OK, I applied this to the lyx master, with three changes:
Changed "filed" to "field".
Added ", or even acknowledging the feature" after "without initializing virtio queues".
Added an initial point to the Device Initialization section:
- If the VIRTIO_CONSOLE_F_EMERG_WRITE feature is offered, the
emerg_wr field of the configuration can be written at any time. Thus it should work for very early boot debugging output as well as catastophic OS failures (eg. virtio ring corruption).
Thanks for applying this patch. Have you also applied first patch ([PATCH V2 1/3] virtio: console: Add emergency writeonly register to config space) with this? (https://lkml.org/lkml/2013/5/6/169)
Would like Amit's Ack, since he's de-facto console maintainer.
I've been away, and am reviewing the discussions here. Expect a response later today.
Thanks,
Amit
