System Analyzer UIA Events getting dropped

Jitendra Saini
Intellectual 270 points
Other Parts Discussed in Thread: SYSBIOS

Hi,

I have enabled System Analyzer UIA to get performance statistics. All the features work just fine but lot of Gaps are observed because of Huge number of event drops.

I am trying to use the "Context Aware Profile" feature by adding Entry Exit hook functions in Project Properties. I do get the profile results but facing the following issues - 

1) Few functions are not captured at all (Not the same functions always)

2) For the functions which gets logged, the execution count is far less than actual count. e.g. I have 2 functions which are invoked for every millisecond but the execution count remains ~1000 - 1500 after I run the system for more than 120 Seconds (actual count being 120000).

Every time I am seeing large number of UIA events (>500000 for every 60 sec) getting dropped.

I am running Only and only context aware profile (summary view) and no other UIA feature.

Below is the part of my .cfg file

var System = xdc.useModule('xdc.runtime.System');
var BIOS = xdc.useModule('ti.sysbios.BIOS');
var Swi = xdc.useModule('ti.sysbios.knl.Swi');
var Hwi = xdc.useModule('ti.sysbios.hal.Hwi');
var Task = xdc.useModule('ti.sysbios.knl.Task');
var HeapBuf = xdc.useModule('ti.sysbios.heaps.HeapBuf');
var HeapMem = xdc.useModule('ti.sysbios.heaps.HeapMem');
var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');
var Load = xdc.useModule('ti.sysbios.utils.Load');

BIOS.customCCOpts = "-mv6600 --abi=eabi -q -mi10 -mo -pdr -pden -pds=238 -pds=880 -pds1110 -o3 --program_level_compile -g --optimize_with_debug"

Program.sysStack = 8192;
Task.enableIdleTask = true;

BIOS.libType = BIOS.LibType_Custom;
BIOS.assertsEnabled = false;
BIOS.logsEnabled = true;
BIOS.cpuFreq.lo = 1000000000;
Task.idleTaskStackSize = 8192;

LoggingSetup.eventUploadMode = LoggingSetup.UploadMode_JTAGRUNMODE;
LoggingSetup.loadLoggerSize = 32768;
LoggingSetup.sysbiosLoggerSize = 32768;
LoggingSetup.mainLoggerSize = 32768;
Load.hwiEnabled = false;
Load.swiEnabled = false;
Load.windowInMs = 10;

I am using the following Hardware and Software artifacts - 

Nyquist C6670 EVM Board
SYS/BIOS 6.34
XDC Tools 3.24
C6000 Code Generation Tools v7.4.1
MCSDK 2.01

System Analyzer (UIA Target)  1.1.1.14

Please help me understand how I can get better and more reliable results from UIA.

Thanks,

Jitendra

    Hi Jitendra,

        You can reduce the number of dropouts by disabling load logging and increasing the size of your main logger.  Here is how to do this:

    In your .cfg file, change

    var Load = xdc.useModule('ti.sysbios.utils.Load');

    BIOS.customCCOpts = "-mv6600 --abi=eabi -q -mi10 -mo -pdr -pden -pds=238 -pds=880 -pds1110 -o3 --program_level_compile -g --optimize_with_debug"

    Program.sysStack = 8192;
    Task.enableIdleTask = true;

    BIOS.libType = BIOS.LibType_Custom;
    BIOS.assertsEnabled = false;
    BIOS.logsEnabled = true;
    BIOS.cpuFreq.lo = 1000000000;
    Task.idleTaskStackSize = 8192;

    LoggingSetup.eventUploadMode = LoggingSetup.UploadMode_JTAGRUNMODE;
    LoggingSetup.loadLoggerSize = 32768;
    LoggingSetup.sysbiosLoggerSize = 32768;
    LoggingSetup.mainLoggerSize = 32768;
    Load.hwiEnabled = false;
    Load.swiEnabled = false;
    Load.windowInMs = 10;

    to

    // var Load = xdc.useModule('ti.sysbios.utils.Load');

    BIOS.customCCOpts = "-mv6600 --abi=eabi -q -mi10 -mo -pdr -pden -pds=238 -pds=880 -pds1110 -o3 --program_level_compile -g --optimize_with_debug"

    Program.sysStack = 8192;
    Task.enableIdleTask = true;

    BIOS.libType = BIOS.LibType_Custom;
    BIOS.assertsEnabled = false;
    BIOS.logsEnabled = true;
    BIOS.cpuFreq.lo = 1000000000;
    Task.idleTaskStackSize = 8192;

    LoggingSetup.eventUploadMode = LoggingSetup.UploadMode_JTAGRUNMODE;
    LoggingSetup.loadLogging = false;
    LoggingSetup.sysbiosLoggerSize = 32768;
    LoggingSetup.mainLoggerSize = 65536;
    // Load.hwiEnabled = false;
    // Load.swiEnabled = false;
    // Load.windowInMs = 10;

    You can try increasing LoggingSetup.mainLoggerSize beyond 65536 if you have enough memory.

    Regards,
