Re: [QEMU][PATCH 2/5] hw/net/can: Introduce Xilinx Versal CANFD controller

[Pavel Pisa]

Hello Peter,

thanks for the review and Vikram for his work, I do not know
much about Xilinx emulation nor Xilixn CAN controllers so I cannot
comment much on this part.

The actual generated documentation is located at

  https://www.qemu.org/docs/master/system/devices/can.html

I think that that URL is stable for some time... Could it
be used directly in source to provide path to formated version?

Some short example how to use emulation even with Xilinx Zynq and Ultra Scale
would be nice if added into the document. If the document length expands
too much, then probably division into individual documents per controllers
would be nice.

By the way, CAN in Automation publishes our overview article about our CAN
activities including some short netion of QEMU integration

I hope I wind some time for CAN in QEMU, RTEMS and Linux ongoing projects,
but I need to finish some promissed project for ESA the first.

Best wishes,

                Pavel
