perf ilist: Add new python ilist command The perf ilist command is a textual app [1] similar to perf list. In the top-left pane a tree of PMUs is displayed. Selecting a PMU expands the events within it. Selecting an event displays the `perf list` style event information in the top-right pane. When an event is selected it is opened and the counters on each CPU the event is for are periodically read. The bottom of the screen contains a scrollable set of sparklines showing the events in total and on each CPU. Scrolling below the sparklines shows the same data as raw counts. The sparklines are small graphs where the height of the bar is in relation to maximum of the other counts in the graph. By default the counts are read with an interval of 0.1 seconds (10 times per second). A -I/--interval command line option allows the interval to be changed. The oldest read counts are dropped when the counts fill the line causing the sparkline to move from right to left. A search box can be pulled up with the 's' key. 'n' and 'p' iterate through the search results. As some PMUs have hundreds of events a 'c' key will collapse the events in the current PMU to make navigating the PMUs easier.

perf ilist: Add support for metrics Change tree nodes to having a value of either Metric or PmuEvent, these values have the ability to match searches, be parsed to create evlists and to give a value per CPU and per thread to display. Use perf.metrics to generate a tree of metrics. Most metrics are placed under their metric group, if the metric group name ends with '_group' then the metric group is placed next to the associated metric.

perf ilist: Add support for metrics Change tree nodes to having a value of either Metric or PmuEvent, these values have the ability to match searches, be parsed to create evlists and to give a value per CPU and per thread to display. Use perf.metrics to generate a tree of metrics. Most metrics are placed under their metric group, if the metric group name ends with '_group' then the metric group is placed next to the associated metric.

perf ilist: Add support for metrics Change tree nodes to having a value of either Metric or PmuEvent, these values have the ability to match searches, be parsed to create evlists and to give a value per CPU and per thread to display. Use perf.metrics to generate a tree of metrics. Most metrics are placed under their metric group, if the metric group name ends with '_group' then the metric group is placed next to the associated metric.

perf ilist: Add new python ilist command The perf ilist command is a textual app [1] similar to perf list. In the top-left pane a tree of PMUs is displayed. Selecting a PMU expands the events within it. Selecting an event displays the `perf list` style event information in the top-right pane. When an event is selected it is opened and the counters on each CPU the event is for are periodically read. The bottom of the screen contains a scrollable set of sparklines showing the events in total and on each CPU. Scrolling below the sparklines shows the same data as raw counts. The sparklines are small graphs where the height of the bar is in relation to maximum of the other counts in the graph. By default the counts are read with an interval of 0.1 seconds (10 times per second). A -I/--interval command line option allows the interval to be changed. The oldest read counts are dropped when the counts fill the line causing the sparkline to move from right to left. A search box can be pulled up with the 's' key. 'n' and 'p' iterate through the search results. As some PMUs have hundreds of events a 'c' key will collapse the events in the current PMU to make navigating the PMUs easier.

perf ilist: Add new python ilist command The perf ilist command is a textual app [1] similar to perf list. In the top-left pane a tree of PMUs is displayed. Selecting a PMU expands the events within it. Selecting an event displays the `perf list` style event information in the top-right pane. When an event is selected it is opened and the counters on each CPU the event is for are periodically read. The bottom of the screen contains a scrollable set of sparklines showing the events in total and on each CPU. Scrolling below the sparklines shows the same data as raw counts. The sparklines are small graphs where the height of the bar is in relation to maximum of the other counts in the graph. By default the counts are read with an interval of 0.1 seconds (10 times per second). A -I/--interval command line option allows the interval to be changed. The oldest read counts are dropped when the counts fill the line causing the sparkline to move from right to left. A search box can be pulled up with the 's' key. 'n' and 'p' iterate through the search results. As some PMUs have hundreds of events a 'c' key will collapse the events in the current PMU to make navigating the PMUs easier.

Selecting a PMU expands the events within it. Selecting an event displays the `perf list` style event information in the top-right pane.

The bottom of the screen contains a scrollable set of sparklines showing the events in total and on each CPU. Scrolling below the sparklines shows the same data as raw counts. The sparklines are small graphs where the height of the bar is in relation to maximum of the other counts in the graph. By default the counts are read with an interval of 0.1 seconds (10 times per second). A -I/--interval command line option allows the interval to be changed. The oldest read counts are dropped when the counts fill the line causing the sparkline to move from right to left. A search box can be pulled up with the 's' key. 'n' and 'p' iterate through the search results. As some PMUs have hundreds of events a 'c' key will collapse the events in the current PMU to make navigating the PMUs easier.

perf ilist: Add new python ilist command The perf ilist command is a textual app [1] similar to perf list. In the top-left pane a tree of PMUs is displayed. Selecting a PMU expands the events within it. Selecting an event displays the `perf list` style event information in the top-right pane. When an event is selected it is opened and the counters on each CPU the event is for are periodically read. The bottom of the screen contains a scrollable set of sparklines showing the events in total and on each CPU. Scrolling below the sparklines shows the same data as raw counts. The sparklines are small graphs where the height of the bar is in relation to maximum of the other counts in the graph. By default the counts are read with an interval of 0.1 seconds (10 times per second). A -I/--interval command line option allows the interval to be changed. The oldest read counts are dropped when the counts fill the line causing the sparkline to move from right to left. A search box can be pulled up with the 's' key. 'n' and 'p' iterate through the search results. As some PMUs have hundreds of events a 'c' key will collapse the events in the current PMU to make navigating the PMUs easier.

perf ilist: Add support for metrics Change tree nodes to having a value of either Metric or PmuEvent, these values have the ability to match searches, be parsed to create evlists and to give a value per CPU and per thread to display. Use perf.metrics to generate a tree of metrics. Most metrics are placed under their metric group, if the metric group name ends with '_group' then the metric group is placed next to the associated metric.

perf ilist: Add support for metrics Change tree nodes to having a value of either Metric or PmuEvent, these values have the ability to match searches, be parsed to create evlists and to give a value per CPU and per thread to display. Use perf.metrics to generate a tree of metrics. Most metrics are placed under their metric group, if the metric group name ends with '_group' then the metric group is placed next to the associated metric.

perf ilist: Add support for metrics Change tree nodes to having a value of either Metric or PmuEvent, these values have the ability to match searches, be parsed to create evlists and to give a value per CPU and per thread to display. Use perf.metrics to generate a tree of metrics. Most metrics are placed under their metric group, if the metric group name ends with '_group' then the metric group is placed next to the associated metric.

perf ilist: Add new python ilist command The perf ilist command is a textual app [1] similar to perf list. In the top-left pane a tree of PMUs is displayed. Selecting a PMU expands the events within it. Selecting an event displays the `perf list` style event information in the top-right pane. When an event is selected it is opened and the counters on each CPU the event is for are periodically read. The bottom of the screen contains a scrollable set of sparklines showing the events in total and on each CPU. Scrolling below the sparklines shows the same data as raw counts. The sparklines are small graphs where the height of the bar is in relation to maximum of the other counts in the graph. By default the counts are read with an interval of 0.1 seconds (10 times per second). A -I/--interval command line option allows the interval to be changed. The oldest read counts are dropped when the counts fill the line causing the sparkline to move from right to left. A search box can be pulled up with the 's' key. 'n' and 'p' iterate through the search results. As some PMUs have hundreds of events a 'c' key will collapse the events in the current PMU to make navigating the PMUs easier.

perf ilist: Add support for metrics Change tree nodes to having a value of either Metric or PmuEvent, these values have the ability to match searches, be parsed to create evlists and to give a value per CPU and per thread to display. Use perf.metrics to generate a tree of metrics. Most metrics are placed under their metric group, if the metric group name ends with '_group' then the metric group is placed next to the associated metric.

perf ilist: Add new python ilist command The perf ilist command is a textual app [1] similar to perf list. In the top-left pane a tree of PMUs is displayed. Selecting a PMU expands the events within it. Selecting an event displays the `perf list` style event information in the top-right pane. When an event is selected it is opened and the counters on each CPU the event is for are periodically read. The bottom of the screen contains a scrollable set of sparklines showing the events in total and on each CPU. Scrolling below the sparklines shows the same data as raw counts. The sparklines are small graphs where the height of the bar is in relation to maximum of the other counts in the graph. By default the counts are read with an interval of 0.1 seconds (10 times per second). A -I/--interval command line option allows the interval to be changed. The oldest read counts are dropped when the counts fill the line causing the sparkline to move from right to left. A search box can be pulled up with the 's' key. 'n' and 'p' iterate through the search results. As some PMUs have hundreds of events a 'c' key will collapse the events in the current PMU to make navigating the PMUs easier.
