The restrictions here (which are checked at pre-plug time) are PAPR
specific, rather than being inherent to the NVDIMM devices. Adjust the
error messages to be clearer about this.

The pseries machine does not support NVDIMM modules without label.
Attempting to do so, even if the overall block size is aligned with
256MB, will seg fault the guest kernel during NVDIMM probe. This
can be avoided by forcing 'label-size' to always be present for
sPAPR NVDIMMs.
The verification was put before the alignment check because the
presence of label-size affects the alignment calculation, so
it's not optimal to warn the user about an alignment error,
then about the lack of label-size, then about a new alignment
error when the user sets a label-size.

Currently, we can't properly handle unplug of NVLink2 devices, because we
don't have code to tear down their special memory resources. There's not
a lot of impetus to implement that: since hardware NVLink2 devices can't
be hot unplugged, the guest side drivers don't usually support unplug
anyway.
Therefore, simply prevent unplug of NVLink2 devices.

The CAS reboot flag is false by default and all the locations that
could set it to true have been dropped. This means that all code
blocks depending on the flag being set is dead code and the other
code blocks should be executed always.
Just do that and drop the now uneeded CAS reboot flag. Fix a
comment on the way to make checkpatch happy.

At the moment "ibm,client-architecture-support" ("CAS") is implemented
in SLOF and QEMU assists via the custom H_CAS hypercall which copies
an updated flatten device tree (FDT) blob to the SLOF memory which
it then uses to update its internal tree.
When we enable the OpenFirmware client interface in QEMU, we won't need
to copy the FDT to the guest as the client is expected to fetch
the device tree using the client interface.
This moves FDT rebuild out to a separate helper which is going to be
called from the "ibm,client-architecture-support" handler and leaves
writing FDT to the guest in the H_CAS handler.
This should not cause any behavioral change.

The guest can select the MMU mode by setting bits 0-1 of byte 24
in OV5 to to 0b00 for hash or 0b01 for radix. As required by the
architecture, we terminate the boot process if any other value
is found there.
The usual way to negotiate features in OV5 is basically ANDing
the bitfield provided by the guest and the bitfield of features
supported by QEMU, previously populated at machine init.
For some not documented reason, MMU is treated differently : bit 1
of byte 24 (the radix/hash bit) is cleared from the guest OV5 and
explicitely set in the final negotiated OV5 if radix was requested.
Since the only expected input from the guest is the radix/hash bit
being set or not, it seems more appropriate to handle this like we
do for XIVE.
Set the radix bit in spapr->ov5 at machine init if it has a chance
to work (ie. power9, either TCG or a radix capable KVM) and rely
exclusively on spapr_ovec_intersect() to set the radix bit in
spapr->ov5_cas.

Rather than have the helper take an optional vector address
override, instead have its caller modify env->nip itself.

We currently check if some capability in OV5 was removed by the guest
since the previous CAS, and we trigger a CAS reboot in that case. This
was required because it could call for a device-tree property or node
removal, that we didn't support until recently (see commit 6787d27b04a7
"spapr: add option vector handling in CAS-generated resets" for details).
Now that we render a full FDT at CAS and that SLOF is able to handle
node removal, we don't need to do a CAS reset in this case anymore.
Also, this check can only return true if the guest has already called
CAS since the last full system reset (otherwise spapr->ov5_cas is
empty). Linux doesn't do that so this can be considered as dead code
for the vast majority of existing setups.
Drop the check. Since the only use of the ov5_cas_old variable is
precisely the check itself, drop the variable as well.

Microsoft introduced this ACPI table to avoid Windows guests performing
various workarounds for device erratas. As the virtual device emulated
by VMM may not have the errata.
Currently, WAET allows hypervisor to inform guest about two
specific behaviors: One for RTC and the other for ACPI PM timer.
Support for WAET have been introduced since Windows Vista. This ACPI
table is also exposed by other common hypervisors by default, including:
VMware, GCP and AWS.
This patch adds WAET ACPI Table to QEMU.
We set "ACPI PM timer good" bit in "Emualted Device Flags" field to
indicate that the ACPI PM timer has been enhanced to not require
multiple reads to obtain a reliable value.
This results in improving the performance of Windows guests that use
ACPI PM timer by avoiding unnecessary VMExits caused by these multiple
reads.

As per ACPI spec 6.3, Table 19-419 Object Conversion Rules, if
the Buffer Field <= to the size of an Integer (in bits), it will
be treated as an integer. Moreover, the integer size depends on
DSDT tables revision number. If revision number is < 2, integer
size is 32 bits, otherwise it is 64 bits. Current NVDIMM common
DSM aml code (NCAL) uses CreateField() for creating DSM output
buffer. This creates an issue in arm/virt platform where DSDT
revision number is 2 and results in DSM buffer with a wrong
size(8 bytes) gets returned when actual length is < 8 bytes.
This causes guest kernel to report,
"nfit ACPI0012:00: found a zero length table '0' parsing nfit"
In order to fix this, aml code is now modified such that it builds
the DSM output buffer in a byte by byte fashion when length is
smaller than Integer size.

With virtio-vga, pci bar are reordered. Bar #2 is used for compatibility
with stdvga. By default, bar #2 is used by virtio modern io bar.
This bar is the last one introduce in the virtio pci bar layout and it's
crushed by the virtio-vga reordering. So virtio-vga and
modern-pio-notify are incompatible because virtio-vga failed to
initialize with this option.
This fix sets the modern io bar to the bar #5 to avoid conflict.

pxa2xx_timer_tick4() takes an opaque pointer, then calls
pxa2xx_timer_update4(), so the static analyzer can not
verify that the 'n < 8':
425 static void pxa2xx_timer_tick4(void *opaque)
426 {
427 PXA2xxTimer4 *t = (PXA2xxTimer4 *) opaque;
428 PXA2xxTimerInfo *i = (PXA2xxTimerInfo *) t->tm.info;
429
430 pxa2xx_timer_tick(&t->tm);
433 if (t->control & (1 << 6))
434 pxa2xx_timer_update4(i, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL), t->tm.num - 4);
135 static void pxa2xx_timer_update4(void *opaque, uint64_t now_qemu, int n)
136 {
137 PXA2xxTimerInfo *s = (PXA2xxTimerInfo *) opaque;
140 static const int counters[8] = { 0, 0, 0, 0, 4, 4, 6, 6 };
142
143 if (s->tm4[n].control & (1 << 7))
144 counter = n;
145 else
146 counter = counters[n];
Add an assert() to give the static analyzer a hint, this fixes a
warning reported by Clang static code analyzer:
CC hw/timer/pxa2xx_timer.o
hw/timer/pxa2xx_timer.c:146:17: warning: Assigned value is garbage or undefined
