Compiler/TDA2SX: How to debug about TDS2XX soc out of memory

user6229311

Part Number: TDA2SX

Tool/software: TI C/C++ Compiler

Hi all,

Recently, a crash problem has bothered us for a long time. It is about the crash of TDA2XX soc when running usecase that include capture, sgx3dsrv, display links, and we use gpu to proccess the 4Ch captue 2d/3d surround view, and parking space detection algorithm to realize automatic parking.Sometimes when we do automatic parking, the kernel killed the usecase(apps.out), the complete log is /cfs-file/__key/communityserver-discussions-components-files/791/20200829_5F00_1.log, we suspect that the GPU crashes when implementing 2d/3d surround view, but each crash is different.The dma, lowmem and highmen is normal, but the kernel still warned out of memory, so we do "cat /proc/meminfo" to show memory status in the log. We found our issue is similar with this https://e2e.ti.com/support/processors/f/791/p/876437/3245050#3245050, but it doesn't tell us the final solutions. Some logs about the crash are as follows, we need help, thanks very much.

Regards,

Jason

Hi,

You can find the memory leak in an application running on the Linux using Valgrind.

The example command is : valgrind --leak-check=full --log-file=log.txt ./apps.out

Refer the below links for more information

https://linux.die.net/man/1/valgrind

http://pages.cs.wisc.edu/~bart/537/valgrind.html#:~:text=Example%203%3A%20memory%20leaks,it%20will%20give%20more%20information.

Note: Before running the Valgrind command make sure the vision SDK application is built in debug mode & by default, Valgrind application is not found in vision SDK file system, so you need copy this application from the PSDKLA file system ( This application found in /usr/bin/ directory)

Thanks

Gaviraju

Hi Gaviraju,

we used the cmd to start valgrind tool before: /mnt/valgrind/bin/valgrind -q --error-limit=no --tool=memcheck --leak-check=full /opt/vision_sdk/apps.out 2 1 &

you can see the information valgrind given in the log, which started with string"==xxx==", but we did not find some valuable information. Why we can't see the function name in the log, how to show it?

Hi Gaviraju,

We also build the kernel in debug mode, the configuration is shown below, but it seems unuseful. We also set loglevel=9 in dtb file, because we use falcon mode.

Hi Gaviraju,

We use the valgrind tool before, but we want to know, when the out of memory occurs, could it be caused by this valgrind tool?Because the tool cost a lot of memory, I am worried that the memory overflow is not caused by system problems, but because of using this tool, we need to verify this.

Regards,

Jason

This could be one of the reasons, so please try to run the application without Valgrind.

Hi Karthik,

Thanks very much.Now we add debug info to the apps.out for following the PVR_T(ERROR),which is shown as below:

When we use gdb to debug the apps.out, we want to break the point at the file buffer_manager.c: L165, which is before "PVR_K:(Error): AllocMemory: BM_ImportMemory failed" report, but the gdb tell us buffer_manager.c 165 not defined(as shown below), I doubt even the apps.out is made by debug mode, but the sgx module can't be debug with it together, what shall we do? How counld we follow the PVR_K(ERROR) step by step and found the reason why it caused the error by the app?

Regards,

Jason

Hi Karthik,

We set the parameters in ~/PROCESSOR_SDK_VISION_03_06_00_00/ti_components/os_tools/linux/sgx/omap5-sgx-ddk-linux/eurasia_km/eurasiacon/build/linux2/omap_linux/Makefile, and use GDB to debug pvrsvrkm.ko, and we can break the point at the file buffer_manager.c: L165.

PVRSRV_NEED_PVR_DPF := 1
PVRSRV_NEW_PVR_DPF := 1
PVRSRV_USSE_EDM_STATUS_DEBUG := 1
PVRSRV_DUMP_MK_TRACE := 1
BUILD=debug

but when we run app, it's running error with the follow info, what's the matter about the pvr debug version?

Hi,

Whenever the SGX Kernel driver is rebuilt for different reasons such as for DEBUG mode or for adding some additional parameters, a corresponding change in the SGX User Libraries are also required. If you do not have the matching Kernel and User space driver, you will encounter this type of error.

Now, the questions are the following:

Please provide me the details the of the base SDK.
Kernel driver commit ID
SGX Kernel driver commit ID.
Source of the SGX user libs
Tool chain

We will need to provide you a corresponding user space library to help you debug further.

Also, I will request the local team to setup the file share to enable this to be delivered to you.

Regards

Karthik

Hi Jason,

The SGX user libs are located in the Yocto recipe of the filesystem and if you do not know this, then you can probably provide the md5sum of the binaries that are part of the SGX user libs and we will have to reverse match it.
