Useful to know, as with everything to do with media encoding/decoding the situation seems to be complex. > My kernels (one from Arch and one built by myself) don't try to load GuC/HuC > firmwares. /sys/kernel/debug says my iGPU doesn't need HuC, and GuC is > disabled. > OK, thanks for that. Looking a bit more deeply at what I regard as a very hard to follow set of documentation (like some others, it's probably fine if you already understand all the details) I see that HuC is only needed for Hardware Encoding, Low Power Encoding(VDEnc/Huc) on Skylake and later, but only for limited AVC and jpeg on most existing platforms. https://github.com/intel/media-driver/blob/master/docs/media_features.md#supported-video-processing-cscscaling-format ĸen -- The right of the people to keep and arm Bears, shall not be infringed. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
