DM8168 - M3-ISS assertion when Tiler enabled

Nitesh,

what i understood from your logs is you want the VFPC DEI Dual Out working in Tiled mode, right?  But output buffers are getting allocated from the non-tiled pool rather than the tiled area.  can you please check what is the value set for the port paramter  "eBufMemoryType" from app, for tiled case tjhis should be set to "OMX_BUFFER_MEMORY_TILED_8BIT"

regards

shiju

Hi Shiju,

 eBufMemoryType was set to DEFAULT and that was the reason for this issue. Thanks for the hint. To make it OMX_BUFFER_MEMORY_TILED_8BIT had to add this code,

File: omx_il_client_utl.h
Function: omx_ilclient_utl_connect_components

    if (pEdgeInfo->bForceDisableTiler) {
      OMX_TEST_INIT_STRUCT(sMemTypeCfg);
      /* If using as bitstream sink dont use tiled memory */
      sMemTypeCfg.nPortIndex = nPortIndex1;
      sMemTypeCfg.eBufMemoryType = OMX_BUFFER_MEMORY_DEFAULT;
      eError = OMX_SetParameter (hComp1,
                 (OMX_INDEXTYPE)OMX_TI_IndexParamBuffMemType,
                 &sMemTypeCfg);
      OMX_TEST_BAIL_IF_ERROR ( eError );
  
      OMX_TEST_INIT_STRUCT(sMemTypeCfg);
      /* If using as bitstream sink dont use tiled memory */
      sMemTypeCfg.nPortIndex = nPortIndex2;
      sMemTypeCfg.eBufMemoryType = OMX_BUFFER_MEMORY_DEFAULT;
      eError = OMX_SetParameter (hComp2,
                (OMX_INDEXTYPE)OMX_TI_IndexParamBuffMemType,
                &sMemTypeCfg);
      OMX_TEST_BAIL_IF_ERROR ( eError );
    }
#if 1 // THIS IS ADDED
    else
    {   
      OMX_TEST_INIT_STRUCT(sMemTypeCfg);
      sMemTypeCfg.nPortIndex = nPortIndex1;
      sMemTypeCfg.eBufMemoryType = OMX_BUFFER_MEMORY_TILED_8BIT; 

      eError = OMX_SetParameter (hComp1,
                 (OMX_INDEXTYPE)OMX_TI_IndexParamBuffMemType,
                 &sMemTypeCfg);
      OMX_TEST_BAIL_IF_ERROR ( eError );
  
      OMX_TEST_INIT_STRUCT(sMemTypeCfg);
      sMemTypeCfg.nPortIndex = nPortIndex2;
      sMemTypeCfg.eBufMemoryType = OMX_BUFFER_MEMORY_TILED_8BIT;
      eError = OMX_SetParameter (hComp2,
                (OMX_INDEXTYPE)OMX_TI_IndexParamBuffMemType,
                &sMemTypeCfg);
      OMX_TEST_BAIL_IF_ERROR ( eError );

    }   
#endif

With this change assertion is gone, but we are seeing few fields partially corrupted from VFCC. I am attaching here Luma alone (1920x540) of first 12 fields of the video as got at the output of VFCC. The same behaviour is repeatable (corruption happening at the same field and same dimension) across multiple runs.

Please help in resolving this issue.

you can't configure both of the DEI outputs as tiled mode.  The VIP SC path out can be configured as either tiled or non-tiled. but the DEI SC path output is always non tiled.  so please configure your DEI outputs accordingly

Shiju,

 Setting DEI SC path to non-tiled is automatically taken care by lower layer code.

The issue that I reported was seen at the output of VFCC. Interestingly, there are few frames that are not corrupted,  on few frames few row stripes are seen and few frames are completely corrupted, as you can see in the previously attached zip file. Also this sequence seems to repeat itself. Any hint to further debug this will help.

Nitish,

are you enabling tiler in VFCC output side?  what is the data format set for VFCC output YUV 420 or YUV 422?
