[IMX8MP][ISP] [DrmDisplay] drmSetMaster fail: -1 Unknown error -1

Dear All,

This is another question in my serie of questions related to the bring-up of ISP camera driver. My purpose is displaying the processed output of our custom RAW Bayer, 1-lane data Sony IMX296. Instead of using gst-launch command, I use the video_test program that is built together with ISP-IMX framework. My steps :
1. SSH console : manually running the the script that loads necessary modules and executes the isp_media_server daemon:

root@imx8mpevk:~# cd /opt/imx8-isp/bin/ && export ISP_LOG_LEVEL=8 root@imx8mpevk:/opt/imx8-isp/bin# ./run.sh -c imx296 -lm RUN_SCRIPT=/opt/imx8-isp/bin/run.sh RUN_SCRIPT_PATH=/opt/imx8-isp/bin Trying configuration "imx296"...

Starting isp_media_server with configuration file CAMERA0 INFO : [ISP_MEDIA_SERVER] ****************************************************************** INFO : [ISP_MEDIA_SERVER] VIV ISP Media Control Framework V4.2.2p11 (Aug 5 2021, 01:34:06) INFO : [ISP_MEDIA_SERVER] ******************************************************************

2. Launch the video_test in another the console :

sh-5.0# cd /opt/imx8-isp/bin/ && export ISP_LOG_LEVEL=0 sh-5.0# ./video_test -w 1440 -h 1080 -f YUYV -t drm -m0 INFO : [DrmDisplay] drm device '/dev/dri/card0' does not support dumb buffers INFO : [DrmDisplay] Open /dev/dri/card1 success ERROR : [DrmDisplay] drmSetMaster fail: -1 Unknown error -1 DEBUG : [DrmDisplay] DRM bufffer[0] addr=0x0xffff8de41000 size=3686400 w/h=(1280,720) buf_id=44 DEBUG : [DrmDisplay] DRM bufffer[1] addr=0x0xffff8dabd000 size=3686400 w/h=(1280,720) buf_id=48 INFO : [VIDEOTEST] Open Device: /dev/video0 (fd=6) INFO : [VIDEOTEST] Driver: viv_v4l2_device INFO : [VIDEOTEST] found viv video dev /dev/video0 INFO : [VIDEOTEST] openDevice Control User Controls INFO : [VIDEOTEST] openDevice Control viv_ext_ctrl INFO : [VIDEOTEST] openDevice, find viv ctrl id 0x98f901 INFO : [VIDEOTEST] open camdev ret : 6 INFO : [VIDEOTEST] Open Device: /dev/video0 (fd=6) INFO : [VIDEOTEST] Driver: viv_v4l2_device INFO : [VIDEOTEST] Card: VIV INFO : [VIDEOTEST] Version: 5.4.70 INFO : [VIDEOTEST] All Caps: 84200001 INFO : [VIDEOTEST] Dev Caps: 04200001 Video Test:caps supports:{ count = 1 { index = 0 width = 1440 height = 1080 fps = 60 hdr_mode = 0 } } INFO : [VIDEOTEST] Video Test: Set mode[0] INFO : [VIDEOTEST] 0: YUYV 4:2:2 0x56595559 0x0 INFO : [VIDEOTEST] 1: Y/CbCr 4:2:0 0x3231564E 0x0 INFO : [VIDEOTEST] 2: Y/CbCr 4:2:2 0x3631564E 0x0 INFO : [VIDEOTEST] 3: 10-bit Bayer BGBG/GRGR 0x30314742 0x0 DEBUG : [VIDEOTEST] V4L2 ext ctrl id: 0x98f901 DEBUG : [VIDEOTEST] V4L2 ext ctrl name: viv_ext_ctrl DEBUG : [VIDEOTEST] V4L2 ext ctrl elem size: 65536 DEBUG : [VIDEOTEST] V4L2 ext ctrl id: 0x98f903 DEBUG : [VIDEOTEST] V4L2 ext ctrl name: sensor.resw DEBUG : [VIDEOTEST] V4L2 ext ctrl elem size: 4 DEBUG : [VIDEOTEST] V4L2 ext ctrl id: 0x98f904 DEBUG : [VIDEOTEST] V4L2 ext ctrl name: sensor.resh DEBUG : [VIDEOTEST] V4L2 ext ctrl elem size: 4 DEBUG : [VIDEOTEST] VIDIOC_QUERY_EXT_CTRL: Invalid argument DEBUG : [VIDEOTEST] Sensor's caps (JSON format string):{ "caps" : [ { "bayer_pattern" : 3, "bit_width" : 10, "fps" : 60, "hdr_mode" : 0, "height" : 1080, "index" : 0, "stitching_mode" : 0, "width" : 1440 } ], "current" : 0, "default" : 0 } INFO : [VIDEOTEST] Buffer description: INFO : [VIDEOTEST] offset: 0 INFO : [VIDEOTEST] length: 3110400 INFO : [VIDEOTEST] map buffer 0xffff8d7c5000 INFO : [VIDEOTEST] Buffer description: INFO : [VIDEOTEST] offset: 3112960 INFO : [VIDEOTEST] length: 3110400 INFO : [VIDEOTEST] map buffer 0xffff8d4cd000 INFO : [VIDEOTEST] Buffer description: INFO : [VIDEOTEST] offset: 6225920 INFO : [VIDEOTEST] length: 3110400 INFO : [VIDEOTEST] map buffer 0xffff8d1d5000 INFO : [VIDEOTEST] Buffer description: INFO : [VIDEOTEST] offset: 9338880 INFO : [VIDEOTEST] length: 3110400 INFO : [VIDEOTEST] map buffer 0xffff8cedd000

And UART console shows :

[ 3030.800237] enter isp_mi_stop [ 3123.236602] enter isp_mi_stop [ 3123.349320] enter isp_s_comp [ 3123.352246] enter isp_s_comp [ 3123.355157] enter isp_s_comp [ 3123.371076] enter wdr3_hw_init [ 3123.374135] wdr3 res: 1440 1080 [ 3123.378036] enter isp_mi_start

Could someone help to clarify the error [DrmDisplay] drmSetMaster fail: -1 Unknown error -1, please ? I'm really stuck of knowing how to display correctly the output behind the ISP block.

Thanks in advance,

Khang

Hi @khang_letruong

Can you attach full kernel log after enabling drm.debug?

this gpu card0 can't create buffer, you can try to use another gpu card, maybe card1

[DrmDisplay] drm device '/dev/dri/card0' does not support dumb buffers
INFO   : [DrmDisplay] Open /dev/dri/card1 success
ERROR  : [DrmDisplay] drmSetMaster fail: -1 Unknown error -1

Hi @Zhiming_Liu ,

Thanks for you replies. Could you advice how to enable drm.debug as well as how to switch to another gpu card, please ?

Thanks very much in advance.
