Linux/PROCESSOR-SDK-DRA7X: Using VSDK built IPU2 firmware with PSDKLA

abhijeet dixit

Part Number: PROCESSOR-SDK-DRA7X
Other Parts Discussed in Thread: DRA742, PMP, DRA752, TVP5158

Tool/software: Linux

Hello all,

I am trying to access EVEs present on Jacinto6 platform. For this purpose, I built IPU2 xem binary using VSDK and used this IPU2 xem instead of the default IPU2 xem present on the PSDKLA image. But the memory map for VSDK and corresponding PSDKLA seems to be different and hence I am getting IVA engine open failure. 

1. Is it possible to use VSDK built IPU2 xem with corresponding PSDKLA without modifications in the PSDKLA source? If not, why?

2. What are the changes needed to be done in PSDKLA source in order to be able to use the VSDK built IPU2 xem?

Used VSDK Version : VISION_SDK_02_12_02_00

Used PSDKLA Version : 3.02.00.03

    Hi Abhijeet,
    1. Yes, it should be possible to use VSDK built IPU2 xem with the corresponding PSDKLA.
    In \VISION_SDK_02_12_00_00\vision_sdk\docs\Linux\VisionSDK_Linux_UserGuide.pdf section:
    2.4.2.4 Clone ipumm
    $> cd $INSTALL_DIR/ti_components/algorithms_codecs
    $> git clone git://git.ti.com/ivimm/ipumm.git
    $> cd ipumm/
    $> git checkout -b ipumm_dev cd93550

    To build IPUMM, you also need to enable IPUMM_INCLUDE as described in:
    \VISION_SDK_02_12_00_00\vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_UserGuide_BuildSystem.pdf
    Follow sect. 4.2.1 System level config parameters on "IPUMM_INCLUDE"

    Since IPUMM build is not enabled by default from VSDK, you will need to build ipumm library before building the firmware:
    cd \VISION_SDK_02_12_00_00\vision_sdk
    [Build the IPUMM library] make ipumm
    [Build the firmware which includes the IPUMM library] make vision_sdk

    2. Changes need to be done:
    * See section 4.2 of Build configuration mentioned above, the "IPUMM_INCLUDE=yes" and "IVAHD_INCLUDE=no" and "A15_TARGET_OS=Linux".
    * Memory map configuration.
    On \VISION_SDK_02_12_00_00\vision_sdk\build\tda2xx\mem_segment_definition_1024mb_linux.xs, it defines:
    IPU2_START_ADDR = 0x94000000;
    IPU2_CODE_SIZE = 8*MB;
    if (ipummSupport == "yes") {
    IPU2_DATA_SIZE = 60*MB;
    }
    else {
    IPU2_DATA_SIZE = 20*MB;
    }
    So, the TI kernel memory allocated for IPU2 similar to \ti_components\os_tools\linux\kernel\omap\arch\arm\boot\dts\dra7-evm-infoadas.dts needs to be updated as well.
    /* Update the CMA regions for Vision SDK binaries */
    &ipu2_cma_pool {
    reg = <0x94000000 0x5000000>;
    };

    This extra memory is only used when IPUMM is enabled
    Specified in \VISION_SDK_02_12_00_00\ti_components\os_tools\linux\kernel\linux-kernel-addon\kernel-patches\0006-arm-dts-infoadas-devicetree-based-on-vision-board.patch

    If the above configuration has been done, then can you please check the remoteproc traces for IPU2?

    cat /sys/kernel/debug/remoteproc/remoteproc1/trace0

    To see if the remoteproc is giving any error trace.

    Back in Nov 4, 2016, there is a similar issue reported by Ittiam on VISION SDK 2.10 and the issue is resolved by moving the EVE_MEM memory configuration (was set to 0xBC000000) as it was conflicting with TILER memory configuration (IPU_TILER_MODE_3)

    IPUMM does use TILER memory for parameter passing, and the default values for these mappings are as follows (taken from resource table):

    #define L3_TILER_MODE_0_1 0x60000000
    #define IPU_TILER_MODE_0_1 0xA0000000

    #define L3_TILER_MODE_2 0x70000000
    #define IPU_TILER_MODE_2 0xB0000000

    #define L3_TILER_MODE_3 0x78000000
    #define IPU_TILER_MODE_3 0xB8000000

    (size of the first one is 1M and size of the last two are 128MB)

    Where is your EVE start address memory configuration?
    Thanks.

    Hi Buddy,
    Thanks a lot for the explanation and the steps. However, the steps mentioned by you are pertaining to the PSDKLA version which is bundled along with the vision SDK. I tried these changes, and after that, when I am trying to run my application, the application is being killed by OOM killer. This OOM killer issue, can be reproduced with a simple application that tries to allocate and use more than 80 MB worth of DRM buffers.

    The actual purpose of asking this question was, however, to be able to use the Vision SDK xem with a separate PSDKLA installation.
    In that case, I assumed that the xs file and dtb files corresponding to the PSDKLA installation needs changing. Therefore, I tried to find the files in PSDKLA but failed to find both. The xs file is not present in the PSDKLA.
    For the change in ipu2_cma_pool memory section that you suggested, I was able to find the section which is setting this pool in PSDKLA. The section was defined in $INSTALL_DIR/ti-processor-sdk-linux-automotive-dra7xx-evm-03.02.00.03/board-support/linux/arch/arm/boot/dts/dra7-evm.dts
    But, in the above mentioned dts, the ipu2 pool starts at a different location than visionSDK and spans for lesser memory. This might be leading to failure of insertion of ipu2 since I was not able to find /sys/kernel/debug/remoteproc/remoteproc1/trace0.
    With this complete procedure, there are still few clarifications needed:

    1. The xs files and dts files should be changed from PSDKLA or from Vision SDK?
    2. If we have to use the files from VSDK itself, how can the changes in xs file be reflected in the PSDKLA linux image?
    3. If we need to change the PSDKLA files, which files precisely need changing? What all changes are needed in those files? Is there a direct mapping to the files in PSDKLA? Or do we need to change the addresses?

    As for the eve start address, it is currently set to 0xA2000000.

    Abhijeet

    Hi Abhijeet,

    Since you mention dra7-evm.dts, that is a common dtb file. You will need to the correct device tree "dtb" used by your system: http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Automotive_Software_Developers_Guide#Choosing_the_correct_device_tree

    I am presuming that you are using J6 EVM rev.H with OSD display panel, which means you need to modify the 
    $INSTALL_DIR/ti-processor-sdk-linux-automotive-dra7xx-evm-03_02_00_03/board-support/linux/arch/arm/boot/dts/dra7-evm-lcd-osd.dts

    and match the memseg configuration done in .xs file of Vision SDK.

    If you look into how PSDKLA version which is bundled along the vision SDK for INFOADAS use case, then you will see \VISION_SDK_02_12_00_00\ti_components\os_tools\linux\kernel\linux-kernel-addon\kernel-patches\0006-arm-dts-infoadas-devicetree-based-on-vision-board.patch where it creates dra7-evm-infoadas.dts and add the cma_pool and cmem_pool for the IPU, DSP, and EVE used by Vision SDK, this will prevent Linux kernel to use those memory.

    1. It really depends on your use case, but I think it would be easier to update the PSDKLA dtb to match the memory configuration of Vision SDK. But if you are only using IPU2 and EVE and made modification on the VISION SDK memory configuration, then both PSDKLA dtb and Vision SDK memory configuration will need to be changed. Basically both needs to be matched.

    2. As mentioned above, to use the memory configuration .xs defined in Vision SDK, then you only need to make similar modification as patch 0006, by modifying PSDKLA dts to set the cma_pool and cmem_pool. That will prevent Linux kernel to use those memory used by Vision SDK and init or reset the components that are used by Vision SDK.

    3. I think you just need to modify the correct device tree and modify it similar to dra7-evm-infoadas.dts for the memory configuration and making sure thecomponents that are used by Vision SDK are not initialized or reset by Linux kernel.

    PSDKLA configuration/support team might provide other information than what I have provided.

    Thanks.

    Hi Buddy,
    Thanks for the explanation.
    Considering your points in mind, I tried to modify the dtb file of PSDKLA installation to align with VSDK. I am using a J6 EVM Rev G with LG LCD Display. So I modify dra7-evm-lcd-lg.dts with the changes done to infoadas. Keeping in mind that otherwise there are not other changes done to Vision SDK .xs file, this change should have worked. After the changes, I just did a clean build of kernel and tried to run But was faced with the same error. The error is as follows:

    MmRpc_create: Error: open failed, name=/dev/rpmsg-dce
    ../git/libdce.c:416: dce_ipc_init ERROR: Failed eError == DCE_EOK error val -4../git/libdce.c:479: Engine_open ERROR: Failed dce_ipc_init(coreIdx) == DCE_EOK error val -4../git/libdce.c:545: Engine_close ERROR: Failed engine != NULL error val -6

    Also the trace file which you told to cat is also not created and I get the following boot log.

    Any idea what I might have missed here?

    Further, When you say similar changes to PSDKLA dtb, I assumed that the way dts inclusion works and the way layout is picked up while booting is same in Vision SDK and TI_PSDKLA.
    Also, in the uenv.txt generated by clean build of PSDKLA, there was no mention of dtb file to be taken. This I added later to the uenv, before preparing the SD cart for boot.

    Thanks for the help.
    Regards,
    Abhijeet

    Hello,

    Any memory you reserved from Linux would result in reduction of available lowmem in Linux.
    DRM driver uses lowmem to allocated buffers and it'll trigger OOM if it runs out of it.

    Your problem is that the DRM memory requirement in higher.
    So I'd suggest you reduce the reserved memory for Vision SDK (Currently around 300MB) to match your usecase.
    Specially the SR1 regions is quiet high, Reduce it according to your usecase

    Accordingly change the XS file, mem_config.h (HEAP SIZE for SR) and reserved_mem in DTB
    Then you;ll see that the lowmem is increased and the OOM should not be triggered

    Regards
    Nikhil D
