0a96ca2437 hw/scsi: cleanups before VPD BL emulation
To add support for the emulation of Block Limits VPD page
for passthrough devices, a few adjustments in the current code
base is required to avoid repetition and improve clarity.

In scsi-generic.c, detach the Inquiry handling from
scsi_read_complete and put it into a new function called
scsi_handle_inquiry_reply. This change aims to avoid
cluttering of scsi_read_complete when we more logic in the
Inquiry response handling is added in the next patches,
centralizing the changes in the new function.

In scsi-disk.c, take the build of all emulated VPD pages
from scsi_disk_emulate_inquiry and make it available to
other files into a non-static function called
scsi_disk_emulate_vpd_page. Making it public will allow
the future VPD BL emulation code for passthrough devices
to use it from scsi-generic.c, avoiding copy/pasting this
code solely for that purpose. It also has the advantage of
providing emulation of all VPD pages in case we need to
emulate other pages in other scenarios. As a bonus,
scsi_disk_emulate_inquiry got tidier.

cce5405e0e ioapic: support "info irq"
This include both userspace and in-kernel ioapic.  Note that the numbers
can be inaccurate for kvm-ioapic.  One reason is the same with
kvm-i8259, that when irqfd is used, irqs can be delivered all inside
kernel without our notice.  Meanwhile, kvm-ioapic is specially treated
when irq numbers <ISA_NUM_IRQS, those irqs will be delivered in kernel
too via kvm-i8259 (please refer to kvm_pc_gsi_handler).

f0b7bca64d pc-dimm: get_memory_region() will not fail after realize
Let's try to reduce error handling a bit. In the plug/unplug case, the
device was realized and therefore we can assume that getting access to
the memory region will not fail.

For get_vmstate_memory_region() this is already handled that way.
Document both cases.

Importantly, get_vmstate_memory_region() should also fail with a proper
error if called before the device is realized. For a PCDIMM, both functions
are to return the same thing, so share the implementation.

All current users are called after the device has been realized, so we

Only retry on serial_xmit if qemu_chr_fe_write returns 0, as this is the

Retrying with any other scenario, in addition to being a waste of CPU
cycles, can compromise the Guest stability if by the vCPU issuing the
write and the main loop thread are, by chance or explicit pinning,
running on the same pCPU.

4f91740698 hw/pci-host/xilinx-pcie: don't make "io" region be RAM
Currently we use memory_region_init_rom_nomigrate() to create
the "io" memory region to pass to pci_register_root_bus().
This is a dummy region, because this PCI controller doesn't
support accesses to PCI IO space.

There is no reason for the dummy region to be a RAM region;
it is only used as a place where PCI BARs can be mapped,
and if you could get a PCI card to do a bus master access
to the IO space it should not get acts-like-RAM behaviour.
Use a simple container memory region instead. (We do have
one PCI card model which can do bus master accesses to IO
space -- the LSI53C895A SCSI adaptor.)

This avoids the oddity of having a memory region which is
RAM but where the RAM is not migrated.

Note that the size of the region we use here has no
effect on behaviour.

9b945a9ee3 aspeed/timer: use the APB frequency from the SCU
The timer controller can be driven by either an external 1MHz clock or
by the APB clock. Today, the model makes the assumption that the APB
frequency is always set to 24MHz but this is incorrect.

The AST2400 SoC on the palmetto machines uses a 48MHz input clock
source and the APB can be set to 48MHz. The consequence is a general
system slowdown. The QEMU machines using the AST2500 SoC do not seem
impacted today because the APB frequency is still set to 24MHz.

We fix the timer frequency for all SoCs by linking the Timer model to
the SCU model. The APB frequency driving the timers is now the one
configured for the SoC.

fda9aaa60e aspeed/scu: introduce clock frequencies
All Aspeed SoC clocks are driven by an input source clock which can
have different frequencies : 24MHz or 25MHz, and also, on the Aspeed
AST2400 SoC, 48MHz. The H-PLL (CPU) clock is defined from a
calculation using parameters in the H-PLL Parameter register or from a
predefined set of frequencies if the setting is strapped by hardware
(Aspeed AST2400 SoC). The other clocks of the SoC are then defined
from the H-PLL using dividers.

We introduce first the APB clock because it should be used to drive
the Aspeed timer model.

832e4222c8 hw/arm/smmuv3: Add notifications on invalidation
On TLB invalidation commands, let's call registered
IOMMU notifiers. Those can only be UNMAP notifiers.
SMMUv3 does not support notification on MAP (VFIO).

This patch allows vhost use case where IOTLB API is notified
on each guest IOTLB invalidation.

cc27ed81cf hw/arm/smmuv3: IOTLB emulation
We emulate a TLB cache of size SMMU_IOTLB_MAX_SIZE=256.
It is implemented as a hash table whose key is a combination
of the 16b asid and 48b IOVA (Jenkins hash).

Entries are invalidated on TLB invalidation commands, either
globally, or per asid, or per asid/iova.

32cfd7f39e hw/arm/smmuv3: Cache/invalidate config data
Let's cache config data to avoid fetching and parsing STE/CD
structures on each translation. We invalidate them on data structure
invalidation commands.

We put in place a per-smmu mutex to protect the config cache. This
will be useful too to protect the IOTLB cache. The caches can be
accessed without BQL, ie. in IO dataplane. The same kind of mutex was
put in place in the intel viommu.

9122bea986 hw/arm/smmuv3: Fix translate error handling
In case the STE's config is "Bypass" we currently don't set the
IOMMUTLBEntry perm flags and the access does not succeed. Also
if the config is 0b0xx (Aborted/Reserved), decode_ste and
smmuv3_decode_config currently returns -EINVAL and we don't enter
the expected code path: we record an event whereas we should not.

This patch fixes those bugs and simplifies the error handling.
decode_ste and smmuv3_decode_config now return 0 if aborted or
bypassed config was found. Only bad config info produces negative
error values. In smmuv3_translate we more clearly differentiate
errors, bypass/smmu disabled, aborted and success cases. Also
trace points are differentiated.
