I read the mmiotrace.txt file on how to use the kernel functionality.
Can you tell me what actions exactly would be useful to be traced after the WM
is started.

It is written :
"During tracing you can place comments (markers) into the trace by
$ echo "X is up" > /sys/kernel/debug/tracing/trace_marker
This makes it easier to see which part of the (huge) trace corresponds to
which action. It is recommended to place descriptive markers about what you
do."
But what actions exactly to do during the trace process ?

And :
"Please, pack into a compressed archive the trace file and a free description
about what you do during the trace."
Again what is useful to do ?

Can you also precise to me the format of the name of the archive file.
"The name of the archive file should contain the PCI id and GPU family, or the
commercial name of your card."
Can you give an example of name please ?

Again :
"If you are doing a trace for a driver project, e.g. Nouveau, you should also
do the following before sending your results:
$ lspci -vvv > lspci.txt
$ dmesg > dmesg.txt
$ tar zcf pciid-nick-mmiotrace.tar.gz mydump.txt lspci.txt dmesg.txt
and then send the .tar.gz file. The trace compresses considerably. Replace
"pciid" and "nick" with the PCI ID or model name of your piece of hardware
under investigation and your nickname."
I would like an example of name of the tarball file.
