Add some clocks to zynq_slcr
+ the main input clock (ps_clk)
+ the reference clock outputs for each uart (uart0 & 1)
This commit also transitional the slcr to multi-phase reset as it is
required to initialize the clocks correctly.
The clock frequencies are computed using the internal pll & uart configuration
registers and the input ps_clk frequency.

Introduce a function and macro helpers to setup several clocks
in a device from a static array description.
An element of the array describes the clock (name and direction) as
well as the related callback and an optional offset to store the
created object pointer in the device state structure.
The array must be terminated by a special element QDEV_CLOCK_END.

This object may be used to represent a clock inside a clock tree.
A clock may be connected to another clock so that it receives update,
through a callback, whenever the source/parent clock is updated.
Although only the root clock of a clock tree controls the values
(represented as periods) of all clocks in tree, each clock holds
a local state containing the current value so that it can be fetched
independently. It will allows us to fullfill migration requirements
by migrating each clock independently of others.

Ballooning in protected VMs can only be done when the guest shares the
pages it gives to the host. If pages are not shared, the integrity
checks will fail once those pages have been altered and are given back
to the guest.
As we currently do not yet have a solution for this we will continue
like this:
1. We block ballooning now in QEMU (with this patch).
2. Later we will provide a change to virtio that removes the blocker
and adds VIRTIO_F_IOMMU_PLATFORM automatically by QEMU when doing the
protvirt switch. This is OK, as the balloon driver in Linux (the only
supported guest) will refuse to work with the IOMMU_PLATFORM feature
bit set.
3. Later, we can fix the guest balloon driver to accept the IOMMU
feature bit and correctly exercise sharing and unsharing of balloon
pages.

Protected guests are encrypted at rest and need a special boot

Code 8 sets the PV specific IPLB which is retained separately from
those set via code 5.
Code 10 is used to unpack the VM into protected memory, verify its

Signed-off-by: Cornelia Huck <cohuck@redhat.com>
spd_data_generate() splits @ram_size bytes into @nbanks RAM banks of
1 << sz_log2 MiB each, like this:
size = ram_size >> 20; /* work in terms of megabytes */
[...]
nbanks = 1;
while (sz_log2 > max_log2 && nbanks < 8) {
sz_log2--;
nbanks++;
}
Each iteration halves the size of a bank, and increments the number of
banks. Wrong: it should double the number of banks.
The bug goes back all the way to commit b296b664ab "smbus: Add a
helper to generate SPD EEPROM data".
It can't bite because spd_data_generate()'s current users pass only
@ram_size that result in *zero* iterations:
machine RAM size #banks type bank size
fulong2e 256 MiB 1 DDR 256 MiB
sam460ex 2048 MiB 1 DDR2 2048 MiB
1024 MiB 1 DDR2 1024 MiB
512 MiB 1 DDR2 512 MiB
256 MiB 1 DDR2 256 MiB
128 MiB 1 SDR 128 MiB
64 MiB 1 SDR 64 MiB
32 MiB 1 SDR 32 MiB
Apply the obvious, minimal fix. I admit I'm tempted to rip out the
unused (and obviously untested) feature instead, because YAGNI.
Note that this is not the final result, as spd_data_generate() next
increases #banks from 1 to 2 if possible. This is done "to avoid a
bug in MIPS Malta firmware". We don't even use this function with
machine type malta. *Shrug*

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.
spd_data_generate() can pass @errp to error_setg() more than once when
it adjusts both memory size and type. Harmless, because no caller
passes anything that needs adjusting. Until the previous commit,
sam460ex passed types that needed adjusting, but not sizes.
spd_data_generate()'s contract is rather awkward:
If everything's fine, return non-null and don't set an error.
Else, if memory size or type need adjusting, return non-null and
set an error describing the adjustment.
Else, return null and set an error reporting why no data can be
generated.
Its callers treat the error as a warning even when null is returned.
They don't create the "smbus-eeprom" device then. Suspicious.
Since the previous commit, only "everything's fine" can actually
happen. Drop the unused code and simplify the callers. This gets rid
of the error API violation.

Requesting 32 or 64 MiB of RAM with the sam460ex machine type produces
a useless warning:
qemu-system-ppc: warning: Memory size is too small for SDRAM type, adjusting type
This is because sam460ex_init() asks spd_data_generate() for DDR2,
which is impossible, so spd_data_generate() corrects it to DDR.
The warning goes back to commit 08fd99179a "sam460ex: Clean up SPD
EEPROM creation".
Make sam460ex_init() pass the correct SDRAM type to get rid of the

Any sub-page size update to ACPI MRs will be lost during
migration, as we use aligned size in ram_load_precopy() ->
qemu_ram_resize() path. This will result in inconsistency in
FWCfgEntry sizes between source and destination. In order to avoid
this, save and restore them separately during migration.
Up until now, this problem may not be that relevant for x86 as both
ACPI table and Linker MRs gets padded and aligned. Also at present,
qemu_ram_resize() doesn't invoke callback to update FWCfgEntry for
unaligned size changes. But since we are going to fix the
qemu_ram_resize() in the subsequent patch, the issue may become
more serious especially for RSDP MR case.
Moreover, the issue will soon become prominent in arm/virt as well
where the MRs are not padded or aligned at all and eventually have
acpi table changes as part of future additions like NVDIMM hot-add
feature.

With QEMU 4.0 an incompatible change was added to pc_piix, which makes it
practical impossible to migrate domUs started with qemu2 or qemu3 to
newer qemu versions. Commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea
added and enabled a new member "smbus_no_migration_support". In commit
4ab2f2a8aabfea95cc53c64e13b3f67960b27fdf the vmstate_acpi got new
elements, which are conditionally filled. As a result, an incoming
migration expected smbus related data unless smbus migration was
disabled for a given MachineClass. Since first commit forgot to handle
'xenfv', domUs started with QEMU 4.x are incompatible with their QEMU
siblings.
Using other existing machine types, such as 'pc-i440fx-3.1', is not
possible because 'xenfv' creates the 'xen-platform' PCI device at
00:02.0, while all other variants to run a domU would create it at
00:04.0.
To cover both the existing and the broken case of 'xenfv' in a single
qemu binary, a new compatibility variant of 'xenfv-4.2' must be added
which targets domUs started with qemu 4.2. The existing 'xenfv' restores
compatibility of QEMU 5.x with qemu 3.1.
Host admins who started domUs with QEMU 4.x (preferrable QEMU 4.2)
have to use a wrapper script which appends '-machine xenfv-4.2' to
the device-model command line. This is only required if there is no
maintenance window which allows to temporary shutdown the domU and
restart it with a fixed device-model.
The wrapper script is as simple as this:
#!/bin/sh
exec /usr/bin/qemu-system-i386 "$@" -machine xenfv-4.2
With xl this script will be enabled with device_model_override=, see
xl.cfg(5). To live migrate a domU, adjust the existing domU.cfg and pass
it to xl migrate or xl save/restore:
xl migrate -C new-domU.cfg domU remote-host
xl save domU CheckpointFile new-domU.cfg
xl restore new-domU.cfg CheckpointFile
With libvirt this script will be enabled with the <emulator> element in
domU.xml. Use 'virsh edit' prior 'virsh migrate' to replace the existing
<emulator> element to point it to the wrapper script.

The https://makecode.microbit.org/#editor generates slightly weird
.hex files which work fine on a real microbit but causes QEMU to
choke. The reason is extraneous data after the EOF record which causes
the loader to attempt to write a bigger file than it should to the
"rom". According to the HEX file spec an EOF really should be the last
thing we process so lets do that.
