[yocto] Where is the emgd.ko module?

[autif khan]

I think that I did. Included is an excerpt that says that I need not
do anything except bitbake core image sato when MACHINE="crownbay".

As instructed, I followed the steps in section one (Building the
meta-crownbay BSP layer) and ignored everything in section two
(Special notes for building the meta-crownbay BSP layer) which
includes instructions to patch a "crownbay-noemgd" with the Intel
driver.

Included below is the excerpt from the README. Is there a section that
I am overlooking?

Thanks

Autif

The meta-crownbay layer makes use of the proprietary Intel EMGD
userspace drivers when building the "crownbay" machine (but not when
building the "crownbay-noemgd" machine).  If you got the BSP from the
'BSP Downloads' section of the Yocto website, the EMGD binaries needed
to perform the build will already be present in the BSP, located in
the meta-intel/common/recipes-graphics/xorg-xserver/emgd-driver-bin-1.8
directory, and you can ignore the rest of this section.
