Subject: [PATCH AUTOSEL 5.19 13/22] ALSA: hda/tegra: Align BDL entry to 4KB boundary
Date: Wed, 14 Sep 2022 05:00:54 -0400 [thread overview]
Message-ID: <20220914090103.470630-13-sashal@kernel.org> (raw)
In-Reply-To: <20220914090103.470630-1-sashal@kernel.org>
From: Mohan Kumar <mkumard@nvidia.com>
[ Upstream commit 8d44e6044a0e885acdd01813768a0b27906d64fd ]
AZA HW may send a burst read/write request crossing 4K memory boundary.
The 4KB boundary is not guaranteed by Tegra HDA HW. Make SW change to
include the flag AZX_DCAPS_4K_BDLE_BOUNDARY to align BDLE to 4K
boundary.
