Emit a QMP event on receiving a PVPANIC_SHUTDOWN event. Even though a typical
SHUTDOWN event will be sent, it will be indistinguishable from a shutdown
originating from other cases (e.g. KVM exit due to KVM_SYSTEM_EVENT_SHUTDOWN)
that also issue the guest-shutdown cause.
The missing functionality has been implemented now.
This reverts commit e739d1935c461d0668057e9dbba9d06f728d29ec.

The different components of pvpanic duplicate the list of supported
events. Move it to the shared header file to minimize changes when new
events are added.

Shutdown requests are normally hardware dependent.
By extending pvpanic to also handle shutdown requests, guests can
submit such requests with an easily implementable and cross-platform
mechanism.

hw/misc
and 2 are general cleanups, that seems useful even without this
proposal being implemented.
I'll send the corresponding Linux patch to LKML.

Thomas Weißschuh (3):
hw/misc/pvpanic
Hi everybody,
the mechanism for a (Linux) guest to signal a regular shutdown event to
QEMU seems fairly architecture specific and dependent on kernel
configuration.
The existing pvpanic protocol [0] could be extended fairly easily to
also cover these events.
Any thoughts?
Thanks,
Thomas

Passing the struct around explicitly makes the control-flow more

The kernel does not require PROT_READ for addresses passed to mincore.
v1: https://lore.kernel.org/qemu-devel/20230416195103.607948-1-tho...@t-8ch.de/
v1 -> v2:
* Introduce symbolic flag VERIFY_NONE instead of hardcoding "0"
Thomas Weißschuh (2):
linux-user: Add new flag VERIFY
This can be used to validate that an address range is mapped but without
being readable or writable.
It will be used by an updated implementation of mincore().

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.
Take advantage of this to constify the structure definition to prevent
modification at runtime.
