Peter Maydell 631f46d4ea reset: Add RESET_TYPE_SNAPSHOT_LOAD
Some devices and machines need to handle the reset before a vmsave
snapshot is loaded differently -- the main user is the handling of
RNG seed information, which does not want to put a new RNG seed into
a ROM blob when we are doing a snapshot load.

Currently this kind of reset handling is supported only for:
 * TYPE_MACHINE reset methods, which take a ShutdownCause argument
 * reset functions registered with qemu_register_reset_nosnapshotload

To allow a three-phase-reset device to also distinguish "snapshot
load" reset from the normal kind, add a new ResetType
RESET_TYPE_SNAPSHOT_LOAD. All our existing reset methods ignore
the reset type, so we don't need to update any device code.

Add the enum type, and make qemu_devices_reset() use the
right reset type for the ShutdownCause it is passed. This
allows us to get rid of the device_reset_reason global we
were using to implement qemu_register_reset_nosnapshotload().

Peter Maydell ad80e36744 hw, target: Add ResetType argument to hold and exit phase methods
We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

Peter Maydell aadea887f4 scripts/coccinelle: New script to add ResetType to hold and exit phases
We pass a ResetType argument to the Resettable class enter phase
method, but we don't pass it to hold and exit, even though the
callsites have it readily available.  This means that if a device
cared about the ResetType it would need to record it in the enter
phase method to use later on.  We should pass the type to all three
of the phase methods to avoid having to do that.

This coccinelle script adds the ResetType argument to the hold and
exit phases of the Resettable interface.

The first part of the script (rules holdfn_assigned, holdfn_defined,
exitfn_assigned, exitfn_defined) update implementations of the
interface within device models, both to change the signature of their
method implementations and to pass on the reset type when they invoke
reset on some other device.

The second part of the script is various special cases:
 * method callsites in resettable_phase_hold(), resettable_phase_exit()
   and device_phases_reset()
 * updating the typedefs for the methods
 * isl_pmbus_vr.c has some code where one device's reset method directly
   calls the implementation of a different device's method

Peter Maydell 1e0f2b38ac hw/misc: Don't special case RESET_TYPE_COLD in npcm7xx_clk, gcr
The npcm7xx_clk and npcm7xx_gcr device reset methods look at
the ResetType argument and only handle RESET_TYPE_COLD,
producing a warning if another reset type is passed. This
is different from how every other three-phase-reset method
we have works, and makes it difficult to add new reset types.

A better pattern is "assume that any reset type you don't know
about should be handled like RESET_TYPE_COLD"; switch these
devices to do that. Then adding a new reset type will only
need to touch those devices where its behaviour really needs
to be different from the standard cold reset.

Peter Maydell a6819c1bd0 linux-user/flatload.c: Remove unused bFLT shared-library and ZFLAT code
Ever since the bFLT format support was added in 2006, there has been
a chunk of code in the file guarded by CONFIG_BINFMT_SHARED_FLAT
which is supposedly for shared library support.  This is not enabled
and it's not possible to enable it, because if you do you'll run into
the "#error needs checking" in the calc_reloc() function.

Similarly, CONFIG_BINFMT_ZFLAT exists but can't be enabled because of
an "#error code needs checking" in load_flat_file().

This code is obviously unfinished and has never been used; nobody in
the intervening 18 years has complained about this or fixed it, so
just delete the dead code.  If anybody ever wants the feature they
can always pull it out of git, or (perhaps better) write it from
scratch based on the current Linux bFLT loader rather than the one of
18 years ago.

Anastasia Belova c3a68dfd19 hw/dma: avoid apparent overflow in soc_dma_set_request
In soc_dma_set_request() we try to set a bit in a uint64_t, but we
do it with "1 << ch->num", which can't set any bits past 31;
any use for a channel number of 32 or more would fail due to
integer overflow.

This doesn't happen in practice for our current use of this code,
because the worst case is when we call soc_dma_init() with an
argument of 32 for the number of channels, and QEMU builds with
-fwrapv so the shift into the sign bit is well-defined. However,
it's obviously not the intended behaviour of the code.

Add casts to force the shift to be done as 64-bit arithmetic,
allowing up to 64 channels.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Jinjie Ruan 5ae47f7aec hw/arm/virt: Enable NMI support in the GIC if the CPU has FEAT_NMI
If the CPU implements FEAT_NMI, then turn on the NMI support in the
GICv3 too.  It's permitted to have a configuration with FEAT_NMI in
the CPU (and thus NMI support in the CPU interfaces too) but no NMI
support in the distributor and redistributor, but this isn't a very
useful setup as it's close to having no NMI support at all.

We don't need to gate the enabling of NMI in the GIC behind a
machine version property, because none of our current CPUs
implement FEAT_NMI, and '-cpu max' is not something we maintain
migration compatibility across versions for. So we can always
enable the GIC NMI support when the CPU has it.

Neither hvf nor KVM support NMI in the GIC yet, so we don't enable
it unless we're using TCG.

Jinjie Ruan 6aa2041561 target/arm: Add PSTATE.ALLINT
When PSTATE.ALLINT is set, an IRQ or FIQ interrupt that is targeted to
ELx, with or without superpriority is masked. As Richard suggested, place
ALLINT bit in PSTATE in env->pstate.

In the pseudocode, AArch64.ExceptionReturn() calls SetPSTATEFromPSR(), which
treats PSTATE.ALLINT as one of the bits which are reinstated from SPSR to
PSTATE regardless of whether this is an illegal exception return or not. So
handle PSTATE.ALLINT the same way as PSTATE.DAIF in the illegal_return exit
path of the exception_return helper. With the change, exception entry and
return are automatically handled.

Maksim Davydov b928505d39 scripts: add script to compare compatibility properties
This script runs QEMU to obtain compat_props of machines and default
values of different types of drivers to produce comparison table. This
table can be used to compare machine types to choose the most suitable
machine or compare binaries to be sure that migration to the newer version
will save all device properties. Also the json or csv format of this
table can be used to check does a new machine affect the previous ones by
comparing tables with and without the new machine.

Default values (that will be used without machine compat_props) of
properties are needed to fill "holes" in the table (one machine has
the property but another machine not. For instance, 2.12 machine has
`{ "EPYC-" TYPE_X86_CPU, "xlevel", "0x8000000a" }`, but compat_pros of
3.1 machine doesn't have it. Thus, to compare these machines we need to
get unknown value of "EPYC-x86_64-cpu-xlevel" for 3.1 machine. These
unknown values in the table are called "holes". To get values for these
"holes" the script uses list of appropriate methods.)

Notes:
* Some init values from the devices can't be available like properties
  from virtio-9p when configure has --disable-virtfs. This situations will
  be seen in the table as "unavailable driver".
* Default values can be obtained in an unobvious way, like x86 features.
  If the script doesn't know how to get property default value to compare
  one machine with another it fills "holes" with "unavailable method". This
  is done because script uses whitelist model to get default values of
  different types. It means that the method that can't be applied to a new
  type that can crash this script. It is better to get an "unavailable
  driver" when creating a new machine with new compatible properties than
  to break this script. So it turns out a more stable and generic script.
* If the default value can't be obtained because this property doesn't
  exist or because this property can't have default value, appropriate
  "hole" will be filled by "unknown property" or "no default value"
* If the property is applied to the abstract class, the script collects
  default values from all child classes and prints all these classes
* Raw table (--raw flag) should be used with json/csv parameters for
  scripts and etc. Human-readable (default) format contains transformed
  and simplified values and it doesn't contain lines with the same values
  in columns

./scripts/compare-machine-types.py --mt pc-q35-6.2 pc-q35-7.1

This patch adds the ability to get list of all the compat_props of the
corresponding supported machines for their comparison via new optional
argument of "query-machines" command. Since information on compatibility
properties can increase the command output by a factor of 40, add an
argument to enable it, default off.

Thomas Huth 641b1efe01 tests: Update our CI to use CentOS Stream 9 instead of 8
RHEL 9 (and thus also the derivatives) have been available since two
years now, so according to QEMU's support policy, we can drop the active
support for the previous major version 8 now.

Another reason for doing this is that Centos Stream 8 will go EOL soon:

https://blog.centos.org/2023/04/end-dates-are-coming-for-centos-stream-8-and-centos-linux-7/

  "After May 31, 2024, CentOS Stream 8 will be archived
   and no further updates will be provided."

Thus upgrade our CentOS Stream container to major version 9 now.

Thomas Huth 2355d18c79 tests/docker/dockerfiles: Run lcitool-refresh after the lcitool update
This update adds the removing of the EXTERNALLY-MANAGED marker files
that has been added to the lcitool recently.

Quoting Daniel:
"For those who don't know, python now commonly blocks the ability to
run 'pip install' outside of a venv. This generally makes sense for
a precious installation environment. Our containers are disposable
though, so a venv has no benefit. Removing the 'EXTERNALLY-MANAGED'
allows the historical arbitrary use of 'pip' outside a venv.
lcitool just does this unconditionally given the containers are
not precious."
