Looking to use My Displaylink USB adapter. Is it possible to add UDLFB support to Yocto? I found this, but not sure how it relates.
http://git.yoctoproject.org/cgit.cgi/linux-yocto-contrib/plain/drivers/gpu/drm/udl/ /drivers/gpu/drm/udl/
I've started trying to compile my own YoctoLinux for the Edison.. In a menuconfig / defconfig file, I added
2408:CONFIG_FB_UDL=y
and
2347:CONFIG_FB=y
However, when I executed
- bitbake -c compile_kernelmodules virtual/kernel
It didn't compile the udlfb.ko driver. Is there a command to compile just the video/frame buffer hardware drivers?

Hi matbee,
Which Edison image are you using?
Did you download the Kernel modules from Alex's repo? According to an older post he added the modules some time ago. And if you check his repository, you'll be able to find it, http://repo.opkg.net/edison/repo/edison/ http://repo.opkg.net/edison/repo/edison/.
Regards,
Pablo

hi PabloM_Intel
I've tried installing this module:
edison:~# opkg install kernel-module-udlfb
Package kernel-module-udlfb (3.10.17-r0) installed in root is up to date.
However
edison:~# find / -name "*udlfb*"
/home/root/kernel-module-udlfb_3.10.17-r0_edison.ipk
/var/lib/opkg/info/kernel-module-udlfb.postrm
/var/lib/opkg/info/kernel-module-udlfb.control
/var/lib/opkg/info/kernel-module-udlfb.postinst
/var/lib/opkg/info/kernel-module-udlfb.list
/lib/modules/3.10.17-yocto-standard/kernel/drivers/video/udlfb.ko
edison:~# insmod /lib/modules/3.10.17-yocto-standard/kernel/drivers/video/udlfb.ko
insmod: ERROR: could not insert module /lib/modules/3.10.17-yocto-standard/kernel/drivers/video/udlfb.ko: Invalid module format

I realized my mistake...
I had added his repo to my edison, but didn't realize I needed a new kernel.
Replaced my kernel, and the USB HDMI DisplayLink works perfectly.
