2024-08-22drm/xe: Remove unnecessary drm_mm.h includesRodrigo Vivi
These includes are no longer necessary, and where appropriate are replaced by the linux/types.h one.

2024-05-28drm/xe: allow unaligned start and size xe_res_cursor parametersAndrzej Hajda
xe_res_cursor code does not depend on the alignment. On the other side unaligned accesses are useful from pread/pwrite point of view.

2023-12-21drm/xe: Update SPDX deprecated license identifierThomas Hellström
The "GPL-2.0" SPDX license identifier is deprecated. Update the code to use "GPL-2.0-only" instead. Choose this identifier over "GPL-2.0-or-later" since it's the most restrictive of the two and it's not fully clear that "GPL-2.0" also allows "GPL-2.0-or-later".

2023-12-21drm/xe: Simplify xe_res_get_buddy()Brian Welty
We can remove the unnecessary indirection thru xe->tiles[] to get the TTM VRAM manager. This code can be common for VRAM and STOLEN. Signed-off-by: Brian Welty <brian.welty@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2023-12-21drm/xe: Prefer WARN() over BUG() to avoid crashing the kernelFrancois Dugast
Replace calls to XE_BUG_ON() with calls XE_WARN_ON() which in turn calls WARN() instead of BUG(). BUG() crashes the kernel and should only be used when it is absolutely unavoidable in case of catastrophic and unrecoverable failures, which is not the case here.

2023-12-19drm/xe: Move VRAM from GT to tileMatt Roper
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.

2023-12-12drm/xe: Implement stolen memory.Maarten Lankhorst
This adds support for stolen memory, with the same allocator as vram_mgr. This allows us to skip a whole lot of copy-paste, by re-using parts of xe_ttm_vram_mgr. The stolen memory may be bound using VM_BIND, so it performs like any other memory region. We should be able to map a stolen BO directly using the physical memory location instead of through GGTT even on old platforms, but I don't know what the effects are on coherency.

2023-12-12drm/xe: Introduce a new DRM driver for Intel GPUsMatthew Brost
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>
