056c5c90c1 Revert "target/arm: Fix usage of MMU indexes when EL3 is AArch32"
This reverts commit 4c2c047469.

This commit tried to fix a problem with our usage of MMU indexes when
EL3 is AArch32, using what it described as a "more complicated
approach" where we share the same MMU index values for Secure PL1&0
and NonSecure PL1&0. In theory this should work, but the change
didn't account for (at least) two things:

(1) The design change means we need to flush the TLBs at any point
where the CPU state flips from one to the other.  We already flush
the TLB when SCR.NS is changed, but we don't flush the TLB when we
take an exception from NS PL1&0 into Mon or when we return from Mon
to NS PL1&0, and the commit didn't add any code to do that.

(2) The ATS12NS* address translate instructions allow Mon code (which
is Secure) to do a stage 1+2 page table walk for NS.  I thought this
was OK because do_ats_write() does a page table walk which doesn't
use the TLBs, so because it can pass both the MMU index and also an
ARMSecuritySpace argument we can tell the table walk that we want NS
stage1+2, not S.  But that means that all the code within the ptw
that needs to find e.g.  the regime EL cannot do so only with an
mmu_idx -- all these functions like regime_sctlr(), regime_el(), etc
would need to pass both an mmu_idx and the security_space, so they
can tell whether this is a translation regime controlled by EL1 or
EL3 (and so whether to look at SCTLR.S or SCTLR.NS, etc).

In particular, because regime_el() wasn't updated to look at the
ARMSecuritySpace it would return 1 even when the CPU was in Monitor
mode (and the controlling EL is 3).  This meant that page table walks
in Monitor mode would look at the wrong SCTLR, TCR, etc and would
generally fault when they should not.

Rather than trying to make the complicated changes needed to rescue
the design of 4c2c047469, we revert it in order to instead take the
route that that commit describes as "the most straightforward" fix,
where we add new MMU indexes EL30_0, EL30_3, EL30_3_PAN to correspond
to "Secure PL1&0 at PL0", "Secure PL1&0 at PL1", and "Secure PL1&0 at
PL1 with PAN".

This revert will re-expose the "spurious alignment faults in
Secure PL0" issue #2326; we'll fix it again in the next commit.

bc0b360def softfloat: Remove fallback rule from pickNaN()
Now that all targets have been converted to explicitly set a NaN
propagation rule, we can remove the set of target ifdefs (which now
list every target) and clean up the references to fallback behaviour
for float_2nan_prop_none.

The "default" case in the switch will catch any remaining places
where status->float_2nan_prop_rule was not set by the target.

c18a13edce target/microblaze: Move setting of float rounding mode to reset
Although the floating point rounding mode for Microblaze is always
nearest-even, we cannot set it just once in the CPU initfn.  This is
because env->fp_status is in the part of the CPU state struct that is
zeroed on reset.

Move the call to set_float_rounding_mode() into the reset fn.

(This had no guest-visible effects because it happens that the
float_round_nearest_even enum value is 0, so when the struct was
zeroed it didn't corrupt the setting.)

80de5f24e0 target/xtensa: Factor out calls to set_use_first_nan()
In xtensa we currently call set_use_first_nan() in a lot of
places where we want to switch the NaN-propagation handling.
We're about to change the softfloat API we use to do that,
so start by factoring all the calls out into a single
xtensa_use_first_nan() function.

The bulk of this change was done with
 sed -i -e 's/set_use_first_nan(\([^,]*\),[^)]*)/xtensa_use_first_nan(env, \1)/'  target/xtensa/fpu_helper.c

65c1c039cd target/sparc: Move cpu_put_fsr(env, 0) call to reset
Currently we call cpu_put_fsr(0) in sparc_cpu_realizefn(), which
initializes various fields in the CPU struct:
 * fsr_cexc_ftt
 * fcc[]
 * fsr_qne
 * fsr
It also sets the rounding mode in env->fp_status.

This is largely pointless, because when we later reset the CPU
this will zero out all the fields up until the "end_reset_fields"
label, which includes all of these (but not fp_status!)

Move the cpu_put_fsr(env, 0) call to reset, because that expresses
the logical requirement: we want to reset FSR to 0 on every reset.
This isn't a behaviour change because the fields are all zero anyway.

The situation with FPA11 emulation in linux-user is a little odd, and
arguably "correct" behaviour there would be to exactly match a real
Linux kernel's FPA11 emulation.  However FPA11 emulation is
essentially dead at this point and so it seems better to continue
with QEMU's current behaviour and leave a comment describing the
situation.

8a132968b2 softfloat: Allow 2-operand NaN propagation rule to be set at runtime
IEEE 758 does not define a fixed rule for which NaN to pick as the
result if both operands of a 2-operand operation are NaNs.  As a
result different architectures have ended up with different rules for
propagating NaNs.

QEMU currently hardcodes the NaN propagation logic into the binary
because pickNaN() has an ifdef ladder for different targets.  We want
to make the propagation rule instead be selectable at runtime,
because:
 * this will let us have multiple targets in one QEMU binary
 * the Arm FEAT_AFP architectural feature includes letting
   the guest select a NaN propagation rule at runtime
 * x86 specifies different propagation rules for x87 FPU ops
   and for SSE ops, and specifying the rule in the float_status
   would let us emulate this, instead of wrongly using the
   x87 rules everywhere

In this commit we add an enum for the propagation rule, the field in
float_status, and the corresponding getters and setters.  We change
pickNaN to honour this, but because all targets still leave this
field at its default 0 value, the fallback logic will pick the rule
type with the old ifdef ladder.

It's valid not to set a propagation rule if default_nan_mode is
enabled, because in that case there's no need to pick a NaN; all the
callers of pickNaN() catch this case and skip calling it.  So we can
already assert that we don't get into the "no rule defined" codepath
for our four targets which always set default_nan_mode: Hexagon,
RiscV, SH4 and Tricore, and for the one target which does not have FP
at all: avr.  These targets will not need to be updated to call
set_float_2nan_prop_rule().

380f7268b7 tests/functional: Convert the OrangePi tests to the functional framework
Move the OrangePi tests from tests/avocado/boot_linux_console.py into
a new file dedicated for OrangePi tests in the functional framework
and update the hash sums of the assets to sha256 along the way.
For the buildroot image and the Armbian image, we've got to switch to
a newer version since the old images have been removed from the server,
and the NetBSD image has been moved to the archive, so we need to update
this URL as well.

bc9da794cc hw/s390x: Re-enable the pci-bridge device on s390x
Commit e779e5c05a ("hw/pci-bridge: Add a Kconfig switch for the
normal PCI bridge") added a config switch for the pci-bridge, so
that the device is not included in the s390x target anymore (since
the pci-bridge is not really useful on s390x).

However, it seems like libvirt is still adding pci-bridge devices
automatically to the guests' XML definitions (when adding a PCI
device to a non-zero PCI bus), so these guests are now broken due
to the missing pci-bridge in the QEMU binary.

To avoid disruption of the users, let's re-enable the pci-bridge
device on s390x for the time being.

786bc22552 tests/functional: make cached asset files read-only
This ensures that if a functional test runs QEMU with a writable

results in a clear error:

Cirrus-CI stopped providing the possibility to run macOS 15 jobs.
Quoting https://cirrus-ci.org/guide/macOS/ :

 "Cirrus CI Cloud only allows ghcr.io/cirruslabs/macos-runner:sonoma image ..."

If you still try to run a Sequoia image, it gets automatically "upgraded"
to Sonoma instead. So the macos-15 job in the QEMU CI now does not
make sense anymore, thus let's remove it.

47b54e15bb target/loongarch: Add steal time support on migration
With pv steal time supported, VM machine needs get physical address
of each vcpu and notify new host during migration. Here two
functions kvm_get_stealtime/kvm_set_stealtime, and guest steal time
physical address is only updated on KVM_PUT_FULL_STATE stage.

6495c577bd hw/loongarch/boot: Use warn_report when no kernel filename
When we run “qemu-system-loongarch64 -qmp stdio -vnc none -S”,
we get an error message “Need kernel filename” and then we can't use qmp cmd to query some information.
So, we just throw a warning and then the cpus starts running from address VIRT_FLASH0_BASE.

6edd2a9bec target/loongarch/kvm: Implement LoongArch PMU extension
Implement PMU extension for LoongArch kvm mode. Use OnOffAuto type
variable pmu to check the PMU feature. If the PMU Feature is not supported
with KVM host, it reports error if there is pmu=on command line.

If there is no any command line about pmu parameter, it checks whether
KVM host supports the PMU Feature and set the corresponding value in cpucfg.

This patch is based on lbt patch located at
  https://lore.kernel.org/qemu-devel/20240904061859.86615-1-maobibo@loongson.cn

c23a53d894 target/loongarch: Add loongson binary translation feature
Loongson Binary Translation (LBT) is used to accelerate binary
translation, which contains 4 scratch registers (scr0 to scr3), x86/ARM
eflags (eflags) and x87 fpu stack pointer (ftop).

Now LBT feature is added in kvm mode, not supported in TCG mode since
it is not emulated. Feature variable lbt is added with OnOffAuto type,
If lbt feature is not supported with KVM host, it reports error if there
is lbt=on command line.

If there is no any command line about lbt parameter, it checks whether
KVM host supports lbt feature and set the corresponding value in cpucfg.
