I can see there is a fixed set of 512 system reserved and 512
user-defined events. The total size of the record i item is 32 bits
out of which 10 bits are allocated to the event and 22 bits are
allocated to timestamps. The record item is defined in two formats 32
and 64 bits.
Yes, the target depends if the data member is 32-bits or 64-bits. The
reason for this is that we need enough space to store pointers.
With the Qemu simulation you set up during the project proposal,
you are
able to get a TCP stream of record items from the Qemu target to your
host. You also have an example client which sorts this stream,
determines the timestamps and prints the items.
The stream print function is defined at
rtems-tools/misc/record/record-main.c inside function "static void
print_item( FILE *f, const client_item *item )". This function prints
the TCP stram.
Yes.
Your job is now to convert the record item stream into a CTF stream.
In order to convert to CTF, we need to know the structure of it. I
followed this page https://diamon.org/ctf/. The CTF stream packet has
three major parts header, context, concatenated events(header,
stream-specific context, event-specific context, payload).
Yes.
*I would like to point out one thing that I recently pulled the
rtems-libbsd and tried to build it again. The build fails due to
recent commits made in the master branch(after the commits "Update due
to API changes").*
If you update rtems-libbsd, then also update rtems and build the BSP
again, then build the libbsd.
