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.

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).

It set "aspeed_smc_flash_ops" struct which containing
read and write callbacks to be used when I/O is performed
on the SMC flash region. And it set the valid max_access_size 4

However, the valid max_access_size 4 only support 32 bits CPUs.
To support all ASPEED SMC model, introduce a new
"const MemoryRegionOps *" attribute in AspeedSMCClass and
use it in aspeed_smc_flash_realize function.

3a6c0f0e9d aspeed/smc: support dma start length and 1 byte length unit
DMA length is from 1 byte to 32MB for AST2600 and AST10x0
and DMA length is from 4 bytes to 32MB for AST2500.

In other words, if "R_DMA_LEN" is 0, it should move at least 1 byte
data for AST2600 and AST10x0 and 4 bytes data for AST2500.
To support all ASPEED SOCs, adds dma_start_length parameter to store
the start length, add helper routines function to compute the dma length
and update DMA_LENGTH mask to "1FFFFFF" to support dma 1 byte
length unit for AST2600 and AST1030.
Currently, only supports dma length 4 bytes aligned.

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.

Add a second mapcache for grant mappings. The mapcache for
grants needs to work with XC_PAGE_SIZE granularity since
we can't map larger ranges than what has been granted to us.

Like with foreign mappings (xen_memory), machines using grants
are expected to initialize the xen_grants MR and map it
into their address-map accordingly.

c1996992cc i386/sev: Allow measured direct kernel boot on SNP
In SNP, the hashes page designated with a specific metadata entry
published in AmdSev OVMF.

Therefore, if the user enabled kernel hashes (for measured direct boot),
QEMU should prepare the content of hashes table, and during the
processing of the metadata entry it copy the content into the designated
page and encrypt it.

Note that in SNP (unlike SEV and SEV-ES) the measurements is done in
whole 4KB pages.  Therefore QEMU zeros the whole page that includes the
hashes table, and fills in the kernel hashes area in that page, and then
encrypts the whole page.  The rest of the page is reserved for SEV
launch secrets which are not usable anyway on SNP.

If the user disabled kernel hashes, QEMU pre-validates the kernel hashes
page as a zero page.

f3c30c575d hw/i386/sev: Add function to get SEV metadata from OVMF header
A recent version of OVMF expanded the reset vector GUID list to add
SEV-specific metadata GUID. The SEV metadata describes the reserved
memory regions such as the secrets and CPUID page used during the SEV-SNP
guest launch.

The pc_system_get_ovmf_sev_metadata_ptr() is used to retieve the SEV
metadata pointer from the OVMF GUID list.

a4c2735f35 cpu: move Qemu[Thread|Cond] setup into common code
Aside from the round robin threads this is all common code. By
moving the halt_cond setup we also no longer need hacks to work around
the race between QOM object creation and thread creation.

It is a little ugly to free stuff up for the round robin thread but
better it deal with its own specialises than making the other
accelerators jump through hoops.

408b2b3d9d accel/tcg: Make TCGCPUOps::cpu_exec_halt return bool for whether to halt
The TCGCPUOps::cpu_exec_halt method is called from cpu_handle_halt()
when the CPU is halted, so that a target CPU emulation can do
anything target-specific it needs to do.  (At the moment we only use
this on i386.)

The current specification of the method doesn't allow the target
specific code to do something different if the CPU is about to come
out of the halt state, because cpu_handle_halt() only determines this
after the method has returned.  (If the method called cpu_has_work()
itself this would introduce a potential race if an interrupt arrived
between the target's method implementation checking and
cpu_handle_halt() repeating the check.)

Change the definition of the method so that it returns a bool to
tell cpu_handle_halt() whether to stay in halt or not.

We will want this for the Arm target, where FEAT_WFxT wants to do
some work only for the case where the CPU is in halt but about to
leave it.

b17a26bc4b i386: Support module_id in X86CPUTopoIDs
Add module_id member in X86CPUTopoIDs.

module_id can be parsed from APIC ID, so also update APIC ID parsing
rule to support module level. With this support, the conversions with
module level between X86CPUTopoIDs, X86CPUTopoInfo and APIC ID are
completed.

module_id can be also generated from cpu topology, and before i386
supports "modules" in smp, the default "modules per die" (modules *
clusters) is only 1, thus the module_id generated in this way is 0,
so that it will not conflict with the module_id generated by APIC ID.

3568adc995 i386: Support modules_per_die in X86CPUTopoInfo
Support module level in i386 cpu topology structure "X86CPUTopoInfo".

Since x86 does not yet support the "modules" parameter in "-smp",
X86CPUTopoInfo.modules_per_die is currently always 1.

Therefore, the module level width in APIC ID, which can be calculated by
"apicid_bitwidth_for_count(topo_info->modules_per_die)", is always 0 for
now, so we can directly add APIC ID related helpers to support module
level parsing.

In addition, update topology structure in test-x86-topo.c.

6ddeb0ec8c i386/cpu: Introduce bitmap to cache available CPU topology levels
Currently, QEMU checks the specify number of topology domains to detect
if there's extended topology levels (e.g., checking nr_dies).

With this bitmap, the extended CPU topology (the levels other than SMT,
core and package) could be easier to detect without touching the
topology details.

This is also in preparation for the follow-up to decouple CPUID[0x1F]
subleaf with specific topology level.

a44ea3fa7f hw/i386/pc_sysfw: Alias rather than copy isa-bios region
In the -bios case the "isa-bios" memory region is an alias to the BIOS mapped
to the top of the 4G memory boundary. Do the same in the -pflash case, but only
for new machine versions for migration compatibility. This establishes common
behavior and makes pflash commands work in the "isa-bios" region which some
real-world legacy bioses rely on.

Note that in the sev_enabled() case, the "isa-bios" memory region in the -pflash
case will now also point to encrypted memory, just like it already does in the
-bios case.

When running `info mtree` before and after this commit with
`qemu-system-x86_64 -S -drive \
if=pflash,format=raw,readonly=on,file=/usr/share/qemu/bios-256k.bin` and running
`diff -u before.mtree after.mtree` results in the following changes in the

c0fcd6334f ui/console: Use qemu_dmabuf_new() and free() helpers instead
This commit introduces utility functions for the creation and deallocation
of QemuDmaBuf instances. Additionally, it updates all relevant sections
of the codebase to utilize these new utility functions.

v7: remove prefix, "dpy_gl_" from all helpers
    qemu_dmabuf_free() returns without doing anything if input is null
    (Daniel P. Berrangé <berrange@redhat.com>)
    call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free()
    (Daniel P. Berrangé <berrange@redhat.com>)

v8: Introduction of helpers was removed as those were already added
    by the previous commit

v9: set dmabuf->allow_fences to 'true' when dmabuf is created in
    virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c

    removed unnecessary spaces were accidently added in the patch,
    'ui/console: Use qemu_dmabuf_new() a...'

v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be
     done in qemu_dmabuf_free anyway.
     (Daniel P. Berrangé <berrange@redhat.com>)

v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't
         do it.

     --- 'dmabuf' is now allocated space so it should be freed at the end of
         dbus_scanout_texture

v13: --- Immediately free dmabuf after it is released to prevent possible
         leaking of the ptr
         (Marc-André Lureau <marcandre.lureau@redhat.com>)

     --- Use g_autoptr macro to define *dmabuf for auto clean up instead of
         calling qemu_dmabuf_free
         (Marc-André Lureau <marcandre.lureau@redhat.com>)

v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer
         as it was done because of some misunderstanding (v13).

     --- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL
         to prevent freed dmabuf to be accessed again in case if(fd==-1)break;
         happens (before new dmabuf is allocated). Otherwise, it would cause
         invalid memory access when the same function is executed. Also NULL
         check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).

d0be0ac2c3 hw/i386: move rtc-reset-reinjection command out of hw/rtc
The rtc-reset-reinjection QMP command is specific to x86, other boards do not
have the ACK tracking functionality that is needed for RTC interrupt
reinjection.  Therefore the QMP command is only included in x86, but
qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c
and requires tracking of all created RTC devices.  Move the implementation
to hw/i386, so that 1) it is available even if no RTC device exist
2) the only RTC that exists is easily found in x86ms->rtc.
