Subject: [PATCH AUTOSEL 5.2 018/171] drm/amd/display: Fill prescale_params->scale for RGB565
Date: Thu, 18 Jul 2019 23:54:09 -0400	[thread overview]
Message-ID: <20190719035643.14300-18-sashal@kernel.org> (raw)
In-Reply-To: <20190719035643.14300-1-sashal@kernel.org>

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

[ Upstream commit 1352c779cb74d427f4150cbe779a2f7886f70cae ]

[Why]
An assertion is thrown when using SURFACE_PIXEL_FORMAT_GRPH_RGB565
formats on DCE since the prescale_params->scale wasn't being filled.

Found by a dmesg-fail when running the
igt@kms_plane@pixel-format-pipe-a-planes test on Baffin.

[How]
Fill in the scale parameter.
