My company is using a Yocto solution (pyro) that is using meta-intel. By
default, it is using the i965 driver/vaapi. I need to switch to using iHD
for the added throughput, so that we can achieve 4k60fps.
I have followed Intel's guidance here:
https://software.intel.com/en-us/media-sdk/choose-download/embedded-iot
However, it is for jethro (older version of Yocto).
With that said, I need to find out which configuration (libraries) I should
update in my pyro solution to properly support the iHD driver.
I am finding little guidance on how to build a custom configuration that
supports iHD. There is just so many different
repors/forks/versions/dependencies, and little documentation.
I am using an i7 6th gen CPU (as 7th gen apparently isn't support by iHD).
My assumptions currently are:
- I must use a specific kernel. The supported jethro example uses 4.1. Is
this correct? Is it possible to use the 4.9 version supplied by meta-intel?
- I need to use the github.com/iotg-lin-gfx-* family of repositories. This
includes
- iotg-lin-gfx-mesa
- iotg-lin-gfx-libva
- iotg-lin-gfx-libdrm
Each of this repos contain an "m3" branch. How does this branch relate to
the iHD driver provided by intel? I'd like to use the R2.1 deliverable of
the msdk.
Another question, what is the iotg-lin-gfx-va-driver used for? It is fork
of the i965 driver? If so, why the fork?
Attached are my notes which details each configuration (supported jethro
and custom pyro).
Any help is greatly appreciated. I am currently lost in the ocean of forks
and versions! :)

Which platform are you using? What can you achieve 4K60fps for, encoding or
decoding? Could you provide the graphics PCI id?

My graphics pci id
00:02.0 VGA compatible controller: Intel Corporation Device 5912 (rev 04)
When I build the yocto Apollo lake solution, it works on my desktop (no
Apollo lake) i7 6th gen, and can encode 60fps 4k. The open source i915/i965
can only achieve 48fps on Linux. The Apollo lake solution is using the iHD
driver, which many people say it gives better throughput.
So, I would like to use the iHD driver on my custom Linux configuration. I
need guidance on what libraries/versions/forks to use to establish a
working configuration that can utilize media sdk and iHD. I will use
gstreamer-media-sdk to do the encoding.
