Subject: [PATCH RFC 02/12] media: rockchip: Add a VEPU580 stateless video encoder driver
Date: Tue, 10 Nov 2026 10:08:04 +0000 [thread overview]
Message-ID: <20261110-rkvenc-v1-2-ea8b47122d8c@gmail.com> (raw)
In-Reply-To: <20261110-rkvenc-v1-0-ea8b47122d8c@gmail.com>
From: Arun Iyengar <aiyengar1990@gmail.com>
Add a V4L2 m2m driver for the VEPU580 (RKVENC) encoder of the RK3588,
using the H.264 stateless encode uAPI and helpers (v4l2-h264-enc) proposed
by Paul Kocialkowski. H.264 is supported:
- Baseline, Main and High profile, CAVLC and CABAC, 8x8 transform, a
single slice per picture, I and P pictures with one reference picture
(the hardware has a single reference read port);
- input in NV12, NV12M, NV21, YUV420, YUV420M, YUYV or UYVY, up to
4096x4096 (wider pictures need the external line buffer, not handled);
- the parameter sets come from the v4l2-h264-enc RBSP writer and are put
at the start of the CAPTURE buffer; the hardware then writes the start
code, NAL header and slice header from its syntax registers, followed by
the slice data;
- reconstructed and reference pictures are driver-internal FBC buffers
with their quarter-resolution thumbnails, managed by the v4l2-h264-enc
reference code;
- direct QP and constant quality use a fixed frame QP. In CBR mode the
frame size target of the common rate control is also given to the
hardware macroblock row rate control with adaptive quantisation, which
may move the QP of each row by up to row_rc_qp_range (module
parameter, default 2, 0 for frame-level rate control only). The average
QP measured by the hardware is exposed through
V4L2_CID_MPEG_VIDEO_AVERAGE_QP. It is not fed back into the frame-level
statistics: with adaptive quantisation it sits below the frame QP and
the estimate would spiral down.
Each of the two cores is a component of a virtual master device that owns
the video device. The cores share the first core's IOMMU domain, and
v4l2_m2m_set_max_parallel_jobs() lets jobs of different contexts run on
both cores at the same time. The dual-core handshake (one stream on two
cores) is not used.
The codec specific part sits behind a small ops structure so that HEVC can
be added once a stateless HEVC encode uAPI exists.
Provenance: there is no public documentation of this block. The register
layout and meanings, and the default tuning values (RDO lambda and weight
tables, intra/ATR thresholds, motion search parameters, flat quantisation
tables, row rate control thresholds) were derived from the Rockchip MPP
user space library (Apache-2.0: vepu580_common.h, hal_h264e_vepu580.c,
hal_h264e_vepu580_reg.h, hal_h264e_vepu580_tune.c, vepu5xx_common.c).
They are written as named fields and formulas, not register dumps. The
power, watchdog, per-frame force clear and reset/IOMMU recovery sequences
follow the Rockchip BSP mpp_rkvenc2 driver (GPL-2.0) as found in an
out-of-tree port, with the interrupt status bits corrected to the layout
used by MPP (safe clear done is bit 2, watchdog bit 8).
