Subject: [PATCH 05/23] drm/xe/svm: add helper to retrieve svm range from address
Date: Wed, 17 Jan 2024 17:12:05 -0500 [thread overview]
Message-ID: <20240117221223.18540-6-oak.zeng@intel.com> (raw)
In-Reply-To: <20240117221223.18540-1-oak.zeng@intel.com>
All valid virtual address range are maintained in svm's
range_tree. This functions iterate svm's range tree and
return the svm range that contains specific address.
