[OE-core v2 PATCH 0/5] aarch64 changes for meta layer

[OE-core v2 PATCH 0/5] aarch64 changes for meta layer

[Naresh Bhat]

I am adding the support of aarch64 to LUV OS Distribution project.
The luv-yocto project is based on poky distribution.

https://01.org/linux-uefi-validation

While adding support I find that these are the few meta layer changes,
which I have been asked to upstream. If we merge these changes into
openembedded-core it will be more helpful to maintain the minimum set
patches at dependency projects like luv-yocto.

Changes since V0:[RFC series]
- grub: grub-efi: bootimg: Include all the chages suggested by Bernhard Reutner-Fischer
- grub: Add grub recipe changes suggested by Burton Ross

Changes since V1:
- grub: More documentation on grub recipe and remove CACHED_CONFIGUREVARS as suggested by Richard Purdie 
- bootimg: Add NOISO as suggested by Bernhard Reutner-Fischer
- syslinux: Impliment as suggested by Richard Purdie

[OE-core v2 PATCH 2/5] syslinux: Remove bootimg dependency on aarch64

[Naresh Bhat]

Remove the bootimg dependency as syslinux for aarch64. The reason to skip the syslinux package
- syslinux package contains x86 assembly code. Hence it cannot be compiled on aarch64.
- There is no BIOS on aarch64 to answer syscalls.

[OE-core v2 PATCH 3/5] bootimg: Skip iso image build on aarch64

[Naresh Bhat]

To generate bootable ISO image the x86 architecture uses syslinux package (syslinux/isolinux.bin).
We have already skip the syslinux package on aarch64.  Hence skip the iso image build on aarch64.

[Naresh Bhat]

[OE-core v2 PATCH 5/5] grub: Update grub git recipe

[Naresh Bhat]

Update the grub git recipe with the following actions for native and target

- Base class extend to native

This is required because on aarch64 we need native recipe to be compiled for host architecture and generate grub-mkimage, which is
executed on host machine to generate grubaa64.efi binary for target architecture. In the case of x86/x86_64 architecture
it does not make any difference because host=target. The flow on aarch64 is as below

grub-native compile for host (generates grub-mkimage) ==> do_install_append_class-target() generates grubaa64.efi binary by executing host executable binary grub-mkimage ==> do_deploy() deploy the grubaa64.efi

Hence add the below lines

+DEPENDS_class-target += "grub-native"
+BBCLASSEXTEND = "native"

- Add autotools-brokensep

The recipe is fails to work (because B!=S) when I have add this recipe to luvOS, hence inherit autotools-brokensep instead of autotools.
May be this needs to be fixed.

- On x86 architecture the recipe builds only for PC, It may be required to extend this recipe.

how does that help !COMPATIBLE_HOST (of syslinux) except aarch64?

I meant you to
def mycheck(d):
  h = d.getVar('COMPATIBLE_HOST', True)
  if h:
    t = d.getVar('TARGET_ARCH', True)
    if re.match(h, t):
      return 0
  return 1

and use that to set NOISO ?= "${@mycheck(d)}"
(modulo typos and testing)

I think something like that should work and i think this would be
preferable to adding all those upcoming NOISO_baz
See what i mean?

thanks,

I have implemented and tried it with luvOS distribution.

def check_iso_build(d):
       host = d.getVar('COMPATIBLE_HOST', True)
       if host:
            import re
            target = d.getVar('TARGET_ARCH', True)
            if re.match(host, target):
                return 0
       return 1

NOISO ?= "${@check_iso_build(d)}"


For the following reason

The COMPATIBLE_HOST value is NULL.  Now the question is why it contains
value NULL.  That's simply because syslinux recipe does not inherit
bootimg.bbclass.

I did following experiment - The luv-live-image.bb inherit the
bootimg.bbclass hence I have defined the COMPATIBLE_HOST as "x86" or
"aarch64" depending on the build I am doing. This will work for x86
architecture but definitely going to break for aarch64  because of the
below condition

if re.match(host, target):
                return 0

Let me know If I need to experiment/change the logic of the implementation.

Unfortunately bitbake does not currently allow for inter-package interrogation.
Your distro should (IMHO) set NOISO appropriately (like in that func) and the IMG.bbclass should honour that decision.

HTH,

Ping, If any of the patches makes sense (out of 5) please pick up in
1.9 release.  If something which does not make sense let me know.  I
will try to re-work on it according to requirement.

I will be on vacation rest of the week and get back on your response
on Monday 15th June.

Thanks
