drm/xe/compat: reduce i915_utils.[ch]

2025-10-31T11:24:28+00:00

Reduce the compat i915_utils.h to only cover the requirements of MISSING_CASE() in soc/ and the few i915_inject_probe_failure() instances, instead of including the entire i915_utils.h from i915. This prevents new users for the utilities from cropping up. With this, we can remove the xe/display/ext/i915_utils.c altogether.

drm/i915/display: add intel_display_vtd_active()

2025-10-31T11:09:22+00:00

Add intel_display_vtd_active() to utils. It's intentional duplication with i915_utils.h i915_vtd_active(), but reduces duplication with xe. Win some, lose some.

drm/i915: Introduce i915_error_regs

drm/xe: Make irq enabled flag atomic

2024-12-11T18:20:53+00:00

The irq.enabled flag was protected by a spin lock (irq.lock). By making it atomic we no longer need to wait for the spin lock in irq handlers. This will become especially useful for MSI-X irq handlers to prevent lock contention between different interrupts.

drm/i915/irq: add struct i915_irq_regs triplet

2024-10-03T12:42:41+00:00

Add struct i915_irq_regs to hold IMR/IER/IIR register offsets to pass to gen3_irq_reset() and gen3_irq_init(). This helps in grouping the registers and further cleanup. Note: gen3_irq_reset() and gen3_irq_init() really did have the IMR/IER/IIR parameters in different order.

drm/xe/display: Fix dummy __i915_inject_probe_error()

2023-12-21T16:46:17+00:00

When CONFIG_DRM_I915_DEBUG is not set, a dummy __i915_inject_probe_error() is provided on the xe side. Use the same logic as in drivers/gpu/drm/i915/i915_utils.c to ifdef it out. This fixes the build with W=1 and without that config: CC [M] drivers/gpu/drm/xe/display/ext/i915_utils.o ../drivers/gpu/drm/xe/display/ext/i915_utils.c:19:5: error: no previous prototype for ‘__i915_inject_probe_error’ [-Werror=missing-prototypes] 19 | int __i915_inject_probe_error(struct drm_i915_private *i915, int err, | ^~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Lucas De Marchi Reviewed-by: Rodrigo Vivi Signed-off-by: Rodrigo Vivi

drm/xe/display: Implement display support

2023-12-21T16:43:39+00:00

As for display, the intent is to share the display code with the i915 driver so that there is maximum reuse there. We do this by recompiling i915/display code twice. Now that i915 has been adapted to support the Xe build, we can add the xe/display support. This initial work is a collaboration of many people and unfortunately this squashed patch won't fully honor the proper credits.
