Re: [Qemu-devel] [PATCH v1 00/22] target-arm: Preparations for A64 EL2 and 3

[Aggeler Fabian]

Hi

I’ve been reworking the Samsung patches as part of my Master thesis and I 
wanted to send them some time this week. I am currently rebasing them when I 
noticed Edgar’s patches. Is there some branch with the patches so I could 
rebase on them?

Thanks,
Fabian

Hi,

I've been doing some work on modeling parts of EL2 and 3 + some of
the system-wide virtualization features for ARMv8. A lot is missing
but I've got a series with enough to for example run KVM A64 guests
on top of EL3 firmware inside emulated QEMU A64 VMs.
I'm working on cleaning things up and plan to send patches and publish
things as I go.

So before I start reviewing this, how does it relate to the
Samsung series for AArch32 trustzone (EL3) support that was
posted last year? In Linaro we've been planning to rework that
and integrate it upstream...


Hi Peter,

AFAICT the series have some minor overlap but mostly they complement each other.
The aarch64 EL3 support I've got so far is very limited. Has mode switching,
separate page tables, SMC etc and that kind of things but no S/NS state yet.
The A64 security state parts can be implemented on top of the Samsung series.

Cheers,
Edgar
