Subject: [PATCH AUTOSEL 5.14 08/21] habanalabs: fix mmu node address resolution in debugfs
Date: Thu, 16 Sep 2021 22:33:02 -0400	[thread overview]
Message-ID: <20210917023315.816225-8-sashal@kernel.org> (raw)
In-Reply-To: <20210917023315.816225-1-sashal@kernel.org>

From: Yuri Nudelman <ynudelman@habana.ai>

[ Upstream commit 09ae43043c748423a5dcdc7bb1e63e4dcabe9bd6 ]

The address resolution via debugfs was not taking into consideration the
page offset, resulting in a wrong address.
