[PATCH 0/1] oeqa: drop support of listing machines in QEMU_USE_KVM

[Chen Qi]

Hi Yeoh Ee Peng,

meta/lib/oeqa/manual/bsp-qemu.json might need to be modified after this patch.
But I don't know how it is used. Could you please help take care of it?

Best Regards,
Chen Qi

[PATCH 1/1] oeqa: drop support of listing machines in QEMU_USE_KVM

[Chen Qi]

We want QEMU_USE_KVM to only set to some boolean value, with possible
MACHINE override. Drop the support of listing machines in this variable,
and give users error message if they still do so.

Error message below is an example.

ERROR: core-image-minimal-1.0-r0 do_testimage: Invalid boolean value 'intel-corei7-64 intel-core2-32 qemux86 qemux86-64'
QEMU_USE_KVM needs to be set to a boolean value. It no longer supports accepting a list of machines.
  e.g.
    QEMU_USE_KVM_qemux86-64 = '1'
    ERROR: core-image-minimal-1.0-r0 do_testimage: Function failed: do_testimage

This drops the x86 piece above. The autobuilder sets:

QEMU_USE_KVM = "True"

which then fails for say qemuarm.

The x86 check is incorrect anyway, it needs to check the BUILD_ARCH is
compatible with TARGET_ARCH.

We can't quite merge this as is though due to the autobuilder breakage.

Cheers,

Richard
