How do I generate an RGP profile?
|
|
=================================
|
|
|
|
RenderDoc has integration with AMD's Radeon GPU Profiler. This allows you to generate an RGP profile from a RenderDoc capture, embed the profile in the capture file, and synchronise the view of the frames between RenderDoc and RGP.
|
|
|
|
Enabling RGP integration
|
|
------------------------
|
|
|
|
By default the RGP integration is disabled. To enable it go to the :guilabel:`Settings` window and in the :guilabel:`Core` section enable :guilabel:`Enable Radeon GPU Profiler integration`.
|
|
|
|
Generating a profile
|
|
--------------------
|
|
|
|
To begin you will need to go to the :guilabel:`Tools` menu and select :guilabel:`Create new RGP Profile`. If this menu option isn't available, you need to have the latest AMD drivers installed on your machine.
|
|
|
|
Selecting this menu item will open a small popup and spend a few second creating the profile itself. After the profile is created, the RGP profiling tool will automatically open up.
|
|
|
|
.. note::
|
|
|
|
If you haven't configured the path to the RGP tool, you will be prompted to here. Once the path has been configured successfully the tool will open.
|
|
|
|
Opening a previously created profile
|
|
------------------------------------
|
|
|
|
After generating a profile above, the RGP data is embedded in the ``.rdc`` file.
|
|
|
|
Since RGP can open a profile on any machine without needing AMD drivers or hardware, this embedded RGP profile can be opened at any time by going to the :guilabel:`Tools` menu and select :guilabel:`Open RGP Profile`.
|
|
|
|
The RGP tool will open just the same as if the profile was newly created.
|
|
|
|
Correlating information between RenderDoc and RGP
|
|
-------------------------------------------------
|
|
|
|
If using RGP version 1.2 or higher, once both tools are open they have a synchronised view of the underlying data.
|
|
|
|
This means that within RGP you can select an event, right click and choose :guilabel:`Select RenderDoc Event`. This will bring RenderDoc to the foreground with the event selected. Similarly in RenderDoc you can right-click on an event in the event browser and choose :guilabel:`Select RGP Event` which will perform the same operation in reverse.

|
|
.. note::
|
|
|
|
Since RGP and RenderDoc have different scopes, purposes, and views of the frame the numbering of events will not be the same between the two tools. |
