2023-12-19drm/xe: Allocate GT dynamicallyMatt Roper1-1/+1
In preparation for re-adding media GT support, switch the primary GT within the tile to a dynamic allocation.

2023-12-19drm/xe: Move migration from GT to tileMatt Roper1-3/+0
Migration primarily focuses on the memory associated with a tile, so it makes more sense to track this at the tile level (especially since the driver was already skipping migration operations on media GTs). Note that the blitter engine used to perform the migration always lives in the tile's primary GT today. In theory that could change if media GTs ever start including blitter engines in the future, but we can extend the design if/when that happens in the future. v2: - Fix kunit test build - Kerneldoc parameter name update v3: - Removed leftover prototype for removed function. (Gustavo) - Remove unrelated / unwanted error handling change.

2023-12-19drm/xe: Move VRAM from GT to tileMatt Roper1-1/+0
On platforms with VRAM, the VRAM is associated with the tile, not the GT. v2: - Unsquash the GGTT handling back into its own patch. - Fix kunit test build v3: - Tweak the "FIXME" comment to clarify that this function will be completely gone by the end of the series. (Lucas) v4: - Move a few changes that were supposed to be part of the GGTT patch back to that commit. (Gustavo) v5: - Kerneldoc parameter name fix.

2023-12-19drm/xe: Add backpointer from gt to tileMatt Roper1-5/+0
Rather than a backpointer to the xe_device, a GT should have a backpointer to its tile (which can then be used to lookup the device if necessary). The gt_to_xe() helper macro (which moves from xe_gt.h to xe_gt_types.h) can and should still be used to jump directly from an xe_gt to xe_device. v2: - Fix kunit test build - Move a couple changes to the previous patch.

2023-12-19drm/xe: Allow const propagation in gt_to_xe()Lucas De Marchi1-4/+4
Replace the inline function with a _Generic() so gt_to_xe() can work with a const struct xe_gt*, which leads to a const struct xe *. This allows a const gt being passed around and when the xe device is needed, compiler won't issue a warning that calling gt_to_xe() would discard the const. Rather, just propagate the const to the xe pointer being returned.

2023-12-19drm/xe: Use GuC to do GGTT invalidations for the GuC firmwareMatthew Brost1-0/+1
Only the GuC should be issuing TLB invalidations if it is enabled. Part of this patch is sanitize the device on driver unload to ensure we do not send GuC based TLB invalidations during driver unload.

2023-12-12drm/xe: Introduce a new DRM driver for Intel GPUsMatthew Brost1-0/+64
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>
