Subject: [PATCH 2/3] drm/xe: Refactor emit_clear_link_copy
Date: Thu, 7 May 2026 12:12:32 +0530 [thread overview]
Message-ID: <20260507064229.397673-7-balasubramani.vivekanandan@intel.com> (raw)
In-Reply-To: <20260507064229.397673-5-balasubramani.vivekanandan@intel.com>
Implement a function to return the length of the MEM_SET instruction.
This is to prepare for future platforms where the length of MEM_SET
instruction is expected to change.
