c6941b3b9b net: Move the code to collect available NIC models to a separate function
The code that collects the available NIC models is not really specific
to PCI anymore and will be required in the next patch, too, so let's
move this into a new separate function in net.c instead.

24beea4efe migration: Rename res_{postcopy,precopy}_only
Once that res_compatible is removed, they don't make sense anymore.
We remove the _only preffix.  And to make things clearer we rename
them to must_precopy and can_postcopy.

1f433e84c3 virtio-blk: add missing AioContext lock
virtio_blk_update_config() calls blk_get_geometry and blk_getlength,
and both functions eventually end up calling bdrv_poll_co when not
running in a coroutine:
- blk_getlength is a co_wrapper_mixed function
- blk_get_geometry calls bdrv_get_geometry -> bdrv_nb_sectors, a
  co_wrapper_mixed function too

Since we are not running in a coroutine, we need to take s->blk
AioContext lock, otherwise bdrv_poll_co will inevitably call
AIO_WAIT_WHILE and therefore try to un unlock() an AioContext lock
that was never acquired.

RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=2167838

Steps to reproduce the issue: simply boot a VM with
-object '{"qom-type":"iothread","id":"iothread1"}' \
-blockdev '{"driver":"file","filename":"$QCOW2","aio":"native","node-name":"libvirt-1-storage","cache":{"direct":true,"no-flush":false},"auto-read-only":true,"discard":"unmap"}' \
-blockdev '{"node-name":"libvirt-1-format","read-only":false,"cache":{"direct":true,"no-flush":false},"driver":"qcow2","file":"libvirt-1-storage"}' \
-device virtio-blk-pci,iothread=iothread1,drive=libvirt-1-format,id=virtio-disk0,bootindex=1,write-cache=on

and observe that it will fail not manage to boot with "qemu_mutex_unlock_impl: Operation not permitted"

626fb3c6a8 hw/input: Clean up includes
This commit was created with scripts/clean-includes.

All .c should include qemu/osdep.h first.  The script performs three
related cleanups:

* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c  already includes
  it.  Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
  Drop these, too.

6ba3dc2516 hw/arm/aspeed_ast10x0: Map the secure SRAM
Some SRAM appears to be used by the Secure Boot unit and
crypto accelerators. Name it 'secure sram'.

Note, the SRAM base address was already present but unused
(the 'SBC' index is used for the MMIO peripheral).

Interestingly using CFLAGS=-Winitializer-overrides reports:

  ../hw/arm/aspeed_ast10x0.c:32:30: warning: initializer overrides prior initialization of this subobject [-Winitializer-overrides]
    [ASPEED_DEV_SBC]       = 0x7E6F2000,

4ef247661e hw/watchdog/wdt_aspeed: Extend MMIO range to cover more registers
When booting the Zephyr demo in [1] we get:

  aspeed.io: unimplemented device write (size 4, offset 0x185128, value 0x030f1ff1) <--
  aspeed.io: unimplemented device write (size 4, offset 0x18512c, value 0x03fffff1)

This corresponds to this Zephyr code [2]:

  static int aspeed_wdt_init(const struct device *dev)
  {
    const struct aspeed_wdt_config *config = dev->config;
    struct aspeed_wdt_data *const data = dev->data;
    uint32_t reg_val;

    /* disable WDT by default */
    reg_val = sys_read32(config->ctrl_base + WDT_CTRL_REG);
    reg_val &= ~WDT_CTRL_ENABLE;
    sys_write32(reg_val, config->ctrl_base + WDT_CTRL_REG);

    sys_write32(data->rst_mask1,
                config->ctrl_base + WDT_SW_RESET_MASK1_REG);   <------
    sys_write32(data->rst_mask2,
                config->ctrl_base + WDT_SW_RESET_MASK2_REG);

    return 0;
  }

The register definitions are [3]:

  #define WDT_RELOAD_VAL_REG          0x0004
  #define WDT_RESTART_REG             0x0008
  #define WDT_CTRL_REG                0x000C
  #define WDT_TIMEOUT_STATUS_REG      0x0010
  #define WDT_TIMEOUT_STATUS_CLR_REG  0x0014
  #define WDT_RESET_MASK1_REG         0x001C
  #define WDT_RESET_MASK2_REG         0x0020
  #define WDT_SW_RESET_MASK1_REG      0x0028   <------
  #define WDT_SW_RESET_MASK2_REG      0x002C
  #define WDT_SW_RESET_CTRL_REG       0x0024

Currently QEMU only cover a MMIO region of size 0x20:

  #define ASPEED_WDT_REGS_MAX        (0x20 / 4)

Change to map the whole 'iosize' which might be bigger, covering
the other registers. The MemoryRegionOps read/write handlers will
report the accesses as out-of-bounds guest-errors, but the next
commit will report them as unimplemented.

6fdb438187 hw/watchdog/wdt_aspeed: Rename MMIO region size as 'iosize'
Avoid confusing two different things:
- the WDT I/O region size ('iosize')
- at which offset the SoC map the WDT ('offset')
While it is often the same, we can map smaller region sizes
at larger offsets.

Here we are interested in the I/O region size, so rename as
'iosize'.

4f2c6448c3 hw/nvram/eeprom_at24c: Make reset behavior more like hardware
EEPROM's are a form of non-volatile memory. After power-cycling an EEPROM,
I would expect the I2C state machine to be reset to default values, but I
wouldn't really expect the memory to change at all.

The current implementation of the at24c EEPROM resets its internal memory on
reset. This matches the specification in docs/devel/reset.rst:

  Cold reset is supported by every resettable object. In QEMU, it means we reset
  to the initial state corresponding to the start of QEMU; this might differ
  from what is a real hardware cold reset. It differs from other resets (like
  warm or bus resets) which may keep certain parts untouched.

But differs from my intuition. For example, if someone writes some information
to an EEPROM, then AC power cycles their board, they would expect the EEPROM to
retain that information. It's very useful to be able to test things like this
in QEMU as well, to verify software instrumentation like determining the cause
of a reboot.

036e98e5c2 hw/net: Fix read of uninitialized memory in ftgmac100
With the `size += 4` before the call to `crc32`, the CRC calculation
would overrun the buffer. Size is used in the while loop starting on
line 1009 to determine how much data to write back, with the last
four bytes coming from `crc_ptr`, so do need to increase it, but should
do this after the computation.

I'm unsure why this use of uninitialized memory in the CRC doesn't
result in CRC errors, but it seems clear to me that it should not be
included in the calculation.

479365979b aspeed: Add Supermicro X11 SPI machine type
supermicrox11-bmc is configured with ast2400-a1 SoC. This does not match
the Supermicro documentation for X11 BMCs, and it does not match the
devicetree file in the Linux kernel.

As it turns out, some Supermicro X11 motherboards use AST2400 SoCs,
while others use AST2500.

Introduce new machine type supermicrox11-spi-bmc with AST2500 SoC
to match the devicetree description in the Linux kernel. Hardware
configuration details for this machine type are guesswork and taken
from defaults as well as from the Linux kernel devicetree file.

The new machine type was tested with aspeed-bmc-supermicro-x11spi.dts
from the Linux kernel and with Linux versions 6.0.3 and 6.1-rc2.
Linux booted successfully from initrd and from both SPI interfaces.
Ethernet interfaces were confirmed to be operational.

4b402886ac hw/riscv: change riscv_compute_fdt_addr() semantics
As it is now, riscv_compute_fdt_addr() is receiving a dram_base, a
mem_size (which is defaulted to MachineState::ram_size in all boards)
and the FDT pointer. And it makes a very important assumption: the DRAM
interval dram_base + mem_size is contiguous. This is indeed the case for
most boards that use a FDT.

The Icicle Kit board works with 2 distinct RAM banks that are separated
by a gap. We have a lower bank with 1GiB size, a gap follows, then at
64GiB the high memory starts. MachineClass::default_ram_size for this
board is set to 1.5Gb, and machine_init() is enforcing it as minimal RAM
size, meaning that there we'll always have at least 512 MiB in the Hi
RAM area.

Using riscv_compute_fdt_addr() in this board is weird because not only
the board has sparse RAM, and it's calling it using the base address of
the Lo RAM area, but it's also using a mem_size that we have guarantees
that it will go up to the Hi RAM. All the function assumptions doesn't
work for this board.

In fact, what makes the function works at all in this case is a
coincidence. Commit 1a475d39ef introduced a 3GB boundary for the FDT,
down from 4Gb, that is enforced if dram_base is lower than 3072 MiB. For
the Icicle Kit board, memmap[MICROCHIP_PFSOC_DRAM_LO].base is 0x80000000
(2 Gb) and it has a 1Gb size, so it will fall in the conditions to put
the FDT under a 3Gb address, which happens to be exactly at the end of
DRAM_LO. If the base address of the Lo area started later than 3Gb this
function would be unusable by the board. Changing any assumptions inside
riscv_compute_fdt_addr() can also break it by accident as well.

Let's change riscv_compute_fdt_addr() semantics to be appropriate to the
Icicle Kit board and for future boards that might have sparse RAM
topologies to worry about:

- relieve the condition that the dram_base + mem_size area is contiguous,
since this is already not the case today;

- receive an extra 'dram_size' size attribute that refers to a contiguous
RAM block that the board wants the FDT to reside on.

Together with 'mem_size' and 'fdt', which are now now being consumed by a
MachineState pointer, we're able to make clear assumptions based on the
DRAM block and total mem_size available to ensure that the FDT will be put
in a valid RAM address.

bc2c015353 hw/riscv: split fdt address calculation from fdt load
A common trend in other archs is to calculate the fdt address, which is
usually straightforward, and then calling a function that loads the
fdt/dtb by using that address.

riscv_load_fdt() is doing a bit too much in comparison. It's calculating
the fdt address via an elaborated heuristic to put the FDT at the bottom
of DRAM, and "bottom of DRAM" will vary across boards and
configurations, then it's actually loading the fdt, and finally it's
returning the fdt address used to the caller.

Reduce the existing complexity of riscv_load_fdt() by splitting its code
into a new function, riscv_compute_fdt_addr(), that will take care of
all fdt address logic. riscv_load_fdt() can then be a simple function
that just loads a fdt at the given fdt address.

We're also taken the opportunity to clarify the intentions and
assumptions made by these functions. riscv_load_fdt() is now receiving a
hwaddr as fdt_addr because there is no restriction of having to load the
fdt in higher addresses that doesn't fit in an uint32_t.

568e0614d0 hw/riscv/virt.c: rename MachineState 'mc' pointers to 'ms'
We have a convention in other QEMU boards/archs to name MachineState
pointers as either 'machine' or 'ms'. MachineClass pointers are usually
called 'mc'.

The 'virt' RISC-V machine has a lot of instances where MachineState
pointers are named 'mc'. There is nothing wrong with that, but we gain
more compatibility with the rest of the QEMU code base, and easier
reviews, if we follow QEMU conventions.

Rename all 'mc' MachineState pointers to 'ms'. This is a very tedious
and mechanical patch that was produced by doing the following:

- find/replace all 'MachineState *mc' to 'MachineState *ms';
- find/replace all 'mc->fdt' to 'ms->fdt';
- find/replace all 'mc->smp.cpus' to 'ms->smp.cpus';
- replace any remaining occurrences of 'mc' that the compiler complained
about.

d71920d425 virtio-mem: Proper support for preallocation with migration
Ordinary memory preallocation runs when QEMU starts up and creates the
memory backends, before processing the incoming migration stream. With
virtio-mem, we don't know which memory blocks to preallocate before
migration started. Now that we migrate the virtio-mem bitmap early, before
migrating any RAM content, we can safely preallocate memory for all plugged
memory blocks before migrating any RAM content.

This is especially relevant for the following cases:

(1) User errors

With hugetlb/files, if we don't have sufficient backend memory available on
the migration destination, we'll crash QEMU (SIGBUS) during RAM migration
when running out of backend memory. Preallocating memory before actual
RAM migration allows for failing gracefully and informing the user about
the setup problem.

(2) Excluded memory ranges during migration

For example, virtio-balloon free page hinting will exclude some pages
from getting migrated. In that case, we won't crash during RAM
migration, but later, when running the VM on the destination, which is
bad.

To fix this for new QEMU machines that migrate the bitmap early,
preallocate the memory early, before any RAM migration. Warn with old
QEMU machines.

Getting postcopy right is a bit tricky, but we essentially now implement
the same (problematic) preallocation logic as ordinary preallocation:
preallocate memory early and discard it again before precopy starts. During
ordinary preallocation, discarding of RAM happens when postcopy is advised.
As the state (bitmap) is loaded after postcopy was advised but before
postcopy starts listening, we have to discard memory we preallocated
immediately again ourselves.

Note that nothing (not even hugetlb reservations) guarantees for postcopy
that backend memory (especially, hugetlb pages) are still free after they
were freed ones while discarding RAM. Still, allocating that memory at
least once helps catching some basic setup problems.

Before this change, trying to restore a VM when insufficient hugetlb
pages are around results in the process crashing to to a "Bus error"
(SIGBUS). With this change, QEMU fails gracefully:

  qemu-system-x86_64: qemu_prealloc_mem: preallocating memory failed: Bad address
  qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:03.0/virtio-mem-device-early'
  qemu-system-x86_64: load of migration failed: Cannot allocate memory

And we can even introspect the early migration data, including the
bitmap:

3b95a71b22 virtio-mem: Migrate immutable properties early
The bitmap and the size are immutable while migration is active: see
virtio_mem_is_busy(). We can migrate this information early, before
migrating any actual RAM content. Further, all information we need for
sanity checks is immutable as well.

Having this information in place early will, for example, allow for
properly preallocating memory before touching these memory locations
during RAM migration: this way, we can make sure that all memory was
actually preallocated and that any user errors (e.g., insufficient
hugetlb pages) can be handled gracefully.

In contrast, usable_region_size and requested_size can theoretically
still be modified on the source while the VM is running. Keep migrating
these properties the usual, late, way.

Use a new device property to keep behavior of compat machines
unmodified.

"prealloc=on" for the memory backend does not work as expected, as
virtio-mem will simply discard all preallocated memory immediately again.
In the best case, it's an expensive NOP. In the worst case, it's an
unexpected allocation error.

Instead, "prealloc=on" should be specified for the virtio-mem device only,
such that virtio-mem will try preallocating memory before plugging
memory dynamically to the guest. Fail if such a memory backend is
provided.

fd70385d38 migration: Remove unused threshold_size parameter
Until previous commit, save_live_pending() was used for ram.  Now with
the split into state_pending_estimate() and state_pending_exact() it
is not needed anymore, so remove them.

c8df4a7aef migration: Split save_live_pending() into state_pending_*
We split the function into to:

- state_pending_estimate: We estimate the remaining state size without
  stopping the machine.

- state pending_exact: We calculate the exact amount of remaining
  state.

The only "device" that implements different functions for _estimate()
and _exact() is ram.
