eb9702ad - drm/xe: Allow num_batch_buffer / num_binds == 0 in IOCTLs

Tue, 05 Dec 2023 18:39:54 +0000

drm/xe: Allow num_batch_buffer / num_binds == 0 in IOCTLsThe idea being out-syncs can signal indicating all previous operationson the bind queue are complete. An example use case of this would besupport for implementing vkQueueWaitIdle easily.All in-syncs are waited on before signaling out-syncs. This isimplemented by forming a composite software fence of in-syncs andinstalling this fence in the out-syncs and exec queue last fence slot.The last fence must be added as a dependency for jobs on user execqueues as it is possible for the last fence to be a composite softwarefence (unordered, ioctl with zero bb or binds) rather than hardwarefence (ordered, previous job on queue).Cc: Thomas Hellström Signed-off-by: Matthew Brost Reviewed-by: Thomas Hellström Signed-off-by: Rodrigo Vivi List of files: /linux-6.15/drivers/gpu/drm/xe/xe_sync.h

f3e9b1f4 - drm/xe: Remove async worker and rework sync binds

Thu, 14 Sep 2023 20:40:50 +0000

drm/xe: Remove async worker and rework sync bindsAsync worker is gone. All jobs and memory allocations done in IOCTL toalign with dma fencing rules.Async vs. sync now means when do bind operations complete relative tothe IOCTL. Async completes when out-syncs signal while sync completeswhen the IOCTL returns. In-syncs and out-syncs are only allowed in asyncmode.If memory allocations fail in the job creation step the VM is killed.This is temporary, eventually a proper unwind will be done and VM willbe usable.Signed-off-by: Matthew Brost Reviewed-by: Thomas Hellström Signed-off-by: Rodrigo Vivi List of files: /linux-6.15/drivers/gpu/drm/xe/xe_sync.h

dd08ebf6 - drm/xe: Introduce a new DRM driver for Intel GPUs

Thu, 30 Mar 2023 21:31:57 +0000

drm/xe: Introduce a new DRM driver for Intel GPUsXe, is a new driver for Intel GPUs that supports both integrated anddiscrete platforms starting with Tiger Lake (first Intel Xe Architecture).The code is at a stage where it is already functional and has experimentalsupport for multiple platforms starting from Tiger Lake, with initialsupport implemented in Mesa (for Iris and Anv, our OpenGL and Vulkandrivers), 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 i915driver so that there is maximum reuse there. But it is not addedin this patch.This initial work is a collaboration of many people and unfortunatelythe big squashed patch won't fully honor the proper credits. But let'sget some git quick stats so we can at least try to preserve some of thecredits: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 List of files: /linux-6.15/drivers/gpu/drm/xe/xe_sync.h
