More records can be fetched using the Fetch bar provided. 2998<h3>Disassembly</h3> 2999Open a branch to display disassembly. This only works if: 3000<ol> 3001<li>The disassembler is available. Currently, only Intel XED is supported - see <a href=#xed>Intel XED Setup</a></li> 3002<li>The object code is available. Currently, only the perf build ID cache is searched for object code. 3003The default directory ~/.debug can be overridden by setting environment variable PERF_BUILDID_DIR. 3004One exception is kcore where the DSO long name is used (refer dsos_view on the Tables menu), 3005or alternatively, set environment variable PERF_KCORE to the kcore file name.</li> 3006</ol> 3007<h4 id=xed>Intel XED Setup</h4> 3008To use Intel XED, libxed.so must be present. To build and install libxed.so: 3009<pre> 3010git clone https://github.com/intelxed/mbuild.git mbuild 3011git clone https://github.com/intelxed/xed 3012cd xed 3013./mfile.py --share 3014sudo ./mfile.py --prefix=/usr/local install 3015sudo ldconfig 3016</pre> 3017<h3>Instructions per Cycle (IPC)</h3> 3018If available, IPC information is displayed in columns 'insn_cnt', 'cyc_cnt' and 'IPC'. 3019<p><b>Intel PT note:</b> The information applies to the blocks of code ending with, and including, that branch. 3020Due to the granularity of timing information, the number of cycles for some code blocks will not be known. 3021In that case, 'insn_cnt', 'cyc_cnt' and 'IPC' are zero, but when 'IPC' is displayed it covers the period 3022since the previous displayed 'IPC'. 3023<h3>Find</h3> 3024Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match. 3025Refer to Python documentation for the regular expression syntax. 3026All columns are searched, but only currently fetched rows are searched. 3027<h2 id=selectedbranches>1.4 Selected branches</h2> 3028This is the same as the <a href=#allbranches>All branches</a> report but with the data reduced 3029by various selection criteria. A dialog box displays available criteria which are AND'ed together. 3030<h3>1.4.1 Time ranges</h3> 3031The time ranges hint text shows the total time range. Relative time ranges can also be entered in 3032ms, us or ns. Also, negative values are relative to the end of trace. Examples: 3033<pre> 3034 81073085947329-81073085958238 From 81073085947329 to 81073085958238 3035 100us-200us From 100us to 200us 3036 10ms- From 10ms to the end 3037 -100ns The first 100ns 3038 -10ms- The last 10ms 3039</pre> 3040N.B. Due to the granularity of timestamps, there could be no branches in any given time range. 3041<h2 id=topcallsbyelapsedtime>1.5 Top calls by elapsed time</h2> 3042The Top calls by elapsed time report displays calls in descending order of time elapsed between when the function was called and when it returned. 3043The data is reduced by various selection criteria. A dialog box displays available criteria which are AND'ed together. 3044If not all data is fetched, a Fetch bar is provided. Ctrl-F displays a Find bar. 3045<h1 id=tables>2. Tables</h1> 3046The Tables menu shows all tables and views in the database. Most tables have an associated view 3047which displays the information in a more friendly way. Not all data for large tables is fetched 3048immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted, 3049but that can be slow for large tables. 3050<p>There are also tables of database meta-information. 3051For SQLite3 databases, the sqlite_master table is included. 3052For PostgreSQL databases, information_schema.tables/views/columns are included. 3053<h3>Find</h3> 3054Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match. 3055Refer to Python documentation for the regular expression syntax. 3056All columns are searched, but only currently fetched rows are searched. 3057<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous 3058will go to the next/previous result in id order, instead of display order. 3059""" 3060 3061# Help window
