Documentation: use a source-read extension for the index link boilerplate

2026-01-23T18:59:34+00:00

The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

gpu: nova-core: add initial documentation

2025-03-09T18:24:29+00:00

Add the initial documentation of the Nova project. The initial project documentation consists out of a brief introduction of the project, as well as project guidelines both general and nova-core specific and a task list for nova-core specifically. The task list is divided into tasks for general Rust infrastructure required by the project, tasks regarding GSP enablement and firmware abstraction, general GPU driver tasks as well as tasks related to external API design and test infrastructure.

drm: zynqmp_dp: Add debugfs interface for compliance testing

2024-10-30T12:21:07+00:00

Add a debugfs interface for exercising the various test modes supported by the DisplayPort controller. This allows performing compliance testing, or performing signal integrity measurements on a failing link. At the moment, we do not support sink-driven link quality testing, although such support would be fairly easy to add. Additionally, add some debugfs files for ignoring AUX errors and HPD events, as this can allow testing with equipment that cannot emulate a DPRX.

drm/xe: Introduce a new DRM driver for Intel GPUs

2023-12-12T19:05:48+00:00

Xe, is a new driver for Intel GPUs that supports both integrated and discrete platforms starting with Tiger Lake (first Intel Xe Architecture). The code is at a stage where it is already functional and has experimental support for multiple platforms starting from Tiger Lake, with initial support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan drivers), as well as in NEO (for OpenCL and Level0). The new Xe driver leverages a lot from i915. As for display, the intent is to share the display code with the i915 driver so that there is maximum reuse there. But it is not added in this patch. This initial work is a collaboration of many people and unfortunately the big squashed patch won't fully honor the proper credits. But let's get some git quick stats so we can at least try to preserve some of the credits: Co-developed-by: Matthew Brost Co-developed-by: Matthew Auld Co-developed-by: Matt Roper Co-developed-by: Thomas Hellström Co-developed-by: Francois Dugast Co-developed-by: Lucas De Marchi Co-developed-by: Maarten Lankhorst Co-developed-by: Philippe Lecluse Co-developed-by: Nirmoy Das Co-developed-by: Jani Nikula Co-developed-by: José Roberto de Souza Co-developed-by: Rodrigo Vivi Co-developed-by: Dave Airlie Co-developed-by: Faith Ekstrand Co-developed-by: Daniel Vetter Co-developed-by: Mauro Carvalho Chehab Signed-off-by: Rodrigo Vivi Signed-off-by: Matthew Brost
