The avoid WARN splats and a performance issue with interdomain events. Patches 4 and 5 are some additions to event handling in order to add some per pv-device statistics to sysfs and the ability to have a per backend device spurious event delay control. Patches 6 and 7 are minor fixes I had lying around. Juergen Gross (7): xen/events: reset affinity of 2-level event initially xen/events: don't unmask an event channel when an eoi is pending xen/events: fix lateeoi irq acknowledgement xen/events: link interdomain events to associated xenbus device xen/events: add per-xenbus device event statistics and settings xen/evtch: use smp barriers for user event ring xen/evtchn: read producer index only once drivers/block/xen-blkback/xenbus.c | 2 +- drivers/net/xen-netback/interface.c | 16 ++-- drivers/xen/events/events_2l.c | 20 +++++ drivers/xen/events/events_base.c | 133 ++++++++++++++++++++++------ drivers/xen/evtchn.c | 6 +- drivers/xen/pvcalls-back.c | 4 +- drivers/xen/xen-pciback/xenbus.c | 2 +- drivers/xen/xen-scsiback.c | 2 +- drivers/xen/xenbus/xenbus_probe.c | 66 ++++++++++++++ include/xen/events.h | 7 +- include/xen/xenbus.h | 7 ++ 11 files changed, 217 insertions(+), 48 deletions(-) -- 2.26.2
