Creating image with genericx86 machine and RT-Preempt Patch

Creating image with genericx86 machine and RT-Preempt Patch

Hi,

I try to build an image for a x86 architecture with RT-Preemtp Patch. So I use the genericx86 machine and try to build the core-image-rt recipe. This fails with the following errors:

> ERROR: Nothing PROVIDES 'linux-yocto-rt' (but /media/disk/myYocto/poky/meta/recipes-rt/images/core-image-rt.bb DEPENDS on or otherwise requires it)
> ERROR: linux-yocto-rt was skipped: incompatible with machine genericx86 (not in COMPATIBLE_MACHINE)
> ERROR: Required build target 'core-image-rt' has no buildable providers.
> Missing or unbuildable dependency chain was: ['core-image-rt', 'linux-yocto-rt']

So I add the following parameter to my local.conf file:

> COMPATIBLE_MACHINE_genericx86 = "genericx86"
> COMPATIBLE_MACHINE_quilt-native = "genericx86"
> PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt"

But I get this error:

> ERROR: Task 80 (/media/disk/myYocto/poky/meta/recipes-kernel/linux/linux-yocto-rt_3.14.bb, do_compile) failed with exit code '1'

In the log.do_compile file I see:

> NOTE: make -j 4 bzImage CC=i686-poky-linux-gcc  LD=i686-poky-linux-ld.bfd

I already tried genericx86_64 machine and it's still not working. Are the genericx86 machine incompatible with the core-image-rt recipy? If yes how can I build a x86 image with the RT patch?

Many Thanks

What you did should have worked, since we do map the genericx86 BSP onto
one of the configurations that supports preempt-rt.

It looks like a compile error has crept in .. I'll start a build and see
if it is indeed broken at the moment (and then I can fix it).

Assuming you are building with yocto/poky, you need the following patch.
(note: this is configure tested only).

Since without this bbappend, we don't have genericx86 mapped to a valid
linux-yocto BSP and commit hash.

I'll be sending this change for merging into the project shortly.

Bruce
