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

drm/mcde: Add new driver for ST-Ericsson MCDE

2019-05-24T15:00:13+00:00

This adds a new DRM driver for the ST-Ericsson Multi Channel Display Engine, MCDE display controller. This hardware has three independent DSI hosts and can composit and display several memory buffers onto an LCD display. It was developed for several years inside of ST-Ericsson and shipped with a few million mobile phones from Sony and Samsung, as well as with the Snowball community development board. The driver is currently pretty rudimentary but supports a simple framebuffer so we can get penguins and graphics when using these SoCs.
