hw/intc/arm_gicv3_its: Implement state save/restore
We need to handle both registers and ITS tables. While
register handling is standard, ITS table handling is more
challenging since the kernel API is devised so that the
tables are flushed into guest RAM and not in vmstate buffers.
Flushing the ITS tables on device pre_save() is too late
since the guest RAM is already saved at this point.
Table flushing needs to happen when we are sure the vcpus
are stopped and before the last dirty page saving. The
right point is RUN_STATE_FINISH_MIGRATE but sometimes the
VM gets stopped before migration launch so let's simply
flush the tables each time the VM gets stopped.
For regular ITS registers we just can use vmstate pre_save()
and post_load() callbacks.

kvm-all: Pass an error object to kvm_device_access
In some circumstances, we don't want to abort if the
kvm_device_access fails. This will be the case during ITS
migration, in case the ITS table save/restore fails because
the guest did not program the vITS correctly. So let's pass an
error object to the function and return the ioctl value. New
callers will be able to make a decision upon this returned
value.
Existing callers pass &error_abort which will cause the
function to abort on failure.

xics: setup cpu at realize time
Until recently, spapr used to allocate ICPState objects for the lifetime
of the machine. They would only be associated to vCPUs in xics_cpu_setup()
when plugging a CPU core.
Now that ICPState objects have the same lifecycle as vCPUs, it is
possible to associate them during realization.
This patch hence open-codes xics_cpu_setup() in icp_realize(). The vCPU
is passed as a property. Note that vCPU now needs to be realized first
for the IRQs to be allocated. It also needs to resetted before ICPState
realization in order to synchronize with KVM.
Since ICPState objects are freed when unrealized, xics_cpu_destroy() isn't
needed anymore and can be safely dropped.

Taking into account that qemu_set_irq() returns immediatly if its first

This patch introduces a reset() handler, so that the common logic can
be implemented in icp_reset() only.
While there we can also drop icp_kvm_realize() and icp_kvm_unrealize(). This
causes icp-kvm to be realized in icp_realize(), which sets icp->xics, but
it has no impact.

target-ppc: Fix openpic timer read register offset
openpic_tmr_read() is incorrectly computing register offset of the
TCCR, TBCR, TVPR, and TDR registers when accessing the open pic timer
registers. Specifically the offset of timer registers for
openpic_tmr_read() is not accounting for the timer frequency reporting
register (TFFR) which is the first register in the "tmr" memory
region.
openpic_tmr_write() *is* correctly computing the offset by adding
0x10f0 to the address prior to computing the register index. This
patch instead subtracts 0x10 in both the read and write routines and
eliminates some other gratuitous differences between the functions.

The M series MPU is almost the same as the already implemented R

This implementation has the same restriction as the R profile MPU
that it doesn't permit regions to be sized down smaller than 1K.
We also do not yet implement support for MPU_CTRL.HFNMIENA; this
bit should if zero disable use of the MPU when running HardFault,

When we calculate the mask to use to get the group priority from

the group priority is in bits [7:1], whereas for BPR0 and S BPR1
this is indicated by a 0 BPR value.

we're using the NS BPR value, for both hardware and virtual
interrupts, as the GICv3 pseudocode does, and fix the comments
accordingly.

xics_kvm: cache already enabled vCPU ids
Since commit a45863bda90d ("xics_kvm: Don't enable KVM_CAP_IRQ_XICS if

unplugged ealier, thanks to a boolean flag in ICPState that we set when
enabling KVM_CAP_IRQ_XICS.
This could work because the lifecycle of all ICPState objects was the
same as the machine. Commit 5bc8d26de20c ("spapr: allocate the ICPState
object from under sPAPRCPUCore") broke this assumption and now we always
pass a freshly allocated ICPState object (ie, with the flag unset) to
icp_kvm_cpu_setup().
This cause re-hotplug to fail with:
Unable to connect CPU8 to kernel XICS: Device or resource busy
Let's fix this by caching all the vCPU ids for which KVM_CAP_IRQ_XICS was
enabled. This also drops the now useless boolean flag from ICPState.

sysbus: Set user_creatable=false by default on TYPE_SYS_BUS_DEVICE
commit 33cd52b5d7b9adfd009e95f07e6c64dd88ae2a31 unset
cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all
sysbus devices appear on "-device help" and lack the "no-user"
flag in "info qdm".
To fix this, we can set user_creatable=false by default on
TYPE_SYS_BUS_DEVICE, but this requires setting
user_creatable=true explicitly on the sysbus devices that
actually work with -device.
Fortunately today we have just a few has_dynamic_sysbus=1
machines: virt, pc-q35-*, ppce500, and spapr.
virt, ppce500, and spapr have extra checks to ensure just a few
device types can be instantiated:
* virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE.
* ppce500 supports only TYPE_ETSEC_COMMON.
* spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE.
This patch sets user_creatable=true explicitly on those 4 device
classes.
Now, the more complex cases:
pc-q35-*: q35 has no sysbus device whitelist yet (which is a
separate bug). We are in the process of fixing it and building a
sysbus whitelist on q35, but in the meantime we can fix the
"-device help" and "info qdm" bugs mentioned above. Also, despite
not being strictly necessary for fixing the q35 bug, reducing the
list of user_creatable=true devices will help us be more
confident when building the q35 whitelist.
xen: We also have a hack at xen_set_dynamic_sysbus(), that sets
has_dynamic_sysbus=true at runtime when using the Xen
accelerator. This hack is only used to allow xen-backend devices
to be dynamically plugged/unplugged.
This means today we can use -device with the following 22 device
types, that are the ones compiled into the qemu-system-x86_64 and
qemu-system-i386 binaries:
* allwinner-ahci
* amd-iommu
* cfi.pflash01
* esp
* fw_cfg_io
* fw_cfg_mem
* generic-sdhci
* hpet
* intel-iommu
* ioapic
* isabus-bridge
* kvmclock
* kvm-ioapic
* kvmvapic
* SUNW,fdtwo
* sysbus-ahci
* sysbus-fdc
* sysbus-ohci
* unimplemented-device
* virtio-mmio
* xen-backend
* xen-sysdev
This patch adds user_creatable=true explicitly to those devices,
temporarily, just to keep 100% compatibility with existing
behavior of q35. Subsequent patches will remove
user_creatable=true from the devices that are really not meant to
user-creatable on any machine, and remove the FIXME comment from
the ones that are really supposed to be user-creatable. This is
being done in separate patches because we still don't have an
obvious list of devices that will be whitelisted by q35, and I
would like to get each device reviewed individually.

qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631d94160288392721a5f9c39e50fb2bc to replace no_user.
qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631d94160288392721a5f9c39e50fb2bc to replace no_user. It was
supposed to be a temporary measure.
When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.
Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.
Except for code comments, changes were generated using the
following Coccinelle patch:
