From 4aa65636411ccb12f006a6ad593930655c445ff6 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sun, 13 Dec 2009 19:50:29 -0200 Subject: perf session: Move kmaps to perf_session MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is still some more work to do to disentangle map creation from DSO loading, but this happens only for the kernel, and for the early adopters of perf diff, where this disentanglement matters most, we'll be testing different kernels, so no problem here. Further clarification: right now we create the kernel maps for the various modules and discontiguous kernel text maps when loading the DSO, we should do it as a two step process, first creating the maps, for multiple mappings with the same DSO store, then doing the dso load just once, for the first hit on one of the maps sharing this DSO backing store.
