Subject: [PATCH v4 4/5] media: qcom: iris: increase H265D_MAX_SLICE to fix H.265 decoding on SC7280
Date: Sat, 31 Jan 2026 15:58:53 +0200 [thread overview]
Message-ID: <20260131-venus-iris-flip-switch-v4-4-e10b886771e1@oss.qualcomm.com> (raw)
In-Reply-To: <20260131-venus-iris-flip-switch-v4-0-e10b886771e1@oss.qualcomm.com>
Follow the commit bfe1326573ff ("venus: Fix for H265 decoding failure.")
and increase H265D_MAX_SLICE following firmware requirements on that
platform. Otherwise decoding of the H.265 streams fails withthe
"insufficient scratch_1 buffer size" from the firmware.
