Re: Kernel Header UAPI Issue

Karthik Poduval #52454 Hi Mikko, Do you have an example on how you do that ? Do you bbapend the linux-libc-headers recipe file ? I have an application that uses dmabuf heap that potentially extends across multiple BSP's as its BSP agnostic. I don't want to be patching individual BSP recipes and generating headers. The issue I am facing is due to backporting the patch from 5.6 to 5.4 so the required header isn't a part of the linux-libc-headers.bb recipe. Best would have been a virtual/kernel-keaders target that applications that require BSP headers would add to their recipe DEPENDS. Why is this not a solved issue by yocto project ? Why do individual BSP's need to deal with this differently when the header install mechanism (make headers_install) is the same irrespective of the type of BSP ? toggle quoted messageShow quoted text On Tue, Feb 23, 2021 at 5:18 AM <Mikko.Rapeli@...> wrote: Hi, I know it's not the best or recommended approach, but I find it hard to avoid merging linux-libc-headers recipe with the actual kernel recipe that a distro is using. At least a static copy of some version of uapi headers from that kernel can be used instead of the poky side linux-libc-headers. This helps to get the actual BSP SW delivery headers into userspace, SDK etc. Cheers, -Mikko -- Regards, Karthik Poduval
