Add new sort key 'symbol_size' to allow user to sort by symbol size, or (more usefully) display the symbol size using --fields=...,symbol_size. Committer note: Testing it together with the recently added -q, to remove the headers, and using the '+' sign with -s, to add the symbol_size sort order to the default, which is '-s/--sort comm,dso,symbol': # perf report -q -s +symbol_size | head -10 10.39% swapper [kernel.vmlinux] [k] intel_idle 270 3.45% swapper [kernel.vmlinux] [k] update_blocked_averages 1546 2.61% swapper [kernel.vmlinux] [k] update_load_avg 1292 2.36% swapper [kernel.vmlinux] [k] update_cfs_shares 240 1.83% swapper [kernel.vmlinux] [k] __hrtimer_run_queues 606 1.74% swapper [kernel.vmlinux] [k] update_cfs_rq_load_avg. 1187 1.66% swapper [kernel.vmlinux] [k] apic_timer_interrupt 152 1.60% CPU 0/KVM [kvm] [k] kvm_set_msr_common 3046 1.60% gnome-shell libglib-2.0.so.0 [.] g_slist_find 37 1.46% gnome-termina libglib-2.0.so.0 [.] g_hash_table_lookup 370 # Signed-off-by: Charles Baylis <charles.baylis@linaro.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Maxim Kuvyrkov <maxim.kuvyrkov@linaro.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1487943176-13840-1-git-send-email-charles.baylis@linaro.org [ Use symbol__size(), remove needless %lld + (long long) casting ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
