Subject: [PATCH v2] media: Hantro: Correct G2 init qp field
Date: Tue, 24 May 2022 13:59:45 +0200	[thread overview]
Message-ID: <20220524115945.2294015-1-benjamin.gaignard@collabora.com> (raw)

Documentation said that g2 init_qp field use bits 24 to 30 of
the 8th register.
Change the field mask to be able to set 7 bits and not only 6 of them.

Conformance test INITQP_B_Main10_Sony_1 decoding is OK with this
patch.

Fixes: cb5dd5a0fa518 ("media: hantro: Introduce G2/HEVC decoder")
Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com>

With this patch and the patches needed for 10-bit support
Fluster HEVC score is 137/147
