1e7cf8c323 migration/postcopy: unsentmap is not necessary for postcopy
Commit f3f491fcd6 ('Postcopy: Maintain unsentmap') introduced
unsentmap to track not yet sent pages.

This is not necessary since:

    * unsentmap is a sub-set of bmap before postcopy start
    * unsentmap is the summation of bmap and unsentmap after canonicalizing

This patch just removes it.

3809f7583b xen: perform XenDevice clean-up in XenBus watch handler
Cleaning up offline XenDevice objects directly in
xen_device_backend_changed() is dangerous as xen_device_unrealize() will
modify the watch list that is being walked. Even the QLIST_FOREACH_SAFE()
used in notifier_list_notify() is insufficient as *two* notifiers (for
the frontend and backend watches) are removed, thus potentially rendering
the 'next' pointer unsafe.

The solution is to use the XenBus backend_watch handler to do the clean-up
instead, as it is invoked whilst walking a separate watch list.

This patch therefore adds a new 'inactive_devices' list to XenBus, to which
offline devices are added by xen_device_backend_changed(). The XenBus
backend_watch registration is also changed to not only invoke
xen_bus_enumerate() but also a new xen_bus_cleanup() function, which will
walk 'inactive_devices' and perform the necessary actions.
For safety an extra 'online' check is also added to xen_bus_type_enumerate()
to make sure that no attempt is made to create a new XenDevice object for a
backend that is offline.

NOTE: This patch also includes some cosmetic changes:
      - substitute the local variable name 'backend_state'
        in xen_bus_type_enumerate() with 'state', since there
        is no ambiguity with any other state in that context.
      - change xen_device_state_is_active() to
        xen_device_frontend_is_active() (and pass a XenDevice directly)
        since the state tests contained therein only apply to a frontend.
      - use 'state' rather then 'xendev->backend_state' in
        xen_device_backend_changed() to shorten the code.

d198b711f9 xen: introduce separate XenWatchList for XenDevice objects
This patch uses the XenWatchList abstraction to add a separate watch list
for each device. This is more scalable than walking a single notifier
list for all watches and is also necessary to implement a bug-fix in a
subsequent patch.

374752a26b xen / notify: introduce a new XenWatchList abstraction
Xenstore watch call-backs are already abstracted away from XenBus using
the XenWatch data structure but the associated NotifierList manipulation
and file handle registration is still open coded in various xen_bus_...()
functions.
This patch creates a new XenWatchList data structure to allow these
interactions to be abstracted away from XenBus as well. This is in
preparation for a subsequent patch which will introduce separate watch lists
for XenBus and XenDevice objects.

NOTE: This patch also introduces a new notifier_list_empty() helper function
      for the purposes of adding an assertion that a XenWatchList is not
      freed whilst its associated NotifierList is still occupied.

ebe15582ca pc: Add an SMB0 ACPI device to q35
This is so I2C devices can be found in the ACPI namespace.  Currently
that's only IPMI, but devices can be easily added now.

Adding the devices required some PCI information, and the bus itself
to be added to the PCMachineState structure.

Note that this only works on Q35, the ACPI for PIIX4 is not capable
of handling an SMBus device.

7cc0cdcd6a RISC-V Patches for the 4.2 Soft Freeze, Part 1, v3
This contains quite a few patches that I'd like to target for 4.2.
 They're mostly emulation fixes for the sifive_u board, which now much
 more closely matches the hardware and can therefor run the same fireware
 as what gets loaded onto the board.  Additional user-visible
 improvements include:
 
 * support for loading initrd files from the command line into Linux, via
   /chosen/linux,initrd-{start,end} device tree nodes.
 * The conversion of LOG_TRACE to trace events.
 * The addition of clock DT nodes for our uart and ethernet.
 
 This also includes some preliminary work for the H extension patches,
 but does not include the H extension patches as I haven't had time to
 review them yet.
 
 This passes my OE boot test on 32-bit and 64-bit virt machines, as well
 as a 64-bit upstream Linux boot on the sifive_u machine.  It has been
 fixed to actually pass "make check" this time.
 
 Changes since v2 (never made it to the list):
 
 * Sets the sifive_u machine default core count to 2 instead of 5.
 
 Changes since v1 <20190910190513.21160-1-palmer@sifive.com>:

31e404151b cutils: Move size_to_str() from "qemu-common.h" to "qemu/cutils.h"
"qemu/cutils.h" contains various qemu_strtosz_*() functions
useful to convert strings to size. It seems natural to have
the opposite usage (from size to string) there too.

The function definition is already in util/cutils.c.

riscv: sifive_u: Remove handcrafted clock nodes for UART and ethernet
In the past we did not have a model for PRCI, hence two handcrafted
clock nodes ("/soc/ethclk" and "/soc/uartclk") were created for the
purpose of supplying hard-coded clock frequencies. But now since we
have added the PRCI support in QEMU, we don't need them any more.

riscv: sifive_u: Fix broken GEM support
At present the GEM support in sifive_u machine is seriously broken.
The GEM block register base was set to a weird number (0x100900FC),
which for no way could work with the cadence_gem model in QEMU.

Not like other GEM variants, the FU540-specific GEM has a management
block to control 10/100/1000Mbps link speed changes, that is mapped
to 0x100a0000. We can simply map it into MMIO space without special
handling using create_unimplemented_device().

Update the GEM node compatible string to use the official name used
by the upstream Linux kernel, and add the management block reg base
& size to the <reg> property encoding.

Tested with upstream U-Boot and Linux kernel MACB drivers.

7a3df11c2a memory: inline and optimize devend_memop
devend_memop can rely on the fact that the result is always either
0 or MO_BSWAP, corresponding respectively to host endianness and
the opposite.  Native (target) endianness in turn can be either
the host endianness, in which case MO_BSWAP is only returned for
host-opposite endianness, or the opposite, in which case 0 is only
returned for host endianness.

With this in mind, devend_memop can be compiled as a setcond+shift
for every target.  Do this and, while at it, move it to
include/exec/memory.h since !NEED_CPU_H files do not (and should not)
need it.

72d41eb4b8 memory: fetch pmem size in get_file_size()
Neither stat(2) nor lseek(2) report the size of Linux devdax pmem
character device nodes.  Commit 314aec4a6e
("hostmem-file: reject invalid pmem file sizes") added code to
hostmem-file.c to fetch the size from sysfs and compare against the
user-provided size=NUM parameter:

  if (backend->size > size) {
      error_setg(errp, "size property %" PRIu64 " is larger than "
                 "pmem file \"%s\" size %" PRIu64, backend->size,
                 fb->mem_path, size);
      return;
  }

It turns out that exec.c:qemu_ram_alloc_from_fd() already has an
equivalent size check but it skips devdax pmem character devices because
lseek(2) returns 0:

  if (file_size > 0 && file_size < size) {
      error_setg(errp, "backing store %s size 0x%" PRIx64
                 " does not match 'size' option 0x" RAM_ADDR_FMT,
                 mem_path, file_size, size);
      return NULL;
  }

This patch moves the devdax pmem file size code into get_file_size() so
that we check the memory size in a single place:
qemu_ram_alloc_from_fd().  This simplifies the code and makes it more
general.

This also fixes the problem that hostmem-file only checks the devdax
pmem file size when the pmem=on parameter is given.  An unchecked
size=NUM parameter can lead to SIGBUS in QEMU so we must always fetch
the file size for Linux devdax pmem character device nodes.

a8f07376c9 aspeed/scu: Introduce a aspeed_scu_get_apb_freq() routine
The APB frequency can be calculated directly when needed from the
HPLL_PARAM and CLK_SEL register values. This removes useless state in
the model.

5258c2a69c aspeed/smc: Inject errors in DMA checksum
Emulate read errors in the DMA Checksum Register for high frequencies
and optimistic settings of the Read Timing Compensation Register. This
will help in tuning the SPI timing calibration algorithm. Errors are
only injected when the property "inject_failure" is set to true as
suggested by Philippe.

The values below are those to expect from the first flash device of
the FMC controller of a palmetto-bmc machine.

c4e1f0b483 aspeed/smc: Add support for DMAs
The FMC controller on the Aspeed SoCs support DMA to access the flash
modules. It can operate in a normal mode, to copy to or from the flash
module mapping window, or in a checksum calculation mode, to evaluate
the best clock settings for reads.

The model introduces two custom address spaces for DMAs: one for the
AHB window of the FMC flash devices and one for the DRAM. The latter
is populated using a "dram" link set from the machine with the RAM
container region.
