151 | --show-info:: | |
152 | Display extended information about the perf.data file. This adds | |
153 | information which may be very large and thus may clutter the display. | |
154 | It currently includes: cpu and numa topology of the host system. | |

156 | -b:: |
157 | --branch-stack:: | |
158 | Use the addresses of sampled taken branches instead of the instruction | |
159 | address to build the histograms. To generate meaningful output, the | |
993ac88d SE |
160 | perf.data file must have been obtained using perf record -b or |
161 | perf record --branch-filter xxx where xxx is a branch filter option. | |
162 | perf report is able to auto-detect whether a perf.data file contains | |
163 | branch stacks and it will automatically switch to the branch view mode, | |
164 | unless --no-branch-stack is used. | |
