--- Comment #18 from Xavier <[email protected]> 2011-02-06 13:36:21 PST --- (In reply to comment #17) > 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 ? > AFAIK with nouveau, you get corruption just by starting X. So I think you just need to start X with the blob, mark X is up in the trace, and stop. > 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. $ lspci -n -d 10de: 01:00.0 0300: 10de:0407 (rev a1) -> the pci id of my card is 0407 (10de is vendor id, nvidia) $ dmesg | grep generation [11562.063550] [drm] nouveau 0000:01:00.0: Detected an NV50 generation card (0x084700a2) -> generation is nv50, codename nv84. So in my case I would just call it nv84-0407-shining-mmiotrace.tar.gz -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
