[meta-ti][scarthgap][PATCH v3] ti-vendor-kernel-headers: add recipe for TI-only dma-heap.h ioctl

[Hari Prasath Gujulan Elango]

The TI vendor kernel's dma-heap.h carries DMA_HEAP_IOCTL_EXPORT in
downstream. The standard header provided by linux-libc-headers' wouldn't
have the custom changes.Copy it straight from the kernel's staged
source tree (STAGING_KERNEL_DIR) into a separate /usr/include/ti/linux
path instead, for userspace code that needs it.

Why do you need this dependency for do_configure? Moreover, since you don't 
have do_configure nor do_compile, you might want to mark them as "noexec"


> +do_install[depends] += "virtual/kernel:do_shared_workdir"

How do you ensure that virtual/kernel is the TI vendor kernel? If it's not, 
you'll be copying the original unmodified header into the ti/linux location.

Should this just be part of the linux-ti-staging recipes?  That way we 
can correctly only include it in the versions that have this file?

Yeah, probably the easiest and cleanest approach...

I dropped this patch and instead I added a simple do_install:append() to 
ti-linux-staging_6.12 recipe.The header doesn't get installed into the 
rootfs, but I could see it landing in the kernel-dev's ${D} output 
correctly 
(arago-tmp-default-glibc/work/j784s4_evm-oe-linux/linux-ti-staging/6.12.57+git/image/usr/include/ti/linux/). 
It doesn't get installed in the rootfs since kernel-dev package is a 
build-time-only package.

  Since the only consumer of this header is in meta-edgeai, it makes 
more sense to keep the whole thing self-contained there instead of 
modifying linux-ti-staging upstream.A linux-ti-staging_6.12.bbappend in 
that layer can install the header and split it into its own package, and 
the consuming recipe can RDEPENDS on that package directly. That keeps 
meta-ti-bsp untouched, ties the header to the recipe that actually needs 
it, and avoids shipping it into every image that happens to build this 
kernel.

Saurabh,Puyush let us know your thoughts.

Hari

BTW, just realized these patches are all marked as scarthgap ONLY. Should 
probably go the whole circle master -> wrynose -> scarthgap...

Thanks for catching this, will fix in v4. do_install() is where the 
vendor tree dependency needs to be,not in do_configure(),will drop it 
and mark it  as a noexec.I see  the cpsw9g-eth-fw_git.bb uses the same 
method.

okay so virtual/kernel can resolve to linux-ti-mainline or linux-bb.org 
or anything set by BSP_KERNEL_PROVIDER defined in per machine conf ? I 
don't have a complete understanding of how these are organized in our 
Yocto project layers. Let me check how to restrict to only the TI vendor 
kernel where this header file change is patched.
