Subject: [PATCH v2 00/11] Rockchip ISP1 Driver
This patch series add a ISP(Camera) v4l2 driver for rockchip rk3288/rk3399 SoC.
Kernel Branch:
https://github.com/wzyy2/linux/tree/rkisp1/drivers/media/platform/rockchip/isp1
Below are some infomations about driver/hardware:
Rockchip ISP1 have many Hardware Blocks(simplied):
MIPI --> ISP --> DCrop(Mainpath) --> RSZ(Mainpath) --> DMA(Mainpath)
DMA-Input --> --> DCrop(Selfpath) --> RSZ(Selfpath) --> DMA(Selfpath);)
(Acutally the TRM(rk3288, isp) could be found online...... which contains a more detailed block diagrams ;-P)
The funcitons of each hardware block:
Mainpath : up to 4k resolution, support raw/yuv format
Selfpath : up tp 1080p, support rotate, support rgb/yuv format
RSZ: scaling
DCrop: crop
ISP: 3A, Color processing, Crop
MIPI: MIPI Camera interface
Media pipelines:
Mainpath, Selfpath <-- ISP subdev <-- MIPI <-- Sensor
3A stats <-- <-- 3A parms
Code struct:
capture.c : Mainpath, Selfpath, RSZ, DCROP : capture device.
rkisp1.c : ISP : v4l2 sub-device.
isp_params.c : 3A parms : output device.
isp_stats.c : 3A stats : capture device.
mipi_dphy_sy.c : MIPI : sperated v4l2 sub-device.
Usage:
ChromiumOS:
use below v4l2-ctl command to capture frames.
v4l2-ctl --verbose -d /dev/video4 --stream-mmap=2
--stream-to=/tmp/stream.out --stream-count=60 --stream-poll
use below command to playback the video on your PC.
mplayer /tmp/stream.out -loop 0 --demuxer=rawvideo
--rawvideo=w=800:h=600:size=$((800*600*2)):format=yuy2
or
mplayer ./stream.out -loop 0 -demuxer rawvideo -rawvideo
w=800:h=600:size=$((800*600*2)):format=yuy2
Linux:
use rkcamsrc gstreamer plugin(just a modified v4l2src) to preview.
gst-launch-1.0 rkcamsrc device=/dev/video0 io-mode=4 disable-3A=true
videoconvert ! video/x-raw,format=NV12,width=640,height=480 ! kmssink
