I hoped to hear more opinions because I don't really understand where to
start - I don't know much about how xen and
gt; I don't understand your concerns to the full extent. What should be
investigated?

this approach is acceptable.

UART -> crossbar -> wugen -> GIC
What do you think?

For me it looks like interrupts from crossbar goes to wugen and the from
wugen to GIC. But I don't quit

};
And this is an interrupt-parent for the crossbar. So, it is not clear
for me how it participates in interrupt processing. Any thoughts?

the same time they preserved the crossbar in the device tree. And, I
thought that you wanted to demonstrate this exact thing. Could you
describe how in general the approach with blacklisting should work?

problem if we blacklist the device? Also, the tegra
implementation blacklist only a uart.

it seems to me that it is possible to give control on the crossbar to
dom0, though, I don't really understand what's happening.

This function allows xen to bring secondary CPU cores into non-secure
HYP mode. This is done by using a Secure Monitor call.

I don't understand this since init_secondary is installed in C code,

was expelled from the program before the final evaluation and

from India felt who made an excellent project and received only $2400.
P.S. Is xen-project going to participate in Outreachy?
