2023-10-02drm/i915: Add missing GSCCS documentationRodrigo Vivi
Introduce the basic documentation about GSC CS. This "GPU Basics" section is focused on explaining the hardware rather than the driver/uapi, so let's make sure GSC is also properly documented here. v2: Fixes from Matt: typos and acronym.

2023-10-02drm/i915: Add missing CCS documentationRodrigo Vivi
Let's introduce the basic documentation about CCS. While doing that, also removed the legacy execution flag name. That flag simply doesn't exist for CCS and it is not needed on current context submission. Those flag names are only needed on legacy context, while on new ones we only need to pass the engine ID. It is worth mention that this documentation should probably live with the engine definitions rather than in the i915.rst file directly and that more updates are likely need in this section. But this should come later. v2: Overall improvements from Matt and Tvrtko.

2023-09-30drm/i915: Toggle binder context ready statusNirmoy Das
Toggle binder context ready status when needed. To issue gpu commands, the driver must be primed to receive requests. Maintain binder-based GGTT update disablement until driver probing completes. Moreover, implement a temporary disablement of blitter prior to entering suspend, followed by re-enablement post-resume. This is acceptable as those transition periods are mostly single threaded. v2: move changes to lower levels from i915_driver.c(Jani). use new function for setting context ready status.

2023-09-30drm/i915: Implement GGTT update method with MI_UPDATE_GTTNirmoy Das
Implement GGTT update method with blitter command, MI_UPDATE_GTT and install those handlers if a platform requires that. v2: Make sure we hold the GT wakeref and Blitter engine wakeref before we call mutex_lock/intel_context_enter below. When GT/engine are not awake, the intel_context_enter calls into some runtime pm function which can end up with kmalloc/fs_reclaim. But trigger fs_reclaim holding a mutex lock is not allowed because shrinker can also try to hold the same mutex lock. It is a circular lock. So hold the GT/blitter engine wakeref before calling mutex_lock, to fix the circular lock.

These callbacks may pull in their own forest of locks, which we do not want to conflate with the intel_wakeref.mutex.

2023-09-29drm/i915: define I915 during i915 driver buildJani Nikula
The xe driver will reuse i915 display code by compiling it separately as part of xe. We'll want to be able to distinguish between building the i915 display code for i915 and xe. Define I915 when building i915.
