drm/xe/debugfs: Update xe_tuning_dump signature

2025-09-30T08:21:26+00:00

Our debugfs helper xe_gt_debugfs_show_with_rpm() expects print() functions to return int. New signature allows us to drop wrapper. While around, print additional separation lines using puts() to avoid output with leading \n which might confuse some printers.

drm/xe: Add performance tunings to debugfs

2025-03-01T05:47:33+00:00

Add a list of active tunings to debugfs, analogous to the existing list of workarounds. Rationale being that it seems to make sense to either have both or none.

drm/xe: Fix application of LRC tunings

2023-12-19T23:29:06+00:00

LRC tunings were added after the gt ones and didn't add the call in xe_gt_record_default_lrcs() to process them like is done for workarounds. Add such a function and call it from xe_gt_record_default_lrcs(). Signed-off-by: Lucas De Marchi Reviewed-by: Matthew Auld Signed-off-by: Rodrigo Vivi

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
