Subject: [PATCH AUTOSEL 6.14 27/30] drm/amdgpu: Use the right function for hdp flush
Date: Mon, 21 Apr 2025 22:15:47 -0400	[thread overview]
Message-ID: <20250422021550.1940809-27-sashal@kernel.org> (raw)
In-Reply-To: <20250422021550.1940809-1-sashal@kernel.org>

From: Lijo Lazar <lijo.lazar@amd.com>

[ Upstream commit c235a7132258ac30bd43d228222986022d21f5de ]

There are a few prechecks made before HDP flush like a flush is not
required on APU bare metal. Using hdp callback directly bypasses those
checks. Use amdgpu_device_flush_hdp which takes care of prechecks.
