xics/kvm: Always set the MASKED bit if interrupt is masked
pseries: Update SLOF firmware image
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
The ics_set_kvm_state_one() function is called either to restore the
state of an interrupt source during migration or to set the interrupt
source to a default state during reset.
Since always, ie. 2013, the code only sets the MASKED bit if the 'current
priority' and the 'saved priority' are different. This is likely true
when restoring an interrupt that had been previously masked with the
ibm,int-off RTAS call. However this is always false in the case of
reset since both 'current priority' and 'saved priority' are equal to
0xff, and the MASKED bit is never set.
The legacy KVM XICS device gets away with that because it ends updating
its internal structure the same way, whether the MASKED bit is set or
the priority is 0xff.
The XICS-on-XIVE device for POWER9 is different. It sticks to the KVM
documentation [1] and _really_ relies on the MASKED bit to correctly
set. If not, it will configure the interrupt source in the XIVE HW, even
though the guest hasn't configured the interrupt yet. This disturbs the
complex logic implemented in XICS-on-XIVE and may result in the loss of
subsequent queued events.
Always set the MASKED bit if interrupt is masked as expected by the KVM
XICS-on-XIVE device. This has no impact on the legacy KVM XICS.

The annotated style json we use in QMP documentation is not strict json
and depending on the version of Sphinx (2.0+) or Pygments installed,
might cause the build to fail.
Use the new QMP lexer.
Further, some versions of Sphinx can not apply custom lexers to "code"
directives and require the use of "code-block" directives instead, so
make that change at this time as well.
Tested under:
- Sphinx 1.3.6 and Pygments 2.4
- Sphinx 1.7.6 and Pygments 2.2 (Fedora 29 packages)

Sphinx, through Pygments, does not like annotated json examples very
much. In some versions of Sphinx (1.7), it will render the non-json
portions of code blocks in red, but in newer versions (2.0) it will
throw an exception and not highlight the block at all. Though we can
suppress this warning, it doesn't bring back highlighting on non-strict
json blocks.
We can alleviate this by creating a custom lexer for QMP examples that
allows us to properly highlight these examples in a robust way, keeping
our directionality and elision notations.

This reverts commit 3ae0343db6.
Stephen Checkoway noticed commit 3ae0343db6 is incorrect.
This commit state all parallel flashes are limited to 16-bit
accesses, however the x32 configuration exists in some models,
such the Cypress S29CL032J, which CFI Device Geometry Definition
announces:
CFI ADDR DATA
0x28,0x29 = 0x0003 (x32-only asynchronous interface)
Guests should not be affected by the previous change, because
QEMU does not announce itself as x32 capable:
/* Flash device interface (8 & 16 bits) */
pfl->cfi_table[0x28] = 0x02;
pfl->cfi_table[0x29] = 0x00;
Commit 3ae0343db6 does not restrict the bus to 16-bit accesses,
but restrict the implementation as 16-bit access max, so a guest
32-bit access will result in 2x 16-bit calls.
Now, we have 2 boards that register the flash device in 32-bit
access:
- PPC: taihu_405ep
The CFI id matches the S29AL008J that is a 1MB in x16, while
the code QEMU forces it to be 2MB, and checking Linux it expects
a 4MB flash.
- ARM: Digic4
While the comment says "Samsung K8P3215UQB 64M Bit (4Mx16)",
this flash is 32Mb (2MB). Also note the CFI id does not match
the comment.
To avoid unexpected side effect, we revert commit 3ae0343db6,
and will clean the board code later.

When the 'cont' command resumes guest execution the vm change state
handlers are invoked. Unfortunately there is no explicit ordering
between classic qemu_add_vm_change_state_handler() callbacks. When two
layers of code both use vm change state handlers, we don't control which
handler runs first.
virtio-scsi with iothreads hits a deadlock when a failed SCSI command is
restarted and completes before the iothread is re-initialized.
This patch uses the new qdev_add_vm_change_state_handler() API to
guarantee that virtio-scsi's virtio change state handler executes before
the SCSI bus children. This way DMA is restarted after the iothread has
re-initialized.

In the virt machine, we support TrustZone being either present or
absent, and so the code must deal with the secure_sysmem pointer
possibly being NULL. In the sbsa-ref machine, TrustZone is always
present, but some code and comments copied from virt still treat
it as possibly not being present.
This causes Coverity to complain (CID 1407287) that we check
secure_sysmem for being NULL after an unconditional dereference.
Simplify the code so that instead of initializing the variable
to NULL, unconditionally assigning it, and then testing it for NULL,
we just initialize it correctly in the variable declaration and
then assume it to be non-NULL. We also delete a comment which
only applied to the non-TrustZone config.

The test aarch64 kernel is in an array defined with
unsigned char aarch64_kernel[] = { [...] }
which means it could be any size; currently it's quite small.
However we write it to a file using init_bootfile(), which
writes exactly 512 bytes to the file. This will break if
we ever end up with a kernel larger than that, and will
read garbage off the end of the array in the current setup
where the kernel is smaller.
Make init_bootfile() take an argument giving the length of
the data to write. This allows us to use it for all architectures
(previously s390 had a special-purpose init_bootfile_s390x
which hardcoded the file to write so it could write the
correct length). We assert that the x86 bootfile really is
exactly 512 bytes as it should be (and as we were previously
just assuming it was).
This was detected by the clang-7 asan:

The S390_FEAT_AP_QUEUE_INTERRUPT_CONTROL, CPU facility indicates
whether the PQAP instruction with the AQIC command is available
to the guest.
This feature will be enabled only if the AP instructions are
available on the linux host and AQIC facility is installed on
the host.
This feature must be turned on from userspace to intercept AP

or

Right now AP pass-through devices do not support migration,

This is because in ioapic_eoi_broadcast function, we uses 'vector' to
index the 's->irq_eoi'. To fix this, we should uses the irq number.

When vCPU is in VMX operation and enters SMM mode,
it temporarily exits VMX operation but KVM maintained nested-state
still stores the VMXON region physical address, i.e. even when the
vCPU is in SMM mode then (nested_state->hdr.vmx.vmxon_pa != -1ull).
Therefore, there is no need to explicitly check for
KVM_STATE_NESTED_SMM_VMXON to determine if it is necessary
to save nested-state as part of migration stream.

When minikconf writes config-devices.mak, it includes all variables including
those from MINIKCONF_ARGS. This causes values from config-host.mak to "stick" to
the ones used in generating config-devices.mak, because config-devices.mak is
included after config-host.mak. Avoid this by omitting assignments coming
from the command line in the output of minikconf.

Commit 2d384d7c8 broken the build when built with:
configure --without-default-devices --disable-user
The reason was the conversion of cpu->hyperv_synic to
cpu->hyperv_synic_kvm_only although the rest of the patch introduces a
feature checking mechanism. So I've fixed the KVM_EXIT_HYPERV_SYNIC in
hyperv-stub to do the same feature check as in the real hyperv.c

irq_eoi is used to count the number of irq injected during eoi
broadcast. It should be set to 0 when updating the ioapic's redirect
table entry.

This is an replacement work of Yan Zhao's patch:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg625340.html
vtd_address_space_unmap() will do proper page mask alignment to make
sure each IOTLB message will have correct masks for notification
messages (2^N-1), but sometimes it can be expanded to even supercede
the registered range. That could lead to unexpected UNMAP of already
mapped regions in some other notifiers.
Instead of doing mindless expension of the start address and address
mask, we split the range into smaller ones and guarantee that each
small range will have correct masks (2^N-1) and at the same time we
should also try our best to generate as less IOTLB messages as
possible.
