Subject: [PATCH 04/11] drm/xe: Add page reclamation info to device info
Date: Tue, 18 Nov 2025 17:05:45 +0800	[thread overview]
Message-ID: <20251118090552.246243-5-brian3.nguyen@intel.com> (raw)
In-Reply-To: <20251118090552.246243-1-brian3.nguyen@intel.com>

From: Oak Zeng <oak.zeng@intel.com>

Starting from Xe3p, HW adds a feature assisting range based page
reclamation. Introduce a bit in device info to indicate whether
device has such capability.
