EZSDK sys top Linux Utility

What is sys_top utility?

This utility is similar to linux top and called as System Top or sys_top, system shows execution status of various modules in the system namely Heaps, Shared region, etc..., One can filter the information by core id and by modules.

How to Build

1. cd utilities\sys_top
2. Edit makefile
3. Update below paths
   1. CSTOOL_PATH
   2. LDRMEMSEGCFG_PATH
4. run make
5. The executable sys_top present in the current directory

How to Execute & Execution snapshot

In the Linux prompt in target execute as below ./sys_top

Below is the execution snapshot

Filter information for given core and given module

Execute as below for VM3 core and shared region module

./sys_top -c 1 -m s

How to interpret sys_top output

From the above picture

1. System heap for HDVICP2, This is same as the "ti.sysbios.heaps.HeapMem" configuration for ".systemHeap" in the cfg file HDVICP2
2. Heap from SR0, As query at HDVICP2, same as item7, but there could be difference is run time values as the query time at HDVPSS and HDVICP2 could be different, but the size and Physical address's are same, also same as SharedRegion.setEntryMeta configuration present in the cfg file.
3. . Heap from SR1, As query at HDVICP2, same as item8, but there could be difference is run time values as the query time at HDVPSS and HDVICP2 could be different, but the size and Physical address's are same, also same as "IPC_SR_VIDEO_M3_VPSS_M3" in memsegdef_default.c present in firmware loader.
4. . Heap from SR2, As query at HDVICP2, same as item9, but there could be difference is run time values as the query time at HDVPSS and HDVICP2 could be different, but the size and Physical address's are same, also same as "IPC_SR_FRAME_BUFFERS" in memsegdef_default.c present in firmware loader.
5. . System heap for HDVPSS, This is same as the "ti.sysbios.heaps.HeapMem" configuration for ".systemHeap" in the cfg file HDVICP2
6. . Internal heap for HDVPSS, This is same as VIDEO_M3_INT_HEAP_CACHED
7. . Heap from SR0, As query at HDVPSS, this is same as item2,
8. . Heap from SR1, As query at HDVPSS, this is same as item3,
9. .. Heap from SR2, As query at HDVPSS, this is same as item4,

Note: The internal heap (ie. "VIDEO_M3_INT_HEAP_CACHED") for HDVICP2 is not being displayed by sys_top, this would be fixed in future releases.

Note

1. Show firmware version information's of MC.HDVICP2 and MC.HDVPSS is available from EZSDK 05.03.00.09 onwards.

Note

1. Show firmware version information's of MC.HDVICP2 and MC.HDVPSS is available from EZSDK 05.03.00.09 onwards.

Features planned

1. Heart Beat of each slaves
2. Add Thread load information
3. Add Heapname in the sys_top utility
