Linux/TDA2PXEVM: Regarding cores stress

I use cmd this 'SYSTEM_COMMON_CMD_GET_LOAD'.

Hi,

You can create a usecase grpxSrc-display.
and it will show the load of all cores.

Hi,

I'd like to up to all cores to 100%.
grpxSrc-display is fine?

I think that "while()" code should be inserted for runtime.

possible up to 80~100% for cores load.

Probably, yes you could put while(1), but please make sure to allow running other thread, which captures performance..

Hi,

I think that just insert 'while()' to each core of main.
So, I inserted the test 'while()' code in below.
(vision_sdk/links_fw/src/rtos/bios_app_common/tda2px/dsp1/src/main_common_c6xdsp2.c -> C6xDSP_main())
Is this fine?

If I run the usecase, the cores load cannot be up-to 80~100%.

After I run the 'app.out', I call the function of 'ChainsCommon_printCpuLoad()'.

The function is like below.

void ChainsCommon_printCpuLoad()
{
if(System_isProcEnabled(SYSTEM_IPU_PROC_PRIMARY))
{
System_linkControl(
SYSTEM_LINK_ID_IPU1_0,
SYSTEM_COMMON_CMD_GET_LOAD:
NULL,
0,
TRUE
);
}
if(System_isProcEnabled(SYSTEM_PROC_DSP1))
{
System_linkControl(
SYSTEM_LINK_ID_DSP1,
SYSTEM_COMMON_CMD_GET_LOAD:
NULL,
0,
TRUE
);
}
if(System_isProcEnabled(SYSTEM_PROC_DSP2))
{
System_linkControl(
SYSTEM_LINK_ID_DSP2,
SYSTEM_COMMON_CMD_GET_LOAD:
NULL,
0,
TRUE
);
}
if(System_isProcEnabled(SYSTEM_PROC_EVE1))
{
System_linkControl(
SYSTEM_LINK_ID_EVE1,
SYSTEM_COMMON_CMD_GET_LOAD:
NULL,
0,
TRUE
);
}

After the menu is shown, I call the function.
Because the code is described like below.

case SYSTEM_COMMON_CMD_GET_LOAD:
Utils_prfGetLoad(pPrm);

But the each core of the cpuload is 100%.

Hi.

I do stress cores test up-to 80~100%.

If I do test with usecase, it is difficult to up the cores to 80~100%.

So,
Without running the usecase, in task_main(), I insert the while() code for check the cpu load.

./links_fw/src/rtos/links_a15/system/systemLink_tsk_a15.c
./links_fw/src/rtos/links_dsp/system/systemLink_tsk_c6xdsp.c
./links_fw/src/rtos/links_eve/system/systemLink_tsk_eve.c

If I do command of SYSTEM_COMMON_CMD_GET_LOAD, then the Utils_prfGetLoad(pPrm) is called.

So,
After run the app.out, I input the "key" input which call the "Utils_prfGetLoad".

My code is here.

....
Void CpuLoad(){
Utils_SystemLoadStats cpuLoad;
UInt32 linkId;

if(System_isProcEnabled(SYSTEM_IPU_PROC_PRIMARY))
{
memset(&cpuLoad, 0, sizeof(cpuLoad));
linkId = IPU1_0_LINK(SYSTEM_LINK_ID_PROCK_LINK_ID);

System_linkControl(
linkId,
SYSTEM_COMMON_CMD_GET_LOAD,
&cpuLoad,
sizeof(cpuLoad),
TRUE
);
}
if(System_isProcEnabled(SYSTEM_PROC_DSP1))
{
memset(&cpuLoad, 0, sizeof(cpuLoad));
linkId = DSP1_LINK(SYSTEM_LINK_ID_PROCK_LINK_ID);

System_linkControl(
linkId,
SYSTEM_COMMON_CMD_GET_LOAD,
&cpuLoad,
sizeof(cpuLoad),
TRUE
);
}
...

If I check the cpuLoad, the cpuLoad of each core is 100%.

Please help me.

Hi,

You can put a small sleep inside while loop for each cores.
