Subject: 5.10 regression, many XHCI swiotlb buffer is full / DMAR: Device bounce map failed errors on thunderbolt connected XHCI controller
Date: Tue, 10 Nov 2020 12:36:47 +0100	[thread overview]
Message-ID: <b046dd04-ac4f-3c69-0602-af810fb1b365@redhat.com> (raw)

Hi All,

Not sure if this is a XHCI driver problem at all, but I needed to start
somewhere with reporting this so I went with:

scripts/get_maintainer.pl -f drivers/usb/host/xhci-pci.c

And added a Cc: linux-pci@vger.kernel.org as bonus.

I'm seeing the following errors and very slow network performance with
the USB NIC in a Lenovo Thunderbolt gen 2 dock.

Note that the USB NIC is connected to the XHCI controller which is
embedded inside the dock and is connected over thunderbolt!

So the errors are:

[ 1148.744205] swiotlb_tbl_map_single: 6 callbacks suppressed

etc.

This happens as soon as I generate any serious amount of outgoing network traffic. E.g. rsyncing files
to another machine.

Regards,

Hans
