1c69cb4e75 ppc/pnv: move root port attach to pnv_phb4_realize()
Creating a root port is something related to the PHB, not the PEC. It
also makes the logic more in line with what pnv-phb3 does.

034d00d485 e1000: set RX descriptor status in a separate operation
The code of setting RX descriptor status field maybe work fine in
previously, however with the update of glibc version, it shows two
issues when guest using dpdk receive packets:

  1. The dpdk has a certain probability getting wrong buffer_addr

     this impact may be not obvious, such as lost a packet once in
     a while

  2. The dpdk may consume a packet twice when scan the RX desc queue
     over again

     this impact will lead a infinite wait in Qemu, since the RDT
     (tail pointer) be inscreased to equal to RDH by unexpected,
     which regard as the RX desc queue is full

Write a whole of RX desc with DD flag on is not quite correct, because
when the underlying implementation of memcpy using XMM registers to
copy e1000_rx_desc (when AVX or something else CPU feature is usable),
the bytes order of desc writing to memory is indeterminacy

We can use full-scale test case to reproduce the issue-2 by
https://github.com/BASM/qemu_dpdk_e1000_test (thanks to Leonid Myravjev)

I also write a POC test case at https://github.com/cdkey/e1000_poc
which can reproduce both of them, and easy to verify the patch effect.

The hw watchpoint also shows that, when Qemu using XMM related instructions
writing 16 bytes e1000_rx_desc, concurrent with DPDK using movb
writing 1 byte status, the final result of writing to memory will be one
of them, if it made by Qemu which DD flag is on, DPDK will consume it
again.

Setting DD status in a separate operation, can prevent the impact of
disorder memory writing by memcpy, also avoid unexpected data when
concurrent writing status by qemu and guest dpdk.

c0e86b7624 xen/pass-through: don't create needless register group
Currently we are creating a register group for the Intel IGD OpRegion
for every device we pass through, but the XEN_PCI_INTEL_OPREGION
register group is only valid for an Intel IGD. Add a check to make
sure the device is an Intel IGD and a check that the administrator has
enabled gfx_passthru in the xl domain configuration. Require both checks
to be true before creating the register group. Use the existing
is_igd_vga_passthrough() function to check for a graphics device from
any vendor and that the administrator enabled gfx_passthru in the xl
domain configuration, but further require that the vendor be Intel,
because only Intel IGD devices have an Intel OpRegion. These are the
same checks hvmloader and libxl do to determine if the Intel OpRegion
needs to be mapped into the guest's memory. Also, move the comment
about trapping 0xfc for the Intel OpRegion where it belongs after
applying this patch.

be9c61da9f xen/pass-through: merge emulated bits correctly
In xen_pt_config_reg_init(), there is an error in the merging of the
emulated data with the host value. With the current Qemu, instead of
merging the emulated bits with the host bits as defined by emu_mask,
the emulated bits are merged with the host bits as defined by the
inverse of emu_mask. In some cases, depending on the data in the
registers on the host, the way the registers are setup, and the
initial values of the emulated bits, the end result will be that
the register is initialized with the wrong value.

To correct this error, use the XEN_PT_MERGE_VALUE macro to help ensure
the merge is done correctly.

This correction is needed to resolve Qemu project issue #1061, which
describes the failure of Xen HVM Linux guests to boot in certain
configurations with passed through PCI devices, that is, when this error
disables instead of enables the PCI_STATUS_CAP_LIST bit of the
PCI_STATUS register of a passed through PCI device, which in turn
disables the MSI-X capability of the device in Linux guests with the end
result being that the Linux guest never completes the boot process.

7a890b7566 include/qemu/host-utils: Remove unused code in the *_overflow wrappers
According to commit cec07c0b61 the code in the #else paths was required
for GCC < 5.0 and Clang < 3.8. We don't support such old compilers
at all anymore, so we can remove these lines now. We keep the wrapper
function, though, since they are easier to read and help to make sure that
the parameters have the right types.

1ec8c2c01e meson.build: Require a recent version of libpng
According to https://gitlab.com/qemu-project/qemu/-/issues/1080#note_998088246
QEMU does not compile with older versions of libpng, so we should check
for a good version in meson.build. According to repology.org, our supported
host target operating systems ship these versions:

             Fedora 35: 1.6.37
     CentOS 8 (RHEL-8): 1.6.34
             Debian 11: 1.6.37
    OpenSUSE Leap 15.3: 1.6.34
      Ubuntu LTS 20.04: 1.6.37
         FreeBSD Ports: 1.6.37
         NetBSD pkgsrc: 1.6.37
         OpenBSD Ports: 1.6.37
              Homebrew: 1.6.37
           MSYS2 mingw: 1.6.37

So it seem reasonable to require at least libpng version 1.6.34 for
our builds.

886dfe9db3 tests: use consistent bandwidth/downtime limits in migration tests
The different migration test cases are using a variety of settings
to ensure convergance/non-convergance. Introduce two helpers to
extra the common functionality and ensure consistency.

  * Non-convergance: 1ms downtime, 30mbs bandwidth
  * Convergance: 30s downtime, 1gbs bandwidth

6843ad8c03 tests: increase migration test converge downtime to 30 seconds
While 1 second might be enough to converge migration on a fast host,
this is not guaranteed, especially if using TLS in the tests without
hardware accelerated crypto available.

Increasing the downtime to 30 seconds should guarantee it can converge
in any sane scenario.

8d4e897a99 tests: wait for migration completion before looking for STOP event
When moving into the convergance phase, the precopy tests will first
look for a STOP event and once found will look for migration completion
status. If the test VM is not converging, the test suite will be waiting
for the STOP event forever. If we wait for the migration completion
status first, then we will trigger the previously added timeout and
prevent the test hanging forever.

276dfd03f0 tests: wait max 120 seconds for migration test status changes
Currently the wait_for_migration_fail and wait_for_migration_complete
functions will spin in an infinite loop checking query-migrate status
to detect a specific change/goal. This is fine when everything goes
to plan, but when the unusual happens, these will hang the test suite
forever.

Any normally executing migration test case normally takes < 1 second
for a state change, with exception of the autoconverge test which
takes about 5 seconds. Taking into account possibility of people
running tests inside TCG, allowing a factor of x20 slowdown gives
a reasonable worst case of 120 seconds. Anything taking longer than
this is a strong sign that the test has hung, or the test should be
rewritten to be faster.

6e131bf69b gitlab: honour QEMU_CI variable in edk2/opensbi jobs
To preserve contributor CI credits we don't want jobs to run by default
unless the QEMU_CI variable is set. For most jobs we can achieve this
using the base template, but the edk2/opensbi jobs are a little special
as they have some complex conditions we can't easily model in the base
template.

We duplicate existing rules and put them under control of QEMU_CI
variable, such that QEMU_CI=1 creates manual jobs and QEMU_CI=2
immediately runs jobs.

Technically we don't need the TCG accelerator to run the

TCG too. Similarly, developers disabling TCG shouldn't
mind much about softfloat3 tests.

4f2c65877c hw/rtc/ls7a_rtc: Fix uninitialied bugs and toymatch writing function
1. Initialize the tm struct in toymatch_write() and ls7a_toy_start() to
   fix uninitialized bugs.
2. Fix toymatch_val_to_time function. By the document, when we calculate
   the expiration year, we should first get current year, and replace the
   0-5 bits with toymatch's 26-31 bits.

Fixes: Coverity CID 1489766, 1489763
