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 ??
Also, what matters for "skl + vdenc + h264 enc", is GuC firmware which
is already landed in linux-firmware,
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/commit/?id=0a0c97667d0e80c56de8fd999d17bf2b553aab8f
Kernel patches are also in place in upstream kernel for GuC loading...
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
