This is the patch I sent out yesterday for Linux to clean up the guest ID mess.
For FreeBSD, you can use the following constant:
HV_FREEBSD_VENDOR_ID0x8200
and use the function to generate the ID appropriately. Larry, I will forward

The function has a goto from the very end to the very beginning, and there
are a lot of ifs in between. It seems possible that there is too much
information, and it gets too slow. I will look further.

Hi Devendra,
Thanks for cleaning up the driver. If I understand the code
correctly, the original author wanted to initialize wm_event once and
reuse it for multiple devices, and thus reference counted it with
ref_cnt.

This patch adds logic to parse lis3 properties from a device tree node
and store them in a freshly allocated lis3lv02d_platform_data.
Note that the actual match tables are left out here. This part should
happen in the drivers that bind to the individual busses (SPI/I2C/PCI).

When using the commands below to write some data to a virtio-scsi LUN of the
QEMU guest(32-bit) with 1G physical memory(qemu -m 1024), the qemu will crash.
# sudo mkfs.ext4 /dev/sdb (/dev/sdb is the virtio-scsi LUN.)

Let the driver compile everywhere while

If probed from a device tree, this driver now passes the node
information to the generic part, so the runtime information can be
derived.

This patch adds logic to parse lis3 properties from a device tree node
and store them in a freshly allocated lis3lv02d_platform_data.
Note that the actual match tables are left out here. This part should
happen in the drivers that bind to the individual busses (SPI/I2C/PCI).

The MSI specification has several constraints in comparison with MSI-X,
most notable of them is the inability to configure MSIs independently.
As a result, it is impossible to dispatch interrupts from different
queues to different CPUs. This is largely devalues the support of
multiple MSIs in SMP

During CPU hotplug, we want to create the following effect:
* During CPU online, the CPU incrementally grows the number of services
it offers.
* During CPU offline, the services are incrementally retired, in the
reverse order of their growth during CPU online.
To achieve the above, invoke
While dealing with reverse invocation of callbacks during CPU offline, we
get an opportunity to revisit some of the reasons behind the existing callback
invocation orders and how they would fit into the new reverse invocation model
(which poses its own constraints and challenges).
It is
Some of the CPU hotplug callbacks of the scheduler and cpuset infrastructure are
intertwined in an interesting way. The scheduler's sched_cpu_[in]active()
callbacks and cpuset's cpuset_cpu_[in]active() callbacks have the following
documented dependency:
The sched_cpu_active() callback must be the
In certain scenarios, it is useful to be able to invoke notifiers in the
reverse order. One such example is CPU hotplug, where we would like to
invoke the notifiers in one order during CPU online and in the reverse
order during CPU offline. So add support for reverse invocation of
notifier chains.
In order to support invoking the notifiers in the reverse order, we need to
be able to traverse the callback chain in both directions. So convert the
notifier list into a circular doubly linked list.

Hi,
This patchset implements the approach of invoking the CPU hotplug callbacks
(notifiers) in one order during CPU online and in the reverse order during CPU
offline. The rationale behind this is that services for a CPU are started in a
particular order (perhaps, with implicit dependencies
Provide a helper to traverse an RCU-protected doubly linked list in the reverse
order. Also add a corresponding helper to delete entries from the linked list,
which takes care to see that we don't poison either of the pointers (->prev
and ->next), since it is legal to run an rcu list-traversal
