Jamin Lin 2095468d2c hw/net:ftgmac100: update TX and RX packet buffers address to 64 bits
ASPEED AST2700 SOC is a 64 bits quad core CPUs (Cortex-a35)
And the base address of dram is "0x4 00000000" which
is 64bits address.

It have "TXDES 2" and "RXDES 2" to save the high part
physical address of packet buffer.
Ex: TX packet buffer address [34:0]
The "TXDES 2" bits [18:16] which corresponds the bits [34:32]
of the 64 bits address of the TX packet buffer address
and "TXDES 3" bits [31:0] which corresponds the bits [31:0]
of the 64 bits address of the TX packet buffer address.

Update TX and RX packet buffers address type to
64 bits for dram 64 bits address DMA support.

Jamin Lin 578c6e9ed5 hw/net:ftgmac100: introduce TX and RX ring base address high registers to support 64 bits
ASPEED AST2700 SOC is a 64 bits quad core CPUs (Cortex-a35)
And the base address of dram is "0x4 00000000" which
is 64bits address.

It have "Normal Priority Transmit Ring Base Address Register High(0x17C)",
"High Priority Transmit Ring Base Address Register High(0x184)" and
"Receive Ring Base Address Register High(0x18C)" to save the high part physical
address of descriptor manager.
Ex: TX descriptor manager address [34:0]
The "Normal Priority Transmit Ring Base Address Register High(0x17C)"
bits [2:0] which corresponds the bits [34:32] of the 64 bits address of
the TX ring buffer address.
The "Normal Priority Transmit Ring Base Address Register(0x20)" bits [31:0]
which corresponds the bits [31:0] of the 64 bits address
of the TX ring buffer address.

Introduce a new sub region which size is 0x100 for the set of new registers
and map it at 0x100 in the container region.
This sub region range is from 0x100 to 0x1ff.

Introduce a new property and object attribute to activate the region for new registers.
Introduce a new memop handlers for the new register read and write.

Jamin Lin 0b51fd0f99 hw/net:ftgmac100: update ring base address to 64 bits
Update TX and RX ring base address data type to uint64_t for
64 bits dram address DMA support.

Both "Normal Priority Transmit Ring Base Address Register(0x20)" and
"Receive Ring Base Address Register (0x24)" are used for saving the
low part physical address of descriptor manager.

Therefore, changes to set TX and RX descriptor manager address bits [31:0]
in ftgmac100_read and ftgmac100_write functions.

Incrementing the version of vmstate to 2.

Jamin Lin eec2f9cc69 hw/net:ftgmac100: update memory region size to 64KB
According to the datasheet of ASPEED SOCs,
one MAC controller owns 128KB of register space for AST2500.
However, one MAC controller only owns 64KB of register space for AST2600
and AST2700. It set the memory region size 128KB and it occupied another
controllers Address Spaces.

Update one MAC controller memory region size to 0x1000
because AST2500 did not use register spaces over than 64KB.

Introduce a new container region size to 0x1000 and its range
is from 0 to 0xfff. This container is mapped a sub region
for the current set of register.
This sub region range is from 0 to 0xff.

Akihiko Odaki 6a67577d80 hw/pci: Replace -1 with UINT32_MAX for romsize
romsize is an uint32_t variable. Specifying -1 as an uint32_t value is
obscure way to denote UINT32_MAX.

Worse, if int is wider than 32-bit, it will change the behavior of a
construct like the following:
romsize = -1;
if (romsize != -1) {
    ...
}

When -1 is assigned to romsize, -1 will be implicitly casted into
uint32_t, resulting in UINT32_MAX. On contrary, when evaluating
romsize != -1, romsize will be casted into int, and it will be a
comparison of UINT32_MAX and -1, and result in false.

Replace -1 with UINT32_MAX for statements involving the variable to
clarify the intent and prevent potential breakage.

Cédric Le Goater 1b889d6e39 virtio-iommu: Clear IOMMUDevice when VFIO device is unplugged
When a VFIO device is hoplugged in a VM using virtio-iommu, IOMMUPciBus
and IOMMUDevice cache entries are created in the .get_address_space()
handler of the machine IOMMU device. However, these entries are never
destroyed, not even when the VFIO device is detached from the machine.
This can lead to an assert if the device is reattached again.

When reattached, the .get_address_space() handler reuses an
IOMMUDevice entry allocated when the VFIO device was first attached.
virtio_iommu_set_host_iova_ranges() is called later on from the
.set_iommu_device() handler an fails with an assert on 'probe_done'
because the device appears to have been already probed when this is
not the case.

The IOMMUDevice entry is allocated in pci_device_iommu_address_space()
called from under vfio_realize(), the VFIO PCI realize handler. Since
pci_device_unset_iommu_device() is called from vfio_exitfn(), a sub
function of the PCIDevice unrealize() handler, it seems that the
.unset_iommu_device() handler is the best place to release resources
allocated at realize time. Clear the IOMMUDevice cache entry there to
fix hotplug.

Stefano Garzarella 7aa6492401 virtio: remove virtio_tswap16s() call in vring_packed_event_read()
Commit d152cdd6f6 ("virtio: use virtio accessor to access packed event")
switched using of address_space_read_cached() to virito_lduw_phys_cached()
to access packed descriptor event.

When we used address_space_read_cached(), we needed to call
virtio_tswap16s() to handle the endianess of the field, but
virito_lduw_phys_cached() already handles it internally, so we no longer
need to call virtio_tswap16s() (as the commit had done for `off_wrap`,
but forgot for `flags`).

Nicolin Chen 5786827f47 hw/arm/virt-acpi-build: Fix id_count in build_iort_id_mapping
It's observed that Linux kernel booting with the VM reports a "conflicting
mapping for input ID" FW_BUG.

The IORT doc defines "Number of IDs" to be "the number of IDs in the range
minus one", while virt-acpi-build.c simply stores the number of IDs in the
id_count without the "minus one". Meanwhile, some of the callers pass in a
0xFFFF following the spec. So, this is a mismatch between the function and
its callers.

Fix build_iort_id_mapping() by internally subtracting one from the pass-in
@id_count. Accordingly make sure that all existing callers pass in a value
without the "minus one", i.e. change all 0xFFFFs to 0x10000s.

Also, add a few lines of comments to highlight this change along with the
referencing document for this build_iort_id_mapping().

David Woodhouse 93c76555d8 hw/i386/fw_cfg: Add etc/e820 to fw_cfg late
In e820_add_entry() the e820_table is reallocated with g_renew() to make
space for a new entry. However, fw_cfg_arch_create() just uses the
existing e820_table pointer. This leads to a use-after-free if anything
adds a new entry after fw_cfg is set up.

Shift the addition of the etc/e820 file to the machine done notifier, via
a new fw_cfg_add_e820() function.

Also make e820_table private and use an e820_get_table() accessor function
for it, which sets a flag that will trigger an assert() for any *later*
attempts to add to the table.

Make e820_add_entry() return void, as most callers don't check for error
anyway.

Philippe Mathieu-Daudé 617c5a7345 hw/sd/sdcard: Remove SEND_DSR dead case (CMD4)
The CSD::CSR_IMP bit defines whether the Driver Stage
Register (DSR) is implemented or not. We do not set
this bit in CSD:

    static void sd_set_csd(SDState *sd, uint64_t size)
    {
        ...
        if (size <= SDSC_MAX_CAPACITY) { /* Standard Capacity SD */
            ...
            sd->csd[6] = 0xe0 |     /* Partial block for read allowed */
                ((csize >> 10) & 0x03);
            ...
        } else {                    /* SDHC */
            ...
            sd->csd[6] = 0x00;
            ...
        }
        ...
    }

The sd_normal_command() switch case for the SEND_DSR
command do nothing and fallback to "illegal command".
Since the command is mandatory (although the register
isn't...) call the sd_cmd_unimplemented() handler.

Thomas Huth c1991c0984 hw/intc/s390_flic: Fix interrupt controller migration on s390x with TCG
Migration of a s390x guest with TCG was long known to be very unstable,
so the tests in tests/qtest/migration-test.c are disabled if running
with TCG instead of KVM.

Nicholas Piggin did a great analysis of the problem:

"The flic pending state is not migrated, so if the machine is migrated
 while an interrupt is pending, it can be lost. This shows up in
 qtest migration test, an extint is pending (due to console writes?)
 and the CPU waits via s390_cpu_set_psw and expects the interrupt to
 wake it. However when the flic pending state is lost, s390_cpu_has_int
 returns false, so s390_cpu_exec_interrupt falls through to halting
 again."

Thus let's finally migrate the pending state, and to be on the safe
side, also the other state variables of the QEMUS390FLICState structure.

Zheyu Ma 87511bb878 hw/gpio/aspeed: Add reg_table_count to AspeedGPIOClass
ASan detected a global-buffer-overflow error in the aspeed_gpio_read()
function. This issue occurred when reading beyond the bounds of the
reg_table.

To enhance the safety and maintainability of the Aspeed GPIO code, this commit
introduces a reg_table_count member to the AspeedGPIOClass structure. This
change ensures that the size of the GPIO register table is explicitly tracked
and initialized, reducing the risk of errors if new register tables are
introduced in the future.

Zhao Liu e05ee2994a i386/apic: Add hint on boot failure because of disabling x2APIC
Currently, the Q35 supports up to 4096 vCPUs (since v9.0), but for TCG
cases, if x2APIC is not actively enabled to boot more than 255 vCPUs (
e.g., qemu-system-i386 -M pc-q35-9.0 -smp 666), the following error is
reported:

Unexpected error in apic_common_set_id() at ../hw/intc/apic_common.c:449:
qemu-system-i386: APIC ID 255 requires x2APIC feature in CPU
Aborted (core dumped)

This error can be resolved by setting x2apic=on in -cpu. In order to
better help users deal with this scenario, add the error hint to
instruct users on how to enable the x2apic feature. Then, the error
report becomes the following:

Unexpected error in apic_common_set_id() at ../hw/intc/apic_common.c:448:
qemu-system-i386: APIC ID 255 requires x2APIC feature in CPU
Try x2apic=on in -cpu.
Aborted (core dumped)

Note since @errp is &error_abort, error_append_hint() can't be applied
on @errp. And in order to separate the exact error message from the
(perhaps effectively) hint, adding a hint via error_append_hint() is
also necessary. Therefore, introduce @local_error in
apic_common_set_id() to handle both the error message and the error
hint.

Jiqian Chen 5d98e18823 virtio-pci: implement No_Soft_Reset bit
In current code, when guest does S3, virtio-gpu are reset due to the
bit No_Soft_Reset is not set. After resetting, the display resources
of virtio-gpu are destroyed, then the display can't come back and only
show blank after resuming.

Implement No_Soft_Reset bit of PCI_PM_CTRL register, then guest can check
this bit, if this bit is set, the devices resetting will not be done, and
then the display can work after resuming.

No_Soft_Reset bit is implemented for all virtio devices, and was tested
only on virtio-gpu device. Set it false by default for safety.

Ira Weiny e6c9c9e7f4 hw/cxl: Fix read from bogus memory
Peter and coverity report:

	We've passed '&data' to address_space_write(), which means "read
	from the address on the stack where the function argument 'data'
	lives", so instead of writing 64 bytes of data to the guest ,
	we'll write 64 bytes which start with a host pointer value and
	then continue with whatever happens to be on the host stack
	after that.

Indeed the intention was to write 64 bytes of data at the address given.

Fix the parameter to address_space_write().

All DPA ranges in the DC regions are invalid to access until an extent
covering the range has been successfully accepted by the host. A bitmap
is added to each region to record whether a DC block in the region has

When a DC extent is accepted, all the bits representing the blocks in the
extent are set, which will be cleared when the extent is released.

Fan Ni d0b9b28a5b hw/cxl/events: Add qmp interfaces to add/release dynamic capacity extents
To simulate FM functionalities for initiating Dynamic Capacity Add
(Opcode 5604h) and Dynamic Capacity Release (Opcode 5605h) as in CXL spec
r3.1 7.6.7.6.5 and 7.6.7.6.6, we implemented two QMP interfaces to issue
add/release dynamic capacity extents requests.

With the change, we allow to release an extent only when its DPA range
is contained by a single accepted extent in the device. That is to say,
extent superset release is not supported yet.

1. Add dynamic capacity extents:

For example, the command to add two continuous extents (each 128MiB long)
to region 0 (starting at DPA offset 0) looks like below:

{ "execute": "qmp_capabilities" }

{ "execute": "cxl-add-dynamic-capacity",
  "arguments": {
      "path": "/machine/peripheral/cxl-dcd0",
      "host-id": 0,
      "selection-policy": "prescriptive",
      "region": 0,
      "extents": [
      {
          "offset": 0,
          "len": 134217728
      },
      {
          "offset": 134217728,
          "len": 134217728
      }
      ]
  }
}

2. Release dynamic capacity extents:

For example, the command to release an extent of size 128MiB from region 0
(DPA offset 128MiB) looks like below:

{ "execute": "cxl-release-dynamic-capacity",
  "arguments": {
      "path": "/machine/peripheral/cxl-dcd0",
      "host-id": 0,
      "removal-policy":"prescriptive",
      "region": 0,
      "extents": [
      {
          "offset": 134217728,
          "len": 134217728
      }
      ]
  }
}

Add Dynamic Capacity Response (Opcode 4802h) 8.2.9.9.9.3, and
Release Dynamic Capacity (Opcode 4803h) 8.2.9.9.9.4.

For the process of the above two commands, we use two-pass approach.
Pass 1: Check whether the input payload is valid or not; if not, skip
        Pass 2 and return mailbox process error.
Pass 2: Do the real work--add or release extents, respectively.
