Subject: [PATCH 0/1] drm/xe: TileAddrRange registers are being deprecated.
Date: Tue, 30 Sep 2025 16:26:44 -0700	[thread overview]
Message-ID: <20250930232645.600251-1-fei.yang@intel.com> (raw)

From: Fei Yang <fei.yang@intel.com>

Quoting BSpec: 59353, "The TILEx_ADDR_RANGE registers no longer have any
impact on HW behavior. They now function only as scratch registers for
communication between SoC FW and the GPU driver, and will eventually be
replaced by equivalent registers within SoC MMIO space. At that point,
these registers can be deprecated from XeTLB.".
While the transition is ongoing, the SGAddrRangeforTile continues to be
valid and works on all platforms supported by xe, reading that instead
to avoid potential breakage.
