Low power encode through VDENC supports both CBR and VBR.
Make sure vaGetConfigAttribute correctly returns the supported
list of rate control modes in VAEntrypointEncSliceLP entrypoint.
This was intentional. I'd prefer to delay this until we get the
GuC/HuC kernel patches merged. BRC depends on the HuC firmware...
IIUC, HuC support is from BXT onwards, right?
Which means no BRC for SKL VDENC ??
https://patchwork.freedesktop.org/series/9011/
I'm also trying to get an interface (outside of debugfs) for the
driver to detect HuC FW loading
status in the revised/new patch set. We'll be reusing I915_GETPARAM
likely.
Thanks,
Sean
