ee48fef06c aspeed/smc: Reintroduce "dram-base" property for AST2700
The Aspeed SMC device model use to have a 'sdram_base' property. It
was removed by commit d177892d4a ("aspeed/smc: Remove unused
"sdram-base" property") because previous changes simplified the DMA
transaction model to use an offset in RAM and not the physical
address.

The AST2700 SoC has larger address space (64-bit) and a new register
DMA DRAM Side Address High Part (0x7C) is introduced to deal with the
high bits of the DMA address. To be able to compute the offset of the
DMA transaction, as done on the other SoCs, we will need to know where
the DRAM is mapped in the address space. Re-introduce a "dram-base"
property to hold this value.

f6fe9fea99 migration/multifd: implement qpl compression and decompression
QPL compression and decompression will use IAA hardware path if the IAA
hardware is available. Otherwise the QPL library software path is used.

The hardware path will automatically fall back to QPL software path if
the IAA queues are busy. In some scenarios, this may happen frequently,
such as configuring 4 channels but only one IAA device is available. In
the case of insufficient IAA hardware resources, retry and fallback can
help optimize performance:

 1. Retry + SW fallback:
    total time: 14649 ms
    downtime: 25 ms
    throughput: 17666.57 mbps
    pages-per-second: 1509647

 2. No fallback, always wait for work queues to become available
    total time: 18381 ms
    downtime: 25 ms
    throughput: 13698.65 mbps
    pages-per-second: 859607

If both the hardware and software paths fail, the uncompressed page is
sent directly.

add the Query Processing Library (QPL) compression method

Introduce the qpl as a new multifd migration compression method, it can
use In-Memory Analytics Accelerator(IAA) to accelerate compression and
decompression, which can not only reduce network bandwidth requirement
but also reduce host compression and decompression CPU overhead.

How to enable qpl compression during migration:
migrate_set_parameter multifd-compression qpl

There is no qpl compression level parameter added since it only supports
level one, users do not need to specify the qpl compression level.

26a09ead73 tests/tcg/s390x: Allow specifying extra QEMU options on the command line
The use case for this is `make check-tcg EXTFLAGS="-accel kvm"`,
which allows validating the system TCG testcases on real hardware.
EXTFLAGS name is borrowed from tests/tcg/xtensa/Makefile.softmmu-target.
While at it, use += instead of = in order to be consistent with the
other architectures.

e08f6e0b9f tests/qtest/x86: check for availability of older cpu models before running tests
It is better to check if some older cpu models like 486, athlon, pentium,
penryn, phenom, core2duo etc are available before running their corresponding
tests. Some downstream distributions may no longer support these older cpu
models.

Signature of add_feature_test() has been modified to return void as
FeatureTestArgs* was not used by the caller.

One minor correction. Replaced 'phenom' with '486' in the test
'x86/cpuid/auto-level/phenom/arat' matching the cpu used.

Added a new test api qtest_has_cpu_model() in order to check availability of
some cpu models in the current QEMU binary. The specific architecture of the
QEMU binary is selected using the QTEST_QEMU_BINARY environment variable.
This api would be useful to run tests against some older cpu models after
checking if QEMU actually supported these models.

c0df9563a3 target/i386: replace NoSeg special with NoLoadEA
This is a bit more generic, as it can be applied to MPX as well.

4e2dc59cf9 target/i386: change X86_ENTRYwr to use T0, use it for moves
Just like X86_ENTRYr, X86_ENTRYwr is easily changed to use only T0.
In this case, the motivation is to use it for the MOV instruction
family.  The case when you need to preserve the input value is the
odd one, as it is used basically only for BLS* instructions.

c2b6b6a65a target/i386: change X86_ENTRYr to use T0
I am not sure why I made it use T1.  It is a bit more symmetric with
respect to X86_ENTRYwr (which uses T0 for the "w"ritten operand
and T1 for the "r"ead operand), but it is also less flexible because it
does not let you apply zextT0/sextT0.

e628387cf9 target/i386: put BLS* input in T1, use generic flag writeback
This makes for easier cpu_cc_* setup, and not using set_cc_op()
should come in handy if QEMU ever implements APX.

cc155f1971 target/i386: rewrite flags writeback for ADCX/ADOX
Avoid using set_cc_op() in preparation for implementing APX; treat
CC_OP_EFLAGS similar to the case where we have the "opposite" cc_op
(CC_OP_ADOX for ADCX and CC_OP_ADCX for ADOX), except the resulting
cc_op is not CC_OP_ADCOX. This is written easily as two "if"s, whose
conditions are both false for CC_OP_EFLAGS, both true for CC_OP_ADCOX,
and one each true for CC_OP_ADCX/ADOX.

The new logic also makes it easy to drop usage of tmp0.

4228eb8cc6 target/i386: remove CPUX86State argument from generator functions
CPUX86State argument would only be used to fetch bytes, but that has to be
done before the generator function is called.  So remove it, and all
temptation together with it.
