# LostTickPolicy:
#
# Policy for handling lost ticks in timer devices.
#
# @discard: throw away the missed tick(s) and continue with future injection
# normally. Guest time may be delayed, unless the OS has explicit
# handling of lost ticks
#
# @delay: continue to deliver ticks at the normal rate. Guest time will be
# delayed due to the late tick
#
# @merge: merge the missed tick(s) into one tick and inject. Guest time
# may be delayed, depending on how the OS reacts to the merging
# of ticks
#
# @slew: deliver ticks at a higher rate to catch up with the missed tick. The
# guest time should not be delayed once catchup is complete.

# Since: 2.0

Revert "chardev: Make the name of memory device consistent" This reverts commit 6a85e60cb994bd95d1537aafbff65816f3de4637. Commit 51767e7 "qemu-char: Add new char backend CirMemCharDriver" introduced a memory ring buffer character device driver named "memory". Commit 3949e59 "qemu-char: Saner naming of memchar stuff & doc fixes" changed the driver name to "ringbuf", along with a whole bunch of other names, with the following rationale: Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. This is what we released in 1.4.0. Unfortunately, the rename missed a critical instance of "memory": the actual driver name. Thus, the new device could be used only by an entirely undocumented name. The documented name did not work. Bummer. Commit 6a85e60 fixes this by changing the documentation to match the code. It also changes some, but not all related occurences of "ringbuf" to "memory". Left alone are identifiers in C code, HMP and QMP commands. The latter are external interface, so they can't be changed. The result is an inconsistent mess. Moreover, "memory" is a rotten name. The device's distinctive property is that it's a ring buffer, not that's in memory. User's don't care whether it's in RAM, flash, or carved into chocolate tablets by Oompa Loompas. Revert the commit. Next commit will fix just the bug.

Revert "chardev: Make the name of memory device consistent" This reverts commit 6a85e60cb994bd95d1537aafbff65816f3de4637. Commit 51767e7 "qemu-char: Add new char backend CirMemCharDriver" introduced a memory ring buffer character device driver named "memory". Commit 3949e59 "qemu-char: Saner naming of memchar stuff & doc fixes" changed the driver name to "ringbuf", along with a whole bunch of other names, with the following rationale: Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. This is what we released in 1.4.0. Unfortunately, the rename missed a critical instance of "memory": the actual driver name. Thus, the new device could be used only by an entirely undocumented name. The documented name did not work. Bummer. Commit 6a85e60 fixes this by changing the documentation to match the code. It also changes some, but not all related occurences of "ringbuf" to "memory". Left alone are identifiers in C code, HMP and QMP commands. The latter are external interface, so they can't be changed. The result is an inconsistent mess. Moreover, "memory" is a rotten name. The device's distinctive property is that it's a ring buffer, not that's in memory. User's don't care whether it's in RAM, flash, or carved into chocolate tablets by Oompa Loompas. Revert the commit. Next commit will fix just the bug.

net: add support of mac-programming over macvtap in QEMU side Currently macvtap based macvlan device is working in promiscuous mode, we want to implement mac-programming over macvtap through Libvirt for better performance. Design: QEMU notifies Libvirt when rx-filter config is changed in guest, then Libvirt query the rx-filter information by a monitor command, and sync the change to macvtap device. Related rx-filter config of the nic contains main mac, rx-mode items and vlan table. This patch adds a QMP event to notify management of rx-filter change, and adds a monitor command for management to query rx-filter information. Test: If we repeatedly add/remove vlan, and change macaddr of vlan interfaces in guest by a loop script. Result: The events will flood the QMP client(management), management takes too much resource to process the events. Event_throttle API (set rate to 1 ms) can avoid the events to flood QMP client, but it could cause an unexpected delay (~1ms), guests guests normally expect rx-filter updates immediately. So we use a flag for each nic to avoid events flooding, the event is emitted once until the query command is executed. The flag implementation could not introduce unexpected delay. There maybe exist an uncontrollable delay if we let Libvirt do the real change, guests normally expect rx-filter updates immediately. But it's another separate issue, we can investigate it when the work in Libvirt side is done. Michael S. Tsirkin: tweaked to enable events on start Michael S.
