drm/xe: Update wedged.mode only after successful reset policy change

2026-01-08T21:07:42Z

Previously, the driver's internal wedged.mode state was updated without verifying whether the corresponding engine reset policy update in GuC succeeded. This could leave the driver reporting a wedged.mode state that doesn't match the actual reset behavior programmed in GuC. With this change, the reset policy is updated first, and the driver's wedged.mode state is modified only if the policy update succeeds on all available GTs. This patch also introduces two functional improvements: - The policy is sent to GuC only when a change is required. An update is needed only when entering or leaving XE_WEDGED_MODE_UPON_ANY_HANG, because only in that case the reset policy changes. For example, switching between XE_WEDGED_MODE_UPON_CRITICAL_ERROR and XE_WEDGED_MODE_NEVER doesn't affect the reset policy, so there is no need to send the same value to GuC. - An inconsistent_reset flag is added to track cases where reset policy update succeeds only on a subset of GTs. If such inconsistency is detected, future wedged mode configuration will force a retry of the reset policy update to restore a consistent state across all GTs.

Allow for runtime modification to page reclamation feature through debugfs configuration. This parameter will only take effect if the platform supports the page reclamation feature by default. v2: - Minor comment tweaks. (Shuicheng) - Convert to kstrtobool_from_user. (Michal) - Only expose page reclaim file if page reclaim flag initially supported and with that, remove xe_match_desc usage.

drm/xe: Move VRAM MM debugfs creation to tile level

2025-11-27T13:43:07Z

Previously, VRAM TTM resource manager debugfs entries (vram0_mm / vram1_mm) were created globally in the XE debugfs root directory. But technically, each tile has an associated VRAM TTM manager, which it can own. Let's create VRAM memory manager debugfs entries directly under each tile's debugfs directory for better alignment with the per-tile memory layout.
