- Thread-topic: [PATCH v1 00/10] Add Xue - console over USB 3 Debug Capability
Hi,
It seems that this series has been stale for more than a month, with:
Patch #1 #2 #3 needs actions from the author.
Patch #4 reviewed.
Patch #5 to #10 needs feedback from maintainers.
So sending this email as a gentle reminder. Thanks!
Kind regards,
Henry

> This is integration of https://github.com/connojd/xue into mainline Xen.

> The driver developed by Connor supports output-only console via USB3
> debug
> capability. The capability is designed to operate mostly independently of
> normal XHCI driver, so this patch series allows dom0 to drive standard USB3
> controller part, while Xen uses DbC for console output.
>
> Changes since RFC:
> - move the driver to xue.c, remove non-Xen parts, remove now unneeded
> abstraction
> - adjust for Xen code style
> - build for x86 only
> - drop patch hidding the device from dom0
