Subject: [PATCH 22/23] drm/xe/svm: Add DRM_XE_SVM kernel config entry
Date: Wed, 17 Jan 2024 17:12:22 -0500 [thread overview]
Message-ID: <20240117221223.18540-23-oak.zeng@intel.com> (raw)
In-Reply-To: <20240117221223.18540-1-oak.zeng@intel.com>
DRM_XE_SVM kernel config entry is added so
xe svm feature can be configured before kernel
compilation.
