8e25dddaf9 hw/dma: Add a trace log for a description loading failure
Due to a description loading failure, adding a trace log makes observing
the DMA behavior easy.

e6b45b6bb9 hw/dma: Enhance error handling in loading description
Loading a description from memory may cause a bus-error. In this
case, the DMA should stop working, set the error flag, and return
the failure value.

When calling the loading a description function, it should be noticed
that the function may return a failure value. Breaking the loop in this
case is one of the possible ways to handle it.

6476902740 target/i386: convert SHLD/SHRD to new decoder
Use the same flag generation code as SHL and SHR, but use
the existing gen_shiftd_rm_T1 function to compute the result
as well as CC_SRC.

Decoding-wise, SHLD/SHRD by immediate count as a 4 operand
instruction because s->T0 and s->T1 actually occupy three op
slots.  The infrastructure used by opcodes in the 0F 3A table
works fine.

SHLD/SHRD can have 3 register operands - s->T0, s->T1 and either
1 or CL - and therefore decode->op[2] is taken by the low part
of the register being shifted.  Pass X86_OP_* to gen_shift_count
from its current callers and hardcode cpu_regs[R_ECX] as the
shift count.

7436db1063 aspeed/soc: fix incorrect dram size for AST2700
AST2700 dram size calculation is not back compatible AST2600.
According to the DDR capacity hardware behavior,
if users write the data to the address which is beyond the ram size,
it would write the data to the "address % ram_size".
For example:
a. sdram base address "0x4 00000000"
b. sdram size 1 GiB
The available address range is from "0x4 00000000" to "0x4 3FFFFFFF".
If users write 0x12345678 to address "0x5 00000000",
the value of DRAM address 0 (base address 0x4 00000000) will be 0x12345678.

Add aspeed_soc_ast2700_dram_init to calculate the dram size and add
memory I/O whose address range is from "max_ram_size - ram_size" to max_ram_size
and its read/write handler to emulate DDR capacity hardware behavior.

9270799210 aspeed: Add an AST2700 eval board
AST2700 CPU is ARM Cortex-A35 which is 64 bits.
Add TARGET_AARCH64 to build this machine.

According to the design of ast2700, it has a bootmcu(riscv-32) which
is used for executing SPL.
Then, CPUs(cortex-a35) execute u-boot, kernel and rofs.

Currently, qemu not support emulate two CPU architectures
at the same machine. Therefore, qemu will only support
to emulate CPU(cortex-a35) side for ast2700

5dd883ab06 aspeed/soc: Add AST2700 support
Initial definitions for a simple machine using an AST2700 SOC (Cortex-a35 CPU).

AST2700 SOC and its interrupt controller are too complex to handle
in the common Aspeed SoC framework. We introduce a new ast2700
class with instance_init and realize handlers.

AST2700 is a 64 bits quad core cpus and support 8 watchdog.
Update maximum ASPEED_CPUS_NUM to 4 and ASPEED_WDTS_NUM to 8.
In addition, update AspeedSocState to support scuio, sli, sliio and intc.

Add TYPE_ASPEED27X0_SOC machine type.

The SDMC controller is unlocked at SPL stage.
At present, only supports to emulate booting
start from u-boot stage. Set SDMC controller
unlocked by default.

In INTC, each interrupt of INT 128 to INT 136 combines 32 interrupts.
It connect GICINT IRQ GPIO-OUTPUT pins to GIC device with irq 128 to 136.
And, if a device irq is 128 to 136, its irq GPIO-OUTPUT pin is connected to
GICINT or-gates instead of GIC device.

d831c5fd86 aspeed/intc: Add AST2700 support
AST2700 interrupt controller(INTC) provides hardware interrupt interfaces
to interrupt of processors PSP, SSP and TSP. In INTC, each interrupt of
INT 128 to INT136 combines 32 interrupts.

Introduce a new aspeed_intc class with instance_init and realize handlers.

So far, this model only supports GICINT128 to GICINT136.
It creates 9 GICINT or-gates to connect 32 interrupts sources
from GICINT128 to GICINT136 as IRQ GPIO-OUTPUT pins.
Then, this model registers IRQ handler with its IRQ GPIO-INPUT pins which
connect to GICINT or-gates. And creates 9 GICINT IRQ GPIO-OUTPUT pins which
connect to GIC device with GIC IRQ 128 to 136.

If one interrupt source from GICINT128 to GICINT136
set irq, the OR-GATE irq callback function is called and set irq to INTC by
OR-GATE GPIO-OUTPUT pins. Then, the INTC irq callback function is called and
set irq to GIC by its GICINT IRQ GPIO-OUTPUT pins. Finally, the GIC irq
callback function is called and set irq to CPUs and
CPUs execute Interrupt Service Routine (ISR).

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.

c1dfd12168 migration/multifd: Switch to no compression when no hardware support
Send raw packets over if UADK hardware support is not available. This is to
satisfy  Qemu qtest CI which may run on platforms that don't have UADK
hardware support. Subsequent patch will add support for uadk migration
qtest.

08b82d207d tests/migration-test: add qpl compression test
add qpl to compression method test for multifd migration

the qpl compression supports software path and hardware
path(IAA device), and the hardware path is used first by
default. If the hardware path is unavailable, it will
automatically fallback to the software path for testing.

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.

34e104b897 migration/multifd: implement initialization of qpl compression
during initialization, a software job is allocated to each channel
for software path fallabck when the IAA hardware is unavailable or
the hardware job submission fails. If the IAA hardware is available,
multiple hardware jobs are allocated for batch processing.
