[yocto] yocto on zynq, How to configure kernel to include drivers

[Hecht, Martin (Silica)]

Hi Toby,

Please compare with http://www.wiki.xilinx.com/Linux+Drivers. Most of the DMA drivers aren't mainlined by now. You need to add them by yourself currently.

Regards,
Martin

Subject: [yocto] yocto on zynq, How to configure kernel to include drivers

I'm quite new to yocto so still have a lot to learn. I'm trying to include the DMA drivers in my yocto build for a Zynq based on the meta-xilinx layer (http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/).

I thought I'd be able to add them in the kernel configuration
(menuconfig) by running (from within the build directory):

bitbake linux-xlnx -c kernel_configme -f bitbake linux-xlnx -c menuconfig

I can't see the DMA drivers in menuconfig. However if I run menuconfig within the linux-xlnx tree (which is referenced by the SRCURI) I can see the DMA drivers. Is there some reason they're hidden in the build menuconfig?

Thanks,
Toby
