Re: [Qemu-devel] How to make memory mapped controller receive data?

[KONRAD Frederic]

Hi,

There are no CAN bus support in QEMU yet but there is some work
going on about CAN from Pavel (added in CC):
https://lists.gnu.org/archive/html/qemu-devel/2017-11/msg00104.html

He knows better than me what it does but basically the device
will be able to be contacted by other CAN devices on the bus even
outside QEMU.

If you have an SPI master _inside_ QEMU connected to your memory
mapped SPI controller you can create a qemu_timer in the device
which will send data to the SPI controller.
