Hi,

I would like to emulate and evaluate i.MX8MQLite performance with MCIMX8M-EVK.

How can I disable VPU?

I checked defconfig but nothing found.
https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/configs/defconfig?h=imx_4.14.98...

For instance, is it OK to play video with software decoder plugin instead of VPU plugin?

Can anybody help me?

you don't need to disable vpu, if you need use software decoding, you can use libav(open source), but I don't know why you use software deocoding since imx8M has hardware decoding?

for how to install the libav, pls refer to the steps as below:

The following steps show how to install gstreamer1.0-libav into a rootfs image.
1. Add the following lines into the configuration file conf/local.conf.
IMAGE_INSTALL_append = " gstreamer1.0-libav"
LICENSE_FLAGS_WHITELIST = "commercial"
2. Build gstreamer1.0-libav.
$ bitbake gstreamer1.0-libav
3. Build the rootfs image.
$ bitbake
$ <image_name>
