The Xe_HP architecture introduces compute engines as a new engine class.
These compute command streamers (CCS) are similar to the render engine,
except that they're intended for GPGPU usage and lack support for the 3D
pipeline.
For now we're just sending some initial "under the hood" preparation for
CCS engines without actually exposing them to userspace or adding them
to any platform's engine list yet. There may be a bit more GuC-related
updates necessary before it's safe to expose them, so the actual uabi
bits will come later once that's all worked out.
Daniele Ceraolo Spurio (3):
drm/i915/xehp: compute engine pipe_control
drm/i915/xehp/guc: enable compute engine inside GuC
drm/i915/xehp: handle fused off CCS engines
Matt Roper (8):
drm/i915/xehp: Define compute class and engine
drm/i915/xehp: CCS shares the render reset domain
drm/i915/xehp: Add Compute CS IRQ handlers
drm/i915/xehp: CCS should use RCS setup functions
drm/i915: Move context descriptor fields to intel_lrc.h
drm/i915/xehp: Define context scheduling attributes in lrc descriptor
drm/i915/xehp: Enable ccs/dual-ctx in RCU_MODE
drm/i915/xehp: Add compute workarounds
Matthew Brost (1):
drm/i915/xehp: Don't support parallel submission on compute / render
Srinivasan Shanmugam (1):
drm/i915/xehpsdv: Move render/compute engine reset domains related
workarounds
