Provides hardware accelerated video playback from Broadwell onwards.

Older boards (e.g. Sandy Bridge) are not supported. I'm not sure if they should specifically be excluded.

More info:

Closes #99.

Sorry I missed your comment on the other thread, I don't know why I never sent it... this looks good to me too. Thanks!

I would like to verify that this doesn't break sandy bridge, but I have no way of doing so :(

I vote to merge and hope for the best. Other option is to inject /proc/cpuinfo into the configuration somehow

Should this not also enable the HuC firmware, whatever that is? https://github.com/intel/media-driver/blob/master/README.md#known-issues-and-limitations

I've got sandy bridge but my chipset doesn't support the integrated video card :/

@wmertens regarding HuC, there's some info on the Arch wiki, and a defintion of what it is here.

And a pretty nice chart of supported features on each architecture, courtesy of the Gentoo wiki.

And it seems like HuC is only required/supported from Skywell onwards?

The GuC was first introduced in Gen9 devices with the above functionalities to be introduced over time.

Which means we should make it conditional. Broadwells are still pretty common, I reckon.
