Subject: [Intel-gfx] [PATCH 3/3] drm/i915/error: Fix object page offset within a region
Date: Mon, 18 Jan 2021 14:17:32 +0000 [thread overview]
Message-ID: <20210118141732.90173-3-matthew.auld@intel.com> (raw)
In-Reply-To: <20210118141732.90173-1-matthew.auld@intel.com>
From: CQ Tang <cq.tang@intel.com>
io_mapping_map_wc() expects the offset to be relative to the iomapping
base address. Currently we just pass in the physical address for the
page which only works if the region.start starts at zero.
