LOG manager implicit instrumentation APIs

Chi Tran

How can I obtain the LOG manager implicit instrumentation APIs ?

and find out the LOG object / buffer internal data structure ?

I am trying to implement a Linux software tool that can read the user defined LOG buffer in the DSP/BIOS, and display the log messages on the Linux console.

As shown in Figure 3-2 in the "SPRU423F" DSP/BIOS User's Guide, section 3.3.2 page 3-8:

" ... LOG buffers are read from the target and stored in a much larger buffer on the host. Records are marked empty as they are copied up to the host. "

I think the CCS plug-in (DSP/BIOS --> Message Log) running on windows is interfacing with the LOG manager implicit instrumentation APIs for retrieving the log messages from the log buffer. I would like to implement the same feature (limited to only user-defined logs) but on Linux platform.

Thanks,

Is this what you are looking for?

It is what I am looking for. However, the wiki does not provide enough information for one to iterate through the log buffer entries.

It describes the log buffer data elements (seqnum, arg0, arg1, format string) very well.

But it is lacking interface information on how to iterate the log buffer entries. How to get the begin entry, get the next entry, and determine current log entry (that has just been filled by LOG_Event or LOG_printf).

Thanks,
