RTOS: VSDK - Issue with playing HD (1920*1080) videos in 1920* 720 display resolution

Other Parts Discussed in Thread: DRA744

Tool/software: TI-RTOS

Hi all,

We are using DRA746-Jacinto processor and 12.3 inch display (1920 * 720).
We are using vsdk3dot1 version.
We are running below usecase in IPU1 core. With the below usecase (weston_dualcamera_dsswb),we are not able to play HD videos.
We are using ipu2  for video decoding.

UseCase: weston_dualcamera_dsswb

Capture_0 -> Display_Video0
Capture_1 -> Display_Video1
DefLink_dispDist (A15) -> Display_Gfx
DefLink_dispDist_1 (A15) -> Display_vid1
Capture_dsswb -> Alg_SwCrc


Also we tried another (weston_dualcamera_screen)usecase, in that HD (1920*1080) videos playing for few seconds & then crashes. We also observe flickers while playing HD videos.

"UseCase: weston_dualcamera_screen"

Capture_0 -> Display_Video0
Capture_1 -> Display_Video1
DefLink_dispDist (A15) -> Display_Gfx
Capture_dsswb -> Alg_SwCrc

adv_high_mediaone_logs.txt


But We also have a similar usecase as below, running in dra744 Jacinto which has 7 inch display (800 *480).We don't find issues in this case.

DRA744 Jacinto & 7 inch display

Capture_0 -> Display_Video0
DefLink_dispDist (A15) -> Display_Gfx
DefLink_dispDist_1 (A15) -> Display_vid1
Capture_dsswb -> Alg_SwCrc

Can you please support on this issue ?

Regards,
Gokul

    Hi Gokul,

    Couple of questions:

    1. Can you confirm if the Vision-SDK version used is 3.01? vDRM support is lacking on Vision-SDK 3.01.
    2. Have you modified the timing parameters on the display link for 1920x720 configuration? By default the display link is set up to 1920x1080 configuration.

    Regards

    1 .Yes Shravan. We are using vision-SDK 3 .01 version. It has weston-binary changes for M4 as display-server.
    2 It is customized board & we have updated timing parameters for our display.

    Gokul

    Hi Gokul,
    1) Is the issue seen only for 1920x1080 streams? Other smaller resolution streams work fine?
    2) What is the observation if you don't use window-resolution property of the waylandsink plugin in the pipeline?
    3) Please share dmesg logs when this issue happens.

    Thanks

    Hi Ram,

    1) Is the issue seen only for 1920x1080 streams? Other smaller resolution streams work fine?

    It is observed in other video also  (H264-MPEG4 AVC 1280*720) .

    No issue is  observed in playing (MPEG4 480*360 )

    2) What is the observation if you don't use window-resolution property of the waylandsink plugin in the pipeline?

    No change in obervation .same behaviour

    3) Please share dmesg logs when this issue happens

    Hii Gokul,
    Error omapdrm omapdrm.0: could not remap: -12 (3) means
    TILER memory of 128MB is exhauasted.

    For lower resolution streams, it is able to fit within 128MB .

    Can you share details of
    cat /sys/kernel/debug/dri/0/tiler_map
    and
    cat /sys/kernel/debug/dri/0/gem

    before starting video playback ?

    Hi Gokul,
    For the timer log , all graphics buffers are allocated in TILER region (5400K = 1920x720x4) and there will be no space left for ducati when video playback starts for Full HD video buffers.

    Please apply the patch mentioned in this link (PSDKLA-3573)
    processors.wiki.ti.com/.../Processor_SDK_Linux_Automotive_Post_Release_Fixes

    These patches are to allocate buffers in CMA region.

    Thanks

    Hi Ram,

    We tried manually updating sgx-um & libdrm libraries. Weston is not coming up.

    Is these changes applicable for VSDK 3 dot 1 version with M4 as display- server ?

    Hi Gokul,
    Please share your current bb and bbappend files for sgx-um, Libdrm, libgm, kernel and Weston.

    From the commitID you shared , this should have worked.

    Hi Gokul,
    I checked bb files of ti-sgx-um, libdrm and libgbm shared by your team.
    Current SRCREV for sgx-um is d184140aa5c17e13e1bf21151f1a7bc068bdf8bf.
    With 1145367010f416dbed87884bac329158eda26777 commit-id, there is only one line change is there in sgx-um to add a flag before creating buffers .

    Just upgrading the sgx-um to this commit-ID should have worked and weston should have come up.
    Can you please double check again?

    Thanks

    Hi Gokul,
    Switch back to commitID d184140aa5c17e13e1bf21151f1a7bc068bdf8bf and copy only libdbm.so from commit-id
    1145367010f416dbed87884bac329158eda26777 (omap5-sgx-ddk-um-linux/targetfs/jacinto6evm/lib/libdbm.so) and confirm weston is coming up.

    Only this .so has the change required to create dumb buffers in CMA region instead of TILER.

    Thanks

    Forgot to mention, please increase cma in bootargs to 128MB or more if it is 64MB.

    This could be the issue why Weston is not coming up.

    Hi Ram.

    We will add cma=128M in the kernel bootargs.
    Do we need to mention the cma region in dts ?

    Regards,
    Gokul
  • 0 in reply to Gokul Kujulva
    TI__Mastermind 30480 points

    Hi Gokul,

    cma configuration in bootArgs should be sufficient. I will check if any change required in dts file. cma configuration from 64MB to 128MB is required if there is failure during allocation but your weston doesn't show any allocation failure .

    and the modified libgbm.so just adds a flag which tells the kernel to allocate buffer in CMA region. Since you have not modified the kernel yet with the patches, this should not matter now.

    but weston should come up first.

    Thanks

    Hi Ram,

    From where, the weston graphics buffer memory will be allocated ? Is it from cma or tiler memory ? we are using vsdk3.01 version.

    I think, from vsdk3.04 version the weston graphics buffer memory will be allocated from cma .

    Can you please check with Subhajit ?

    Hi Gokul,
    PSDKLA3.02 supported allocating graphics buffers in TILER memory. After few customers reported video playback issue due to no memory left for ducati in TILER, TI added patches for PSDKLA-3753(mentioned in Post release update) to allocate graphics buffers in CMA region.

    PSDKLA3.04 + VISION-SDK3.04 combination supported CMA for weston with vDRM.

    Are you able to get weston up when you replaced libdbm.so* to rootfs?

    Hello Ram,

    Related to Weston Crash you suggested three components, please provide your feedback for below queries:
    1. Kernel Patches --> patches related to kernel are already part of our kernel tree, so need to apply.
    2. libdrm --> Is it required to add.
    3. sgx-um --> Only libdbm.so need to update?
    4. Update cma=128 boot arguments need to update .

    Hi Ikshwaku,
    Yes, you need to apply patches on kernel, libdrm and sgx-um and make changes for in bootArgs to reserve atleast 128MB in cma.

    Could you bringup weston when you just replaced libdbm.so* without kernel patches?

    ok,
    Can you do this experiment?
    Stay with current sgx-um and after boot, stop weston.
    Check how tiler_map looks like with cat /sys/kernel/debug/dri/0/tiler_map

    Run kmscube application in background and check tiler_map. This should show 3 5400KB allocation pattern (for your 1920x720 display) in tiler_map.

    Now upgrade sgx-um to the commitID to 1145367010f416dbed87884bac329158eda26777
    and run kmscube and check how tiler_map look like with cat /sys/kernel/debug/dri/0/tiler_map

    There should be no change in tiler_map before and after kmscube launch since graphics buffers will no more be allocated in TILER and will be in CMA region.

    Hi Ramprasad,

    After  adding the bootargs cma=128M@0xB0000000., Weston is running.

    But still the same issue is seen. 

    I am attaching the tiler logs and dmesg logs.

    Hi Gokul,

    After applying the sgx patch, ideally tiler_map pattern should be empty( no memory occupied) but I still see memory 5400kb pattern in tiler_map.

    Can you check

    1) After boot stop Weston and check tiler_map.

    2)Start Weston and check tiler_map

    3) Compare if these two patterns between before and after applying sgx-um patch.

    I see many other allocations in TILer, do you know what are those allocations?

    Are you still seeing omapdrm: could not remap error after starting video playback?

    Can you also share /process/meningitis details?

    Does your HMI application uses omap_bo_new() to allocate buffers?

    If yes, it needs to set no flag with OMAP_MEM_CONTIG.

    Thanks

    Hi Ramprasad,

    Please find my inline comments

    1) After boot stop Weston and check tiler_map.

    2)Start Weston and check tiler_map

    >>There is no difference in tiler map for 1 & 2 case. Same result. Attached log 

    3) Compare if these two patterns between before and after applying sgx-um patch.

    >>with sgx-um patches, nearly 10 mb( 2* 5400K )used. Without patches, more than 10 mb used (attached log)

    I see many other allocations in TILer, do you know what are those allocations? I am not sure, who is allocating.

    Are you still seeing omapdrm: could not remap error after starting video playback? No .

    But  always display goes blank. Also sometimes target get reset.

    Now we have nearly 110 MB left in tiler. But still Why we are n't able to play HD videos ?

    Hi Ram,

    After applying this patches, display goes blank & sometimes target get reset.

    Hi Gokul,
    Comparing the with and without CMA logs, now all graphics buffers are allocated in CMA and so around 110MB TILER is available for video playback usecase
    which is sufficient for single display video-playback usecase, but not still clear why 2 x 5400KB of patterns are there.

    There is no issue with "omapdrm: could not remap" error in dmesg means TILER is available for video playback and there is sufficient memmory.

    1) Do you see target getting reset with only HD videos? or any other smaller resolution videos also? Upto what resolution it works?
    2) Can you try running manual gstreamer pipeline with video-sink set to fakesink? This is just to check if video decoding + vpe is causing any issue.
    3) Please collect dmesg and userspace logs when the issue happens.

    Thanks
    Ram

    Hi Ram,

    1. It is observed in HD videos.I have already transferred the videos. (a1 .mp4 & e1.mp4 not working )
    It will play for one or two times and then display goes Blank & system gets reset sometimes.

    2 Please update the complete gstreamer command.

    3. I have already updated the logs . Do you have any macro to increase the verbosity & print the logs from all cores ?

    Have you started testing this use-case from your end ?

    Hi Gokul,
    Can you try with these gstreamer pipelines instead of starting the playback using HMI?
    gst-launch-1.0 playbin uri=file:///tmp/SDCard_Slot1-p1/a1.mp4 video-sink=waylandsink ?

    The tiler_map logs you shared seems just before starting the videoplayback. Please keep on executing
    cat /sys/kernel/debug/dri/t0/tiler_map during playback and check if the pattern show all 128MB is occupied and omapdrm: could not remap error is observed or not.

    The logs you share doesn't show any error or problem. I didn't get any clue here.

    Is it possible to do one experiment? Change your display back to 800x480 and check if the issue is observed now with these two changes you have made now. a) SGX-UM update b) CMA in bootargs update.

    Thanks

    Hi Ram,

    We tried via  gst- command. The video plays for two to three times & then display goes blank.

    Also sometimes  display goes blank & target will get reset.

     

    while true

    > do

    > gst-launch-1.0 playbin uri=file:///tmp/SDCard_Slot1-p1/vd/a1.mp4 video-sink=wa ylandsink

    > sleep 3

    > layer-add-surfaces 1000 1 &

    > done

    Ikshwaku tried your (SGX-UM update , CMA in bootargs ) patches in 7 inch. There is no issue in 7 inch display.

    Hi Gokul,


    Can you please provide the output of the below command.

    Hi Ikshwaku,
    Can you try these two experiments individually on 1920x720 display?

    while true
    > do
    > gst-launch-1.0 playbin uri=file:///tmp/SDCard_Slot1-p1/vd/a1.mp4 video-sink=fakesink
    > sleep 3
    > done

    This is to confirm if decode + vpe is causing the issue or not. This doesn't involve display. Check if loop runs more than 3 iterations, but
    you don't observe anything on display.

    If above experiment doesn't reproduce display blank issue try below GST pipeline.
    gst-launch-1.0 videotesrsrc ! 'video/x-raw, format=NV12 , width=1920, height=720' ! waylandsink use-drm=true

    This involves only display , no decoding but continuously 1920x720 NV12 buffers are submitted to display.
    If this pipeline reproduces display going blank issue, there could be issue with display settings.

    Hi Gokul,

    Just to confirm, this value ( omapconf read 0x58001018 = 0x0) is recorded when the screen is blank correct / system resets correct?

    Hi Shravan,

    We checked the value after display blank & shows 0x0.

    Hello Ram,

    I have tried this experiment:
    while true
    > do
    > gst-launch-1.0 playbin uri=file:///tmp/SDCard_Slot1-p1/vd/a1.mp4 video-sink=fakesink
    > sleep 3
    > done

    And issue is reproduced in the third iteration.

    Hi Ikshwaku,

    Could it be possible to add a heart-beat code on the IPU? I assume you're using vision-SDK. Can you add message in the IPU code which prints every second. I assume you're using IPU-1 for VSDK, so you can add a print message in the function IPU1_0_main which prints every second. The function is found in the file links_fw/src/rtos/bios_app_common/tda2xx/ipu1_0/src/main_common_ipu1_0.c in vision-SDK.
    This will help us determine, if IPU controlling display is still running.

    Regards

    Hi Shravan,

    As we discussed in the last call, I checked the /sys/kernel/debug/remoteproc/remoteproce0/status value . It shows running only.

    But sometimes we will not get control to console & system resets.

    Regards,
    Gokul

    Hi Ikshwaku,
    Can you check the behavior for these two pipelines?

    gst-launch-1.0 videotestsrc ! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080' ! waylandsink window-resolution=1920x720 use-drm=true

    gst-launch-1.0 videotestsrc ! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080' ! vpe ! waylandsink window-resolution=1920x720

    Thanks

    Hi Ikshwaku/Gokul,
    Are you seeing proper behavior with 30fps setting for the display for this issue also?

    Hii Ikshwaku,
    Please check if the issue is reproduced with the pipeline mentioned to try out.
