Clicking on -> will bring as one of the popup menu options a "Zoom into CURRENT DSO", i.e. CURRENT will be replaced by the name of the DSO in the current line. Choosing this option will filter out all samples that didn't took place in a symbol in this DSO. After that the option reverts to "Zoom out of CURRENT DSO", to allow going back to the more compreensive view, not filtered by DSO. Future similar operations will include zooming into a particular thread, COMM, CPU, "last minute", "last N usecs", etc. Cc: Frédéric Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> LKML-Reference: <new-submission> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
