can prove to be difficult to spot, such as colours being slightly off or pixels being offset. More complex tests can also be tedious to set up or hard to trigger...

Redefining the Future of Accelerator Computing with Level Zero (xdc2021)


Modern applications in areas like Machine Learning, Artificial Intelligence, and 3D Graphics, require a synergistic software/hardware ecosystem that allow developers to take full advantage of hardware accelerators. In this scenario, it is critical to have a low-level API that can easily support and adapt to any device, in order to minimize the impact in upper-levels of the software stack when exposing novel hardware capabilities to higher-level programming models and frameworks...

Enabling Level zero Sysman APIS for Tool developers to control the GPUs. (xdc2021)


We talk about a new programming interface “Sysman” which is part of level zero library. Sysman (System Resource Management) is used to monitor and control the power, frequency, temperature etc , of accelerator devices. Sysman is an API that will, • Enable HPC (High Performance Compute) GPU servers to optimize/track power, temperature ,utilization, memory bandwidth & scheduling of Intel discrete graphics cards for the kind of workloads that run in those environments...
