[Qemu-devel] [PATCH v2 6/6] riscv64-softmmu.mak: Build Virtio Block support
Posted by Alistair Francis 7 years, 7 months ago
Add build time support for the VirtIO block device. This allows us to
attach a drive using the virtio-blk-device.

I’m not sure what has changed in master, but VirtIO block and net for both
softmmu-riscv32 and softmmu-riscv64 were previously building by default and
working. Perhaps i’ve missed some patches that split up VirtIO support into
more granular config options.

In any case, we should enable both CONFIG_VIRTIO_NET and CONFIG_VIRTIO_BLK
for both riscv32 and riscv64 as these were working in QEMU 2.12. There are
folk using the “virt” machine for riscv32 Linux.

Thanks, at least I know what to expect when I rebase my patch queue against
master and of course make a PR for the reviewed patches...

I’m not sure of the soft-freeze date but the bulk of the patches are the
same ones that were posted about a month ago... I also have several patches
that are not yet on the list...

Vectored interrupts. Trap tracing. More spec wording clarifications
regarding load reservations and interrupts:

It just occurred to me that this patch might not be required. Someone
my last patch series had a conflict that results in removing the virt
include in the default configs. I suspect this patch can be dropped.
