Subject: [Xen-devel] Xen-unstable: pci-passthrough regression bisected to: x86/smp: use APIC ALLBUT destination shorthand when possible
Date: Mon, 3 Feb 2020 09:33:51 +0100 [thread overview]
Message-ID: <ebd9cf75-36cd-c064-661d-88a49445ecce@eikelenboom.it> (raw)
Hi Roger,
Last week I encountered an issue with the PCI-passthrough of a USB controller.
In the guest I get:
[ 1143.313756] xhci_hcd 0000:00:05.0: xHCI host not responding to stop endpoint command.
[ 1143.334825] xhci_hcd 0000:00:05.0: xHCI host controller not responding, assume dead
[ 1143.347364] xhci_hcd 0000:00:05.0: HC died; cleaning up
[ 1143.356407] usb 1-2: USB disconnect, device number 2
Bisection turned up as the culprit:
commit 5500d265a2a8fa63d60c08beb549de8ec82ff7a5
x86/smp: use APIC ALLBUT destination shorthand when possible
I verified by reverting that commit and now it works fine again.
Box is AMD, guest is a HVM.
