2024-01-11drm/xe: Split GuC communication initializationMichal Wajdeczko1-0/+1
Soon we will be trying to communicate with the GuC firmware very early during VF driver probe, before we finish normal init steps. Split GuC communication initialization code so the GuC MMIO based communication xe_guc_mmio_send() functions will work where needed.

2023-12-21drm/xe/guc: Promote guc_to_gt/xe helpers to .hMichal Wajdeczko1-0/+11
Duplicating these helpers in almost every .c file is a bad idea. Define them as inlines in .h file to allow proper reuse.

2023-12-21drm/xe: base definitions for the GSCCSDaniele Ceraolo Spurio1-0/+1
The first step in introducing the GSCCS is to add all the basic defs for it (name, mmio base, class/instance, lrc size etc).

2023-12-21drm/xe/pm: Init pcode and restore vram on power lostAnshuman Gupta1-0/+1
Don't init pcode and restore VRAM objects in vain. We can rely on primary GT GUC_STATUS to detect whether card has really lost power even when d3cold is allowed by xe. Adding d3cold.lost_power flag to avoid pcode init and vram restoration. Also cleaning up the TODO code comment. v2: - %s/xe_guc_has_lost_power()/xe_guc_in_reset(). - Used existing gt instead of new variable. [Rodrigo] - Added kernel-doc function comment. [Rodrigo] - xe_guc_in_reset() return true if failed to get fw.

2023-12-20drm/xe: Sort includesLucas De Marchi1-1/+1
Sort includes and split them in blocks: 1) .h corresponding to the .c. Example: xe_bb.c should have a "#include "xe_bb.h" first. 2) #include <linux/...> 3) #include <drm/...> 4) local includes 5) i915 includes This is accomplished by running `clang-format --style=file -i --sort-includes drivers/gpu/drm/xe/*.[ch]` and ignoring all the changes after the includes. There are also some manual tweaks to split the blocks. v2: Also sort includes in headers Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2023-12-12drm/xe: Introduce a new DRM driver for Intel GPUsMatthew Brost1-0/+57
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 <matthew.brost@intel.com> Co-developed-by: Matthew Auld <matthew.auld@intel.com> Co-developed-by: Matt Roper <matthew.d.roper@intel.com> Co-developed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Co-developed-by: Francois Dugast <francois.dugast@intel.com> Co-developed-by: Lucas De Marchi <lucas.demarchi@intel.com> Co-developed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Co-developed-by: Philippe Lecluse <philippe.lecluse@intel.com> Co-developed-by: Nirmoy Das <nirmoy.das@intel.com> Co-developed-by: Jani Nikula <jani.nikula@intel.com> Co-developed-by: José Roberto de Souza <jose.souza@intel.com> Co-developed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Co-developed-by: Dave Airlie <airlied@redhat.com> Co-developed-by: Faith Ekstrand <faith.ekstrand@collabora.com> Co-developed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Co-developed-by: Mauro Carvalho Chehab <mchehab@kernel.org> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com>
