[Qemu-devel] [PATCH v1 0/5] Expose the secure property to the machine

[Qemu-devel] [PATCH v1 0/5] Expose the secure property to the machine

[Alistair Francis]

The EL2 and EL3 work is working well now and interanlly we now have
tests that expect to start in EL3 and transition through EL2 to EL1. To
make this easy to run let's expose the secure property to the machine
and then use that to enable EL2.

This series also does some machine/name tidying up and makes the first
move to deprecating the EP108 machine, which was just an early access
development board.

[Qemu-devel] [PATCH v1 2/5] xlnx-zcu102: Manually create the machines

[Alistair Francis]

In preperation for future work let's manually create the Xilnx machines.
This will allow us to set properties for the machines in the future.

[Qemu-devel] [PATCH v1 4/5] xlnx-zynqmp: Allow the secure prop to enable EL2

[Alistair Francis]

If the user sets the secure property to true we want to enalbe both EL2
and EL3.

The EP108 is the same as the ZCU102, mark it as deprecated as we don't
need two machines.

Hi Alistair,

Reconsidering this, I tend to agree that we're probably better off with
EL2/no-GICv2-virt compared to the possible confusiong of having EL2
without GICv2-virt..

But I wonder if we should have similar options as the virt machine?
I.e, a virtualization option to enable EL2.

Cheers,
Edgar

That's fine with me.

Just to clarify do you think we should keep the secure option for EL3
and add a virt option for EL2?

I think unless you have a really strong reason to be different
(eg back-compat with existing guests) then following what
the 'virt' board does for machine options is probably going
to be least confusing. NB that that does include letting you
specify some combos that don't work, like gicv2 + virt...

(We should really get round to implementing virt support in
the GICv2, though.)
