adb shell atrace -c -b 10240 --async_start -z gfx 

atrace: invalid option -- h

usage: atrace [options] [categories...]

options include:

  -a appname      enable app-level tracing for a comma separated list of cmdlines; * is a wildcard matching any process

  -b N            use a trace buffer size of N KB

  -c              trace into a circular buffer

  -f filename     use the categories written in a file as space-separated

                    values in a line

  -k fname,...    trace the listed kernel functions

  -n              ignore signals

  -s N            sleep for N seconds before tracing [default 0]

  -t N            trace for N seconds [default 5]

  -z              compress the trace dump

  --async_start   start circular trace and return immediately

  --async_dump    dump the current contents of circular trace buffer

  --async_stop    stop tracing and dump the current contents of circular

                    trace buffer

  --stream        stream trace to stdout as it enters the trace buffer

                    Note: this can take significant CPU time, and is best

                    used for measuring things that are not affected by

                    CPU performance, like pagecache usage.

  --list_categories

                  list the available tracing categories

 -o filename      write the trace to the specified file instead

                    of stdout.
