### Filtering
To reduce profiling time and the counters collected one may use profiling filters. Profiling filters and their functionality depend on the underlying profiler being used. While Omniperf is profiler agnostic, we've provided a detailed description of profiling filters available when using Omniperf with [rocProfiler](https://rocm.docs.amd.com/projects/rocprofiler/en/latest/rocprof.html) below.

#### IP Block Filtering
One can profile a selected IP Block to speed up the profiling process. All profiling results are accumulated in the same target directory, without overwriting those for other IP blocks, hence enabling the incremental profiling and analysis.
#### Hardware Component Filtering
One can profile specific hardware components to speed up the profiling process. In Omniperf, we use the term IP block to refer to a hardware component or a group of hardware components. All profiling results are accumulated in the same target directory, without overwriting those for other hardware components, hence enabling the incremental profiling and analysis.
The following example only gathers hardware counters for SQ and TCC, skipping all other IP Blocks:

### Standalone Roofline

If you are only interested in generating roofline analysis data try using `--roof-only`. This will only collect counters relevant to roofline, as well as generate a standalone .pdf output of your roofline plot.
Standalone Roofline Options:
- The `--sort` \<desired_sort> allows you to specify whether you'd like to overlay top kernel or top dispatch data in your roofline plot.
- The `--sort` \<desired_sort> allows you to specify whether you would like to overlay top kernel or top dispatch data in your roofline plot.
- The `-m` \<cache_level> allows you to specify specific level(s) of cache you'd like to include in your roofline plot.
- The `-m` \<cache_level> allows you to specify specific level(s) of cache you would like to include in your roofline plot.
- The `--device` \<gpu_id> allows you to specify a device id to collect performace data from when running our roofline benchmark on your system.
- If you'd like to distinguish different kernels in your .pdf roofline plot use `--kernel-names`. This will give each kernel a unique marker identifiable from the plot's key.
