Re: [Qemu-devel] [PATCH for-2.12 0/2] RISC-V: Mark FP status dirty

[Michael Clark]

Hi Richard,

Thanks! I'll test this tomorrow morning and we can choose whether to
include your proper fix or the workaround.

I think we have time assuming we send out PRs tomorrow.

Given our important fixes have review including either this fix by tomorrow
or the workaround, and Philippe has reviewed our other important bugs
fixes, then we should be fine.

Then after getting the critical and important fixes out of the way, then I
perhaps make a PR for the other reviewed changes, although these might best
wait until QEMU 2.13 opens.

Thanks again,
Michael.
