Michael,

could you merge it through RISCV queue?

Yes indeed. Sorry I missed this email.

I'm going to bring this into the riscv-qemu queue right away and move it to
the head of the queue, now we have Alastair's stuff in master. Although I
won't be making any PRs until after 3.0 is released.

I'm currently re-basing and testing the RISC-V tree against Alastair's
changes. There were quite a few conflicts so it is going to take a bit of
testing. I also need to spend some time re-testing master.

I've been AWOL for the last month and a half due to some work related to
SiFive's new E20 and E21 cores which were recently announced. In the QEMU
3.1 or 3.2 time-frame we should have the new CLIC interrupt controller
which supports multiple levels of interrupt pre-emption, interrupt tail
chaining and new vectored interrupt modes. In the proposed CLIC spec (Core
Level Interrupt Controller), pre-emption is mostly handled in software but
there is a tiny bit of hardware support. We don't have any magic hardware
state machines that save multiple registers at a time. The proposed CLIC
sticks pretty closely to a set of RISC-V ideals with respect to how much is
done in a micro-op in the ISA and avoidance of complex hardware state
machines (e.g. no wiring of the ABI caller save registers into hardware).
I'm currently working on test cases for the CLIC and hopefully SiFive will
have tests for other changes we have in the RISC-V tree, so we have
"proofs" accompanying each patch that makes any sufficiantly complex
change. It of course will take a bit of time for us to accompany each of
our changes with a test. SiFive do actually have resources devoted to
formal verification but I have not yet been able to convince them to devote
resources to formally verifying the RISC-V QEMU implementation. Anyway we
do at least hope to have some tests for the RISC-V QEMU target in the near
future...

Phillipe, I noticed the recent cross complier infrastructure support so we
could potentially bring in riscv-tests as a submodule in QEMU... this will
help...

Michael.

Thanks, it's cleanup so it's ok if it goes to 3.1
