Subject: [PATCH v3 14/24] media: rkvdec: h264: Fix bit depth wrap in pps packet
Date: Tue, 5 Apr 2022 16:44:15 -0400 [thread overview]
Message-ID: <20220405204426.259074-15-nicolas.dufresne@collabora.com> (raw)
In-Reply-To: <20220405204426.259074-1-nicolas.dufresne@collabora.com>
From: Jonas Karlman <jonas@kwiboo.se>
The luma and chroma bit depth fields in the pps packet are 3 bits wide.
8 is wrongly added to the bit depth values written to these 3 bit fields.
Because only the 3 LSB are written, the hardware was configured
correctly.
Correct this by not adding 8 to the luma and chroma bit depth value.
Fixes: cd33c830448ba ("media: rkvdec: Add the rkvdec driver")
