Memory consumption calculation for a link-chain

srimugunthan dhandapani

Hi all,

I am using DVR-RDK 3.5 on DM8168 platform.

For a transcoder usecase, i have setup the following syslink chain. I have programmatically set the buf_per_ch for some links. For the rest , it takes the default .

SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0 (buf_per_ch = 6)
                |
SYSTEM_VIDEO_LINK_ID_IPC_BITS_IN_0
               |
SYSTEM_LINK_ID_VDEC_0;  (buf_per_ch = 6)
               |
SYSTEM_VIDEO_LINK_ID_IPC_OUT_M3_0
               |
SYSTEM_VPSS_LINK_ID_IPC_IN_M3_0 
               |
SYSTEM_LINK_ID_SCLR_INST_0  (buf_per_ch = 3)
               |
SYSTEM_LINK_ID_NSF_0  (buf_per_ch = 4)
               |
SYSTEM_VPSS_LINK_ID_IPC_OUT_M3_0
               |
SYSTEM_VIDEO_LINK_ID_IPC_IN_M3_0
               |
SYSTEM_LINK_ID_VENC_0 (buf_per_ch = 4)
               |
SYSTEM_VIDEO_LINK_ID_IPC_BITS_OUT_0
               |
SYSTEM_HOST_LINK_ID_IPC_BITS_IN_0


1) For an input video of width(iw) and height(ih)  and output video (ow) and height (oh) How do i calculate the total (or maximum) memory consumption after setting up this usecase.

2) When are the buffers allocated (after the links are started?, created?) and when deallocated?

3) If I have programmed the IVA map table to 16 channels(Enc-dec), is the memory consumption 16 times more?


thanks,

mugunthan

    Invoking Vsys_printDetailedStatistics will print the memory consumed in each SharedRegion .You should invoke this api after creating all the links

    Buffers are allocated at link create time

    No iva mapping only mentions which encoder decoder channels maps to which HDVICP id.It doesn't consume any memory.

    Thanks for replying. I was hoping that For this link chain i can have some rough estimates for memory consumption  given the number of channels , input resolution and output resolution.

    I think accurate memory consumption of the link-chain cannot be obtained using the linux "free" command.  Are there anyother command line tools?

    Anyways, after the links are started, printing the buffer statistics and detailed statistics gives me the following output. how do i know the current memory consumption?

    BUFFER STATS:

    IPCBITSOUTLINK:Buffer Statistics
    Num Alloc Pools:1
    PoolId | TotalBufCnt | FreeBufCnt | BufSize | AppAllocCount
    0| 6| 3| 25344| 0

    VDEC:Buffer Statistics
    ChId | InBufCnt | OutBufCnt
    0| 0| 2

    Pls modify

    /dvr_rdk/mcfw/src_bios6/links_m3video/iva_enc/encLink_common.c

    FUnction:

     Int32 EncLink_printStatistics (EncLink_Obj * pObj, Bool resetAfterPrint)

    Add call to

    System_memPrintHeapStatus();

    in this function. You should then see memory available and memory used  in different heaps.
