Jean-Philippe Brucker 96a664d05c hw/intc/arm_gicv3_cpuif: Tolerate spurious EOIR writes
Commit 382c7160d1 ("hw/intc/arm_gicv3_cpuif: Fix EOIR write access
check logic") added an assert_not_reached() if the guest writes the EOIR
register while no interrupt is active.

It turns out some software does this: EDK2, in
GicV3ExitBootServicesEvent(), unconditionally write EOIR for all
interrupts that it manages. This now causes QEMU to abort when running
UEFI on a VM with GICv3. Although it is UNPREDICTABLE behavior and EDK2
does need fixing, the punishment seems a little harsh, especially since
icc_eoir_write() already tolerates writes of nonexistent interrupt
numbers. Display a guest error and tolerate spurious EOIR writes.

Commit 4e78f3bf35 "esp: defer command completion interrupt on incoming data
transfers" added a version check for use with VMSTATE_*_TEST macros to allow
migration from older QEMU versions. Unfortunately the version check fails to
work in its current form since if the VMStateDescription version_id is
incremented, the test returns false and so the fields are not included in the
outgoing migration stream.

Change the version check to use >= rather == to ensure that migration works
correctly when the ESPState VMStateDescription has version_id > 5.

Commit 799d90d818 "esp: transition to message out phase after SATN and stop

Apply the same logic in esp_do_dma() to do_dma_pdma_cb() so that extended
messages terminated with a PDMA request are accumulated correctly. This allows
the ESP device to respond correctly to the SDTR negotiation initiated by the
NetBSD ESP driver without causing errors and timeouts on boot.

Mark Cave-Ayland 35579b523c esp: revert 75ef849696 "esp: correctly fill bus id with requested lun"
This commit from nearly 10 years ago is now broken due to the improvements
in esp emulation (or perhaps was never correct).  It shows up as a bug
in detecting the CDROM drive under MacOS. The error is caused by the
MacOS CDROM driver sending this CDB with an "S without ATN" command and
without DMA:

    0x12 0x00 0x00 0x00 0x05 0x00 (INQUIRY)

This is a valid INQUIRY command, however with this logic present the 3rd
byte (0x0) is copied over the 1st byte (0x12) which silently converts the
INQUIRY command to a TEST UNIT READY command before passing it to the
QEMU SCSI layer.  Since the TEST UNIT READY command has a zero length
response the MacOS CDROM driver never receives a response and assumes
the CDROM is not present.

The logic was to ignore the IDENTIFY byte and copy the LUN over from
the CDB, which did store the LUN in bits 5-7 of the second byte in
olden times.  This however is all obsolete, so just drop the code.

Mark Cave-Ayland e62a959afd esp: ensure PDMA write transfers are flushed from the FIFO to the target immediately
After each PDMA write transfer the MacOS CDROM driver waits until the FIFO is empty
(i.e. its contents have been written out to the SCSI bus) by polling the FIFO count
register until it reads 0. This doesn't work with the current PDMA write
implementation which waits until either the FIFO is full or the transfer is complete
before invoking the PDMA callback to process the FIFO contents.

Change the PDMA write transfer logic so that the PDMA callback is invoked after each
PDMA write to transfer the FIFO contents to the target buffer immediately, and hence
avoid getting stuck in the FIFO count register polling loop.

Mark Cave-Ayland 6ef2cabc7c esp: handle non-DMA transfers from the target one byte at a time
The initial implementation of non-DMA transfers was based upon analysis of traces
from the MacOS toolbox ROM for handling unaligned reads but missed one key
aspect - during a non-DMA transfer from the target, the bus service interrupt
should be raised for every single byte received from the bus and not just at either
the end of the transfer or when the FIFO is full.

Adjust the non-DMA code accordingly so that esp_do_nodma() is called for every byte
received from the target. This also includes special handling for managing the change
from DATA IN to STATUS phase as this needs to occur when the final byte is read out
from the FIFO, and not at the end of the transfer of the last byte into the FIFO.

Mark Cave-Ayland 880d3089f1 esp: allow non-DMA callback in esp_transfer_data() initial transfer
The current implementation only resumes DMA transfers when incoming data is
received from the target device, but this is also required for non-DMA transfers
with the next set of non-DMA changes.

Rather than duplicate the DMA/non-DMA dispatch logic in the initial transfer
section, update the code so that the initial transfer section can just
fallthrough to the main DMA/non-DMA dispatch logic.

Mark Cave-Ayland af947a3d85 esp: only set ESP_RSEQ at the start of the select sequence
When processing a command to select a target and send a CDB, the ESP device
maintains a sequence step register so that if an error occurs the host can
determine which part of the selection/CDB submission sequence failed.

The old Linux 2.6 driver is really pedantic here: it checks the sequence step
register even if a command succeeds and complains loudly on the console if the
sequence step register doesn't match the expected bus phase and interrupt flags.

This reason this mismatch occurs is because the ESP emulation currently doesn't
update the bus phase until the next TI (Transfer Information) command and so the
cleared sequence step register is considered invalid for the stale bus phase.

Normally this isn't an issue as the host only checks the sequence step register
if an error occurs but the old Linux 2.6 driver does this in several places
causing a large stream of "esp0: STEP_ASEL for tgt 0" messages to appear on the
console during the boot process.

Fix this by not clearing the sequence step register when reading the interrupt
register and clearing the DMA status, so the guest sees a valid sequence step
and bus phase combination at the end of the command phase. No other change is
required since the sequence step register is correctly updated throughout the
selection/CDB submission sequence once one of the select commands is issued.

Maxim Levitsky 06b80795ee block/scsi: correctly emulate the VPD block limits page
When the device doesn't support the VPD block limits page, we emulate it even
for SCSI passthrough.

As a part of the emulation we need to add it to the 'Supported VPD Pages'

The code that does this adds it to the page, but it doesn't increase the length
of the data to be copied to the guest, thus the guest never sees the VPD block
limits page as supported.

Bump the transfer size by 1 in this case.

Gerd Hoffmann 4fa7b4cc50 virtio-gpu: move scanout_id sanity check
Checking scanout_id in virtio_gpu_do_set_scanout() is too late, for the
"resource_id == 0" case (aka disable scanout) the scanout_id is used
unchecked.  Move the check into the callers to fix that.

Dennis Wölfing 05ece98f96 vga: Allow writing VBE_DISPI_ID5 to ID register
The highest VBE_DISPI_INDEX_ID version supported by QEMU is
VBE_DISPI_ID5. But currently QEMU only allows writing values up to
VBE_DISPI_ID4 to the VBE_DISPI_INDEX_ID register.

As a result of this when a lower version is written to this register and
later VBE_DISPI_ID5 is written back, reads from the register will
continue to report the lower version.

Indeed SeaBIOS is doing that during VGA initialization which causes
guests to always read VBE_DISPI_ID0 instead of the correct version.

The GDateTime APIs provided by GLib avoid portability pitfalls, such
as some platforms where 'struct timeval.tv_sec' field is still 'long'
instead of 'time_t'. When combined with automatic cleanup, GDateTime

Jason Wang c33f23a419 vhost-vdpa: don't initialize backend_features
We used to initialize backend_features during vhost_vdpa_init()
regardless whether or not it was supported by vhost. This will lead
the unsupported features like VIRTIO_F_IN_ORDER to be included and set
to the vhost-vdpa during vhost_dev_start. Because the
VIRTIO_F_IN_ORDER is not supported by vhost-vdpa so it won't be
advertised to guest which will break the datapath.

Fix this by not initializing the backend_features, so the
acked_features could be built only from guest features via
vhost_net_ack_features().

Bin Meng 143897b501 hw/riscv: microchip_pfsoc: Support direct kernel boot
At present the Microchip Icicle Kit machine only supports using
'-bios' to load the HSS, and does not support '-kernel' for direct
kernel booting just like other RISC-V machines do. One has to use
U-Boot which is chain-loaded by HSS, to load a kernel for testing.
This is not so convenient.

Adding '-kernel' support together with the existing '-bios', we
follow the following table to select which payload we execute:

  -bios |    -kernel | payload
  ------+------------+--------
      N |          N | HSS
      Y | don't care | HSS
      N |          Y | kernel

This ensures backwards compatibility with how we used to expose
'-bios' to users. When '-kernel' is used for direct boot, '-dtb'
must be present to provide a valid device tree for the board,
as we don't generate device tree.

When direct kernel boot is used, the OpenSBI fw_dynamic BIOS image
is used to boot a payload like U-Boot or OS kernel directly.

Documentation is updated to describe the direct kernel boot. Note
as of today there is still no PolarFire SoC support in the upstream
Linux kernel hence the document does not include instructions for
that. It will be updated in the future.

Nicholas Piggin ac559ecbea spapr: Set LPCR to current AIL mode when starting a new CPU
TCG does not keep track of AIL mode in a central place, it's based on
the current LPCR[AIL] bits. Synchronize the new CPU's LPCR to the
current LPCR in rtas_start_cpu(), similarly to the way the ILE bit is
synchronized.

Open-code the ILE setting as well now that the caller's LPCR is
available directly, there is no need for the indirection.

Without this, under both TCG and KVM, adding a POWER8/9/10 class CPU
with a new core ID after a modern Linux has booted results in the new
CPU's LPCR missing the LPCR[AIL]=0b11 setting that the other CPUs have.
This can cause crashes and unexpected behaviour.

Shivaprasad G Bhat f93c8f148c spapr: nvdimm: Forward declare and move the definitions
The subsequent patches add definitions which tend to get
the compilation to cyclic dependency. So, prepare with
forward declarations, move the definitions and clean up.

Mahesh Salgaonkar ac9ef66832 spapr: Fix EEH capability issue on KVM guest for PCI passthru
With upstream kernel, especially after commit 98ba956f6a389
("powerpc/pseries/eeh: Rework device EEH PE determination") we see that KVM
guest isn't able to enable EEH option for PCI pass-through devices anymore.

[root@atest-guest ~]# dmesg | grep EEH
[    0.032337] EEH: pSeries platform initialized
[    0.298207] EEH: No capable adapters found: recovery disabled.
[root@atest-guest ~]#

So far the linux kernel was assuming pe_config_addr equal to device's
config_addr and using it to enable EEH on the PE through ibm,set-eeh-option
RTAS call. Which wasn't the correct way as per PAPR. The linux kernel
commit 98ba956f6a389 fixed this flow. With that fixed, linux now uses PE
config address returned by ibm,get-config-addr-info2 RTAS call to enable
EEH option per-PE basis instead of per-device basis. However this has
uncovered a bug in qemu where ibm,set-eeh-option is treating PE config
address as per-device config address.

Hence in qemu guest with recent kernel the ibm,set-eeh-option RTAS call
fails with -3 return value indicating that there is no PCI device exist for
the specified PE config address. The rtas_ibm_set_eeh_option call uses
pci_find_device() to get the PC device that matches specific bus and devfn
extracted from PE config address passed as argument. Thus it tries to map
the PE config address to a single specific PCI device 'bus->devices[devfn]'
which always results into checking device on slot 0 'bus->devices[0]'.
This succeeds when there is a pass-through device (vfio-pci) present on
slot 0. But in cases where there is no pass-through device present in slot
0, but present in non-zero slots, ibm,set-eeh-option call fails to enable
the EEH capability.

hw/ppc/spapr_pci_vfio.c: spapr_phb_vfio_eeh_set_option()
   case RTAS_EEH_ENABLE: {
        PCIHostState *phb;
        PCIDevice *pdev;

        /*
         * The EEH functionality is enabled on basis of PCI device,
         * instead of PE. We need check the validity of the PCI
         * device address.
         */
        phb = PCI_HOST_BRIDGE(sphb);
        pdev = pci_find_device(phb->bus,
                               (addr >> 16) & 0xFF, (addr >> 8) & 0xFF);
        if (!pdev || !object_dynamic_cast(OBJECT(pdev), "vfio-pci")) {
            return RTAS_OUT_PARAM_ERROR;
        }

hw/pci/pci.c:pci_find_device()

PCIDevice *pci_find_device(PCIBus *bus, int bus_num, uint8_t devfn)
{
    bus = pci_find_bus_nr(bus, bus_num);

    if (!bus)
        return NULL;

    return bus->devices[devfn];
}

This patch fixes ibm,set-eeh-option to check for presence of any PCI device
(vfio-pci) under specified bus and enable the EEH if found. The current
code already makes sure that all the devices on that bus are from same
iommu group (within same PE) and fail very early if it does not.

After this fix guest is able to find EEH capable devices and enable EEH
recovery on it.

[root@atest-guest ~]# dmesg | grep EEH
[    0.048139] EEH: pSeries platform initialized
[    0.405115] EEH: Capable adapter found: recovery enabled.

Greg Kurz 3bf0844f3b spapr: Don't hijack current_machine->boot_order
QEMU 6.0 moved all the -boot variables to the machine. Especially, the
removal of the boot_order static changed the handling of '-boot once'
from:

    if (boot_once) {
        qemu_boot_set(boot_once, &error_fatal);
        qemu_register_reset(restore_boot_order, g_strdup(boot_order));
    }

to

    if (current_machine->boot_once) {
        qemu_boot_set(current_machine->boot_once, &error_fatal);
        qemu_register_reset(restore_boot_order,
                            g_strdup(current_machine->boot_order));
    }

This means that we now register as subsequent boot order a copy
of current_machine->boot_once that was just set with the previous
call to qemu_boot_set(), i.e. we never transition away from the
once boot order.

It is certainly fragile^Wwrong for the spapr code to hijack a
field of the base machine type object like that. The boot order
rework simply turned this software boundary violation into an
actual bug.

Have the spapr code to handle that with its own field in
SpaprMachineState. Also kfree() the initial boot device
string when "once" was used.

Daniel P. Berrangé b7c290177c i386: use better matching family/model/stepping for 'qemu64' CPU
The 'qemu64' CPUID currently reports a family/model/stepping that
approximately corresponds to an AMD K7 vintage architecture.
The K7 series predates the introduction of 64-bit support by AMD
in the K8 series. This has been reported to lead to LLVM complaints
about generating 64-bit code for a 32-bit CPU target

  LLVM ERROR: 64-bit code requested on a subtarget that doesn't support it!

It appears LLVM looks at the family/model/stepping, despite qemu64
reporting it is 64-bit capable.

This patch changes 'qemu64' to report a CPUID with the family, model
and stepping taken from a

 AMD Athlon(tm) 64 X2 Dual Core Processor 4000+

which is one of the first 64-bit AMD CPUs.

Closes https://gitlab.com/qemu-project/qemu/-/issues/191

Ruimei Yan fc967aad40 hw/usb: hcd-xhci-pci: Fix spec violation of IP flag for MSI/MSI-X
Per xHCI spec v1.2 chapter 4.17.5 page 296:

  If MSI or MSI-X interrupts are enabled, Interrupt Pending (IP)
  shall be cleared automatically when the PCI dword write generated
  by the interrupt assertion is complete.

Currently QEMU does not clear the IP flag in the MSI / MSI-X mode.
This causes subsequent spurious interrupt to be delivered to guests.
To solve this, we change the xhci intr_raise() hook routine to have
a bool return value that is passed to its caller (the xhci core),
with true indicating that IP should be self-cleared.

Fixes: 62c6ae04cf ("xhci: Initial xHCI implementation")
Fixes: 4c47f80063 ("xhci: add msix support")

Ruimei Yan 3c6151cd11 hw/usb: hcd-xhci-pci: Raise MSI/MSI-X interrupts only when told to
At present MSI / MSI-X interrupts are triggered regardless of the
irq level. We should have checked the level to determine whether
the interrupt needs to be delivered.

The level check logic was present in early versions of the xhci
model, but got dropped later by a rework of interrupt handling
under commit 4c4abe7cc9 ("xhci: rework interrupt handling").

Add helper functions to create a dmabuf for a resource and mmap it.
Also, introduce the fields blob and blob_size so that these helpers
can start to use them but the full picture will emerge only after
adding create_blob API in patch 8 of this series.

To be able to create a dmabuf using the udmabuf driver, Qemu needs
to be lauched with the memfd memory backend like this:

qemu-system-x86_64 -m 8192m -object memory-backend-memfd,id=mem1,size=8192M
-machine memory-backend=mem1

Laurent Vivier 1e157667d7 virtio-net: failover: add missing remove_migration_state_change_notifier()
In the failover case configuration, virtio_net_device_realize() uses an
add_migration_state_change_notifier() to add a state notifier, but this
notifier is not removed by the unrealize function when the virtio-net
card is unplugged.

If the card is unplugged and a migration is started, the notifier is
called and as it is not valid anymore QEMU crashes.

This patch fixes the problem by adding the
remove_migration_state_change_notifier() in virtio_net_device_unrealize().

The problem can be reproduced with:

  $ qemu-system-x86_64 -enable-kvm -m 1g -M q35 \
    -device pcie-root-port,slot=4,id=root1 \
    -device pcie-root-port,slot=5,id=root2 \
    -device virtio-net-pci,id=net1,mac=52:54:00:6f:55:cc,failover=on,bus=root1 \
    -monitor stdio disk.qcow2
  (qemu) device_del net1
  (qemu) migrate "exec:gzip -c > STATEFILE.gz"

Guenter Roeck f607dce2ed hw/net/imx_fec: return 0xffff when accessing non-existing PHY
If a PHY does not exist, attempts to read from it should return 0xffff.
Otherwise the Linux kernel will believe that a PHY is there and select
the non-existing PHY. This in turn will result in network errors later
on since the real PHY is not selected or configured.

Since reading from or writing to a non-existing PHY is not an emulation
error, replace guest error messages with traces.

virtio code.

To be able to later extract the cpu_get_phys_page_debug() and
cpu_asidx_from_attrs() handlers from CPUClass, un-inline them
from "hw/core/cpu.h".

Philippe Mathieu-Daudé df4fd7d5c8 cpu: Split as cpu-common / cpu-sysemu
The current cpu.c contains sysemu-specific methods.
To avoid building them in user-mode builds, split the
current cpu.c as cpu-common.c / cpu-sysemu.c.

Start by moving cpu_get_crash_info().

Kit Westneat b802d14dc6 hw/scsi: Fix sector translation bug in scsi_unmap_complete_noio
check_lba_range expects sectors to be expressed in original qdev blocksize, but
scsi_unmap_complete_noio was translating them to 512 block sizes, which was
causing sense errors in the larger LBAs in devices using a 4k block size.

Philippe Mathieu-Daudé cfa1f4bcee hw/mem/nvdimm: Use Kconfig 'imply' instead of 'depends on'
Per the kconfig.rst:

  A device should be listed [...] ``imply`` if (depending on
  the QEMU command line) the board may or  may not be started
  without it.

This is the case with the NVDIMM device, so use the 'imply'
weak reverse dependency to select the symbol.

Volker Rümelin 9d74e6c3e7 pckbd: clear outport_present in outer pre_load()
The variable outport_present is a flag to show if the outport
subsection was loaded. Clear the outport_present flag in the
outer pre_load() function. This method is recommended in the QEMU
manual for developers in the chapter "Migration, Subsections".
