The files in this directory help with testing Virgl on the virtio-gpu winsys
|
|
by means of Crosvm.
|
|
|
|
A whole environment will be built in a Docker image, then Mesa and Virglrenderer
|
|
will be built from local directories to be used both in the host and the guest.
|
|
|
|
The container image builds on top of other images built by scripts in the crosvm repository.
|
|
|
|
Instructions for building base images:
|
|
|
|
```console
|
|
$ git clone https://chromium.googlesource.com/chromiumos/platform/crosvm
|
|
$ pushd crosvm
|
|
$ sh docker/build_crosvm_base.sh
|
|
$ sh docker/build_crosvm.sh
|
|
```
|
|
|
|
Instructions for building target image:
|
|
|
|
```console
|
|
$ cd virglrenderer
|
|
$ sh perf-testing/build-dockerimage.sh
|
|
```
|
|
|
|
Instructions for running the container:
|
|
|
|
```console
|
|
$ cd virglrenderer
|
|
$ bash perf-testing/run_trace-in-container.sh \
|
|
--root $PATH_THAT_CONTAINS_MESA_CHECKOUT_VIRGLRENDERER_AND_TRACES_DB_CHECKOUT \
|
|
--trace $API_TRACE_TO_RUN
|
|
```
|
|
|
|
There are also options for run_trace-in-container.sh that allow specifying the
|
|
path to mesa, virglrenderer, and the traces db. These override the root path.
|
|
In addition, the root path defaults to the current working directory.
|
|
|
|
As a conveniance for shell autocompletion users running the script from the default
|
|
root that contains the traces db as subdirectory the the trace file name can be
|
|
also given with this traces db sudirectory name, i.e. if the traces db is located
|
|
in '$workdir/traces-db', root=$workdir, and the trace is calles 'sometrace.trace',
|
|
then both commands
|
|
```
|
|
perf-testing/run_trace-in-container.sh -r $rootdir -t traces-db/sometrace.trace
|
|
```
|
|
and
|
|
```
|
|
perf-testing/run_trace-in-container.sh -r $rootdir -t sometrace.trace
|
|
```
|
|
will work equally.
|
|
|
|
At the moment of writing, the branch perfetto-tracing is needed for mesa at
|
|
commit ec4277aea63cf3, and the for virglrenderer at least commit
|
|
"perf: compile mesa with perfeto support" is needed so that these projects
|
|
emit the required traces.
|
|
|
|
The perfetto traces will be saved to the a subdirectory of the traces-db checkout
|
|
directory with a name based on the api trace passed in with the --trace parameter.
|
|
|
|
Once the run_trace-in-container.sh script finishes, 3 Perfetto trace files will be written:
|
|
$(API_TRACE_TO_RUN%.*}-host.perfetto, $(API_TRACE_TO_RUN%.*}-guest.perfetto
|
|
and $(API_TRACE_TO_RUN%.*}-summary.perfetto. The last one is the fusion of the two first.
|
|
|
|
In order to visualize the traces, the Perfetto UI needs to be running in a local
|
|
service which can be started as follows:
|
|
|
|
```console
|
|
$ perf-testing/perfetto-ui.sh
|
|
```
|
|
|
|
The Perfetto UI can be loaded then on Chromium on the http://localhost:10000 address.
