Title:
sysfs msi_irqs directory empty with kernel-5.19 when being a xen guest
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Kinetic:
In Progress
Status in linux source package in Lunar:
In Progress
Bug description:
Let's say you launch a Xen-based EC2 instance with enhanced
networking, then under kernel-5.19 you'll not see anything under
$ ls /sys/class/net/ens3/device/msi_irqs/
This can be fixed by backporting
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=335b4223466dd75f9f3ea4918187afbadd22e5c8
(It got already backported to 6.1 and 6.3)
With this patch applied, you'll correctly see the sysfs files:
$ ls /sys/class/net/ens3/device/msi_irqs/
690 691 692 693 694 695 696 697 698
