The CPUReadMemoryFunc/CPUWriteMemoryFunc typedefs are legacy
remnant from before the conversion to MemoryRegions.
Since they are now only used in tusb6010.c and hcd-musb.c,
move them to "hw/usb/musb.h" and rename them appropriately.

Xen PCI passthrough support may not be available and thus the global
variable "has_igd_gfx_passthru" might be compiled out. Common code
should not access it in that case.
Unfortunately, we can't use CONFIG_XEN_PCI_PASSTHROUGH directly in
xen-common.c so this patch instead move access to the
has_igd_gfx_passthru variable via function and those functions are
also implemented as stubs. The stubs will be used when QEMU is built
without passthrough support.
Now, when one will want to enable igd-passthru via the -machine
property, they will get an error message if QEMU is built without
passthrough support.
Fixes: 46472d8232 ('xen: convert "-machine igd-passthru" to an accelerator property')

Sometimes it would be good to be able to read the pin number along
with the IRQ number allocated. Since we'll dump the IRQ number, no
reason to not dump the pin information. For example, the vfio-pci
device will overwrite the pin with the hardware pin number. It would
be nice to know the pin number of one assigned device from QMP/HMP.

QEMU currently aborts when being started with "-nic model=rocker" or with
"-net nic,model=rocker". This happens because the "rocker" device is not
a normal NIC but a switch, which has different properties. Thus we should
only consider real NIC devices for "-nic" and "-net". These devices can
be identified by the "netdev" property, so check for this property before
adding the device to the list.

Historically, sending all memory regions to vhost-user backends in a
single message imposed a limitation on the number of times memory
could be hot-added to a VM with a vhost-user device. Now that backends
which support the VHOST_USER_PROTOCOL_F_CONFIGURE_SLOTS send memory
regions individually, we no longer need to impose this limitation on
devices which support this feature.
With this change, VMs with a vhost-user device which supports the
VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS can support a configurable
number of memory slots, up to the maximum allowed by the target
platform.
Existing backends which do not support
VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS are unaffected.

With this change, when the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS
protocol feature has been negotiated, Qemu no longer sends the backend
all the memory regions in a single message. Rather, when the memory
tables are set or updated, a series of VHOST_USER_ADD_MEM_REG and
VHOST_USER_REM_MEM_REG messages are sent to transmit the regions to map
and/or unmap instead of sending send all the regions in one fixed size
VHOST_USER_SET_MEM_TABLE message.
The vhost_user struct maintains a shadow state of the VM’s memory
regions. When the memory tables are modified, the
vhost_user_set_mem_table() function compares the new device memory state
to the shadow state and only sends regions which need to be unmapped or
mapped in. The regions which must be unmapped are sent first, followed
by the new regions to be mapped in. After all the messages have been
sent, the shadow state is set to the current virtual device state.
Existing backends which do not support
VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS are unaffected.

This change introduces a new feature to the vhost-user protocol allowing
a backend device to specify the maximum number of ram slots it supports.
At this point, the value returned by the backend will be capped at the
maximum number of ram slots which can be supported by vhost-user, which
is currently set to 8 because of underlying protocol limitations.
The returned value will be stored inside the VhostUserState struct so
that on device reconnect we can verify that the ram slot limitation
has not decreased since the last time the device connected.

The VMD endpoint provides a real PCIe domain to the guest, including
bridges and endpoints. Because the VMD domain is enumerated by the guest
kernel, the guest kernel will assign Guest Physical Addresses to the
downstream endpoint BARs and bridge windows.
When the guest kernel performs MMIO to VMD sub-devices, MMU will
translate from the guest address space to the physical address space.
Because the bridges have been programmed with guest addresses, the
bridges will reject the transaction containing physical addresses.
VMD device 28C0 natively assists passthrough by providing the Host
Physical Address in shadow registers accessible to the guest for bridge
window assignment. The shadow registers are valid if bit 1 is set in VMD
VMLOCK config register 0x70.
In order to support existing VMDs, this quirk provides the shadow
registers in a vendor-specific PCI capability to the vfio-passthrough
device for all VMD device ids which don't natively assist with
passthrough. The Linux VMD driver is updated to check for this new
vendor-specific capability.

This is majorly only for X86 because that's the only one that supports
split irqchip for now.
When the irqchip is split, we face a dilemma that KVM irqfd will be
enabled, however the slow irqchip is still running in the userspace.
It means that the resamplefd in the kernel irqfds won't take any
effect and it will miss to ack INTx interrupts on EOIs.
One example is split irqchip with VFIO INTx, which will break if we
use the VFIO INTx fast path.
This patch can potentially supports the VFIO fast path again for INTx,
that the IRQ delivery will still use the fast path, while we don't
need to trap MMIOs in QEMU for the device to emulate the EIOs (see the
callers of vfio_eoi() hook). However the EOI of the INTx will still
need to be done from the userspace by caching all the resamplefds in
QEMU and kick properly for IOAPIC EOI broadcast.
This is tricky because in this case the userspace ioapic irr &
remote-irr will be bypassed. However such a change will greatly boost
performance for assigned devices using INTx irqs (TCP_RR boosts 46%
after this patch applied).
When the userspace is responsible for the resamplefd kickup, don't
register it on the kvm_irqfd anymore, because on newer kernels (after
commit 654f1f13ea56, 5.2+) the KVM_IRQFD will fail if with both split
irqchip and resamplefd. This will make sure that the fast path will
work for all supported kernels.

VFIO is currently the only one left that is not using the generic

Let VFIO use the common framework too.
Follow up patches will introduce extra features for kvm irqfd, so that
VFIO can easily leverage that after the switch.

vmware-vmx-version is a number returned from CMD_GETVERSION which specifies
to guest VMware Tools the the host VMX version. If the host reports a number
that is different than what the guest VMware Tools expects, it may force
guest to upgrade VMware Tools. (See comment above VERSION_MAGIC and
VmCheck_IsVirtualWorld() function in open-vm-tools open-source code).
For better readability and allow maintaining compatability for guests
which may expect different vmware-vmx-version, make vmware-vmx-version a
VMPort object property. This would allow user to control it's value via
"-global vmport.vmware-vmx-version=X".

vmport_ioport_read() returns the value that should propagate to vCPU EAX
register when guest reads VMPort IOPort (i.e. By x86 IN instruction).
However, because vmport_ioport_read() calls cpu_synchronize_state(), the
returned value gets overridden by the value in QEMU vCPU EAX register.
i.e. cpu->env.regs[R_EAX].
To fix this issue, change vmport_ioport_read() to explicitly override
cpu->env.regs[R_EAX] with the value it wish to propagate to vCPU EAX
register.

Add the VMBus infrastructure -- bus, devices, root bridge, vmbus state
machine, vmbus channel interactions, etc.
VMBus is a collection of technologies. At its lowest layer, it's a message
passing and signaling mechanism, allowing efficient passing of messages to and
from guest VMs. A layer higher, it's a mechanism for defining channels of
communication, where each channel is tagged with a type (which implies a
protocol) and a instance ID. A layer higher than that, it's a bus driver,
serving as the basis of device enumeration within a VM, where a channel can
optionally be exposed as a paravirtual device. When a server-side (paravirtual
back-end) component wishes to offer a channel to a guest VM, it does so by
specifying a channel type, a mode, and an instance ID. VMBus then exposes this
in the guest.
More information about VMBus can be found in the file
vmbuskernelmodeclientlibapi.h in Microsoft's WDK.

When setting the memory tables, qemu uses a memory region's userspace
address to look up the region's MemoryRegion struct. Among other things,
the MemoryRegion contains the region's offset and associated file
descriptor, all of which need to be sent to the backend.
With VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS, this logic will be
needed in multiple places, so before feature support is added it
should be moved to a helper function.
This helper is also used to simplify the vhost_user_can_merge()
function.

A socket write during vhost-user communication may trigger a disconnect
event, calling vhost_user_blk_disconnect() and clearing all the
vhost_dev structures holding data that vhost-user functions expect to
remain valid to roll back initialization correctly. Delay the cleanup to
keep vhost_dev structure valid.
There are two possible states to handle:
1. RUN_STATE_PRELAUNCH: skip bh oneshot call and perform disconnect in
the caller routine.
2. RUN_STATE_RUNNING: delay by using bh
BH changes are based on the similar changes for the vhost-user-net

Add support for free page reporting. The idea is to function very similar
to how the balloon works in that we basically end up madvising the page as
not being used. However we don't really need to bother with any deflate
type logic since the page will be faulted back into the guest when it is
read or written to.
This provides a new way of letting the guest proactively report free
pages to the hypervisor, so the hypervisor can reuse them. In contrast to
inflate/deflate that is triggered via the hypervisor explicitly.

We need to make certain to advertise support for page poison reporting if
we want to actually get data on if the guest will be poisoning pages.
Add a value for reporting the poison value being used if page poisoning is
enabled in the guest. With this we can determine if we will need to skip
free page reporting when it is enabled in the future.
The value currently has no impact on existing balloon interfaces. In the
case of existing balloon interfaces the onus is on the guest driver to
reapply whatever poison is in place.
When we add free page reporting the poison value is used to determine if
we can perform in-place page reporting. The expectation is that a reported
page will already contain the value specified by the poison, and the
reporting of the page should not change that value.

The purpose of vhost_section is to identify RAM regions that need to
be made available to a vhost client. However when running under TCG
all RAM sections have DIRTY_MEMORY_CODE set which leads to problems
down the line.
Re-factor the code so:
- steps are clearer to follow
- reason for rejection is recorded in the trace point
- we allow DIRTY_MEMORY_CODE
We expand the comment to explain that kernel based vhost has specific
support for migration tracking.

The dwc-hsotg (dwc2) USB host depends on a short packet to
indicate the end of an IN transfer. The usb-storage driver
currently doesn't provide this, so fix it.
I have tested this change rather extensively using a PC
emulation with xhci, ehci, and uhci controllers, and have
not observed any regressions.

Add the dwc-hsotg (dwc2) USB host controller emulation code.
Based on hw/usb/hcd-ehci.c and hw/usb/hcd-ohci.c.
Note that to use this with the dwc-otg driver in the Raspbian
kernel, you must pass the option "dwc_otg.fiq_fsm_enable=0" on
the kernel command line.
Emulation of slave mode and of descriptor-DMA mode has not been
implemented yet. These modes are seldom used.
I have used some on-line sources of information while developing
this emulation, including:
http://www.capital-micro.com/PDF/CME-M7_Family_User_Guide_EN.pdf
which has a pretty complete description of the controller starting
on page 370.
https://sourceforge.net/p/wive-ng/wive-ng-mt/ci/master/tree/docs/DataSheets/RT3050_5x_V2.0_081408_0902.pdf
which has a description of the controller registers starting on
page 130.
Thanks to Felippe Mathieu-Daude for providing a cleaner method
of implementing the memory regions for the controller registers.

When inserting the value retrieved (rx) from the spi slave, rx is pushed to
rx_fifo after being cast to uint8_t. rx_fifo is a fifo32, and the rx
register the driver uses is also 32 bit. This zeroes the 24 most
significant bits of rx. This proved problematic with devices that expect to
use the whole 32 bits of the rx register.

Now 2 releases passed, it's time to change the default behavior to

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
boston_mach_init() is wrong that way. The last calls treats an error
as fatal. Do that for the prior ones, too.

If SELinux is setup without 'execmem' permission for qemu, all mmap
with (PROT_WRITE | PROT_EXEC) will fail and print a warning in
SELinux log.
If "nvlink2-mr" memory allocation fails (fist diff), it will cause
guest NUMA nodes to not be correctly configured (V100 memory will
not be visible for guest, nor its NUMA nodes).
Not having 'execmem' permission is intesting for virtual machines to
avoid buffer-overflow based attacks, and it's adopted in distros
like RHEL.
So, removing the PROT_EXEC flag seems the right thing to do.
Browsing some other code that mmaps memory for usage with
memory_region_init_ram_device_ptr, I could notice it's usual to
not have PROT_EXEC (only PROT_READ | PROT_WRITE), so it should be
no problem around this.

On reboot, all memory that was previously added using object_add and
device_add is placed in this DIMM area.
The new SPAPR_LMB_FLAGS_HOTREMOVABLE flag helps Linux to put this memory in
the correct memory zone, so no unmovable allocations are made there,
allowing the object to be easily hot-removed by device_del and
object_del.

Instead of truncating replies, which is problematic, wait until the
client reads more data and frees bytes on the reply ring.
Do that by calling qemu_coroutine_yield(). The corresponding
qemu_coroutine_enter_if_inactive() is called from xen_9pfs_bh upon
receiving the next notification from the client.
We need to be careful to avoid races in case xen_9pfs_bh and the
coroutine are both active at the same time. In xen_9pfs_bh, wait until
either the critical section is over (ring->co == NULL) or until the
coroutine becomes inactive (qemu_coroutine_yield() was called) before
continuing. Then, simply wake up the coroutine if it is inactive.

Locking was introduced in QEMU 2.7 to address the deprecation of
readdir_r(3) in glibc 2.24. It turns out that the frontend code is
the worst place to handle a critical section with a pthread mutex:
the code runs in a coroutine on behalf of the QEMU mainloop and then
yields control, waiting for the fsdev backend to process the request
in a worker thread. If the client resends another readdir request for
the same fid before the previous one finally unlocked the mutex, we're
deadlocked.
This never bit us because the linux client serializes readdir requests
for the same fid, but it is quite easy to demonstrate with a custom
client.
A good solution could be to narrow the critical section in the worker
thread code and to return a copy of the dirent to the frontend, but
this causes quite some changes in both 9p.c and codir.c. So, instead
of that, in order for people to easily backport the fix to older QEMU
versions, let's simply use a CoMutex since all the users for this
sit in coroutines.

The command 0x00 is used by this model since its origin (commit

amusing '/* ??? */' comment, probably meaning 'FIXME'.
switch (cmd) {

This comment survived 12 years because the 0x00 value is indeed

The 'cmd' field is transfered during migration. To keep the

too late to remove a non-specified value from this model
(this would make migration review very complex). It is however
not too late to improve the documentation.
Add few comments to remember this is a special value related
to QEMU, and we won't find information about it on the CFI
spec.

The 'CFI02' NOR flash was introduced in commit 29133e9a0f, with
timing modelled. One year later, the CFI01 model was introduced
(commit 05ee37ebf6) based on the CFI02 model. As noted in the
header, "It does not support timings". 12 years later, we never
had to model the device timings. Time to remove the unused timer,
we can still add it back if required.

Add a definition for the number of GPIO lines controlled by a PL061
instance, and use it instead of the hardcoded magic value 8.

hw_error() calls exit(). This a bit overkill when we can log
the accesses as unimplemented or guest error.
When fuzzing the devices, we don't want the whole process to
exit. Replace some hw_error() calls by qemu_log_mask().
Per the datasheet "Exynos 4412 RISC Microprocessor Rev 1.00"
Chapter 25 "Multi Core Timer (MCT)" figure 1 and table 4,
the default value on the APB bus is 0.
