WaEnableYV12BugFixInHalfSliceChicken7 [commit 0b71cea29fc29bbd8e9dd9c641fee6bd75f6827](https://cgit.freedesktop.org/drm-tip/commit/?id=0b71cea29fc29bbd8e9dd9c641fee6bd75f68274)
-3. APL: BRC functionalities requiring HuC for AVC low power encoding require 4.11 or
-later kernel to work.
+3. CNL: HEVC encoding does not support P frame.
-4. CNL: Functionalities requiring HuC including AVC BRC for low power encoding, HEVC low
-power encoding, and VP9 low power encoding require the kernel patch for GuC support to work.
+4. HuC firmware is needed for AVC low power encoding bitrate control, including CBR, VBR, etc. As of now, HuC firmware support is disabled in Linux kernels by default. Please, refer to i915 kernel mode driver documentation to learn how to enable it. Mind that HuC firmware support presents in the following kernels for the specified platforms:
+ * APL, KBL: starting from kernel 4.11
+ * CFL: starting from kernel 4.15
-5. CNL: HEVC encoding does not support P frame.
+5. Restriction in implementation of vaGetImage: Source format (surface) should be same with destination format (image).
